Samuel Lara-Avila has been awarded the Arne Sjögren prize for most innovative PhD thesis in the area of Nanoscience and Nanotechnology at Chalmers in 2012, for his thesis 'Magnetotransport characterization of epitaxial graphene on SiC'.
The Nanotechnology Knowledge Transfer Network, one of the UK's primary knowledge-based networks for Micro and Nanotechnologies, announced the availability of its free 2013 version of the UK Nanotechnology Health, Safety and Environment Directory.
Using a spin-polarized metastable helium beam, a research group of the Japan Atomic Energy Agency (JAEA) and the National Institute for Materials Science (NIMS) succeeded in detecting the electronic spin state of only the graphene contacted to a magnetic metal in devices.
A process combining some comparatively cheap materials and the same antifreeze that keeps an automobile radiator from freezing in cold weather may be the key to making solar cells that cost less and avoid toxic compounds, while further expanding the use of solar energy.
Researchers achieved a new world record in the energy efficient integration in silicon. They optimized aperiodic grating couplers in the nanometer range with a new developed backside metal mirror. Through this new method a record coupling efficiency of 87 percent between optical fibers and photonic integrated waveguides on silicon wafers has been achieved.
The foundation of many, many modern electronic devices - including computers, smart phones, and televisions - is the silicon transistor. However, the shrinking of consumer electronics is driving researchers to investigate materials that can yield thinner transistors. Researchers have used x-rays to probe the electronic behavior of a germanium-based transistor structure, yielding important information that will guide future studies of how to make transistors smaller.
Researchers describe a pair of tweezers shrunk down to an astonishingly tiny scale. The group demonstrated that the nanotweezers, fabricated by means of the base-pairing properties of DNA, could be used to keep biological molecules spatially separated or to bring them together as chemical reactants, depending on the open or closed state of the tweezers.
In 1998, the Nobel Prize in Physics was conferred to the discovery of a new type of quantum fluid with fractional charge excitations, known as Laughlin state. Now, theoretical research proposes a method to generate this kind of states in two-dimensional systems of ultracold atoms, with possible applications in quantum computer.
