Unlike various visions of hologram application described in sci-fi tales, currently used technology used to show holograms usually allows projection of a red or blue stereoscopic. Notable progress in nanotechnology in recent years led to advances research on surface plasmons which allowed a group of researchers from RIKEN institute to develop a novel holography principle… »

In order to check their glucose levels, diabetics usually have to draw blood. In order to eliminate the need for this invasive way of glucose level control, engineers at Brown University have designed a biological device that can measure glucose concentrations in human saliva. The technique takes advantage of a convergence of nanotechnology and surface… »

Researchers from the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have unveiled a semiconductor nanocrystal coating material capable to control the amount of solar heat while remaining transparent. The technology is the first to selectively control the amount of near infrared radiation and it is based on electrochromic materials (which use… »

A multidisciplinary team of Stanford engineers led by Mike McGehee, Yi Cui and Mark Brongersma, and joined by Michael Graetzel at the École Polytechnique Fédérale de Lausanne (EPFL), is developing a new type of thin solar cell that could offer a new direction for the field. They succeeded in harnessing plasmonics – trapping light within… »
