Novel double slot structure gives rise to the enhanced performance of graphene/silicon hybrid photodetector

Aug 10, 2022 (Nanowerk News) The ongoing fourth industrial revolution is data-driven and the optical interconnects are expected to feature higher bandwidth, smaller footprint, and lower power consumption to meet the dramatically growing demand for stronger data processing ability. As a key element of the optical communication systems, a photodetector...

First-ever detection of gas in a circumplanetary disk

Aug 09, 2022 (Nanowerk News) Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA)— in which the National Radio Astronomy Observatory (NRAO) is a partner— to study planet formation have made the first-ever detection of gas in a circumplanetary disk. What’s more, the detection also suggests the presence of a very...

Chemists achieve ‘molecular editing’ feat

Aug 09, 2022 (Nanowerk News) Chemists from Scripps Research and the University of California, Los Angeles, have developed methods for the precise, flexible modification of a broad class of chemical compounds called bicyclic aza-arenes, which are commonly used to build drug molecules. The landmark achievement, reported in Nature ("Molecular editing...

Physicists switch magnetic state using spin current

Aug 09, 2022 (Nanowerk News) When Carnegie Mellon University doctoral candidates I-Hsuan Kao and Ryan Muzzio started working together a switch flicked on. Then off. Working in the Department of Physics' Lab for Investigating Quantum Materials, Interfaces and Devices (LIQUID) Group, Kao, Muzzio and other research partners were able to...

Do ‘bouncing universes’ have a beginning?

Aug 09, 2022 (Nanowerk News) In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles. Because this behavior is hypothesized to be perpetual, the universe should have no beginning and no end — only eternal cycles of growing and...
