Shining light on a growing semiconductor modifies its interface with the surface and could improve the optical properties of each.
Vector polarizers are a light filtering technology hidden behind the operation of many optical systems. They can be found, for instance, in sunglasses, LCD screens, microscopes, microprocessors, laser machining and more. Optical physicists published details of their new vector polarizer design this week in APL Photonics. The newly proposed design is a major advance in polarization technology because it enables flexible filtering of a wide range of light sources and generation of new light states.
Scientists at Johns Hopkins have used supercomputers to create an atomic scale map that tracks how the signaling chemical glutamate binds to a neuron in the brain. The findings, say the scientists, shed light on the dynamic physics of the chemical's pathway, as well as the speed of nerve cell communications.
Scientists have come up with a way to massively speed up the ordering process for self-assembling materials. The resulting ultra-small, well-ordered patterns could be used in the fabrication of microelectronics, antireflective surfaces, magnetic data storage systems, and fluid-flow devices.
Neuroscientists can now explore a beta version of the new Neurodata Without Borders: Neurophysiology (NWB:N 2.0) software and offer input to developers before it is fully released next year.

For decades, scientists have been trying to make a true molecular chain: a repeated set of tiny rings interlocked together. In a study in Science published online Nov. 30, University of Chicago researchers announced the first confirmed method to craft such a molecular chain.
An international team of researchers ran multi-scale, multi-physics 2D and 3D simulations at NERSC to illustrate how heavy metals expelled from exploding supernovae held the first stars in the universe regulate subsequent star formation and influence the appearance of galaxies in the process.
Supercapacitors can store more energy than and are preferable to batteries because they are able to charge faster, mainly due to the vertical graphene nanosheets that are larger and positioned closer together. Using VGNs as the material for supercapacitor electrodes offers advantages due to their intriguing properties, and those advantages can be enhanced depending on how the material is grown, treated and prepared to work with electrolytes. In this week's Journal of Applied Physics, researchers discuss their work to improve the material's supercapacitance properties.
