Applied Nanotech Holdings, Inc. announced that Solexel (www.solexel.com) presented its world record achievement of 20.62% efficiency from 156 mm x 156 mm full-square solar cell using its low cost ultra thin epitaxial silicon film and porous silicon lift-off technology at PV Asia Pacific (APVIA/PVAP) Expo 2012 in Singapore on October 24, 2012. This record thin-silicon efficiency was achieved by Solexel's unique epitaxial cell architecture and proprietary manufacturing process flow, utilizing Applied Nanotech's proprietary aluminum metallization material.
Many industrial plants depend on water vapor condensing on metal plates: In power plants, the resulting water is then returned to a boiler to be vaporized again; in desalination plants, it yields a supply of clean water. The efficiency of such plants depends crucially on how easily droplets of water can form on these metal plates, or condensers, and how easily they fall away, leaving room for more droplets to form.
Plasmonic gold nanoparticles make pinpoint heating on demand possible. Now Rice University researchers have found a way to selectively heat diverse nanoparticles that could advance their use in medicine and industry.
Following on from the success of the first training school held in March 2012, the next Modelling Training School funded under FP7 project QNano will take place on the 27th March 2013 at the Edinburgh Training & Conference Venue (ETCV), St. Mary’s Street, Edinburgh, UK.
As Twelfth Night approaches and the Christmas decorations start to look increasingly congruous as the last crumbs of cake are swept away and the remnants of the turkey have finally been consumed, there is the perennial question as to what to do with the tree. Research published in the International Journal of Biomedical Nanoscience and Nanotechnology suggests that the needles of the plant Pseudotsuga menziesii, commonly known as the Douglas fir could be used to sterilize nano devices destined for medical applications.
Certain plants and animals protect themselves against temperatures below freezing with antifreeze proteins. How the larva of the beetle Dendroides canadensis manages to withstand temperatures down to -30 degrees Celsius is reported by an international team of researchers led by Prof. Dr. Martina Havenith from the Department of Physical Chemistry II at the Ruhr-Universität in the journal PNAS. Together with American colleagues, the RUB-researchers showed that interactions between the antifreeze proteins and water molecules contribute significantly to protection against the cold. Previously, it was assumed that the effect was only achieved through direct contact of the protein with ice crystals. The team obtained the results through a combination of terahertz spectroscopy and molecular dynamics simulations.
Imagine for a moment a world were automotive plastics never fade, a self-cleaning wheel that resists brake dust, a self-cleaning tire that looks new for life, or a fiberglass boat that resists fading for life. These and other amazing benefits are now possible due to 10 years of research & development in nanotechnology.
Directed assembly is a growing field of research in nanotechnology in which scientists and engineers aim to manufacture structures on the smallest scales without having to individually manipulate each component. Rather, they set out precisely defined starting conditions and let the physics and chemistry that govern those components do the rest.
The first workshop organised by Oxford Instruments Plasma Technology at MIT’s Microsystems Technology Laboratories (MTL), Cambridge, MA in December was attended by a wide audience, and hailed a great success. It addressed the latest research and technologies in plasma etch and deposition, via technical presentations and discussions focussing on latest innovations, as well as a networking lunch.
Aiming to address the strategic military need for accurate, high-resolution imaging, a University of Wisconsin-Madison electrical and computer engineer working with the U.S. Air Force Office of Scientific Research and the U.S. Department of Defense has a simple goal: to make night vision more accurate and easier for soldiers and pilots to use.
