Water and carbon dioxide (CO2) can be converted into ‘solar thermochemical fuel’ using energy from the sun and very high temperatures. A new study has analysed the production of this fuel and found that, under favourable future conditions, costs could be as little as €1.28 per litre, with close to zero life-cycle greenhouse gas (GHG) emissions. Although suitable as a substitute for any hydrocarbon fuel, it could be particularly useful as a much-needed alternative for energy-dense jet fuel.

Titanium dioxide nanoparticles are entering the environment in ever greater quantities as a result of their widespread use in consumer products and as a disinfectant of sewage. Researchers have recently discovered that titanium dioxide nanoparticles have a toxic effect on marine phytoplankton when exposed to normal levels of ultraviolet light found in natural sunlight.

The heat from the sun heats up metal oxides that in turn release oxygen atoms that mingle with steam. Hydrogen molecules can then be captured and stored.

Researchers found that rooms exposed to sunlight kept the germ population in check better than rooms that received no sunlight at all.

(Kobe University) Hydrogen is a possible next generation energy solution, and it can be produced from sunlight and water using photocatalysts. A research group from Kobe University has developed a strategy that greatly increases the amount of hydrogen produced using hematite photocatalysts. In addition to boosting the high efficiency of what is thought to be the world's highest performing photoanode, this strategy will be applied to artificial photosynthesis and solar water-splitting technologies via university-industry collaborations.

Phototherapy effectively treats unconjugated hyperbilirubinemia. However, in resource-poor settings, functional phototherapy devices are often unavailable due to financial constraints or erratic electrical power availability.

Filtered-sunlight phototherapy could be a cost-effective option in resource-poor settings with abundant sunlight. (Read the full article)

Sunlight kills COVID-19 while warmer temperatures and humid weather significantly damage the virus, measured in terms of the virus' half-life or the time it takes to cut its potency in half, according to the latest breakthrough research from the US Department of Homeland Security's most advanced biocontainment lab, released at the White House on Thursday.

The coronavirus outbreak in the US has killed nearly 50,000 Americans and infected more than 860,000 till date. Research around the effect of temperature and humidity has been gaining traction for weeks, these are the most downloaded papers on research websites but this is the first time the US government has put an official stamp on initial results of temperature tests on COVID-19.

"Our most striking observation to date is the powerful effect that solar light appears to have on killing the virus, both on surfaces and in the air. We've seen a similar effect with both temperature and humidity as well. Increasing the temperature and humidity or both is generally less favourable to the virus," Bill Bryan, chief of the science and technology directorate at the US Department of Homeland Security, said.

In a room at 70-75F temperature with 20 per cent humidity, the half-life of the virus is about an hour, according to Bryan. "But you get outside and it cuts down to a minute and a half, very significant difference when it when it gets hit with UV rays," he said.

According to the same research, the virus' half-life on surfaces reduces dramatically with a combination increase of temperature and humidity. When the temperate is kept constant at 70-75F and only the humidity is cranked up from 20 per cent to 80 per cent, the virus' half-life is shown to crash from 18 hours to 6 hours. If the temperature is increased to 95F, the half-life sinks to barely 60 minutes.

Bryan said this testing was done at DHS' advanced biocontainment lab in Maryland, just outside the national capital. Pointing to charts with data from experiments on the COVID-19 virus, Bryan said the virus half-life plunges "drastically" with exposure to higher temperatures and even minimal exposure to humidity.

Bryan said the DHS biocontainment lab is the only one in America that has the capability to do the kind of testing that has led to the research on the virus' UV and temperature tolerance.

Bryan explained the mechanics of the COVID-19 temperature tolerance experiment in simple terms. He said the virus was first locked into a 5-gallon bucket and suspended in the air inside. "We're able to take a particle of a virus and suspend it in the air inside of this drum and hit it with various temperatures, various humidity levels, multiple different kinds of environmental conditions to include sunlight. And we're able to measure the decay of that virus while it's suspended in the air. This is how we do our aerosol testing."

"While there are many unknown links in the COVID-19 transmission chain, we believe these trends can support practical decision making to lower the risks associated with the virus," Bryan said. The DHS team has also tested the effect of bleach and isopropyl alcohol on the virus, "specifically in saliva and respiratory fluids".

"And I can tell you that bleach will kill the virus in five minutes, isopropyl alcohol will kill the virus in 30 seconds, and that's with no manipulation. No rubbing."
