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.....»»
Changing food consumers" choices may help cut greenhouse gases
Planet-warming greenhouse gas emissions associated with the global food supply chains induced by diets could fall by 17% if people change their food choices towards more plant-based diets, a new study reveals......»»
Detecting climate change using aerosols
Climate change is one of the most significant environmental challenges of present times, leading to extreme weather events, including droughts, forest fires, and floods. The primary driver of climate change is the release of greenhouse gases into the.....»»
Ammonia-free gallium nitride semiconductor production found to improve crystal quality, reduce environmental impact
Gallium nitride (GaN) semiconductors can now be grown without ammonia, a toxic chemical that needs a sophisticated detoxifying system before it can be released into the atmosphere. The new technique is not only more environmentally friendly but also.....»»
Is this how you get hot Jupiters?
When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, similar to what we're familiar with in our solar system......»»
Confined water gets electric: Study reveals dielectric response of water in nanopores
When water gets inside nanopores with sizes below 10 nanometers, new physics emerge: new phases of ice were observed and ultrafast proton transport was measured. Confined water also plays a role in biology, where aquaporins cross cellular membranes t.....»»
Aluminum scandium nitride films: Enabling next-gen ferroelectric memory devices
Imagine a thin film, just nanometers thick, that could store gigabytes of data—enough for movies, video games, and videos. This is the exciting potential of ferroelectric materials for memory storage. These materials have a unique arrangement of io.....»»
Studies find China-based emissions of three potent climate-warming greenhouse gases have spiked in past decade
When it comes to heating up the planet, not all greenhouse gases are created equal. They vary widely in their global warming potential (GWP), a measure of how much infrared thermal radiation a greenhouse gas would absorb over a given time frame once.....»»
Material with molecular trapdoor holds promise for highly selective gas adsorption
An international team led by scientists at City University of Hong Kong has found a flexible metal-organic framework (MOF) with one-dimensional channels that acts as a "molecular trapdoor" to selectively adsorb gases, such as carbon dioxide, in respo.....»»
Irish peat soils are far more vast than previously known, suggests study
New figures suggest peat soils cover 13% more area than previous peat soil maps, which are useful in land use planning—with peat soils critical in absorbing greenhouse gases (GHG) and helping to meet some of Ireland's most pressing environmental ch.....»»
Solar energy-driven H₂O₂ photosynthesis from water and oxygen using Ba-implanted ordered carbon nitride
H2O2, a green oxidant and clean fuel, is in high demand across chemical industries, environmental treatments, and even aerospace. However, traditional production methods rely on energy-intensive processes that are not environmentally friendly. Scient.....»»
Hurricanes Are Trapping Small Island Nations in Ever-Worsening Spirals of Debt
Damage from tropical storms like Beryl saddles islands with debt, which they have no hope of clearing before the next storm hits......»»
AI model harnesses physics to autocorrect remote sensing data
Turbulence, temperature changes, water vapor, carbon dioxide, ozone, methane, and other gases absorb, reflect, and scatter sunlight as it passes through the atmosphere, bounces off the Earth's surface, and is collected by a sensor on a remote sensing.....»»
Melting high-mountain glaciers would release greenhouse gases into atmosphere, suggest scientists
The retreat of high mountain glaciers has accelerated since the 1980s, resulting in increased glacier runoff. However, it remains uncertain whether melting mountain glaciers enhance or release greenhouse gases, and whether areas exposed to glacier re.....»»
Aerosols shown to increase size of cloud cells, causing greater radiative cooling under polluted conditions
Aerosols, often emitted alongside greenhouse gases, can brighten clouds and cause significant cooling. However, the uncertainty associated with aerosol–cloud interactions (ACIs) is large and potentially significant enough to mask a sizable portion.....»»
Videos show "nature run" of greenhouse gases over a year
Three videos developed as part of the CoCO2 research project coordinated by ECMWF show a "nature run" of greenhouse gases over the year 2021......»»
Study shows unbalanced air quality improvements can increase forest fires
If we want cleaner air, fewer forest fires, and less severe climate change, a new UC Riverside study shows we must reduce aerosol pollution and greenhouse gases like carbon dioxide at the same time......»»
Asian forests show resilience despite rising disturbances from climate change and human activities
Since 1850, global temperatures have been steadily rising. Human activities have significantly increased the emissions of greenhouse gases into the atmosphere, exacerbating the greenhouse effect and global warming. Forests in Asia have faced numerous.....»»
New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost
As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gases to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from thes.....»»
Countries Must Cut Climate Pollution, Ocean Court Rules
In its first climate change case, the International Tribunal for the Law of the Sea determined that a global ocean convention extends to greenhouse gases, meaning countries have an obligation to reduce them.....»»
New study offers a cleaner path for controlling water, transforming greenhouse gases
Scientists looking to convert carbon dioxide into clean fuels and useful chemicals often make hydrogen gas and carbonates as unwanted byproducts. A new paper from the UChicago Pritzker School of Molecular Engineering has found a cleaner path......»»
