Mon. 12 Mar 2018. A milestone in petahertz electronics. In a semiconductor, electrons can be excited by absorbing laser light. Advances during the past decade enabled measuring this fundamental physical mechanism on timescales below a femtosecond (10^-15 s). Physicists now for the first time resolved the response of electrons in gallium arsenide at the attosecond (10^-18 s) timescale, and gained unexpected insights for future ultrafast opto-electronic devices with operation frequencies in the petahertz regime.

Tue. 20 Feb 2018. New Approach Can Help Authorities Respond More Quickly to Airborne Radiological Threats. At present, emergency responders who are characterizing potential radiological risk need to take an air sample and ship it to a radiochemistry lab after preliminary screening analysis. The process means it can take days or weeks to get quality results that authorities can use to make informed decisions. The new approach uses existing technologies to detect potential airborne radiological materials in hours instead of days. It involves using a radiation detector to take multiple periodic measurements of an air sample for at least two hours. The measurements are then run through a computer model that uses the data to estimate the potential worst case scenario regarding “transuranic” activity in the area. More




Thu. 18 Jan 2018. Ultra-Thin Memory Storage Device Paves Way for More Powerful Computing. A team of electrical engineers has developed the thinnest memory storage device with dense memory capacity, paving the way for faster, smaller and smarter computer chips for everything from consumer electronics to big data to brain-inspired computing.

Mon. 15 Jan 2018. The atomic dynamics of rare everlasting electric fields. By ricocheting neutrons off the atoms of yttrium manganite (YMnO3) heated to 3,000 degrees Fahrenheit, researchers have discovered the atomic mechanisms that give the unusual material its rare electromagnetic properties. The discovery could help scientists develop new materials with similar properties for novel computing devices and micro-actuators. More
