Scientists discover why rain drops can damage metal protective coatings
3+ hour, 25+ min ago (1355+ words) Drops can become electrically charged as they slide across surfaces. If they then fall onto a coating—such as on a car—the coating can be corroded by the drop’s electrical discharge and permanently damaged. (CREDIT: Katharina Maisenbacher / MPI-P) A…...
Ultrathin ruthenium dioxide discovery could enable faster, smaller and more efficient computer devices
3+ week, 3+ hour ago (1239+ words) Researchers found that ultrathin ruthenium dioxide can show spin behavior linked to altermagnetism, opening paths for future electronics. (CREDIT: Shutterstock) A material at the center of a major physics debate may have revealed its hidden magnetic side. Researchers at Rice…...
Laser-heated electrons can reshape metals in a billionth of a second
1+ mon, 1+ day ago (971+ words) Graphical representation of “hot electrons”. Electronic entropy phase transitions could rapidly change metal crystal structures before laser-heated atoms become hot. (CREDIT: Dr Sam Azadi) A metal struck by a powerful laser can enter a strange split state. Its electrons become…...
New process extracts 90% of the oil locked in waste coffee grounds - producing clean bio-diesel
1+ mon, 4+ day ago (1024+ words) Coffee grounds biodiesel could become cleaner and more efficient through a one-hour oil extraction process that preserves useful biomass. (CREDIT: Wikimedia / CC BY-SA 4.0) Coffee grounds carry more energy than their trip to the trash suggests. Packed with oils and plant…...
New hydrogel could transform wearable medical devices
1+ mon, 2+ week ago (1188+ words) Researchers at MIT created a new kind of hydrogel, a soft, water-rich material that behaves much like conventional hydrogels but also allows air to move through it. (CREDIT: Felice Frankel) A medical patch is supposed to protect skin, not suffocate…...
Physicists discover the upper limit of electrical resistance in metals
2+ mon, 1+ week ago (995+ words) Ultracold potassium atoms reveal that collision-driven resistivity can saturate, clarifying a long-running puzzle in transport physics. (CREDIT: AI-generated image / The Brighter Side of News) Electrical resistance is easy to notice and hard to pin down. Power lines shed energy as…...
The astonishing amount of energy locked inside ordinary matter
3+ mon, 1+ week ago (1490+ words) Ordinary matter looks solid and calm, but atomic nuclei hold immense energy locked behind powerful forces. (CREDIT: Wikimedia / CC BY-SA 4.0) Matter looks calm and solid, but its atoms hold immense energy locked inside tiny nuclei. That hidden reserve rarely escapes…...
Researchers turn sunlight and CO2 into living biomass
3+ mon, 1+ week ago (1341+ words) Researchers developed a semiartificial leaf that uses sunlight, carbon dioxide and engineered bacteria to grow living biomass. (CREDIT: Shutterstock) Carbon dioxide has long looked more like waste than resource. A new solar reactor turns it into living bacterial biomass using…...
New type of stainless steel pulls hydrogen directly out of seawater
3+ mon, 2+ week ago (1190+ words) New stainless steel from Hong Kong could make green hydrogen cheaper by replacing costly, corrosion-resistant materials. (CREDIT: Hong Kong University (HKU)) Green hydrogen has long been sold as one of the clean energy economy’s most important tools. It can be…...
