Scientists at Rensselaer Polytechnic Institute are working to optimize a promising new nanomaterial called nanoblades for use in hydrogen storage. During their testing of the new material, they have discovered that it can store and release hydrogen extremely fast and at low temperatures compared to similar materials.
Wissenschaftlern der Johannes Gutenberg-Universitaet Mainz ist es gelungen, in die Struktur von Heusler-Materialien vorzudringen und das Verhalten der Elektronen zu beobachten. Sie verwenden dazu eine besondere Form der Photoelektronenspektroskopie, die es moeglich macht, viel tiefer als bisher in die Materie vorzudringen und die elektronische Beschaffenheit zu untersuchen.
Probably the leading team that is driving forward the work on nanogenerators for converting mechanical energy into electricity is Zhong Lin Wang's group at Georgia Tech has published a a comprehensive and coherent review about the development of nanogeneratos, organizing the book based on the group's published papers. And best of all, it is a free e-book.
A collaborative Oregon State University-University of Oregon Center for Sustainable Materials Chemistry, born under a National Science Foundation grant in 2008, is moving into a second phase under a new five-year, $20 million grant.
With the discovery of a RNA nano-scaffold that remains unusually stable in the body, researchers at the University of Cincinnati have overcome another barrier to the development of therapeutic RNA nanotechnology.
An international team of researchers has for the first time demonstrated that random, haphazardly grown silicon nanowires can significantly boost the power-producing capabilities of solar cells by trapping a broad spectrum of light waves and capturing sunlight streaming in from a wide variety of angles.
Researchers from the University of Notre Dame in Indiana have harnessed another one of graphene's remarkable properties to better control a relatively untamed portion of the electromagnetic spectrum: the terahertz band.
Engineers at the University of California, Berkeley, have shown that it is possible to reduce the minimum voltage necessary to store charge in a capacitor, an achievement that could reduce the power draw and heat generation of today's electronics.
A new $13-million National Science Foundation center based at the University of Michigan will develop high-tech materials that manipulate light in new ways. The research could enable advances such as invisibility cloaks, nanoscale lasers, high-efficiency lighting, and quantum computers.
By demonstrating for the first time a 40Gbit/s optical modulator in silicon with a record extinction ratio of 10dB (the power difference between the 1 and 0 data levels), members of the HELIOS Project accomplished one of the key project goals needed to build and optimize the entire supply chain for fabricating complex functional silicon- photonics devices from design to the process level.
Inspired by the Nobel Prize-winning research on the mechanical exfoliation of graphene using 'scotch tape', researchers have now devised a method for the separation of semiconducting and metallic CNTs without damaging them.
