When cancer spreads from one part of the body to another, it becomes even more deadly. It moves with stealth and can go undetected for months or years. But a new technology that uses 'nano-flares' has the potential to catch these lurking, mobilized tumor cells early on.
Researchers have developed a new processing technique that makes light emitting diodes (LEDs) brighter and more resilient by coating the semiconductor material gallium nitride (GaN) with a layer of phosphorus-derived acid.
To unlock the vast potential of metal oxide interfaces, especially those buried in subsurface layers, scientists need even more detailed knowledge of their electronic structure. And a new technique - called SWARPES, for Standing Wave Angle-Resolved Photoemission Spectroscopy - promises to deliver the goods.
Even the best Li-ion batteries degrade with time. A reason for this was now identified by researcher. They could directly observe atomic rearrangements occurring in the cathode material of Li-ion batteries during charge and discharge processes.
The research focuses on using insulated nanocomposite magnetic materials as the filling material to shrink the size and improve the performance of high frequency on-chip inductors, thereby enabling a new wave of miniaturized electronics and wireless communications devices.
Researchers have found a way to reduce the coercivity of nickel ferrite thin films by as much as 80 percent by patterning the surface of the material, opening the door to more energy efficient high-frequency electronics, such as sensors, microwave devices and antennas.
Carbon nanotubes are becoming increasingly attractive for photovoltaic solar cells as a replacement to silicon. Researchers have discovered that controlled placement of the carbon nanotubes into nano-structures produces a huge boost in electronic performance.
Rersearchers have succeeded for the first time to produce uniform antimony nanocrystals. Tested as components of laboratory batteries, these are able to store a large number of both lithium and sodium ions.
