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.....»»
Human rights law demands climate change adaptation, researchers say
Continued high emissions of greenhouse gases mean the well-being of all people now depends on profound changes in policies and practices to effect climate change adaptation......»»
To save the climate, the oil and gas sector must slash planet-warming operations, report says
The oil and gas sector, one of the major emitters of planet-warming gases, will need a rapid and substantial overhaul for the world to avoid even worse extreme weather events fueled by human-caused climate change, according to a report released Thurs.....»»
U.S. finalizes rule requiring states to set transportation emission targets
The Federal Highway Administration, part of the U.S. Department of Transportation, said the rule adds a new method for measuring and reporting greenhouse gases associated with transportation and allows states to track performance......»»
Research provides new methods to improve capture rates of ground-dwelling arthropods using pitfall trapping
Pitfall traps are commonly used for capturing ground-dwelling arthropods, particularly beetles, ants, and spiders. The efficiency of a pitfall trapping system is significantly influenced by the quantity and size of traps, the spatial distribution of.....»»
Scientists set the stage for quantum chemistry in space on NASA"s cold atom lab
For the first time in space, scientists have produced a mixture of two quantum gases made of two types of atoms. Accomplished with NASA's Cold Atom Laboratory aboard the International Space Station, the achievement marks another step toward bringing.....»»
Greenhouse gases hit record high in 2022: UN
Greenhouse gas concentrations in the atmosphere hit new record highs in 2022, with no end in sight to the rising trend, the United Nations warned Wednesday......»»
Q&A: How can cities fight climate change and still stay within legal guardrails?
Many U.S. cities are leading the way in cutting emissions of greenhouse gases, with mandates on more efficient buildings, renewable energy and expansion of mass transit. But often these efforts face hurdles in the form of state and federal laws that.....»»
Pushing the limits of gas sensing technology
The world has become increasingly industrialized over the past few centuries, bringing all sorts of technology and conveniences to the masses. However, workers in industrial environments are often at risk of exposure to many dangerous gases, such as.....»»
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.....»»
