Spintronics: Faster data processing through ultrashort electric pulses

2 июля, 2020 - 17:05
Physicists have developed a simple concept that could improve significantly magnetic-based data processing. Using ultrashort electric pulses in the terahertz range, data can be written, read and erased very quickly. This would make data processing faster, more compact and energy efficient. The researchers confirmed their theory by running complex simulations.

Materials scientists drill down to vulnerabilities involved in human tooth decay

1 июля, 2020 - 19:54
Researchers have cracked one of the secrets of tooth decay. The materials scientists are the first to identify a small number of impurity atoms in human enamel that may contribute to the material's strength but also make it more soluble. They also are the first to determine the spatial distribution of the impurities with atomic-scale resolution. The discovery could lead to a better understanding of human tooth decay as well as genetic conditions that affect enamel formation.

Buzzing to rebuild broken bone

30 июня, 2020 - 18:15
Healing broken bones could get easier with a device that provides both a scaffold for the bone to grow on and electrical stimulation to urge it forward, engineers report. Although minor bone breaks usually heal on their own, large fractures with shattered or missing chunks of bone are more difficult to repair. A biocompatible, dissolving polymer device can mimic the body's natural electrical field and help the cells regenerate.
