Catalytic process with lignin could enable 100% sustainable aviation fuel      (via sciencedaily.com) 

An underutilized natural resource could be just what the airline industry needs to curb carbon emissions. Researchers report success in using lignin as a path toward a drop-in 100% sustainable aviation fuel. Lignin makes up the rigid parts of the cell walls of plants. Other parts of plants are used for biofuels, but lignin has been largely overlooked because of the difficulties in breaking it down chemically and converting it into useful products.

Rooftop solar cells can be a boon for water conservation too      (via sciencedaily.com) 

Electricity-generating rooftop solar cells not only save on planet-warming carbon emissions, they also save a significant amount of water. Water consumption is tightly bound to energy use, because without water we cannot mine, drill, frack, or cool thermoelectric and nuclear plants. A given household may save on average 16,200 gallons of water per year by installing rooftop solar.

New laser-based instrument designed to boost hydrogen research      (via sciencedaily.com) 

Researchers have developed an analytical instrument that uses an ultrafast laser for precise temperature and concentration measurements of hydrogen. Researchers describe a new coherent Raman spectroscopy instrument, made possible due to a setup that converts broadband light from a laser with short (femtosecond) pulses into extremely short supercontinuum pulses, which contain a wide range of wavelengths. Their new approach could help advance the study of greener hydrogen-based fuels for use in spacecraft and airplanes.

Sulfur shortage: A potential resource crisis looming as the world decarbonizes      (via sciencedaily.com) 

A new study highlights that global demand for sulfuric acid is set to rise significantly from '246 to 400 million tons' by 2040 -- a result of more intensive agriculture and the world moving away from fossil fuels. A projected shortage of sulfuric acid, a crucial chemical in our modern industrial society, could stifle green technology advancement and threaten global food security, according to a new study.

A key role for quantum entanglement      (via sciencedaily.com) 

A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement -- offering much broader security guarantees than previous schemes.

'Pulling back the curtain' to reveal a molecular key to The Wizard of Oz      (via sciencedaily.com) 

Many people and companies worry about sensitive data getting hacked, so encrypting files with digital keys has become more commonplace. Now, researchers have developed a durable molecular encryption key from sequence-defined polymers that are built and deconstructed in a sequential way. They hid their molecular key in the ink of a letter, which was mailed and then used to decrypt a file with text from a classic story.

Fuel cells: Novel multi-proton carrier complex as efficient proton conductor at high temps      (via sciencedaily.com) 

Fuel cells often fall short when it comes to operating at temperatures beyond 100 degrees Celsius owing to their dependence on water as a proton conduction medium. To overcome this issue, a team of researchers designed a new hydrogen-bonded starburst-shaped metal complex consisting of ruthenium (III) ion and six imidazole-imidazolate groups. The resulting single molecular crystal shows excellent proton conductivity even at temperatures as high as 180°C and as low as --70 °C.

Electric vehicles pass the remote road test      (via sciencedaily.com) 

A new study, which demonstrates that even the most rural areas of Australia are feasible for electric vehicles, provides new hope for how the technology could be spread around the most secluded locations in other parts of the world. The study found the vast majority of residents, or 93 per cent, could travel to essential services with even the lower-range of electric vehicles currently available on the Australian market, without needing to recharge en route.

Why natural gas is not a bridge technology      (via sciencedaily.com) 

The expansion of natural gas infrastructure jeopardizes energy transition, as natural gas is not a bridge technology towards a 100 per cent renewable energy system as defined by the Paris Climate Agreement. The researchers have examined the natural gas issue from five perspectives and given gas a fairly poor climate balance, comparable to that of coal or oil. They recommend that politicians and scientists revise the current assumptions about natural gas.
