Key To Resilient Energy-Efficient AI/Machine Learning May Reside In Human Brain

A clearer understanding of how a type of brain cell known as astrocytes function and can be emulated in the physics of hardware devices may result in artificial intelligence (AI) and machine learning that autonomously self-repairs and consumes much less energy than the technologies currently do.

Study Challenges Standard Ideas About Piezoelectricity In Ferroelectric Crystals

For years, researchers believed that the smaller the domain size in a ferroelectric crystal, the greater the piezoelectric properties of the material. However, recent findings by Penn State researchers have raised questions about this standard rule.

When A Defect Is A Good Thing

Defects in the lattice structure of hexagonal boron nitride can be detected with photoluminescence. Researchers shine a light with a color or energy on the material and get a different color from the defect. In addition, the figure shows hydrogen bubbles being generated from these defects that contain catalyst atoms (gray and dark spheres attached to the vacancies).

Tiny defects hold key to turning inert materials into more useful chemically active ones
