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.....»»
US energy industry methane emissions are triple what government thinks, study finds
American oil and natural gas wells, pipelines and compressors are spewing three times the amount of the potent heat-trapping gas methane as the government thinks, causing $9.3 billion in yearly climate damage, a new comprehensive study calculates......»»
Inland waters are a blind spot in greenhouse gas emissions
Inland waters such as rivers, lakes, reservoirs, and ponds may release copious amounts of greenhouse gases, but this possibility is not well understood. In a new review published in theJournal of Geophysical Research: Biogeosciences, Qianqian Yang an.....»»
Global warming may be behind an increase in the frequency and intensity of cold spells
Global warming caused by increased concentrations of greenhouse gases is already affecting our lives. Scorching summers, more intense heat waves, longer drought periods, more extended floods, and wilder wildfires are consequences linked to this warmi.....»»
Training drones to detect greenhouse gas sources
How do you map something that is both invisible and odorless? Researchers at the University of Oslo have trained drones to find the best places to measure greenhouse gases on their own......»»
Researchers develop a more precise carbon footprint measurement method
Bayreuth researchers want to calculate the carbon footprint of companies more accurately in the future. The term "carbon footprint" refers to the recording of climate-impacting greenhouse gases and the compilation of these in a greenhouse gas balance.....»»
Trapping and excitation of the simplest molecule: Precise measurement matches theoretical predictions
The simplest possible molecule H2+ was one of the very first molecules to form in the cosmos. This makes it significant for astrophysics, but also an important object of research for fundamental physics. However, it is difficult to study in experimen.....»»
Novel theory-based evaluation gives a clearer picture of fusion in the sun
Most of the energy from the sun and other stars comes from a chain of nuclear fusion reactions. The end of this chain is marked by the fusion of protons with beryllium-7 to form boron-8. This process is key in determining the flow of high-energy sola.....»»
Belgian researchers provide a strong boost to sustainable agriculture
Much has been written about the European Climate law and the European Nitrate Directive. Besides social concerns, drastically reducing greenhouse gases by 2030 and structurally lowering the use of nitrogen in agriculture poses significant challenges......»»
CERN researchers measure speed of sound in the quark–gluon plasma more precisely than ever before
Neutron stars in the universe, ultracold atomic gases in the laboratory, and the quark–gluon plasma created in collisions of atomic nuclei at the Large Hadron Collider (LHC): they may seem totally unrelated but, surprisingly enough, they have somet.....»»
Trapping sulfate to benefit health, industry and waterways
Scientists have developed a new method to measure and remove sulfate from water, potentially leading to cleaner waterways and more effective nuclear waste treatments......»»
New thermometry method reveals that compressing a gas may lead to cooling
An international research team from Innsbruck and Geneva has developed a new thermometry method to measure temperatures for low-dimensional quantum gases. With this method it was found that compressing a gas may lead to cooling. The results on this c.....»»
Quantum simulation with ultracold fermions unveils pairing pseudogap
A research team has, for the first time, observed and quantitatively characterized the many-body pairing pseudogap in unitary Fermi gases. This achievement, pursued by the ultracold atomic community for nearly two decades, resolves longstanding debat.....»»
Comparing carbon-trapping capacities of anoxic basins
Humans will need to both drastically reduce emissions and remove at least 10 gigatons of carbon dioxide from the atmosphere per year to avoid the worst effects of climate change, according to the Intergovernmental Panel on Climate Change 2023 synthes.....»»
Improving Arctic greenhouse gas sink and source estimates with field measurements, remote sensing
A new study investigates the sinks and sources of key greenhouse gases of carbon dioxide, methane, and nitrous oxide in the Arctic landscape with a spatial resolution of only a few square meters. Vegetation and soil conditions explain the differences.....»»
Trees struggle to "breathe" as climate warms, researchers find
Trees are struggling to sequester heat-trapping carbon dioxide (CO2) in warmer, drier climates, meaning that they may no longer serve as a solution for offsetting humanity's carbon footprint as the planet continues to warm, according to a new study l.....»»
Study tracks how wetland tree stem emissions vary by season, location, and hydrological conditions
The recent rise in atmospheric methane (CH4) has drawn increased attention to the potent greenhouse gas, which is approximately 45 times more powerful than carbon dioxide at trapping heat in the atmosphere. About 60% of global methane emissions are a.....»»
Methane pulses on Mars possibly driven by atmospheric pressure changes
New research shows that atmospheric pressure fluctuations that pull gases up from underground could be responsible for releasing subsurface methane into Mars's atmosphere; knowing when and where to look for methane can help the Curiosity rover search.....»»
Closing the green gap: A cubic III-nitride active layer with 32% internal quantum efficiency
Color mixing is the process of combining two or more colors: red and green make yellow, blue and red make purple, red and green and blue make white. This process of mixing colors is the basis for the future of solid-state lighting. While currently wh.....»»
Researchers develop high-efficiency carbon dioxide electroreduction system for reducing carbon footprint
Global warming continues to pose a threat to human society and ecological systems, and carbon dioxide accounts for the largest proportion of the greenhouse gases that dominate climate warming......»»
Old forests critically important for slowing climate change, merit immediate protection from logging
Forests are an essential part of Earth's operating system. They reduce the buildup of heat-trapping carbon dioxide in the atmosphere from fossil fuel combustion, deforestation and land degradation by 30% each year. This slows global temperature incre.....»»
