When most living creatures get hurt, they can self-heal and recover from the injury. But, when damage occurs to inanimate objects, they don't have that same ability and typically either lose functionality or have their useful lifecycle reduced. Researchers are working to change that.
Scientists have discovered half-quantum vortices in superfluid helium. This vortex is a topological defect, exhibited in superfluids and superconductors, which carries a fixed amount of circulating current.
Our bodies contain Natural Killer (cells - an army that stops cancers and viruses before they can make us sick. A researcher has created a nanoparticle that increases the number of these killers 10,000-fold in the lab and her new technology has generated a licensing agreement that is expected to accelerate the therapy's path to clinical trials.
A newly funded project plans to gain new insights into the catalytic abilities of nanoparticles, particularly how the size, shape and chemical state of the particles change during a catalytic reaction.
A team of engineers has developed a new method for creating entire device arrays directly on the copper substrates used for the commercial manufacture of graphene. Complete and fully-functional devices can then be transferred to a substrate of choice, such as silicon, plastics or even textiles.
Scientists have developed a new type anode material that would be used in place of a conventional graphite anode, which they claim will lead to lighter and longer-lasting batteries for everything from personal devices to electric vehicles.
