if it doesn't agree with experiment, its wrong.

Topical Problems in Fluid Mechanics - 2015


The Bernoulli equation and nanochannels



Flow through nanochannels of CNTs is observed to be 2-5 orders of magnitude higher than predicted by the Hagen-Poiseuille equation. CNT stands for carbon nanotube. However, the disparity with experiment cannot be explained by slip at the wall. In this regard, MD simulations of liquid argon valid by QM show flow enhancement to occur because the viscosity vanishes in nanochannels. QM stands for quantum mechanics. See Press Release and Paper

Vanishing viscosity occurs because QED conserves the viscous heat in the nanochannel by creating EM radiation that ionizes the fluid molecules to produces a flow of charged atoms as depicted in the above figure. The charged atoms.under Coulomb repulsion separate more than usual to give a vanishing viscosity. QED induced charged flow in nanochannels should therefore approach rhe frictionless flow given by the Bernoulli equation.

The Bernoulli equation for the mass flow through nanochannels follows from the QED energy equation that excludes temperature changes as required by QM. Indeed, the Bernoulli equation provides a reasonable QM approximation to the flow in nanochannels that avoids the complexity of MD solutions. With the exception of water, the measured flow is close to but less than that predicted by the Bernoulli equation. See data in Paper on "The end of nanochannels"

The frictionless Bernoulli equation is far simpler than performing MD simulations, even if one sets aside the fact that standard MD programs give meaningless results because of their QM invalidity. However, if MD programs are corrected for QM, valid MD solutions for nanochannel flow may be obtained but still the MD cannot be justified compared to the utter simplicity of the Bernoulli equation.

Flow of Fluids and Solids at the Nanoscale 


Flow of fluids in nanochannels simulated by MD follows classical physics, but does not agree with experiments. MD stands for molecular dynamics. The Hagen-Poiseuille equation cannot explain the dramatic increase in flow found in nanochannels. Even if slip is assumed at the wall, the calculated slip-lengths necessary to explain the flow enhancement exceed the typical slip on non-wetting surfaces by 2 to 3 orders of magnitude. See Topical Problems in Fluid Mechanics above.

In solids, classical physics underlying kMC cannot explain how solid crystals in a nanotube under the influence of an electric current flow through a constriction that is smaller than the crystal itself as shown above. kMC stands for kinetic Monte Carlo. At the nanoscale the fluid or solid atoms are placed under EM confinement by that by QM requires their heat capacity to vanish thereby precluding the conservation of the heat of viscous frictional heat by the usual increase in temperature. EM stands for electromagnetic and QM for quantum mechanics. Hence, both MD and kMC based in classical physics that assume the atoms have heat capacity require modification for application at the nanoscale.  Conservation of the heat at the nanoscale proceeds by QED inducing creation of EM radiation that ionizes the atoms to cause separation under Coulomb charge repulsion. QED stands for quantum electrodynamics.

MD simulations of liquid argon flow in a nanochannel using a discrete 2D model show the viscosity to vanish suggests the flow is upper bound by the frictionless Bernoulli equation, the simplified extension of which to the  flow of a solid crystal through a nanotube suggests the solid, like the fluid moves as a loosely bound collection of charged atoms.

 QED Induced UV Radiation to Supersede LED's ?

 Today, LED UV lamps are thought to hold the future in disinfection. LEDs stand for light emitting diodes. LED lamps run coolder than the traditional metal halide lamps as shown held in the fingers of a hand. Regardless, LED's still require a source of electrical power. LED lamps in the UV-A do have a high EQE, but in the UV-C are limited to EQE of a few percent. EQE stands for external quantum efficiency. Since UV-C is requred for disinfection of water pathogens and the Ebola virus, LED's are not expected to impact the disinfection market until 2017/2018.   In contrast, the QED drinking bowl has 100% efficiency, but is limited by low body heat.  

However, the QED induced light may also compete wtih LED's operating int the VIS. Indeed, batteries may not be necessary to drive the LEDs as shown in a hand-held flashlight recently built based on Peltier cells. A comparison between QED and LEDs is given in Presentation


QED Disinfection of Future

Public Transportation in Hong Kong



Today, infectious diseases including SARS and H1N1 continue to haunt Hong Kong. SARS stands for severe acute respiratory syndrome and H1N1 for human swine flu virus. Since 2003, SARS was identified by the WHO as a corona virus family never before seen in humans. SARS is spread by droplets from sneezing and coughing, but may be transmitted by touching contaminated objects. In fact, infectious diseases are usually transmitted through the hands by touching public surfaces. The hands then pass the virus into our bodies upon rubbing our eyes, nose or mouth before washing our hands. In Hong Kong, over 2.5 million commuters use the public transit system every day, and can easily spread infectious viruses to each other by contacting grab poles and handrails commonly used to hold and avoid falling under abrupt train car and bus motions. In this regard, the Hong Kong authority constantly reminds commuters through automated announcements to hold the handrail and grab poles when the train or bus is moving.  Regardless, avoiding touching handrails and grab poles is almost impossible making the transmission of infectious viruses by contacting public surfaces a virtual certainty as shown below.  
 

In 2006, handrails in Hong Kong trains were disinfected by applying a spray of NSTDC to public surfaces to avoid the transmission of infectious viruses. NSTDC stands for nano silver-titanium dioxide coating.  All escalator handrails, the buttons on ticket issuing machines and all handrails and buttons in elevators including grab poles in train cars and buses were coated. More recently in 2010, an anti-microbial coating was developed that is thought to set a new standard in the disinfection of infectious viruses. Transparent, colorless and odorless, this smart coating can sustain surface disinfection by simply spraying on public surfaces. Compared with conventional disinfecting coatings, the smart coating is effective for at least 30 days. Test results show the smart coating can kill 99.9% of bacteria within 1 minute and 99% of the H1N1 virus within 3 minutes. The effectiveness of the smart coating is significantly longer than with conventional disinfectants, many of which will lose their function as they evaporate. On the other hand, laboratory tests showed smart coatings are indeed capable of long-term disinfection with 100% effectiveness even after 30 days. The smart coating is not permanent and can be removed by washing off with detergent-in-water solution.

However, spray coatings of handrails and grab poles offer only a temporary solution. Future public transport systems may require redesigning the grab poles and handrails with permanent coatings. Moreover, the sprayed coatings containing colloidal silver are claimed non-toxic, but nano-silver that comes off and enters the body damages the DNA and can cause cancer.  Alternative handrail and grab pole designs using permanent nano-coatings emitting UV-C radiation are suggested.

With regard to hand poles, QED induced EM radiation emitted from the surface is produced from electrical heaters provided inside the poles is proposed to provide a steady source of UV-C from which ALL infectious viruses may be disinfected.  QED stands for quantum electrodynamics, EM for electromagnetic, and UV-C for ultraviolet radiation at 254 nm. During fabrication, the grab poles would be provided with a permanent 50-60 nm ZnO coating that can be periodically cleaned to minimize pathogen residue. The UV-C from a typical grab pole arrangement is illustrated below, but the electrical heaters inside the poles are not shown.



On the other hand, QED disinfection of hand rails on escalators as shown above does not require electrical heaters as frictional heating of running the hand rail is sufficient to produce the UV-C. Application of nano coating of zinc oxide or titanium dioxide on the handrail surface is required for QED to continuously create the UV-C to disinfect the handrail. The UV-C is depicted to be emitted from the hand rail shown in the above figure of an escalator. 

In summary, hand rails and poles in future public transit train cars and buses disinfect infectious viruses as the heat supplied or generated internally is transferred to the surface of zinc oxide or titanium dioxide nano coatings. Because of quantum mechanics, the supplied heat cannot increase the temperature of the nano coating as its heat capacity vanishes under TIR confinement. TIR stands for total internal reflection. Instead, the heat is conserved by QED inducing its conversion to EM radiation. The TIR confinement only occurs as the heat flows into the nano-coating. The TIR wavelength λ of the EM radiation is, λ  = 2 n d, where, n and d are the refractive index and thickness of the coating. But TIR requires the coating have a refractive index > the surroundings which is satisfied for zinc oxide having n = 2.4 on steel poles having n = 1.5. Hence, QED induces the creation of EM radiation in the UV-C at 254 nm in a coating having thickness d = 53 nm. See PressRelease and Paper

 Disinfection of Smartphones


 Smartphones are commonplace all over the world. Unfortunately, the touchscreens provide a natural way to transmit infectious viruses acquired in touching public surfaces . Similarly, computers in public libraries allow viruses to be transmitted between people through the fingers. In Hong Kong, computer keyboards in public libraries are disinfected 4 times a day because of the long standing fear of the SARS and H1N1 viruses as shown below.


However, if only you use your Smartphone, you're probably pretty safe from the spread of viruses from others. But as soon as you touch public surfaces such as hand rails and poles in Public Transportation trains and buses, viruses start accumulating on your phone’s touch screen that can make you ill. Periodic cleaning would remove the pathogens, but can damage your phone.  But bacteria like clostridium difficile (which can cause diarrhea or even inflammation of the colon) and flu viruses may require a sterilizing agent like bleach or alcohol, but this is not done for fear of damaging the touch screen. 

Recently, disinfecting Smartphones with soap or bleach is claimed to br replaced avoid erseded by the PhoneSoap Charger using UV-C lamps. The phone is placed in a compartment (153 mm x 95 mm x 20 mm) for about 4 minutes. Heat, liquids, and chemicals that can damage the phone are not used. Of note, UV-C lamps and not LEDs are used in the PhoneSoap Charger.

Currently, LED’s in the UV-C are limited to EQE of a few percent [4] and not expected to impact the disinfection market until 2017/2018. EQE stands for external quantum efficiency. LEDs are used to produce UV-A and –B, but the disinfection capability is reduced compared to UV-.C. Longer exposure times are required to reach the dosage necessary for disinfection.

QED induced EM radiation emitted from the touch screen of Smartphones from body heat or that dissipated by the electronics itself is proposed to provide the UV-C from which infectious viruses may promptly be disinfected. Instead of the 4 minutes required for PhoneSoap Charger disinfection, QED disinfection only takes a few seconds.  QED stands for quantum electrodynamics, EM for electromagnetic, and UV-C for ultraviolet radiation at 254 nm. Phone touch screens would be provided with a permanent 50-60 nm ZnO coating that can be periodically cleaned to minimize pathogen residue. The UV-C from typical Smartphones provided with a nano-coated touch screen is depicted in the above figure.

The ZnO nano-coated touchscreen is similar to the recently proposed QED induced disinfection of viruses from handrails and grab poles in Public Transportation train cars and buses in Hong Kong.
 
QED induced Smartphone disinfection produces UV-C as the body heat of the hand holding the underside of the phone including the Joule heat dissipated in the phone electronics is transferred to the nano-coated ZnO touchscreen. Because of QM, the body and electronic heat cannot increase the temperature of the coating as its heat capacity vanishes under TIR confinement. QM stands for quantum mechanics and TIR for total internal reflection. Instead, the heat is conserved by QED inducing its conversion to EM radiation which can be tuned to the UV-C by proper selection of the coating thickness. See PressRelease and Paper

In conclusion, QED induced UV-C radiation from body and electronics heat offers the advantage of continuous disinfection of diseases from being transmitted by touchscreens of Smartphones.  No additional heat is necessary.

The much publicized superiority of LEDs in the UV-A and B over conventional lamps is not yet proven for UV-C disinfection. Even if UV-C LEDs are developed, QED induced UV-C disinfection is far simpler as a ZnO nano-coating positioned near the pathogen only needs to be driven by body heat and at most small mW electrical heaters.

In Public Transportation train cars and buses, Smartphones are used by almost all passengers all the time. What this means is passengers themselves may use QED induced UV-C from their Smartphones to disinfect viruses they acquire upon touching hand rails and poles, as they must to avoid falling during sudden train and bus motions. 

 QED Induced Water Purification

Currently, WHO/UNICEF estimates almost 1 billion people in the developing world do not have access to safe drinking water. Moreover, about 2 million childhood deaths have been attributed to water-borne diseases. Conventional water treatment is unfeasible because of costs. Lacking municipal water supplies, the water is collected from rivers or lakes and stored in containers for later use which may also be contaminated. The most direct way of purification  is by boiling small quantities of water, but this requires a source of heat which, except for fire, is usually not available. Because it is not always convenient to build a fire, it is highly desirable to consider alternative low-cost methods for purifying water.

Unfortunately, there are no known low-cost alternatives to purifying water other than by boiling. However boiling has disadvantages because a source of heat is needed. One could envision focusing sunlight to boil small volumes of drinking water, but the purified water would only be available during daylight hours. If, however, portable electrical power is available, the water could be pumped through ceramic or resin filters coated with silver NPs. NP stands for nanoparticle. Silver NPs are widely known to provide antimicrobial action by damaging the DNA of bacteria, but NPs that come off the filter and enter drinking water also damage human DNA, that if not repaired, may lead to cancer. Regardless, NP coated filters are unfeasible because electrical pumping power is usually not available. In contrast, UV disinfection of drinking water occurs outside the body and avoids the danger of cancer posed by silver NPs, but is unfeasible as electrical power is generally not available and costly even if available.

The developing world needs an inexpensive way of purifying drinking water.

QED induced UV radiation using nano-coated drinking bowls is proposed as the mechanism by which drinking water is purified inexpensively without electrical power. QED stands for quantum electrodynamics. QED induced purification is a consequence of QM that forbids the atoms in nano-coatings under TIR confinement to have the heat capacity to increase in temperature. QM stands for quantum mechanics and TIR for total internal reflection.

Disinfection occurs as the body heat from the hands of the person holding the drinking bowl is transferred to the coating as shown in the above figure. Because of QM, the body heat cannot increase the temperature of the coating as its heat capacity vanishes under TIR. Instead, the heat is conserved by QED inducing the heat to be converted to EM radiation. EM stands for electromagnetic. The TIR confinement only occurs as heat flows into the coating, i.e., absent body heat there is no TIR confinement and UV radiation. The TIR wavelength λ of the EM radiation is,

λ = 2 n d

where, n and d are the refractive index and thickness of the coating. Since the optimum UV wavelength range to destroy bacteria is between 250 and 270 nm, a zinc oxide coating having n = 2 requires the coating thickness d = 65 nm. Since human body heat is about 6 mW / cm2, and since UV water disinfection requires an intensity of 16 - 38 mJ / cm2, the drinking  bowl disnifects water in 3 to 6 seconds. See Press Release. , Paper and Presentation

On November 6, the IUVA held a one-day symposium on the UV disinfection of water in the developing world at UNESCO-IHE in Delph, Netherlands.  See Advertisement New developments in UV sterilization of water proposed LED sources as a replacement for mercury discharge. However, the water bowl UV disnfection of water is far more efficient than LEDs as no electrical power is required. Funding of water bowl research was discussed with attendees.



N-V Thermometry in LIving Cells

The October issue of Physics Today reported electron-spin measurements at N-V defects in diamond allows resolution of temperatures from 300 to 650 K at mK accuracy. N-V stands for nitrogen-vacancy as shown in the above figure.  But the supporting experiiments for were based on bulk mm-scale diamond crystals – not NDs.  ND stands for rnanodiamond. Hence, N-V spin level thermometry in mm-scale diamond crystals is indeed feasible in temperature measurements at the macroscale, but thhe crystals are too large to measure temperatures inside living cells having dimensions of a few 10's of microns.  Instead, NDs of 100 nm size implanted in living cells are proposed to measure cell temperatures.
 
Unlike the bulk mm-scale diamond, QM denies the atoms in NDs the heat capacity to allow temperature changes to occur thereby refuting the claim that ND temperature can be measured from thermal strains in mm-scale diamond samples. QM stands for quantum mechanics. Thermal strains in NDs are therefore not the same as in the mm-scale crystals making  the HD thermometry of living cells highly questionable.  
 
QED induced EM radiation is proposed as the mechanism by which the local thermal energy of the living cell is conserved in NDs without temperature changes. QED stands for quantum electrodynamics and EM for electromagnetic. QED induced radiation is a consequence of QM that denies the atoms in NDs under TIR confinement to have the heat capacity to allow changes in temperature. TIR stands for total internal reflection. 
 
Indeed, classical heat transfer of NDs shows uniform temperatures throughout that almost spontaneously follow the local cell temperature. QM differs. Since the ND temperatures cannot change by QM, the local thermal energy acquired from the cell may only be conserved by QED creating EM radiation in the ND having Planck energy E = hf, where h and f are Planck’s constant and the TIR frequency of the ND. Since NDs have high surface to volume ratios, almost all of the local thermal cell energy acquired by the ND directly excites its TIR mode. In effect, TIR confines the acquired cell energy to the ND surface having a wavelength given by its circumference.
 
But how then may the ND infer local temperature in the living cell?
 
By QM, local cell temperatures are inferred by N-V spin-flips from thermal strains induced in the ND as only the temperature of the surface changes. Atoms in the interior of the ND do not increase in temperature, but the surface atoms do indeed follow the cell temperature. Unlike uniform thermal expansion predicted by classical physics, expansion of the ND surface  strains the interior N-V centers. Diamond noted for sensitivity to strain is therefore correlated by QM to the local cell temperature, the correlation of which cannot be deduced from the uniform ND temperatures predicted by classical physics.See PressRelease     .   

The Conclusions are;
Classical physics by assuming the atoms in NDs have heat capacity predicts uniform ND temperatures equal to the local cell temperature cannot induce the thermal strain at interior N-V centers required by QM, and
QM by negating the heat capacity of the atoms in NDs precludes temperatures within the ND from following local cell temperature. But QM by confining temperature changes to the ND surface induces strain at interior N-V centers to allow correlation of optical transitions with local cell temperature, and
The ND measurement of temperatures in living cells based on the spin-flip optical transitions n mm-scale diamond crystals is questionable, and
Although QM allows NDs to measure cell temperatures, the toxicity of the EM radiation at UV frequencies emitted from the NDs is likely to damage DNA within the cell and should be considered in cell temperature measurements.  

Holy Grail of Catalysis 

 Since the 1980's, the oxidative catalysis of natural gas or methane to ethylene, aromatics, and hydrogen including propylene, benzene, toluene, and naphthalene has required oxygen at high temperatures > 1073 K. Beyond the low 50% carbon utilization efficiency, oxygen leads to the over oxidation product of CO2 which is not environmentally friendly. Today, many catalysts to avoid the oxidative conversion of natural gas have been proposed, but none are yet economically available.

Indeed, catalysts have long been considered the Holy Grail of chemistry. In the conversion of methane gas to ethylene, the Holy Grail is a catalyst that can activate the first C–H bond of methane without oxidation. But it is very challenging, if not impossible for any catalyst as 4.35 eV  is required to cleave the C-H bond while methyl radicals at 9.84 eV only form at the 12.6 eV ionization potential of methane.

Recently, Science contrary to the requirement of 12.6 eV ionization potential  reported the direct nonoxidative conversion of methane at the relatively high efficiency of  50% at 1363 K. The catalytic mechanism thought to explain the remarkable methane conversion efficiency without the formation of CO2 was based on passing the methane over a surface comprising single iron sites embedded in a silica matrix, the iron sites being 2-5 nm nanoparticles. Nanoconfinement of the iron sites in the silica surface was thought to initiate the catalytic generation of methyl radicals, followed by a series of gas-phase reactions.

Experimentally, the methyl radicals including the aforementioned methane reaction products were clearly observed with ultraviolet spectroscopy, Ibid.  Theoretical support of the series of gas-phase reactions at 1225 K was simulated with DFT by assuming the nanoconfinement mechanism somehow formed a pair of methyl radicals at 9.84 eV. DFT stands for density functional theory. The DFT simulation showed the methyl radical pair to combine in a strongly exothermic process to produce ethylene, but otherwise leads to all of the methane reaction products.

The problem is the DFT simulation may explain how methyl radicals once formed combine to produce the methane reaction products, but does not explain how the nanoconfnement mechanism of iron sites in the silica surface produces the 9.84 eV necessary to form the methyl radicals. A catalytic mechanism capable of ionizing the methane molecule at 12.6 eV is required.

QED induced radiation is proposed as the catalytic mechanism capable of ionizing the methane molecule. QED stands for quantum electrodynamics. Finding basis in the QM requirement that the heat capacity of the atoms in the iron sites vanishes at the nanoscale, heat absorbed by the iron site from the silica matrix cannot be conserved by an increase in temperature. QM stands for quantum mechanics. Instead, conservation proceeds by the QED induced frequency up-conversion of the absorbed heat by the iron site to non-thermal EM radiation at its TIR confinement frequency. EM stands for electromagnetic and TIR for total internal reflection. QED induced catalysis by nanoparticles is not new. See ChinCatalysis   Indeed, the EM radiation having Planck energy beyond the UV is sufficient to ionize methane molecules that come near the iron site. See numerous QED applications on this web page.   

However, the QED induced catalytic conversion of methane by iron sites in a silica matrix may be significantly enhanced by flowing the methane through a cylindrical reactor provided with a removable liner comprising a nanoscale iron coating on a silica substrate, the substrate having a thickness of a few 10s of microns as shown the thumbnail. The liner may be formed by rolling-up a flat geometry where it is more convenient to control the nano coating thickness. A surface heater supplies the heat Q to the nanoscale iron coating, but by QM the nano coating cannot increase in temperature. In are:stead, QED induces the heat to be converted to EM radiation that ionizes the methane to produce the methyl radicals that initiate the formation of ethylene. See   PressRelease   .

Conclusions are:

1. The catalytic nature of nanoparticles by QED induced radiation is not new. The QM restriction of vanishing heat capacity of atoms in nanoparticles requires the conservation of any form of absorbed EM energy by the emission of QED radiation that enhances chemical reactions.   .

2. QED induced radiation based on QM having the capability of ionizing natural gas explains the remarkable efficiency in catalytic surfaces comprising iron nanoparticles in a silica matrix is indeed the Holy Grail of catalysis..

3. By QED radiation, conversion efficiency may be significantly improved by flowing natural gas through a cylindrical reactor provided with a removable liner comprising a nanoscale iron coating on a silica substrate, although other more suitable materials may be used. The QED radiation wavelength depending on the thickness of the nano coating may be tailored to excite the desired quantum state of the flowing gas molecules simply by providing a set of liners with differing nano coating thicknesses. 

 QED Disinfection of China's Water

China’s massive population poses difficult environmental challenges for a nation of some 1.2 billion people. Indeed, water pollution and waste management are among the most pressing issues. Over 3.5 million tons of sewage waste per day requires extensive treatment facilities. Perhaps half of all Chinese — 600 million people—drink water that is contaminated by human waste are subjected to waterborne pathogens and a myriad of human health concerns.

But contaminated drinking water is not unique to China. WHO/UNICEF estimates almost 1 billion people do not have access to safe drinking water. Although visitors to China generally do not stay long to expose themselves to health risks from heavy metals, they almost all will meet "La Dudza" - the Chinese version of diarrhea within their first days after arrival.

The WHO estimates that 64% of all premature deaths in China are related to water-borne toxins consumed on a regular basis by a majority of the nation's population that cannot afford bottled water, and even if bottled water is available the consumer at the point of use never knows if it is indeed safe. The most direct disinfection is by boiling at the point of use, but except for water boiling units in restaurants is not available to the individual consumer.

Unfortunately, there are no known low-cost alternatives to purifying water for the individual other than by boiling. Even if tap water becomes drinkable, few people will stop boiling drinking water, a habit that is ubiquitous in China. Alternative water disinfection is desirable.

Currently, LEDs in the UV-C are thought to provide the individual with point of use disinfection of drinking water, but still require a source of electrical power. LEDs stand for light emitting diodes. However, LED’s in the UV-C are limited to EQE of a few percent and not expected to impact the disinfection market until 2017/2018. EQE stands for external quantum efficiency.  In contrast, the QED drinking bowl has 100% efficiency, but is limited by low body heat. .

QED induced disinfection of drinking water is a consequence of QM that precludes the atoms in nano-coatings to have the heat capacity to conserve body heat by an increase in temperature. Instead, the heat is induced by QED to produce UV radiation. The US HEW set guidelines for UV light disinfection to require a minimum dose of 16 mJ / cm2 at all points throughout the water disinfection unit, but recently the National Sanitation Foundation International set the minimum UV light requirement at 38 mJ / cm2 for treat visually clear water.

Currently, QED induced disinfection of drinking water is currently under development. Prototypes comprise a 1 mm thick half-sphere aluminum bowls (100 mm diameter x 50 mm high) that fit into the palm of one hand as shownin the above figure. Melamine and glass bowls were considered, but have a low thermal conductivity compared to aluminum which is important to take advantage of the 12 C differential between body temperature (32 C) and ambient (20 C). Moreover, melamine and glass are fragile compared to the ductility of aluminum to avoid fracture upon accidental dropping. According to QED theory, a 53 nm ZnO nano-coating consistent having a refractive index of 2.4 therefore converts 100% of body heat 5.71 mW / cm2  to UV-C. See  Paper


The Ebowla in disinfecting the Ebola virus



The Ebola virus outbreak is a worldwide concern.  the CDC has issued guidelines for how Ebola is to be disinfected in hospital and healthcare centers. CDC stands for Center for Disease Control. Currently, robotic UVGI systems are proposed to decontaminate healthcare facilities. UVGI stands for Ultraviolet Germicidal Irradiant. Hospital staff controls the robot, but vacate the room during the application of UVGI light pulses that continue for 5 minutes.  Greater flexibility is provided with hand-held UVGI systems that allow mobile and rapid disinfection of Ebola on surfaces and the surrounding air. Electrically powered 400 W hand-held devices producing a blade-like UV-C light beam (50 mm wide x 500 mm high) achieves 99% reduction of the Ebola virus in 5 seconds. Large areas are decontaminated using slow scanning of the UV-C light beam.
 
The UVGI systems disinfect Ebola including Tuberculosis and Lassa by irradiating surfaces and air using 254 nm UV-C light. But UV-C disinfection may be used for other pathogens, e.g., the CDC states that “about 1 in 20 patients have an infection while receiving health care treatment in U.S. hospitals.” Disinfecting health care facilities of all pathogens is challenging scientists to develop more advanced technology for better disinfection.
 
However, the recent Ebola outbreak in West Africa highlights the inability of countries in the developing world to control the spread of the Ebola virus. Indeed, the protocol for Ebola disinfection available in the U.S. is too complex and costly. Simply put, lack of money has hampered healthcare facilities and personnel from controlling the spread of the Ebola virus. In the developing world, robotic and manually operated UVGI systems in the U.S. are simply too costly let alone requiring sources of electricity which are usually not available.
 
QED induced EM radiation from body heat in hand-held nano-coated bowls called Ebowlas is proposed to provide the UV-C from which the Ebola virus on surfaces or in the air may be disinfected inexpensively without electrical power. QED stands for quantum electrodynamics and EM for electromagnetic. The 80 mm diameter Ebowla forms a cylindrical beam of UV-C light for disinfection. The Protocol is to scan holding the Ebowla in one hand, the details of which are shown in the figure above. In principle, the Ebowla is similar to the recently disclosed hand-held water bowl that uses body heat to kill water borne pathogens in drinking water without See QED induced water purification above

The QED induced UV-C radiation from the Ebowla is especially suited for disinfecting the Ebola virus in the developing world that lacks sources of electricity. Costs are minimal allowing the Ebowla to be distributed to individuals by governments without costs. Moreover, the Ebowla may also be used to disinfect drinking water. But even in the U.S. and the developed world, the Ebowla would allow simple germicidal disinfection for nurses in hospitals or the public in their homes as well as assuring drinking water is free of pathogens. Where drinking water disinfection is not so important, the Ebowla may be replaced with a flat nano-coated surfaces, say carried in the pocket of a nurse or worn as a badge.
 
Ebola disinfection by QED induced UV-C from body heat using hand-held Ebowlas is new, but not the use of body heat to power electronics. Recently, body heat in holding a flashlight was shown to produce light. Peltier cells were built into the flashlight's casing to absorb body heat from a person's hand. Although QED induced radiation is far more efficient than the Peltier effect, only monochromatic light for a given coating thickness is produced. Therefore, using QED to make, say red flashlights is possible, but not white light comprising a mix of frequencies. Whether the nano-coating thickness can be structured to produce QED induced white light remains to shown.

Funding of QED Induced Disinfection Research


The 3rd International Conference on Prevention & Infection Control (ICPIC), to be held fin Geneva rom 16 to 19 June 2015. ICPIC provides a unique forum for the exchange of knowledge and experience in the prevention of healthcare-associated infection and control of antimicrobial resistance around the world. Though advances in infection control and prevention are being made, antimicrobial resistance persists as a global threat confronting all countries alike.

Of particular ICPIC interest is the recent disinfection of the Ebola virus in West Africa including the long-standing problem of the disinfection of water borne pathogens in drinking water common throughout the world, especially in China and India.

In this regard, QED induced disinfection is proposed to provide people in the developing world with a means to disinfect both the Ebola virus and drinking water themselves using UV-C radiation from hand-held nano-coated bowls powered only by body heat. Electricity or batteries are not required.

At first, the notion of QED disinfection of the Ebola virus and water borne pathogens from drinking water using body heat without electricity may appear absurd, as we normally think adding heat to anything causes its temperature to increase. But Einstein once said:

“If at first, the idea is not absurd, then there is no hope for it. Innovation is not the product of logical thought, although the result is tied to logical structure.”

The ICPIC Innovation Academy allows investigators to participate in a forum which brings together innovations in the practice of infection control. Innovation stems from Latin - innovatus - which requires a new way of applying discovery. Unlike classical physics, QED disinfection is based on quantum mechanics that precludes body heat from being conserved by increasing the temperature in nanoscale coatings because the heat capacity of the atom vanishes. In contrast, classical physics allows the temperature to increase in nanoscale coatings as the atom is erroneously assumed to always have heat capacity. By quantum mechanics,  conservation of body heat proceeds by the emission of non-thermal EM radiation. Proper selection of the nanocoating material and thickness allows the EM emission to be tuned to the UV-C where almost all infectious viruses may be disinfected. See ICPIC Abstract and Presentation 

Exoplanets placed in question by cosmic dust


The discovery of exoplanets orbiting the distant star HR8799 supports the theory that exoplanets surround other stars in the Universe consistent with the planets that orbit our sun. See AJ paper. But the HR8799 System differs from our solar system as HR8799  is:  (1)  a young star containing large amounts of dust haloes not present in our solar system, and (2) emits UV radiation 3 orders of magnitude higher than our sun. But dust is a problem because even in the interstellar medium, far smaller quantities of dust affect all astronomical measurements of redshift, e.g., the Hubble redshift in an expanding Universe central to cosmology. In fact, dust requires requires corrections to measured Z to determine Hubble Z using the difference between the redshift of Lyman-alpha and H-alpha lines.
 
                             Zcorrection =  (Z Lyman-alpha -Z H-alpha)
                                   ZHubble = Zmeas - Zcorrection
 
If Z correction = 0, Z Hubble = Zmeas. But if Zcorrection > 0, ZHubble < Zmeas. Details are given in APRIM 2014 “Cosmology and Cosmic Dust,” 2014. For convenience, the APRIM paper may be opened here.  
 
Extensions of redshift by dust between a receding galaxy and the Earth may be made to the effect of dust in the measurement of IR spectra from the location of a perceived exoplanet and the star by assuming all the redshift occurs in the dust. However, the question is:   
 
Whether the dust debris of distant solar systems confounds IR spectra measurements to question the claimed discovery of exoplanets?
 
In the HR8799 system, four planets were claimed discovered based on IR spectroscopic measurements in the wavelength range from 995 to 1769 nm.  Molecular lines of common gases found in the atmospheres of planets in our solar system were used including ammonia, acetylene, methane, and carbon dioxide. However, the IR spectra of HR8799  showed anomalies that suggest the spectra are not produced by molecules on the planets. What this means is the IR spectra taken as proof of the discovery of the exoplanets is questionable. For details, see PressRelease
 
Briefly,  the IR spectra of HR8799 are not produced by molecular lines of common gases, but rather ny the QED induced redshift of UV radiation (Lyman-alpha) photons in dust NPs the of debris haloes. QED stands for quantum electrodynamics and NPs for nanoparticles. The consequence of QED radiation is the molecules thought measured by IR spectroscopy are in fact redshifted Lyman-alpha photons having a wavelength depending on the size distribution of the dust NPs between the perceived location of the planet and HR8799.  
 
What this means is exoplanets orbiting a distant star may exist, but any discovery cannot be proven using the IR spectra of common planetary gases. Young stars like HR8799 emit Lyman-alpha radiation that is absorbed in dust NPs of debris disks to produce IR spectra that could falsely be interpreted as proof of an exoplanet discovery - when in fact the IR spectra is an artifact of dust and the exoplanet does not exist.

Expanding Universe or Cosmic Dust?

Recently, Physics Today reported AME in BICEP2 measurements at 150 GHz supported the presence of gravitational waves formed in the rapid expansion following the Big Bang. See Article Gravitational waves are thought to place the CMB in a conditon of B-mode polarization. AME stands for Anomalous Microwave Emission and CMB for Cosmic Microwave Background. However, cosmic dust in the Milky Way may also produce AME similar to that found in BICEP2 thereby placing in question the Big Bang and the expanding Universe. See Paper Later, extrapolation of 353 GHz Planck telescope data to 160 GHz suggested the AME was caused by dust and not remnants of gravitational waves, thereby placing doubt in the expanding Universe. See Planck Paper 
 
QED induced EM radiation in cosmic dust NPs is proposed as the mechanism by which both AME and Hubble redshift may be used to asess an expanding Universe. QED radiation is a consequence of QM that denies the atoms in NPs under TIR confinement to have the heat capacity to allow increases in NP temperature upon absorbing galaxy light.
 
In AME and Hubble redshift, the only galaxy light considered is single Lyα photons absorbed in spherical dust NPs of amorphous silicon. Ly stands for Lyman. Since NPs have high surface to volume ratios, the absorbed Lyα photon is induced by QED to be totally confined by TIR to the NP surface. Hence, the TIR wavelength of the QED induced photon is the NP circumference 2π a n, where a and n are the NP radius and refractive index. See Korean Paper However, the QED response of the NP to AME produced by the Lyα photon depends on its size, the maximum diameter 2a < 1 micron. In small NPs with a < 0.04 micron, the Lyα photon is conserved by spinning the NP, the dipole moments of which producing the AME; whereas, the larger NPs having a > 0.04 micron redshift the Lyα photon to produce VIS and near IR light. The AME frequency and Hubble redshift wavelengths in relation to the dust radius in the figure above.
 
In QED redshift, NPs for a > 0.040 microns absorb single Lyα photons, i.e., blueshift requiring greater EM energy than that of the Lya photon cannot occur as the conservation of energy would be violated. The QED induced redshift Z in dust is, Z = ( λ - λ* ) / λ*, where λ and λ* are the wavelengths of the QED redshifted and Lyα photons. For a < 0.5 microns, the figure shows the redshifted wavelength 0.376 microns begins at NP radius a = 0.04 microns in the VIS to 5.7 microns in the IR. Larger NPs > 1 micron are required to produce QED induced UIR bands, but heating of NPs and PAH to produce IR emissions is precluded by QM. UIR stands for unidentified infrared and PAH for polycyclic aromatic hydrocarbons.
 
With regard to AME based on classical physics, the absorbed Lya photon is dissipated by an increase in temperature, see e.g.  Paper  But temperature increases are forbidden by QM. Hence, the absorbed Lyα photon can only be conserved in the TIR mode of the NP. Since blueshift cannot occur, and since the TIR mode is tangential to the surface of the NP, the Lyα photon naturally produces circularly polarized light around the NP to exert a torqueon the NP. Hence, the the Lyα photon energy is conserved by the kinetic energy of spinning NP.  Circularly polarized light in NPs is illustrated below by the E-field rotating normal to the NP surface upon Lyα photon absorption.

QED induced AME conserves the Lyα energy hc / λ* with rotational energy ½ J ω2 of the NP giving the spin rate ω = √(2 h c / J λ*), where h is Planck’s constant, c the speed of light, J the NP rotational moment of inertia, J = 2 ma2/ 5, and m the NP mass. For amorphous silica having density 2650 kg / m3, the figurel shows the spin rate ω over NP radii 0.001 < a < 0.04 microns corresponds to AME from 0.1 to 860 GHz.
 
In summary, current AME mechanisms that excite NP rotation by IR emission from increased temperatures upon UV absorption cannot be valid by QM. Similarly, the UIR bands thought formed by increased temperatures of PAH molecules are not valid.
 
Further, the AME is most likely caused by dust – not as a relic of gravitational waves in an expanding Universe following the Big Bang. The CMB spectrum therefore can only be caused by thermal blackbody radiation from a static Universe reaching an equilibrium temperature of 2.726 K over an infinitely long time.

 Covetics by QED Radiation



Covetics are new compounds formed by adding carbon NPs to molten metals (aluminum, copper, silver, etc.) that upon solidification enhance the yield strength– of the metal. See Covetics overview.

However, controversy surrounds how the Covetics bond forms with the metal. During thermal processing of Covetics, a known amount of carbon is added to the molten metal. Upon solidification, Covetics samples are taken from which the carbon bonded to the metal is thought given by the difference between the carbon added and that combusted by the LECO method. In LECO, a sample is heated in oxygen to 1500 C and the carbon content inferred from the CO2 produced by the chemical reaction with oxygen by infrared absorption spectrometry.

But the bonding of carbon NPs to aluminum is questionable as the Covetics is observed to not change contrary to the law of mixtures that predicts ~10 % reduction in density. See above micrograph of carbon NPs in fracture surface of 6061 aluminum. A similar problem on density was found for copper. Moreover, the activation energy for the formation of the Covetics bond based on DFT has failed to show stable carbon-metal configurations. DFT stands for density functional theory. Both the law of mixtures and DFT suggest bonding of carbon to the metal lattice cannot be the Covetics mechanism.
 
For details, see Paper and Press Release  
 
Conclusions are:

 1. Covetics by QED radiation depends on whether the carbons added to the melt are nano or microcarbons. In Al Covetics, adding NPs at ambient temperature enhances the yield strength by QED stiffening of the lattice, but NPs remain in the lattice. See QED stiffening of silver nanorods.

But in Cu Covetics, micron sized particles of  activated carbon acquire the melt temperature and by combustion reduce in size to  become NPs. But unlike Al NPs added at ambient temperature, Cu NPs at melt temperatures promply combust. Absent NPs, there is no enhanced yield of the Cu Covetic by QED stiffening. For microcarbons, only carbon bonding may enhance the yield. Regardless, tensile tests are required to support claims of yield enhancement in Covetics
 
2. The failure of DFT to find stable metal-carbon atomic binding configurations and the lower density expected from the law of mixtures is consistent with the missing carbon inferred from LECO being combusted in thermal processing compared to the less favorable formation of carbon bonding to the metal lattice.  
 
3. Covetic nanoscale films do not show NPs as the microcarbons are most likely toyallly combusted in thermal processing. 


Cancer Risk: Worse than bad luck?

Science reported genomic changes occur in an organ simply by chance during DNA replication rather than as traditionally thought by carcinogens. Paper  The study showed that although melanocytes and basal epidermal cells of the skin are both exposed to the same dose of UV from solar radiation, melanomas are much less common than basal cell carcinomas because the larger number of basal epidermal cells undergo a higher number of divisions than melanocytes.
 
However, not all agreed. The contrarian argument may be made that cancer need not be proportional to the number of replications that the DNA undergoes, but by carcinogens that damage the DNA independent of replications.  
 
But cancer riusk by chance is not necessary as there is a causal explanation:
 
Melanosomes that form in the melanocytes contain melanin granule NPs that emit UV radiation causing DNA damage that leads to mostly basal cell carcinomas with  few melanomas. NPs stands for nanoparticles.
 
Indeed, it widely known the antimicrobial action of NPs is caused by damaging the DNA of bacteria, but by the same reason NPs also damage human DNA, that if not repaired, may lead to cancer. The human body naturally creates NPs that may damage the DNA, e.g., the breakdown of epithelial tissue which produces NPs associated with the spread of tumors.
 
With melanin NPs, the cancer risk byUV radiation is depicted in the figure. Melanocyte cells located in the basal layer of the dermis have dendrite structures that penetrate into the lower epidermis. Melanosones having sizes of about 1 micron formed within the melanocytes pass through the outer tips of the dendrites into the dermis. Removed from melanocytes, the melanosomes are collections of < 100 nm melanin granule NPs.  
 
By  QED induced EM radiation, the melanin NPs absorbing heat from the thermal surroundings cannot increase in temperature because of quantum mechanics. Provided the refractive index of the NP is greater than that of the cellular surroundings, the heat is conserved by QED inducing the melanin NPs to emit UV radiation, a condition that is satisfied for 30 nm melanin NPs having an index of 1.7 while that of the surroundings is 1.35. Paper In this way, the emission of UV radiation from the melanin NPs damages the DNA in both melanocytes and basal cells. But because of the small number of melanocytes in the basal layer, most DNA damage caused by the UV radiation from the melanin NPs occurs in the basal cells with little, if any DNA damage in the melanocytes. Basal cell carcinoma is therefore far more common than melanoma.
 
Cancer risk may not be a matter of chance or bad luck. Rather, cancer may be caused solely by DNA damage from QED induced UV radiation in NPs. Setting aside DNA damage by chemicals, the hypothesis may be made that UV radiation from melanin NPs in melanocytes is the sole cause of cancers because of the DNA damage in surrounding tissue. But the NPs need not be limited to melanin - all biological and man-made NPs damage the DNA, e.g., the nicotine NPs that enter lung tissue by smoking. A literature review of cancer risk based on the presence of < 100 nm NPs in all cancers is required to further assess  this hypothesis.

The Static  Universe by Quantum Theory




Man knows life has a beginning and an end, and it is only natural to think the Universe also has a beginning and an end. Yet, for thousands of years, the Universe was considered static and infinite - without a beginning and end. However, Einstein in 1916 introduced his field equations that required the Universe to be finite and either contracting or expanding. Since a static Universe is foreign to human experience, Einstein provided a theoretical basis to suggest the Universe is not static, but rather began with the Big Bang. Lacking experimental proof, Big Bang theory lay dormant until 1929 when Hubble dismissed a static Universe by showing the light from distant galaxies was redshift. Interpreted by the Doppler Effect, the Hubble redshift was taken as proof the Universe is expanding ever since the Big Bang.

However, Big Bang theory was recently questioned by replacing classical geodesics with quantum trajectories. Quantum-corrected Friedmann equations derived within the context of general relativity showed the singularity of the Big Bang does not exist. The quantum corrections can be thought of as a cosmological constant term without the need for dark matter and energy. The Universe is assumed filled with gravitons — hypothetical massless particles that mediate the force of gravity,  but if gravitons do exist have been shown to form a Bose-Einstein condensate at any Universe temperature, otherwise thought to require the high temperatures of the Big Bang.

Quantum trajectory theory like the Big Bang is a still a theory. Experiments are required to show the existence of the graviton, but like the Higgs boson in Big Bang theory, the existence of the graviton has not been verified. Regardless, quantum trajectory theory lacking dark matter and energy leading to a static Universe is contradicted by Hubble redshift based on the Doppler Effect that shows the Universe is expanding.

What this means is Quantum theory can only be valid if Hubble redshift is replaced by a non-Doppler redshift that may be verified by experiment    

QED induced redshift in cosmic dust NPs is proposed as the non-Doppler redshift to replace Hubble redshift by which the Quantum theory may avoid dark matter and energy consistent with a static Universe. QED stands for quantum electrodynamics and NPs for nanoparticles. But this does not mean the Universe is expanding as QED redshift by replacing Hubble redshift also leads to a static Universe. Unlike Quantum and Big Bang theories, QED redshift of galaxy light in NPs may readily be confirmed in laboratory experiments.

QED redshift is a consequence of QM that denies the atoms in NPs under TIR confinement the heat capacity to allow changes in temperature upon absorbing galaxy light. QM stands for quantum mechanics and TIR for total internal reflection. An expanding Universe has been questioned because of cosmic dust exaggerating Hubble redshift measurements of distant galaxies by the Doppler Effect. See Press Release

Today, astronomy relies on classical heat transfer to explain how NPs absorbing single galaxy photons increase in temperature to produce the observed IR spectra in the Universe. But QM differs. Since the NP temperatures cannot change by QM, the absorbed galaxy photon may only be conserved by QED creating a redshift photon inside the NP having Planck energy E = hf, where h and f are Planck’s constant and the TIR frequency of the NP. Since NPs have high surface to volume ratios, almost all of the galaxy photon energy directly excites its TIR mode. In effect, TIR confines the absorbed energy to the ND surface having wavelength given by its circumference, i.e., the TIR frequency f = c / λ , where c is the velocity of light and  λ = 2Π a n. Here, n and a are the refractive index and radius of the NP. What this means is QM requires the galaxy photon to be conserved without an increase in NP temperature by the creation of QED radiation at the TIR frequency f of the NP that is then emitted as a redshift photon. See Paper
 
In conclusion, Big Bang theory relies on Hubble redshift of galaxy light by the Doppler Effect as proof of Universe expansion, but requires verification of the Higgs boson or the presence of dark matter and energy.

Quantum theory based on trajectories instead of classical geodesics mediated by gravitons leads to a static Universe without the need for dark matter and energy, but Hubble redshift is required to be replaced by QED redshift in cosmic dust.

But if QED redshift in dust replaces Hubble redshift, the expanding Universe of Big Bang theory like Quantum theory leads to a static Universe  

Unlike Big Bang and Quantum theories, QED redshift in cosmic dust is readily verified by experiment. Hence, QED redshift in cosmic dust proves the Universe is static and clearly not expanding
