Researchers from North Carolina State University and Qatar University have developed a new "high-entropy" metal alloy that has a higher strength-to-weight ratio than any other existing metal material.
(Phys.org) —It only sounds like science fiction. To test a new technology for landing heavy payloads on Mars, NASA is about to drop a flying-saucer shaped vehicle from a helium balloon high above Earth's surface.
(Phys.org) —Although sodium-ion (Na-ion) batteries don't perform as well as lithium-ion (Li-ion) batteries, they have the potential to be a cheaper alternative. In a new study, scientists have designed a new cathode for ...
(Phys.org) —In 1921, a Russian entomologist named Boris Uvarov made a curious discovery. He noticed that a single species of grasshopper could transform its appearance and behavior, depending on its population density. ...
A group of scientists at the University of Oxford and York are taking their inspiration from plants to develop a solar fuel system, or 'artificial photosynthesis' system (APS) that is more efficient than the process that ...
You must have heard that spider silk is stronger than steel. We all want to believe that there are wonder materials in nature that are far superior to human-made ones. But the problem with statements that sound too good to ...
(Phys.org) —On today's farms, plastic is as ubiquitous as dirt. From plastic film that wraps silage to leftover pesticide containers to the thin trays that hold seedlings, plastic plays an important role. But in the dark ...
Scientists at the Department of Physics of the University of Oulu have teamed up with scientists in France, Russia and Japan to propose a new experimental method for researching positively charged ions. The study, In the ...
The Wildlife Conservation Society, Zoological Society of London, and Endangered Wildlife Trust have joined representatives from Ethiopia, Kenya, and Uganda at the Convention on International Trade in Endangered Species of ...
(Phys.org)—The world of rechargeable batteries is full of trade-offs. While lithium-ion (Li-ion) batteries are currently the most commercially successful, their low energy density doesn't allow for a long driving range. ...
