Real-time Visualization of Nanoparticles Self-Assembling into Crystals.

Researchers from Northwestern University and the University of Illinois have observed nanoparticles self-assembling into solid materials for the first time, offering valuable insights for the design of new materials, such as thin films for electronics. The study used a newly optimized form of liquid-phase transmission electron microscopy (TEM) to gain unprecedented insights into the self-assembly process. The researchers say this information will help engineers design new materials, specifically thin-film materials, which are often used to build flexible electronics, light-emitting diodes, transistors, and solar cells.
