Demonstrating a strategy that could form the basis for a new class of electronic devices with uniquely tunable properties, researchers were able to widely vary the emission color and efficiency of organic light-emitting diodes based on exciplexes simply by changing the distance between key molecules in the devices by a few nanometers.
Imagine solar cells so thin, flexible, and lightweight that they could be placed on almost any material or surface, including your hat, shirt, or smartphone, or even on a sheet of paper or a helium balloon.
Scientists have developed a method of producing hydrogen peroxide on demand through a simple, one-step process. The method enables dilute H2O2 to be made directly from hydrogen and oxygen in small quantities on-site.
Researchers have been studying the lubricity of graphene on the nanometer scale. Since it produces almost no friction at all, it could drastically reduce energy loss in machines when used as a coating.
Just as the single-crystal silicon wafer forever changed the nature of electronics 60 years ago, a group of researchers is hoping its work with quantum dot solids - crystals made out of crystals - can help usher in a new era in electronics.
Scientists have found evidence that some carbon nanomaterials can enter into immune cell membranes, seemingly going undetected by the cell's built-in mechanisms for engulfing and disposing of foreign material, and then escape through some unidentified pathway.
Researchers have proved that copper nanophotonic components can operate successfully in photonic devices - it was previously believed that only gold and silver components have the required properties for this. It means that light-based computers are closer to reality than ever before - copper is cheaper than gold or silver.
