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.....»»
Recycling greenhouse gases: Nanoparticles on perovskite crystals avoid "coking" effect
Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted into something useful: this approach is called "carbon capture and utilization." Special catalysts are needed for this. Until now, however, the problem.....»»
BAMS report: Record-high greenhouse gases, sea levels in 2021
Greenhouse gas concentrations, global sea levels and ocean heat content reached record highs in 2021, according to the 32nd annual State of the Climate report......»»
Greenhouse gas, sea levels at record in 2021: NOAA
Earth's concentration of greenhouse gases and sea levels hit new highs in 2021, a US government report said Wednesday, showing that climate change keeps surging ahead despite efforts to curb emissions......»»
Using nanopores to detect epigenetic changes faster
Changes known as epigenetic modifications play an important role in cancer development. Being able to analyze them quickly and reliably could contribute significantly to the further development of personalized therapy. A research team from the Instit.....»»
Elemental research: Scientists apply boron to tungsten components in fusion facilities
What is the connection between boron, an element in a common household cleaner, and tokamaks, ring-shaped fusion facilities that heat fuel to million-degree temperatures? Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics La.....»»

A UBC Okanagan researcher is suggesting changes to fur trapping practices to help prevent the accidental amputation of grizzly bear toes......»»
Black hole-inspired thermal trapping with graded heat-conduction metadevices
Jiping Huang's group (Department of physics, Fudan University) and Cheng-Wei Qiu's group (Department of Electrical and Computer Engineering, National University of Singapore) collaborated to complete this study published in National Science Review. T.....»»
Federal study: New climate law to slice carbon pollution 40%
Clean energy incentives in the new spending package signed this week by President Joe Biden will trim America's emissions of heat-trapping gases by about 1.1 billion tons (1 billion metric tons) by 2030, a new Department of Energy analysis shows......»»
New Evidence Points to the Moon Once Being Part of Earth
Gases trapped in lunar meteorites hint that the moon was formed out of material displaced from Earth after a planetary collision......»»
Matter at extreme conditions of very high temperature and pressure turns out to be remarkably simple and universal
Scientists at Queen Mary University of London have made two discoveries about the behavior of "supercritical matter"—matter at the critical point where the differences between liquids and gases seemingly disappear......»»
Customized fiber generates Bessel beams
An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications......»»
Record Amount of Seaweed Chokes Caribbean Beaches and Shoreline
Bruce66423 writes: A record amount of seaweed is smothering Caribbean coasts from Puerto Rico to Barbados as tons of brown algae kill wildlife, choke the tourism industry and release toxic gases. More than 24 million tons of sargassum blanketed the A.....»»
Record amount of seaweed is choking shores in the Caribbean
Near-record amounts of seaweed are smothering Caribbean coasts from Puerto Rico to Barbados, killing fish and other wildlife, choking tourism and releasing stinky, noxious gases......»»
Nanoshell catalysts turn greenhouse gases into useful chemicals
A byproduct of landfilling, livestock farming, coal mining and other human activities, methane emissions are one of the key drivers of climate change......»»
GaN chargers are a game-changer: UGreen 200W and OneWorld65 show why
GaN chargers have been around for a while now, but it’s only relatively recently that the price of the gallium nitride (GaN) has fallen the the point where they are becoming mainstream. The main benefit is high power in a small package. The clai.....»»
This major breakthrough could end PC overheating worries for good
University researchers think cubic boron arsenide could potentially be the "best semiconductor material ever"......»»
A nanokelvin microwave freezer for molecules
When a highly diluted gas is cooled to extremely low temperatures, bizarre properties are revealed. Thus, some gases form a so-called Bose-Einstein condensate—a type of matter in which all atoms move in unison. Another example is supersolidity: a s.....»»
Conserving critical habitat in face of climate change in Midwestern lakes by managing watershed land use
Lakes across the Midwest are losing cold, oxygenated habitat as a result of climate change and nutrient pollution. This loss of critical habitat has negative consequences for water quality, fish, and the production of greenhouse gases. While data sho.....»»
Silicon, watch out — researchers found the future of semiconductors
Scientists have just found that using cubic boron arsenide in semiconductors could prove to be much better than silicon. Is silicon on its way out the door?.....»»
