In a report today at the 238th National Meeting of the American Chemical Society, scientists describe development of a test for performance of smudge- and reflection-resistant coatings and its use to determine how to improve that performance.
Friends of the Earth, Consumers Union, and the International Center for Technology Assessment (ICTA) released a report today detailing why consumers should be wary of sunscreens that contain nanomaterials.
Using thin films of silk as templates, researchers have incorporated inorganic nanoparticles that join with the silk to form strong and flexible composite structures that have unusual optical and mechanical properties.
After engineers and scientists at Virginia Tech, Harvard and Drexel finish studying the locomotion of fish in water, Michael Phelps may find he still has a few new ways to increase his own world-breaking Olympic times.
Good news for people fearful of needles and squeamish of shots: Scientists report the design of a painless patch that may someday render hypodermic needles - as well as annual flu shots - a thing of the past.
In a presentation today to the American Chemical Society meeting, Ankit Agarwal, a postdoctoral researcher at the University of Wisconsin-Madison, described an experimental approach to wound healing that could take advantage of silver's anti-bacterial properties, while sidestepping the damage silver can cause to cells needed for healing.
Wissenschaftlern des Max-Planck-Institutes fuer Kolloid- und Grenzflaechenforschung in Potsdam-Golm, der Jacobs University Bremen und der Queen Mary University London ist es erstmals gelungen stoffwechselresistente Mikrokapseln in lebende Zellen einzuschleusen und deren Inhalt durch Laserimpuls mit exakter zeitlicher Kontrolle freizusetzen.
A study published in the forthcoming issue of the European Respiratory Journal (ERJ), has for the first time claimed a concrete link between exposure to nanoparticles in adhesive paint and development of severe pulmonary fibrosis in a group of young female workers; two of whom went on to suffer fatal lung failure.
Naturally occurring organic matter in water and sediment appears to play a key role in helping microbes convert tiny particles of mercury in the environment into a form that is dangerous to most living creatures.
