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.....»»
Montana weighs wolf hunt limits; 23 from Yellowstone killed
Montana wildlife commissioners on Friday will consider if gray wolf hunting and trapping should continue in areas bordering Yellowstone National Park after 23 of the animals roamed from the park and were killed over the past several months......»»
Humanity Has Turned Land Itself Into a Menace
All of our meddling has primed Earth to collapse under cities and belch greenhouse gases, a nasty feedback loop that’s accelerating global warming......»»
Shifting ocean closures best way to protect animals from accidental catch
Accidentally trapping sharks, seabirds, marine mammals, sea turtles and other animals in fishing gear is one of the biggest barriers to making fisheries more sustainable around the world. Marine protected areas—sections of the ocean set aside to co.....»»
Large Auger coefficient myth in III-nitride LEDs debunked?
Indium gallium nitride (InGaN)-based, blue-light-emitting diodes are the backbone of solid-state lighting (SSL). Unfortunately, their efficiency peaks under low current densities (.....»»
How deep-sea worms help keep natural gases on ice
It is well known that natural gas hydrates, crystalline lattices of hydrogen-bonded water molecules that encapsulate small hydrocarbon molecules, on the ocean floors constitute both a potential accelerator of climate change and one of the greatest en.....»»
Climate change: Thawing permafrost a triple-threat
Thawing Arctic permafrost laden with billions of tonnes of greenhouse gases not only threatens the region's critical infrastructure but life across the planet, according a comprehensive scientific review......»»
Common household cleaner can boost effort to harvest fusion energy on Earth
Scientists have found that adding a common household cleaning agent—the mineral boron contained in such cleaners as borax—can vastly improve the ability of some fusion energy devices to contain the heat required to produce fusion reactions on Ear.....»»
Production of 8-inch third-gen semiconductors unlikely to increase soon
Although demand for third-generation semiconductors has been stably increasing, production capability for 8-inch gallium nitride (GaN) and silicon carbide (SiC) wafers will unlikely increase in a short period of time, according to industry sources......»»
Researchers find that iodine in desert dust destroys ozone
When winds loft fine desert dust high into the atmosphere, iodine in that dust can trigger chemical reactions that destroy some air pollution, but also let greenhouse gases stick around longer. The finding, published today in the journal Science Adva.....»»
From the oilfield to the lab: How a special microbe turns oil into gases
Microorganisms can convert oil into natural gas, i.e. methane. Until recently, it was thought that this conversion was only possible through the cooperation of different organisms. In 2019, Rafael Laso-Pérez and Gunter Wegener from the Max Planck In.....»»
Trapping vortices in thin superfluid films
Physicists at the University of Queensland have shed light upon how tiny whirlpools (vortices) get stuck to obstacles in superfluids......»»
Opening a 50-year-old Christmas present from the moon
A pretty special gift unwrapping will soon take place—a piercing tool built by ESA will open a moon soil container from Apollo 17 that has gone untouched for nearly 50 years. The opening will allow the extraction of precious lunar gases which may h.....»»
Taiwan chipmakers gearing up for WBG semiconductors
Taiwan-based chipmakers, led by foundry TSMC and silicon wafer supplier GlobalWafers, are gearing up to tap into the market for gallium nitride (GaN), silicon carbide (SiC) and other compound semiconductors with high bandgaps......»»
In the fight against climate change, China is doing more than you think, but still not enough
When it comes to climate change, no nation is more important than China. It consumes more coal than the rest of the world combined, and it is the leading emitter of greenhouse gases, accounting for nearly 30% of global emissions......»»
Using green tea as reducing reagent for the preparation of nanomaterials to synthesize ammonia
Researchers have shown that green tea can be used as a reducing reagent for the preparation of nanomaterials to synthesize ammonia. Compared with bulk graphitic carbon nitride, the optimal sample had 2.93-fold photocatalytic nitrate reduction to ammo.....»»
New computational approach predicts chemical reactions at high temperatures
Extracting metals from oxides at high temperatures is essential not only for producing metals such as steel but also for recycling. Because current extraction processes are very carbon-intensive, emitting large quantities of greenhouse gases, researc.....»»
Iceland"s journey to the centre of the Earth
With its large crater lake of turquoise water, plumes of smoke and sulphurous bubbling of mud and gases, the Krafla volcano is one of Iceland's most awe-inspiring natural wonders......»»
Hubble witnesses shock wave of colliding gases in Running Man Nebula
Mounded, luminous clouds of gas and dust glow in this Hubble image of a Herbig-Haro object known as HH 45......»»
For the first time, DNA and proteins sensed by de novo-designed nanopore
Researchers in Japan have designed the first bottom-up designed peptides, comprising chains of amino acids, that can form artificial nanopores to identify and enable single molecule-sorting of genetic material in a lipid membrane......»»
Can defects turn inert materials into useful, active ones?
Demonstrating that a material thought to be always chemically inert, hexagonal boron nitride (hBN), can be turned chemically active holds potential for a new class of catalysts with a wide range of applications, according to an international team of.....»»
