3+ hour, 54+ min ago   (236+ words) Technology Org Most batteries spend more than 70% of their lifetime at rest. Yet few studies have examined calendar aging, which is how a battery degrades when it is neither charging nor being used. Now, a pair of complementary papers published…...

2+ week, 5+ day ago   (454+ words) For Hugh Smith, the challenge of building an energy-secure future isn’t about creating the world’s “best” battery. It’s about designing the right battery for the right job. “I’ve believed for a very long time that the biggest engineering problem humanity…...

3+ week, 4+ day ago   (690+ words) Barcode readers excel at quickly identifying groceries and other products. Could a similar idea work at industrial recycling facilities to make sorting different plastics quicker and more cost-effective? The answer, according to a University at Buffalo research team, is yes....

3+ week, 4+ day ago   (1067+ words) Chinese car manufacturers aren’t the only ones trying to develop new types of batteries. New materials are being tested in Norwegian laboratories to make batteries lighter, cheaper and more environmentally friendly. Lithium-ion batteries have revolutionized our lives since they first…...

3+ week, 5+ day ago   (238+ words) Metasurfaces are ultrathin optical components engineered with arrays of nanoscale structures that can control light in ways that are difficult for conventional optics. Unlike traditional optical components, which typically rely on their shape and thickness, metasurfaces manipulate light using carefully…...

1+ mon, 2+ week ago   (386+ words) Chemists at Brown University have shown the first experimental evidence that carbon buckyballs, which launched the nanotechnology revolution, have a cousin made from 80 atoms of the element boron. The nanoscale world appears to have a new ball to kick around....

1+ mon, 2+ week ago   (299+ words) In a study published in Science, researchers used silver nanoparticles to assemble a theorized, but never-before observed crystal metallic structure. Using finely tuned nanoscale building blocks, researchers from Brown University and the University of Michigan College of Engineering have stabilized…...

1+ mon, 2+ week ago   (856+ words) Hydrogels are squishy, bio-friendly materials that are made mostly of water and a bit of polymer. The Jell-O-like substance is available in the form of medical patches, sprays, and glues, and can be stuck to the skin or implanted in…...

2+ mon, 4+ week ago   (485+ words) Published in Nature Communications, the study uncovers a series of hidden intermediate stages that appear when molecules are heated to become materials. Capturing these intermediates opens a new way to discover and design materials that aren’t accessible through typical synthetic…...

2+ mon, 2+ week ago   (555+ words) With help from a novel cross-linking molecule, MIT chemists have shown they can substantially improve the ballistic impact resistance of common polymers, including polystyrene and a type of rubber used to make shoe soles. To make the polymer more resistant…...
