Researchers solve 100-year-old metallurgy puzzle

To solve a 100-year puzzle in metallurgy about why single crystals show staged hardening while others don't, Lawrence Livermore National Laboratory (LLNL) scientists took it down to the atomistic level.

Having a ball: Crystallization in a sphere

Crystallization is the assembly of atoms or molecules into highly ordered solid crystals, which occurs in natural, biological, and artificial systems. However, crystallization in confined spaces, such as the formation of ...

Researchers fabricate high-quality transparent ceramic

Mid-infrared lasers have been widely used in imaging, detection, diagnostics, environmental monitoring, medicine, industry, defense and others. For mid-infrared laser systems, low phonon energy gain materials are key factors.

Tuning the surface gives variations to metal foils

Just as cloning in biology allows for the creation of one or more replicas of the exact same genes, seeded growth in chemistry can produce a very large metal foil with the exact same surface texture as that of a seeded one. ...

Isolating an elusive phosphatetrahedrane

A research team in the Department of Chemistry at the Massachusetts Institute of Technology (MIT), Cambridge U.S., explored a synthetic pathway to generate a phosphatetrahedrane framework. During the synthetic route, the ...

Technique reveals how crystals form on surfaces

The process of crystallization, in which atoms or molecules line up in orderly arrays like soldiers in formation, is the basis for many of the materials that define modern life, including the silicon in microchips and solar ...
