Researchers at the Department of Energy’s Oak Ridge National Laboratory have created a new detection system that allows home energy auditors to see air leaking from a building in real time with the help of a camera. It’s an advancement that could provide more accurate readings far more quickly than current diagnostic tools allow.

For months, U.S. officials have been sniffing out malicious computer code that they suspect to be planted inside the power grid and communication control systems on U.S. military bases. Virginia Tech researchers already are working on a plan to secure future military base power grid operations and their critical missions from such threats.

As the number of elements on phased array antennas continues to grow, so does the volume of data that must be processed. To address this, researchers have developed a new approach to process that data closer to where it is generated - on the antenna subarrays themselves.

Comparing experimental results and theoretical calculations can be difficult for quantum materials. One solution is to use sample materials that isolate and emphasize an atomic line with one dimensional properties. In this study, scientists grew thin films of layered copper-oxygen materials to experimentally test theories of electron interaction in quantum materials. The study indicates that standard theory is not sufficient and requires a new term to fit the experimental data.

A Fabry-Perot (F-P) based phase demodulation of heterodyne light-induced thermoelastic spectroscopy (H-LITES) is demonstrated. The vibration of quartz tuning fork (QTF) was detected by using F-P interferometer (FPI) to avoid the thermal noise. Given that FPI is vulnerable to disturbance, a phase demodulation method is employed in H-LITES. This new method of phase demodulation is structurally simple and was found to be resistant to interference from light sources and the surroundings using the LITES technique.
