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.....»»
Novel method examines the gas-liquid interface in new detail
The interface between gases and liquids is found throughout nature. It is also important to many industrial processes. To improve understanding of the gas-liquid interface, researchers have developed an apparatus to study reactions between gas molecu.....»»
Anker’s next-gen GaN chargers offer more power in smaller packages
Anker has unveiled the next generation of Gallium Nitride (GaN) technology with powerful chargers that can keep up with even your most power-hungry devices......»»
Researchers report high carrier mobility of cubic boron arsenide
Cubic boron arsenide (c-BAs), a semiconductor with ultrahigh thermal conductivity comparable to diamond, has attracted wide attention since 2018, with many people wondering whether it is suitable for transistors......»»
Porous crystals bind fluorine-containing greenhouse gases
Emissions of greenhouse gases contribute significantly to global warming. Not only carbon dioxide (CO2) but also fluorine-containing gases—including so-called per- or polyfluorinated hydrocarbons, or PFCs—have a significant share in this developm.....»»
The Dangerous Chemicals Lurking Inside Shipping Containers
Seizure-inducing methyl bromide and carcinogenic formaldehyde are only some of the poisonous gases scientists found inside cargo containers......»»
Bacteria could help to capture greenhouse gases
Carbon dioxide is an important molecule necessary for life on Earth. Trees need CO2 for photosynthesis, crops produce higher yields in its presence, and some bacteria can transform it into food. The molecule is even an important part of human health,.....»»
"Net zero"? "Carbon neutral"? Climate change jargon got you confused? Let us explain
Net zero what? Carbon sequestration who? And what on Earth do greenhouses have to do with gases?.....»»
Flashing creates hard-to-get 2D boron nitride
Rice University scientists who "flash" materials to synthesize substances like graphene have turned their attention to boron nitride, highly valued for its thermal and chemical stability......»»
Genetically-enhanced biocontrols could help fight large invasive mammals
Invasive alien mammals can have catastrophic impacts on native flora and fauna, causing species extinctions and driving profound environmental change. Classical control methods such as poison baiting, trapping, or hunting are currently not feasible o.....»»
Climate models may underestimate future floods
Climate models may be significantly underestimating how extreme precipitation will become in response to a rise in greenhouse gases in the atmosphere, a new Yale-led study finds......»»
Rampant wildfires once led to global mass extinction, scientists say. Can it happen again?
A long time ago, the carbon was rock, buried in the earth as securely as a secret. Then an environmental catastrophe of unprecedented scale began. The rocks burned, and the atoms inside them disassembled into carbon dioxide and other greenhouse gases.....»»
Review of technologies that boost potential for carbon dioxide conversion to useful products
The excessive emission of greenhouse gases, especially carbon dioxide, is rapidly raising the average global temperature. Capturing the carbon dioxide and converting it to useful fuels and chemicals can be an ideal way to reduce carbon dioxide concen.....»»
US Supreme Court limits government powers to curb greenhouse gases
The US Supreme Court ruled Thursday that the government's key environmental agency cannot issue broad limits on greenhouse gases, sharply curtailing the power of President Joe Biden's administration to battle climate change......»»
Laser writing may enable "electronic nose" for multi-gas sensor
Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution, thanks to a Penn State collaboration. Huanyu "Larry" Cheng, assistant professor of engineering science and mechanics in th.....»»
Team reassesses greenhouse gas emissions from African lakes
The emissions of carbon dioxide (CO2) and methane (CH4)—the most potent greenhouse gases—into the atmosphere from African lakes are reassessed in a study undertaken by the Laboratory of Chemical Oceanography (FOCUS research unit / Faculty of Scie.....»»
Exploring nature"s own assembly line
Today the raw ingredients for virtually all industrial products, ranging from medicines to car tires, come from non-renewable chemical feedstocks. They are produced in fossil fuel refineries that emit greenhouse gases, such as carbon dioxide. However.....»»
Single-atom tractor beams power chemical catalysis
By trapping light into tiny gaps only a few atoms wide, a team from the NanoPhotonics Center at the Cavendish Laboratory at the University of Cambridge has magnified optical forces a thousand-fold, strong enough to force atoms into positions that dri.....»»
TAS gearing up for SiC, GaN device sampling
Taiwan-Asia Semiconductor (TAS, formerly Opto Tech) will start sending samples of gallium nitride (GaN) and silicon carbide (SiC) devices in 2023, according to the company......»»
Large-scale cultivation of microalgae can clean emissions from industry, can also be used in Nordic climate
Microalgae can recover greenhouse gases and nutrients from industrial waste. This technology can be used to reduce climate footprint and eutrophication. Lina Mattsson's dissertation in ecology shows that microalgae can also be used in the Nordic clim.....»»
Researchers use fluorine-doping method to construct catalysts with enhanced performance
As industry has developed over the past century, excess carbon dioxide emission had led to climate problems and greenhouse effects. Scientists are constantly working toward solutions for the problems of greenhouse gases, which are warming the earth's.....»»
