Researchers use sound to slow down, speed up, and block light

Researchers have experimentally demonstrated, for the first time, the phenomenon of Brillouin Scattering Induced Transparency (BSIT), which can be used to slow down, speed up, and block light in an optical waveguide. The BSIT phenomenon permits light to travel in the forward direction while light traveling in the backward direction is strongly absorbed.

Nanoscale lubrication of ionic surfaces

Friction impacts motion, hence the need to control friction forces. Currently, this is accomplished by mechanistic means or lubrication, but experiments conducted by researchers at Oak Ridge National Laboratory have uncovered a way of controlling friction on ionic surfaces at the nanoscale using electrical stimulation and ambient water vapor.

'Rapid response to Ebola' grant

Health care workers must diagnose and isolate Ebola victims at an early stage to have a chance to save them and prevent the virus from spreading. But the most sensitive and quickest diagnostic test produces a small percentage of false negative results that undermine efforts to control the deadly agent. A $100,000 National Science Foundation (NSF) grant has been awarded to develop a method to reduce the risk of the virus going undetected.

New pathway to valleytronics

A potential avenue to quantum computing currently generating quite the buzz in the high-tech industry is 'valleytronics', in which information is coded based on the wavelike motion of electrons moving through certain two-dimensional (2D) semiconductors. Now, a promising new pathway to valleytronic technology has been uncovered.

Carbon nanoballs can greatly contribute to sustainable energy supply

Researchers have discovered that the insulation plastic used in high-voltage cables can withstand a 26 per cent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system.

Peptide nanoparticle delivery of oligonucleotide drugs into cells

Therapeutic oligonucleotide analogs represent a new and promising family of drugs that act on nucleic acid targets such as RNA or DNA; however, their effectiveness has been limited due to difficulty crossing the cell membrane. A new delivery approach based on cell-penetrating peptide nanoparticles can efficiently transport charge-neutral oligonucleotide analogs into cells.
