Hydrogels are materials that are commonly used in everyday objects such as contact lenses or diapers, in order to control humidity.
A novel approach to growing nanowires promises a new means of control over their light-emitting and electronic properties. In a recent issue of Nano Letters, scientists from the U.S. Department of Energy’s Lawrence Berkeley National Lab (Berkeley Lab) demonstrated a new growth technique that uses specially engineered catalysts.
Anyone who has ever toasted the top of their legs with their laptop or broiled their ear on a cell phone knows that microelectronic devices can give off a lot of heat. These devices contain a multitude of transistors, and although each one produces very little heat individually, their combined thermal output is significant and can damage the device.
Today, Hanergy Thin Film Power Group Ltd. held a mobile energy strategy presentation and the launch ceremony of its global thin-film solar product innovation competition. Mobile energy, as envisioned by Hanergy, is a novel concept and strategic judgment based on the global energy development trend.
Supporting Governor Andrew Cuomo’s high-tech educational paradigm for New York’s students, 300 middle and high school students visited SUNY Polytechnic Institute’s Colleges of Nanoscale Science and Engineering (SUNY Poly CNSE) on Thursday, February 5, to take part in an exciting “NanoCareer Day” program.
Light and matter can be so strongly linked that their characteristics become indistinguishable. These light-matter couplings are referred to as polaritons. Their energy oscillates continuously between both systems, giving rise to attractive new physical phenomena.
The joint research group led by Takuzo Aida, director, Emergent Soft Matter Function Research Group, Center for Emergent Matter Science, RIKEN (also a professor at the School of Engineering, University of Tokyo), Yasuhiro Ishida, leader, Emergent Bioinspired Soft Matter Research Team, RIKEN, and Takayoshi Sasaki, fellow, International Center for Materials Nanoarchitectonics, NIMS, successfully developed a material that expresses a unique mechanical property by arranging oxide nanosheets, that electrostatically repel each other, in the direction perpendicular to a magnetic field, and by confining a three-dimensional nano-network structure in a water-swollen gel material, hydrogel.
Researchers at The University of Texas at Austin's Cockrell School of Engineering have created the first transistors made of silicene, the world’s thinnest silicon material. Their research holds the promise of building dramatically faster, smaller and more efficient computer chips.
Graphene has many potential applications, among them energy generation, conversion and storage. Graphene – a single layer of carbon atoms – and related two-dimensional crystals combine high electrical conductivity with physical flexibility and a huge surface to weight ratio. Such qualities make them suitable for storing electric charge in batteries and supercapacitors, and as catalysts in solar and fuel-cell electrodes.
Scientists from Rice University and Shandong University, China, celebrated the opening of the Joint Center for Carbon Nanomaterials, a collaborative facility to study nanotechnology, on Feb. 1.
