New hybrid carbon material, which combines both graphene and SWNTs, Graphene Nanoribbons encapsulated into Single-Walled Carbon Nanotubes (GNR@SWNTs) have been discovered by researchers from Aalto University (Finland) and Umea University.
Researchers used a combination of four techniques to make the first detailed images of nitrogen-doped graphene film. They showed that individual nitrogen atoms had taken the places of carbon atoms in the two-dimensional sheet; that about half of the extra electron contributed by each nitrogen atom was distributed throughout the graphene lattice; and that this changed the electronic structure of the graphene sheet only within a short distance - about the width of two carbon atoms - from the dopant atoms.
With the aim of continuing to promote industrial innovation based on state-of-the-art technologies, CSEM has opened a new innovation center in Muttenz, with the support of the Canton of Basel-Landschaft. The polytronics development center is involved in the mass production of organic electronics.
As part of the research programmes, CRANN will assist Merck Millipore to further develop the nanostructures of their products' artificial membranes, that are widely used for medical and diagnostic devices, and to deliver new products with improved membrane performances.
Researchers under ETH-Zurich professor Colombo Bolognesi are working on a new gallium nitride transistor technology using silicon(110) as a substrate. As the new combination of materials has many advantages, gallium nitride is poised to conquer the electronics market and help power the green revolution.
Researchers have succeeded in dramatically increasing the energy density of supercapacitors, which are used to store electrical energy. This was realized by developing a new electrode in which graphene nanosheets are stacked in a layered structure with carbon nanotubes sandwiched between the graphene layers.
The Singapore Institute of Manufacturing Technology (SIMTech), a research institute of the Agency for Science, Technology and Research (A*STAR), launched the SIMTech Microfluidics Foundry (SMF) today. SMF offers an integrated spectrum of capabilities for developing and manufacturing of specialised and low-cost microfluidic devices for applications in healthcare, biomedical, pharmaceutical, energy, water quality monitoring and chemical processing.
Assembly of nanostructures using DNA may lead to the production of new materials with a wide range of applications from electronics to tissue engineering. Researchers in the Institute for Nanoscience and Engineering at the University of Arkansas have produced building blocks for such material by controlling the number, placement and orientation of DNA linkers on the surface of colloidal nanoparticles.
Human devices, from light bulbs to iPods, send information using electrons. Human bodies and all other living things, on the other hand, send signals and perform work using ions or protons. Materials scientists at the University of Washington have built a novel transistor that uses protons, creating a key piece for devices that can communicate directly with living things.
