A novel approach to Density Functional Theory

hydrogen_moleculeIn the past decades, the Density Functional Theory (DFT) has been very successful in helping chemists and physicists understand the properties of matter at extremely small scales. Although some problems still remain in the standard implementation of DFT, it represents an important theoretical tool which is used on a daily basis. Scientists now propose a variant of the standard DFT which could pave the way towards the simulation of very complex chemical and physical systems at a quantum level.

Anti-icing strategies inspired by nanotechnology and biology

iceIce accumulation is not just a cost and safety problem for the airline industry and other transportation areas, together with undesired environmental impacts. Here are some examples: Transmission lines and power network towers may deform or even collapse with the burden of excess amount of ice; ice accretion on wind turbine blades can cause a production loss as much as 50% of the annual production; frost and ice accumulation in refrigerators and heat exchangers results in a decrease of heat transfer efficiency. Therefore, great efforts have been made to understand the mechanism of icing and investigations on anti-icing and deicing have been extensively carried out. Various anti-icing and deicing methods have been developed such as for instance nanocoatings and other nanostructured surfaces.

A Google Glass app for instant medical diagnostics (w/video)

Google_GlassThe integration of consumer electronics with advanced imaging and analytical platforms holds great promises for medical point-of-care diagnostics and environmental rapid field testing for pollutants and viruses. A recent example is a Google Glass application and a server platform for instant, wireless diagnostic testing of a variety of health conditions and diseases. This technology allows Google Glass wearers to use the hands-free camera on the device to send images of diagnostic tests that screen for conditions such as HIV or prostate cancer.

Nanotechnology for disaster relief and development cooperation

disaster_reliefIn the area of development cooperation which, like disaster relief, is often confronted with demands and scenarios that are hard to predict, nanotechnology based solutions can offer interesting perspectives for medical care, water treatment, agriculture and food, as well as rural infrastructure development in developing countries. A publication aims to inform managers and staff working in emergency response services and development cooperation as well as related institutions about the innovation potential of nanotechnology for their respective fields of work, and to highlight areas of overlap. The 84-page brochure also addresses companies and industry representatives that are already operating in this area or are interested in tapping in to this market.

Superlubricity on the macroscale

carbon_nanotubeFriction is present in numerous physical phenomena occurring at all length scale. About 1/3 of the world's primary energy is dissipated in mechanical friction and 80% of machinery components' failure is caused by wear. Friction and wear will also become bottlenecks for micro-/nano-mechanical systems (MEMS and NEMS) featured with sliding components. Superlubricity, a phenomenon where the friction almost vanishes between two solid surfaces, will be the key to solve these problems and researchers now report a breakthrough in macroscale superlubricity.

Artificial intelligence (AI) in nanotechnology research

artificial_intelligenceWhile nanotechnology combines the knowledge of physics, chemistry and engineering, AI has heavily relied on biological inspiration to develop some of its most effective paradigms such as neural networks or evolutionary algorithms. Bridging the link between current nanosciences and AI can boost research in these disciplines and provide a new generation of information and communication technologies that will have a large impact in our society, probably providing the means so that technology and biology merge

Covetics - Rare new hybrid fuses nanocarbons and metal in bond stronger than sp2

latticeCovetics - this new class of materials marks a game-changer for engineers and designers that have long sought to combine high-strength carbon with metal in their pursuit to improve metal's performance. For the first time the hybrid fuses nanocarbons and metal in a bond that is stronger than graphene-like sp2 carbon bonds. To create covetics, its inventors developed a new method of carbon catalyzation which uses molten metal and metal alloys as an ionizing medium. Nanocarbon structures form in situ while bonding to the metal ionizing medium.
