Disorder creates rust protection
Corrosion eats away 75 billion euros of economic output annually in Germany alone. But it may soon be possible to better assess which steels and other alloys will be affected, and how to limit the damage: ...
New measuring techniques can improve efficiency, safety of nanoparticles
Using high-precision microscopy and X-ray scattering techniques, University of Oregon researchers have gained eye-opening insights into the process of applying green chemistry to nanotechnology that results in high yields, ...
Artificial muscle contracts and expands with changes in humidity
(Phys.org) —A small plastic strip can do "weight training" to effortlessly lifts many times its own weight, driven by cyclic changes in the humidity of the surrounding air. This strong "artificial arm" is based on the interaction ...
Researchers find treating pavement with titanium oxide reduces air pollution
Nanoparticles and their size may not be big issues
If you've ever eaten from silverware or worn copper jewelry, you've been in a perfect storm in which nanoparticles were dropped into the environment, say scientists at the University of Oregon.
Safety agency to push for national air bag recall (Update)
