    Cause of cathode degradation identified for nickel-rich materials

    A team of scientists including researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and SLAC National Accelerator Laboratory have identified the causes of degradation in a cathode material for lithium-ion batteries, as well as possible remedies. Their findings, published on Mar. 7 in Advanced Functional Materials, could lead to the development of more affordable and better performing batteries for electric vehicles. …read more

    Nature-inspired antibacterial metals

    From aviation to medicine, various sectors are increasingly using materials that mimic the lotus plant, whose leaves have self-cleaning properties. Thanks to the bumpy surface structure covered with tube-shaped wax crystals, water falling on these leaves forms beads that roll off, carrying away dust and dirt. Using this naturally occurring lotus effect concept, a team of scientists has taken a quantum leap towards the production of self-cleaning sheet metal on an industrial scale. Supported by the EU-funded TresClean project, the team created a roughened surface on the metal that reduces wettability and prevents bacterial adhesion. …read more

    Wafer-scale multilayer fabrication of silk fibroin-based microelectronics

    A KAIST research team developed a novel fabrication method for the multilayer processing of silk-based microelectronics. This technology for creating a biodegradable silk fibroin film allows microfabrication with polymer or metal structures manufactured from photolithography. It can be a key technology in the implementation of silk fibroin-based biodegradable electronic devices or localized drug delivery through silk fibroin patterns. …read more

    Nanocoating makes lightweight metal foams bone-hard and explosion-proof

    Metallic foams developed by materials scientists Stefan Diebels and Anne Jung at Saarland University Strong are strong enough for use in impact protection systems in cars, and are able to absorb the shock waves produced by a detonation. Their super lightweight, extremely strong metal foams can be customized for a wide range of applications. …read more

    Video: Are we running out of helium?

    Did you realize that just like certain animals here on Earth, there are endangered elements, too? For example, we’re constantly losing helium, a gas that defies gravity and escapes our atmosphere into space. This incredible element is in high demand all over the globe. It’s also way too expensive to create in the laboratory, and that’s bad news for more than just your birthday party! …read more

    Engineering living ‘scaffolds’ for building materials

    When the inside of a mollusk shell shimmers in sunlight, the iridescence isn’t produced by colored pigments but by tiny physical structures self-assembled from living cells and inorganic components. Now, a team of researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a platform to mimic this self-assembly ability by engineering living cells to act as a starting point for building composite materials. …read more
