Preventing dental implant infections with silver nanoparticles

One million dental implants are inserted every year in Germany, and often they need to be replaced due to issues such as tissue infections caused by bacteria. In the future, these infections will be prevented thanks to a new plasma implant coating that kills pathogens using silver ions.

New design using graphene points a path to the 'ultimate' battery

Scientists have developed a working laboratory demonstrator of a lithium-oxygen battery which has very high energy density, is more than 90% efficient, and, to date, can be recharged more than 2000 times, showing how several of the problems holding back the development of these devices could be solved.

A new study and a project to investigate bioinspired materials

Being all in one piece is not always a good strategy for resisting external strain. Biological tissues are well aware of it: they tend to crack simultaneously and gradually in several places, rather than catastrophically in one place only. This makes them particularly resistant. Researchers conducted a theoretical study that explains the mechanism underlying this phenomenon, which was experimentally observed in epithelial cell cultures.
