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.....»»
Shanghai, Tokyo, New York, Houston spew most greenhouse gas of world cities
Cities in Asia and the United States emit the most heat-trapping gas that feeds climate change, with Shanghai the most polluting, according to new data that combines observations and artificial intelligence......»»
Industrial snow: Factories trigger local snowfall by freezing clouds
Anthropogenic aerosols, tiny solid and liquid air pollution particles, have masked a fraction of global warming caused by anthropogenic greenhouse gases. Climate researchers have known for decades that anthropogenic aerosols perturb liquid clouds by.....»»
Study finds four global policies could eliminate >90% of plastic waste and 30% of linked carbon emissions by 2050
A study released in Science determines that just four policies can reduce mismanaged plastic waste—plastic that isn't recycled or properly disposed of and ends up as pollution—by 91% and plastic-related greenhouse gases by one-third......»»
Scientists develop a phase-transformable membrane for efficient gas separation
Industrial gas separation, essential for clean energy and environmental protection, demands efficiency and adaptability. Current materials, however, lack the flexibility to selectively separate gases like carbon dioxide (CO2) and hydrogen (H2) while.....»»
Oldest depictions of fishing discovered in Ice Age art: Camp site reveals 15,800-year-old engravings of fish trapping
The Ice Age camp site of Gönnersdorf on the banks of the Rhine has revealed a groundbreaking discovery that sheds new light on early fishing practices. New imaging methods have allowed researchers to see intricate engravings of fish on ancient schis.....»»

Researchers from the IBB-UAB have developed a new class of nanostructures capable of trapping and neutralizing large quantities of the SARS-CoV-2 virus particles, both in liquid solutions and on the surface of materials......»»
Quantum vortices confirm superfluidity in supersolid
Supersolids are a new form of quantum matter that has only recently been demonstrated. The state of matter can be produced artificially in ultracold, dipolar quantum gases. A team led by Innsbruck physicist Francesca Ferlaino has now demonstrated a m.....»»
Precise layering in catalysts offers an improved way for building sustainable chemicals
Motivated to turn greenhouse gases like carbon dioxide into high value chemicals like methanol, EPFL chemical engineers have developed a new method to make catalysts. Catalysts are major tools in the chemical industry and are largely made to make pet.....»»
Specially designed transistors allow researchers to "hear" defects in a promising nanomaterial
An international research team led by NYU Tandon School of Engineering and KAIST (Korea Advanced Institute of Science and Technology) has pioneered a new technique to identify and characterize atomic-scale defects in hexagonal boron nitride (hBN), a.....»»
Old data yield new secrets as NASA"s DAVINCI preps for Venus trip
Due to launch in the early 2030s, NASA's DAVINCI mission will investigate whether Venus—a sweltering world wrapped in an atmosphere of noxious gases—once had oceans and continents like Earth......»»
Researchers achieve tunable coherent population trapping in a double quantum dot system
A research team has achieved coherent population trapping (CPT) in a semiconductor double quantum dot (DQD) system......»»
Theoretical study demonstrates existence of giant photocaloric effects in ferroelectric perovskites
Solid-state cooling is a promising alternative cooling technique that does not rely on the use of gases or liquids, like conventional refrigeration systems, but instead utilizes the properties of solid materials to refrigerate. This alternative cooli.....»»
The other greenhouse gases warming the planet
While carbon dioxide, or CO2, is the best known greenhouse gas, several others, including methane and nitrous oxide, are also driving global warming and altering the Earth's climate......»»
Scientists offer a detailed look at the skeleton of an ancient predator that thrived in extreme conditions
Imagine a world on the brink of collapse: volcanic eruptions spewing toxic gases, oceans turning acidic, and up to 90% of Earth's species vanishing in the blink of an eye. This was the reality at the end of the Permian Period, around 252 million year.....»»
Beyond "one pore at a time": New method of generating multiple, tunable nanopores
Nanoporous membranes with atomic-scale holes smaller than one-billionth of a meter have powerful potential for decontaminating polluted water, pulling valuable metal ions from the water, or for osmotic power generators......»»
Researchers create orientation-independent magnetic field-sensing nanotube spin qubits
Purdue University researchers have developed patent-pending one-dimensional boron nitride nanotubes (BNNTs) containing spin qubits, or spin defects. The BNNTs are more sensitive in detecting off-axis magnetic fields at high resolution than traditiona.....»»
Inland waters crucial for accurate climate assessments, research suggests
Inland waters release substantial amounts of greenhouse gases, but this is rarely included in climate assessments. New research from Umeå University shows that not accounting for carbon fluxes between land and water systems leads to incorrect assess.....»»
New synthesis strategy could speed up PFAS decontamination
Rice University engineers have developed an innovative way to make covalent organic frameworks (COFs), special materials that can be used to trap gases, filter water and speed up chemical reactions. COFs have the potential to address significant envi.....»»
