Light-Emitting Nano Triangles May Have Applications in Optical Technology
February 5, 2013 — For the first time, scientists have created single layers of a naturally occurring rare mineral called tungstenite, which they have used to produce a sheet of stacked sulfur and tungsten atoms with ... > full story -
New Findings on the Structure of Graphite Oxides in Alcohols
February 5, 2013 — The structure of graphite oxide surprisingly expands when cooled in methanol or ethanol. Also, graphite oxide selectively absorbs methanol from water-methanol mixtures. Two new studies by physicists ... > full story -
Routes Towards Defect-Free Graphene
February 1, 2013 — A new way of growing graphene without the defects that weaken it and prevent electrons from flowing freely within it could open the way to large-scale manufacturing of graphene-based devices with ... > full story -
Flat Boron by the Numbers: Researchers Calculate What It Would Take to Make New Two-Dimensional Material
January 31, 2013 — Physicists detail several possible routes to the creation of two-dimensional sheets of boron. They say such sheets would be more conductive than graphene and thus useful in electronic ... > full story -
Giant Carbon Molecules for Sustainable Technologies
January 31, 2013 — Scientists in the joint research project "FUNgraphen" are pinning their hopes for new technologies on a particular form of carbon: They have developed new carbon macromolecules and molecular carbon ... > full story -
New Options for Transparent Contact Electrodes
January 29, 2013 — Found in flat screens, solar modules, or in new organic light-emitting diode (LED) displays, transparent electrodes have become ubiquitous. Typically, they consist of metal oxides like In2O3, SnO2, ... > full story -
Toward 2-D Devices: Single-Atom-Thick Patterns Combine Conductor and Insulator
January 27, 2013 — Scientists have created a process to make patterns in atom-thick layers that combine a conductor -- graphene -- and an insulator -- hexagonal boron nitride. The process may lead to new possibilities ... > full story -
Evolution Inspires More Efficient Solar Cell Design: Geometric Pattern Maximizes Time Light Is Trapped
January 25, 2013 — Using a mathematical model based on natural evolution, researchers have developed an organic solar cell design that could pave the way for more efficient, less expensive solar ... > full story -
Controlled Crumpling of Graphene Forms Artificial Muscle
January 23, 2013 — Engineers are layering atom-thick lattices of carbon with polymers to create unique materials with a broad range of applications, including artificial ... > full story -
Nanoparticles Digging the World's Smallest Tunnels
January 23, 2013 — The world’s smallest tunnels have a width of a few nanometers only. Researchers have dug such tunnels into graphite samples. This will allow structuring of the interior of materials through ... > full story
