It is evident from samples from mammoths, bears, and other fossils: sequenceable DNA can last up to several hundred thousand years. But one does not necessarily need fossil bones as capsules of silica glass spheres can do the same job.
With properties that promise faster computers, better sensors and much more, graphene has been dubbed the 'miracle material'. But progress in producing it on an industrial scale without compromising its properties has proved elusive. University of Groningen scientists may now have made a breakthrough.
Researchers have designed and developed hybrid gold-silica nanoparticles, which are turning out to be genuine therapeutic 'Swiss Army knives'. Tested in mice and on cultured human cells, they make it possible to combine two forms of tumor treatment and three imaging techniques.
The efficiency of plastic solar cells can be doubled or tripled if an extra solvent is added during the production process, comparable with the role of baking powder in dough mixture. Exactly how this works has been unclear for the last ten years.
