Particular interest has been on semiconducting materials, such as molybdenum disulfide (MoS2), an abundant material in nature, which exhibits the unique physical, optical and electrical properties correlated with its single-layer atomic layer structure. Researchers have now fabricated a mechanically exfoliated single-layer MoS2 based phototransistor and investigated its electric characteristics in detail. These new findings show that, when compared with a 2D graphene-based device, the single-layer MoS2 phototransistor exhibits a better photoresponsivity. http://www.nanowerk.com/spotlight/spotid=24165.php http://www.nanowerk.com/news/newsid=24166.php The antennaless RFID tag developed at CNSE could help companies track products as varied as barrels of oil to metal cargo containers. http://www.nanowerk.com/news/newsid=24166.php http://www.nanowerk.com/news/newsid=24167.php A team of University of Bristol scientists explores whether new models or concepts are needed to tackle one of the 'grand challenges' of chemical biology: understanding enzyme catalysis. http://www.nanowerk.com/news/newsid=24167.php http://www.nanowerk.com/news/newsid=24168.php Polyera has achieved a certified world-record 9.1% efficient polymer/fullerene organic solar cell in an inverted bulk heterojunction architecture using its newest proprietary ActivInk PV2000 semiconductor material. http://www.nanowerk.com/news/newsid=24168.php http://www.nanowerk.com/news/newsid=24169.php Researchers have used graphene to develop a new composite material which can produce the toughest fibres to date - even tougher than spider silk and Kevlar. http://www.nanowerk.com/news/newsid=24169.php http://www.nanowerk.com/news/newsid=24151.php Researchers from the NIST Center for Nanoscale Science and Technology have made a grating coupler that transmits over 45 % of the incident optical energy from a plane wave into a single surface plasmon polariton (SPP) mode propagating on a flat gold surface, an order-of-magnitude increase over any SPP grating coupler reported to date. http://www.nanowerk.com/news/newsid=24151.php http://www.nanowerk.com/news/newsid=24152.php Engineers have developed a prototype device that could power a pacemaker using a source that is surprisingly close to the heart of the matter: vibrations in the chest cavity that are due mainly to heartbeats. http://www.nanowerk.com/news/newsid=24152.php http://www.nanowerk.com/news/newsid=24153.php Today sees the announcement of full details of how an additional GBP50 million will be spent to keep the UK at the forefront of research into 'wonder material' graphene.

The DNA nanostructure can also be equipped with specific docking sites for proteins. Researchers have now introduced a new method for attaching the proteins by means of special "adapters" known as zinc-finger proteins. http://www.nanowerk.com/news/newsid=24154.php http://www.nanowerk.com/spotlight/spotid=24155.php Back in the early 2010s, food nanotechnology seemed to be a very hot topic and large industrial food companies were eager to explore new opportunities offered by nanotechnology applications. Then, as critical voices from NGOs and regulators appeared, the food industry went into silent mode. But that doesn't mean that food nanotechnologies aren't being researched and developed in labs around the world. Here is an overview of what nanotechnology applications are currently being researched, tested and in some cases already applied in food technology. It appears that we are still some way from seeing "Frankenfoods" in supermarket shelves. According to a recent commentary by an FDA official, what's holding back the introduction of nanofoods is the hesitation of the food industry, fearing a public backlash along the lines of what happened wit genetically modified foods. http://www.nanowerk.com/spotlight/spotid=24155.php http://www.nanowerk.com/news/newsid=24156.php Using a self-assembled photosystem, researchers are turning the term 'power plant' on its head http://www.nanowerk.com/news/newsid=24156.php http://www.nanowerk.com/news/newsid=24157.php 2012 Knowledge Series to commemorate 25th anniversary. http://www.nanowerk.com/news/newsid=24157.php http://www.nanowerk.com/news/newsid=24158.php Grants will enable technologies targeting clean energy and the environment, nanomedicine and health care, and military applications. http://www.nanowerk.com/news/newsid=24158.php http://www.nanowerk.com/news/newsid=24159.php Cash prize and grant awarded during SPIE BiOS/Photonics West 2012 conference. http://www.nanowerk.com/news/newsid=24159.php http://www.nanowerk.com/news/newsid=24160.php An international consortium of scientists from The Netherlands, Sweden and Ukraine claim a breakthrough in the theory of ultrafast magnetic phenomena. http://www.nanowerk.com/news/newsid=24160.php http://www.nanowerk.com/news/newsid=24161.php A Manchester team lead by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research.
