Liquid metals come to the rescue of semiconductors

Moore's law is an empirical suggestion stating that the number of transistors doubles every few years in integrated circuits (ICs). However, Moore's law has started to fail as transistors are now so small that current silicon-based ...

Discovery of disordered nanolayers in intermetallic alloys

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 ...

Researchers develop computational model to build better capacitors

Researchers at North Carolina State University have developed a computational model that helps users understand how changes in the nanostructure of materials affect their conductivity—with the goal of informing the development ...

Understanding the 'fundamental nature' of atomic-scale defects

Materials scientists study metals, polymers, and other substances at the atomic level in order to find new ways to control a material's physical properties, such as how strong or how malleable it is. One key aspect of this ...

Single atom layer trap for lithium-ion migration

On April 14th, Prof. Ma Cheng from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) and his colleagues reported an important discovery regarding the mechanism of Li-ion migration ...

A new strategy to create 2-D magnetic order

Grain boundaries, which consist of periodic arrangement of structural units and are generally recognized as a two-dimensional "phase," can exhibit novel properties that do not exist in the intrinsic bulk crystal. The altered ...

Seeing how grain boundaries transform in a metal

Grain boundaries are one of the most prominent defects in engineering materials separating different crystallites, which determine their strength, corrosion resistance and failure. Typically, these interfaces are regarded ...
