New insights on controlling nanoparticle stability

New findings could enhance stabilizing or destabilizing nanoparticles, depending on their uses

11-12-2013

University of Oregon chemists studying the structure of ligand-stabilized gold nanoparticles have captured fundamental new insights about their stability. The information, they say, could help to maintain a desired, integral property in nanoparticles used in electronic devices, where stability is ...

Nanodiamonds in ambient conditions

23-10-2013

Instead of having to use tons of crushing force and volcanic heat to forge diamonds, researchers at Case Western Reserve University have developed a way to cheaply make nanodiamonds on a lab bench at atmospheric pressure and near room temperature. The nanodiamonds are formed directly from a gas ...

Sticking power of plant polyphenols used in new coatings

Compounds found in red wine and green tea stick to anything, retain useful properties

26-08-2013

A simple kitchen sink experiment helped Northwestern University researchers discover that green tea leaves not only can be used to steep a good cup of tea, but they make an excellent antibacterial coating, too. And so can red wine, dark chocolate and cacao beans, they found. It's the powerful and ...

'Self-cleaning' pollution-control technology could do more harm than good

17-06-2013

Research by Indiana University environmental scientists shows that air-pollution-removal technology used in "self-cleaning" paints and building surfaces may actually cause more problems than they solve. The study finds that titanium dioxide coatings, seen as promising for their role in breaking ...
