Electron beams are often treated as a problem in molecular electron microscopy: powerful enough to reveal structure, but also capable of damaging the very samples under study. A recent paper published in Angewandte Chemie International Edition suggests a different possibility: what if beam damage could be harnessed as beam-enabled chemistry?

Researchers from UC Santa Barbara’s BioPACIFIC MIP have reported a new route to making commodity plastics more sustainable without requiring major changes to existing manufacturing methods.

Large single crystals with precise stoichiometry control are the cornerstones of modern-day microelectronics, global positioning systems, optical communications, energy harvesting, etc. In addition, fundamental research also relies heavily on ideal single crystals to access intrinsic properties. One central challenge in crystal growth by conventional techniques such as Czochralski and Bridgman is that large, high-quality crystals can be grown only for congruent melting compositions where the solid and liquid compositions are the same.
