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.....»»
Innovations in sustainable fashion
The global fashion sector, mainly the apparel and footwear industry, produced more greenhouse gases than France, Germany, and the UK combined in 2018, around 2.1 billion metric tons of CO2 emissions—approximately 4% of total global emissions, accor.....»»
Shifting food choices are reducing climate impact of the American diet
Changing dietary patterns in the U.S. are leading to lower emissions of food-related, climate-warming gases, according to a new research study, and half of the reduction can be attributed to eating less beef......»»
Scientists synthesize novel nitride and stabilize its hexazine rings at high pressure
In a recent study published in Nature Chemistry, scientists reported the synthesis of a novel nitride with metallic luster and hexazine rings—the result of a six-year effort in high-pressure science......»»
New materials for storing flammable industrial gases
How do I store more, and better? This summarizes the challenge of transporting flammable gases. To ensure industrial safety, these gases must be handled at defined temperature and pressure conditions that do not allow for optimal storage and release.....»»
Three Gorges Dam: Friend or foe of riverine greenhouse gases?
Dams are conventionally regarded as emitters of GHGs in large rivers. A team from Peking University of China, however, has disrupted this perception, based on whole system thinking applied to the Three Gorges Dam (TGD) on the Yangtze River in China......»»
Improving the composition of radiation protection glasses
Scientists at the Ural Federal University (UrFU) with colleagues from the Arabian Peninsula have improved the radiation protection properties of glass, in particular borate glasses (boron oxide-based glass). They introduced special additives into the.....»»
Bacteria generate electricity from methane
Generating power while purifying the environment of greenhouse gases should be achievable using bacteria. In a new publication, microbiologists from Radboud University have demonstrated that it is possible to make methane-consuming bacteria generate.....»»
"Too many people, not enough food" isn"t the cause of hunger and food insecurity
Nearly one in three people in the world did not have access to enough food in 2020. That's an increase of almost 320 million people in one year and it's expected to get worse with rising food prices and the war trapping wheat, barley and corn in Ukra.....»»
Want a Battery That Lasts? Play Hot and Cold
Researchers have designed a molten salt battery that turns solid at room temperature, trapping the energy inside......»»
Amazon rainforest foliage gases affect the Earth"s atmosphere
Plant-foliage-derived gases drive a previously unknown atmospheric phenomenon over the Amazon rainforest, according to a recent study by researchers at Pacific Northwest National Laboratory (PNNL)......»»
Researchers demonstrate new link between greenhouse gases and sea level rise
A new study provides the first evidence that rising greenhouse gases have a long-term warming effect on the Amundsen Sea in West Antarctica. Scientists from British Antarctic Survey (BAS) say that while others have proposed this link, no one has been.....»»
New polymer membrane tech improves efficiency of carbon dioxide capture
Researchers have developed a new membrane technology that allows for more efficient removal of carbon dioxide (CO2) from mixed gases, such as emissions from power plants......»»
Periodic volcanism may have triggered multiple Jurassic extinctions
Severe environmental crises led to a series of large-scale extinction events in the Jurassic period 178-186 million years (myr) ago. The turmoil has been ascribed to the abundant release of volcanic gases, but the temporal link between volcanism and.....»»
Underwater Permafrost Is a Big, Gassy Wild Card for the Climate
You’ve probably heard of permafrost, the frozen carbon-rich land. But it’s also thawing under the sea, burping up planet-warming gases......»»
Breakthrough application of moisture-trapping film to reduce heat stress in personal protective suits
A team of researchers from the National University of Singapore (NUS) has developed a novel super-hygroscopic material that enhances sweat evaporation within a personal protective suit, to create a cooling effect for better thermal comfort for users.....»»
Apple uses "world"s first" carbon free aluminium in iPhone SE
New smelting process produces oxygen rather than greenhouse gases......»»
A chip-scale broadband light source in silicon carbide
Optical frequency combs have changed science and technology as we know it. Responsible for measuring things like infrared and ultraviolet light, greenhouse gases, atomic clocks, and disease, optical frequency combs act as rulers that measure light. B.....»»
How a certain protein regulates up to two-thirds of the world"s methane emission
While methane accounts for about 16% of the abundance in the atmosphere of greenhouse gases—which also include carbon dioxide, nitrous oxide, water vapor—it is more than 25 times better than carbon dioxide at trapping heat. Two-thirds of global m.....»»
New method of bond detection could lead to cheaper, more efficient ways to capture carbon
University of Colorado Boulder researchers have developed a new tool that could lead to more efficient and cheaper technologies for capturing heat-trapping gases from the atmosphere and converting them into beneficial substances, like fuel or buildin.....»»
Effects of ancient carbon releases suggest possible scenarios for future climate
A massive release of greenhouse gases, likely triggered by volcanic activity, caused a period of extreme global warming known as the Paleocene-Eocene Thermal Maximum (PETM) about 56 million years ago. A new study now confirms that the PETM was preced.....»»
