Researchers have developed a simple way to align molecules in one direction on a flat graphene surface. Efficiently controlling molecular alignment is expected to lead to significant progress in surface chemistry and molecular engineering, as well as materials science.
A team of researchers compared the susceptibility of different triangle silver nanoprisms (TSNPRs) towards H2O2 and elucidated the influence of capping agents and structural size on the etching process, with the aim of optimizing TSNPRs for H2O2 etching-based biosensors, such as glucose and glucose oxidase.
Researchers have demonstrated reliable operation of microelectromechanical relays by coating the contacts with nanocrystalline layers of graphite, to enable ultra-low-power electronics for harsh environments.
It's likely not the first thing you think of when you see elephant dung, but this material turns out to be an excellent source of cellulose for paper manufacturing in countries where trees are scarce, scientists report.
Tiny floating robots could be useful in all kinds of ways, for example, to probe the human gut for disease or to search the environment for pollutants. In a step toward such devices, researchers describe a new marriage of materials, combining ultrathin 2-D electronics with miniature particles to create microscopic machines.
