Transforming ‘noise’ into mechanical energy at nanometric level

A team of researchers at the Freie Universität Berlin, co-ordinated by José Ignacio Pascual (current leader of the Nanoimagen team at CIC nanoGUNE), have developed a method that enables efficiently using the random movement of a molecule in order to make a macroscopic-scale lever oscillate. The research was published in Science.

Research Reveals Nanotechnology Simplifies Hydrogen Production for Clean Energy

In the first-ever experiment of its kind, researchers have demonstrated that clean energy hydrogen can be produced from water splitting by using very small metal particles that are exposed to sunlight. In the article, "Outstanding activity of sub-nm Au clusters for photocatalytic hydrogen production," published in the journal Applied Catalysis B: Environmental, Alexander Orlov, PhD, an Assistant Professor of Materials Science & Engineering at Stony Brook University, and his colleagues from Stony Brook and Brookhaven National Laboratory, found that the use of gold particles smaller than one nanometer resulted in greater hydrogen production than other co-catalysts tested.

King's College London finds rainbows on nanoscale: Big impact on solar cells, television screens

New research at King's College London may lead to improved solar cells and LED-displays. Researchers from the Biophysics and Nanotechnology Group at King's, led by Professor Anatoly Zayats in the department of Physics have demonstrated in detail how to separate colours and create 'rainbows' using nanoscale structures on a metal surface. The research is published in Nature's Scientific Reports.

So BRIGHT, you need to wear shades: Tiny probes shine brightly to reveal the location of targeted tissues

Called BRIGHTs, the tiny probes described in the online issue of Advanced Materials on Nov. 15, bind to biomarkers of disease and, when swept by an infrared laser, light up to reveal their location.

Nanostructures called BRIGHTs seek out biomarkers on cells and then beam brightly to reveal their locations. In the tiny gap between the gold skin and the gold core of the cleaved BRIGHT (visible to the upper left), there is an electromagnetic hot spot that lights up the reporter molecules trapped there.
