July 20, 2023 —Today's catalysts for removing unburnt methane from natural-gas engine exhaust are either inefficient at low, start-up temperatures or break down at higher operating temperatures. A new ...
July 20, 2023 —A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs to be done, ...
June 6, 2023 —As smart electronic devices become smaller and more powerful, they can generate a lot of heat, leading to slower processing times and sudden shutdowns. Now researchers use an electrospinning approach ...
June 1, 2023 —Scientists have identified a method for improving the thermal conductivity of thin metal films in semiconductors using surface waves for the first time in the ...
May 31, 2023 —There are many effects of climate change. Perhaps the most broadly known is global warming, which is caused by heat building up in various parts of the Earth system, such as the atmosphere, the ...
May 30, 2023 —The next generation of sustainable energy technology might be built from some low-tech materials: rocks and the sun. Using a new approach known as concentrated solar power, heat from the sun is ...
May 25, 2023 —Scientists have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures -- a scale trillion times lower than routinely ...
May 19, 2023 —Researchers have developed a new reliable and durable sensor that can work in temperatures as high as 900 degrees Celsius or 1,650 degrees Fahrenheit and can be used in multiple ...
May 11, 2023 —Improved cookstoves, which are widely used for cooking in developing countries, produce twice as many harmful ultrafine air pollution particles (PM0.1) as conventional stoves, according to a new ...
Apr. 24, 2023 —A new smart material is activated by both heat and electricity, making it the first ever to respond to two different ...
Apr. 18, 2023 —Engineers find the hydrogel polyethylene glycol (PEG) doubles its water absorption as temperatures climb from 25 to 50 C, and could be useful for passive cooling or water harvesting in warm ...
Apr. 18, 2023 —A tiny biobattery that could still work after 100 years has been ...
Apr. 18, 2023 —研究人员正在研究激进的即兴表演的新方法ve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly ...
Apr. 17, 2023 —Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its ...
Apr. 14, 2023 —New technology advances solar-cell production and recycling. New microwave technology will improve the manufacture of solar cells and make them easier to ...
Apr. 13, 2023 —Scientists have developed an extremely small and fast nano-excitonic ...
Apr. 13, 2023 —By using a new method, precious metals can be efficiently recovered from thin-film solar cells. The method is also more environmentally friendly than previous methods of recycling and paves the way ...
Apr. 13, 2023 —They've been called 'dream' plastics: polyhydroxyalkanoates, or PHAs. Already the basis of a fledgling industry, they're a class of polymers naturally created by living ...
Apr. 11, 2023 —Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the ...
Apr. 10, 2023 —Engineers have invented a fabric that concludes the 80-year quest to make a synthetic textile modeled on polar bear fur. The results are already being developed into commercially available ...
