The electron is an elementary particle, a building block on which other systems evolve. With specific properties such as spin, or angular momentum, that can be manipulated to carry information, electrons are primed to advance modern information technology. An international collaboration of researchers has now developed a way to extend and stabilize the lifetime of the electron's spin to more effectively carry information.

Intermetallic alloys potentially have high strength in a high-temperature environment. But they generally suffer poor ductility at ambient and low temperatures, hence limiting their applications in aerospace and other engineering fields. Yet, a research team led by scientists of City University of Hong Kong (CityU) has recently discovered the disordered nanoscale layers at grain boundaries in the ordered intermetallic alloys. The nanolayers can not only resolve the irreconcilable conflict between strength and ductility effectively, but also maintain the alloy’s strength with excellent thermal stability at high temperatures. Designing similar nanolayers may open a pathway for the design of new structural materials with optimal alloy properties.
