Simple method of binding pollutants in water with nanoadsorbers

New types of membrane adsorbers remove unwanted particles from water and also, at the same time, dissolved substances such as the hormonally active bis-phenol A or toxic lead. To do this, researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB imbed selective adsorber particles in filtration membranes. It was not until...

The first observation of the effect of electron spin of molecular oxygen on the surface oxidation reaction

Mitsunori Kurahashi, a Chief Researcher of the Nano Characterization Unit (Unit Director: Daisuke Fujita), National Institute for Materials Science (President: Sukekatsu Ushioda) and Yasushi Yamauchi, a Group Leader in the same unit, presented the first spin-controlled O2 adsorption experiment indicating that the rate of surface oxidation is strongly...

Gold nanoparticles size up to cancer treatment

Treatments that attack cancer cells through the targeted silencing of cancer genes could be developed using small interfering RNA molecules (siRNA). However delivering the siRNA into the cells intact is a challenge as it is readily degraded by enzymes in the blood and small enough to be eliminated from the blood stream by kidney filtration. Now Kazunori...
