Water drops can unleash tiny electrical discharges that trigger corrosion
8+ hour, 40+ min ago (1008+ words) Electrically charged water droplets can puncture protective coatings, exposing the metal beneath and creating new pathways for corrosion. Protective coatings help bridges, ships, cars, buildings, and outdoor objects resist corrosion. Corrosion is a slow chemical process that damages metal and…...
Carbon dioxide can be recycled into everyday chemicals with help from a blender
4+ day, 11+ hour ago (911+ words) Scientists found a way to mass-produce a low-cost catalyst that turns captured carbon dioxide into chemicals used in fuels, plastics and medicines. Turning captured carbon dioxide from power plants and factories into useful chemicals has struggled to make economic sense....
Cement production could someday replace fossil-fuel flames with electricity
4+ day, 15+ hour ago (974+ words) A new electric plasma process makes cement in seconds, uses heat more efficiently, and could reduce emissions from cement production. Cement is in the sidewalk outside your door, the foundation under your house, and nearly every bridge you drive over....
Chemists have turned a hard-to-recycle plastic into valuable oil
1+ week, 3+ day ago (1188+ words) A new chemical process gives PVC waste a surprising second life, turning everyday plastic products into a potentially valuable material. A pipe under a kitchen sink and the credit card that pays for groceries are made of the same type…...
Scientists turn plastic bottle waste into vanilla-scented cookies
1+ week, 4+ day ago (968+ words) using engineered yeast and 3D printing. A discarded water bottle and a pile of corn stalks sound like the last things anyone would put near a cookie tray. Yet researchers have used their carbon-rich components to create a protein-rich, vanilla-scented food…...
Toxic chemicals from old products are still spreading across Europe
2+ week, 8+ hour ago (921+ words) Flame retardants banned across Europe decades ago are still turning up in the environment, from industrial areas to remote Arctic and alpine regions. Some chemicals do not disappear after governments ban them. A sweeping new review found that flame retardants…...
Physicists photograph a state of matter that is solid and liquid at once
2+ week, 2+ day ago (823+ words) Physicists in Barcelona captured the first direct images of a supersolid, a quantum state of matter that flows like a liquid while holding a crystal pattern. In this quantum state, atoms hold the rigid, repeating pattern of a crystal. At…...
Cement plants could pull more carbon from the air than they release
3+ week, 3+ day ago (918+ words) Cement plants could become carbon-negative by combining electric kilns with direct air capture to pull CO2 from the atmosphere. Cement is in nearly every sidewalk, foundation, and highway overpass on Earth. Making it means heating limestone until it breaks apart. That…...
German invention converts one-third of direct sunlight into hydrogen
1+ mon, 2+ day ago (845+ words) Scientists in Germany have built a compact device that converted up to 31.3 percent of incoming sunlight into chemical energy stored as hydrogen during outdoor testing. Put simply, that is almost one-third of the sunlight reaching the device. The researchers say…...
Forever chemicals may finally have a way out of the bloodstream
1+ mon, 5+ day ago (1281+ words) The machine is not new. For decades it has drawn blood from one arm, stripped the cholesterol out, and sent it back. What is new is what else came out: forever chemicals in the blood. Nearly everyone alive carries forever…...
