Trapping gases better with boron nitride "nanopores"
What is common between a technology for storing energy in a solar cell and that for water purification? They both rely on the use of porous materials, or more specifically, 'nanoporous' materials that can trap gas molecules within narrow spaces on th.....»»
How keeping trees when clearing pastures could reduce climate consequences
Land use change, like cutting down a forest to make way for agriculture, can be a major contributor to climate change by releasing greenhouse gases into the atmosphere. Researchers at the University of New Hampshire studied a practice known as silvop.....»»
Chipmakers brace for more trouble as Russia limits exports of rare gases
The semiconductor industry just can't catch a break. After two years of pandemic-fueled supply bottlenecks, Russia, one of the world's biggest suppliers of industrial gases used to make chips, has started to limit its exports......»»
Martian meteorite upsets planet formation theory
A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as hydrogen, carbon, oxygen, nitrogen and noble gases as they form. The work is published June 16 in Science......»»
New method helps exfoliate hexagonal boron nitride nanosheets
Chinese researchers recently reported an innovative mechanical process for controllably exfoliating hexagonal boron nitride nanosheets (h-BNNSs).This method, known as the "water-icing triggered exfoliation process," was proposed by Prof. Zhang Junyan.....»»

Including all types of emissions shortens timeline to reach Paris Agreement temperature targets
Countries around the world pledged in the Paris Agreement to limit warming to 1.5 degrees Celsius, or, at most, 2 degrees Celsius. As emissions rates gradually begin to decline, countries are looking at how many greenhouse gases can still be emitted.....»»
Designing the perfect membrane for clean separation of gases
Selective removal of detrimental gases, e.g., hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas (CH4) could become simpler and highly effective using a new class of oriented mixed-matrix metal-organic framework (MMMOF) membrane develop.....»»
Salt may be the key to life on Earth and beyond
The composition of the atmosphere, especially the abundance of greenhouse gases, influences Earth's climate. Researchers at Purdue University, led by Stephanie Olson, assistant professor of earth, atmospheric, and planetary sciences, have recently fo.....»»

How to explain localized gap modes in Bose-Einstein condensates
Bose-Einstein condensates (BECs), created in ultracold bosonic atoms and degenerate quantum gases, are a macroscopic quantum phenomenon and are considered as a single particle in mean-filed theory. By preparing the BECs or ultracold atomic gases onto.....»»
Catalytic synthesis of phenols with nitrous oxide
The emission of greenhouse gases threatens the global environment, and scientists around the world are increasingly committed to addressing this issue. While many research groups focus on carbon dioxide (CO2) or methane (CH4) revalorization strategie.....»»
What are HEPA filters, and can you clean them?
