Posted: 08 Oct 2021 01:05 PM PDT New research has uncovered a novel way to combine two different states of matter. For one of the first times, topological photons -- light -- has been combined with lattice vibrations, also known as phonons, to manipulate their propagation in a robust and controllable way. |
Sensitive new way of detecting transistor defects Posted: 08 Oct 2021 01:05 PM PDT Researchers have devised and tested a new, highly sensitive method of detecting and counting defects in transistors -- a matter of urgent concern to the semiconductor industry as it develops new materials for next-generation devices. |
Taking steps toward more effective fitness trackers, more physical activity Posted: 08 Oct 2021 01:04 PM PDT As the popularity of fitness trackers has increased, so have the opportunities to use such devices to not only track fitness goals but also increase the motivation to meet those goals. Researchers are using control systems engineering tools to tailor motivational messages sent to individual device users. |
Refuting a 70-year approach to predicting material microstructure Posted: 07 Oct 2021 11:59 AM PDT Researchers have developed a new microscopy technique that maps material microstructure in three dimensions; results demonstrate that the conventional method for predicting materials' properties under high temperature is ineffective. |
