'Ion billiards' cue novel material synthesis method

21-Nov-2017 - A team of Hokkaido University researchers has developed a novel material synthesis method called proton-driven ion introduction (PDII) which utilizes a phenomenon similar to "ion billiards." The new method could pave the way for creating numerous new materials, thus drastically advancing ...

Core technology springs from nanoscale rods

13-Oct-2016 - Rice University scientists have discovered how to subtly change the interior structure of semi-hollow nanorods in a way that alters how they interact with light, and because the changes are reversible, the method could form the basis of a nanoscale switch with enormous potential. "It's not 0-1, ...

09-Jul-2010 - Empa researchers have demonstrated how they can adjust process conditions to influence the properties of novel plasma polymer coatings containing silver nanoparticles. Tailor-made films can be generated through a one-step plasma process. The scientists developed these new coatings, which kill ...

Nanosilver has no place in food, textiles or cosmetics

BfR currently advises against using nanoscale silver ions in consumer products

11-Jun-2010 - The manufacturers of consumer products have made use of the antimicrobial properties of silver ions for some time now. Recently, silver particles in the nanorange have likewise been used. For instance, the surfaces in fridges coated with nanosilver are intended to inhibit the growth of germs and ...

The toxicity of antimicrobial silver in products can be reduced

26-Feb-2010 - Chemists at the University of Helsinki have managed to manufacture new polymer-stabilised silver nanoparticles. The result is significant because the antimicrobial characteristics of silver are used in textiles, floor coatings and paints even though the impact on health of silver nanoparticles ...
