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.....»»
Study finds bacteria use organic phosphorus and release methane in the process
Off Barbados, researchers from Bremen have investigated how bacteria inadvertently release methane in order to obtain phosphorus—with significant effects on atmospheric greenhouse gases......»»
How lab-made catalysts can help convert difficult greenhouse gases
Natural gas consists of light hydrocarbons such as methane and ethane. Such gases are more potent greenhouse gases than CO2, are constantly released into the atmosphere from natural gas wells, and are more difficult to store than, for example, their.....»»
Harmful gases could be detected on-the-spot with new way to generate powerful lasers
Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed a novel method to produce intense and ultra-fast lasers that holds promise for making precise devices that can speed up how quickly trace amounts of pollutan.....»»
Enhanced laser heterodyne spectroscopy helps atmospheric greenhouse gas measurements
A research team led by Prof. Gao Xiaoming from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has improved the measurement accuracy of atmospheric greenhouse gases, including carbon dioxide, by using an Erbium-doped Fiber.....»»
Researchers correct overestimation by "hot model" climate projections on warming in China
Changes in mean temperature and temperature extremes at regional scale under a warmer climate have received much attention. A subset of CMIP6 climate models, known as "hot models," have been projecting more significant warming due to greenhouse gases.....»»
Scientists close the cycle on recycling mixed plastics
Little of the mixed consumer plastics thrown away or placed in recycle bins actually ends up being recycled. Nearly 90% is buried in landfills or incinerated at commercial facilities that generate greenhouse gases and airborne toxins. Neither outcome.....»»
Wildfire smoke leaves harmful gases in floors and walls—air purifiers aren"t enough, new study shows
When wildfire smoke turns the air brown and hazy, you might think about heading indoors with the windows closed, running an air purifier or even wearing a mask. These are all good strategies to reduce exposure to the particles in wildfire smoke, but.....»»
New noble-metal-free electrocatalyst decreases the energy required to generate hydrogen gas from water
As a combustible fuel, the burning of hydrogen gas does not contribute to global warming. Today, the majority of hydrogen gas is generated from fossil fuels, however, and this process releases greenhouse gases into the atmosphere. Generating hydrogen.....»»
Researchers: There is a need for more accurate accounting of nitrous oxide from agricultural crop residues
There is a need for changing the way of accounting greenhouse gases from agriculture. The current inventory of nitrous oxide from plant residues relies solely on the amount of nitrogen in the residues, while crucial factors such as the degradability.....»»
Only 1% of chemical compounds have been discovered—here"s how we search for others that could change the world
The universe is flooded with billions of chemicals, each a tiny pinprick of potential. And we've only identified 1% of them. Scientists believe undiscovered chemical compounds could help remove greenhouse gases, or trigger a medical breakthrough much.....»»
Key Biden Climate Pollution Metric Is Safe--For Now
Supreme Court justices declined to decide whether the Biden administration is placing too high a value on the cost to society of spewing carbon and other planet-warming gases.....»»
Creating a broadband diffractive graphene orbital angular momentum metalens by laser nanoprinting
Optical beams carrying orbital angular momentum (OAM) attract widespread attention and play an important role in optical data storage, optical communications, quantum information processing, super-resolution imaging, and optical trapping and manipula.....»»
Using metal organic frameworks to provide a safer and cleaner way to handle fluorinated gases
A team of chemists from Cornell University, the Korea Institute of Science and Technology and Southern Methodist University, has found a way to use metal organic frameworks to provide a safer and cleaner way to handle fluorinated gases. Their study i.....»»
Drier savannas, grasslands store more climate-buffering carbon than previously believed
Savannas and grasslands in drier climates around the world store more heat-trapping carbon than scientists thought they did and are helping to slow the rate of climate warming, according to a new study......»»
Capturing carbon dioxide with electricity: A microbial enzyme inspires electrochemistry
Humans continuously emits greenhouse gases, worsening global warming. For example, carbon dioxide (CO2) accumulates dramatically over the years and is chemically very stable. Yet, some microbes capture CO2 using highly efficient enzymes. Scientists f.....»»
Flour-derived borocarbonitride enriched with boron-oxygen for the oxidative dehydrogenation of propane to olefins
In a study published in the journal Science China Chemistry, catalytic performance was investigated using a fixed-bed reactor and the structure-activity relationship was studied by combining various characterizations with DFT calculations......»»
Team designs nitride-reinforced NbMoTaWHfN refractory high-entropy alloy
A new generation of refractory alloys with excellent high-temperature performance is urgently demanded for aero-engines, gas turbines, and nuclear power plants. As the service temperature of their hot-ends is reaching 1800 °C or even higher, traditi.....»»
Colorado has a new plan to reduce greenhouse gases. Critics say it fails those most impacted by air pollution
Colorado's air regulators have approved a new rule that will require the state's 18 largest manufacturers to reduce their greenhouse gas emissions, but the plan is receiving pointed criticism from environmental advocates who say loopholes will allow.....»»
Gases from Philippine volcano sicken dozens of children, prompting school closures in nearby towns
Smog containing gases from a restive Philippine volcano sickened dozens of students and prompted 25 towns and cities to shut their schools on Friday as a health precaution, officials said......»»
