Scientists from the US Army Research Laboratory and the Lawrence Livermore National Laboratory found a solution to a significant challenge in making high-energy explosives.
Atomic-resolution transmission electron microscopy of electron beam-sensitive crystalline materials.
When German researchers zoomed in to the nanometer scale on time-lapse images of dissolving crystals, they found a surprise: Dissolution happened in pulses, marked by waves that spread just like ripples on a pond.
Data travels through thousands of miles of fiber optic cables underneath the world's oceans--via pulses of light. And according to experts, the data in these cables is at great risk of being intercepted. However, a newly designed frequency comb--recently developed by researchers at the USC Viterbi School of Engineering might be an effective tool for data encryption.
At a special session held during the American Astronomical Society meeting in Washington, D.C., scientists on the Dark Energy Survey (DES) announced today the public release of their first three years of data. This first major release of data from the Survey includes information on about 400 million astronomical objects, including distant galaxies billions of light-years away as well as stars in our own galaxy.
Photonic crystals are perfect materials for controlling light beams. The crystals almost managed to become the basis for the production of optical processors several years ago, if not for one highly ranked official saying 'no.' Similar to many other materials whose properties strongly depend on their structure, photonic crystals have an issue of reproducibility. To put it more exactly, no one has yet managed to create two large and completely similar photonic crystals.
Scientists analyzing results of spinning protons striking different sized atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) found an odd directional preference in the production of neutrons that switches sides as the size of the nuclei increases. The results offer new insight into the mechanisms affecting particle production in these collisions.
Scientists from Griffith University have overcome a major challenge in applying a strange quantum effect to real applications.
Researchers at the US Army Research Laboratory and the Ludwig Maximilian University in Munich, Germany, have developed an environmentally friendly red light flare popular in fireworks displays and among Soldiers who use them in training and battlefield operations as signaling devices.
For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials theorized to exist only in four-dimensional space. An international team of researchers demonstrated that the behavior of particles of light can be made to match predictions about the four-dimensional version of the 'quantum Hall effect' -- a phenomenon at the root of three Nobel Prizes in physics -- in a two-dimensional array of 'waveguides.'
