Magnets trump metallics: Magnetic fields can block conductivity of carbon nanotubes
Metallic carbon nanotubes show great promise for applications from microelectronics to power lines because of their ballistic transmission of electrons. But who knew magnets could stop those electrons in their ...
Graphene 2.0: A new approach to making a unique material
Since its discovery, graphene -- an unusual and versatile substance composed of a single-layer crystal lattice of carbon atoms—has caused much excitement in the scientific community. Now, Nongjian(NJ) Tao, ...
Graphane yields new potential: Physicists dig theoretical wells to mine quantum dots
Graphane is the material of choice for physicists on the cutting edge of materials science, and Rice University researchers are right there with the pack - and perhaps a little ahead.
New PV cell generates electricity from IR and UV light
New alloys key to efficient energy and lighting
A recent advance by Arizona State University researchers in developing nanowires could lead to more efficient photovoltaic cells for generating energy from sunlight, and to better light-emitting diodes (LEDs) that could replace ...
Researchers make graphene hybrid
Rice University researchers have found a way to stitch graphene and hexagonal boron nitride (h-BN) into a two-dimensional quilt that offers new paths of exploration for materials scientists.
New graphene 'nanomesh' could change the future of electronics
(PhysOrg.com) -- Graphene, a one-atom-thick layer of a carbon lattice with a honeycomb structure, has great potential for use in radios, computers, phones and other electronic devices. But applications have been stymied because ...
