Thin explosive films provide snapshot of how detonations start

March 4, 2021 sarah Jonas Computational Modeling, detonation, Explosives, Materials Science

Using thin films — no more than a few pieces of notebook paper thick — of a common explosive chemical, researchers from Sandia National Laboratories studied how small-scale explosions start and grow. These experiments advanced fundamental knowledge of detonations.

Fluorescent Metal Organic Frameworks Go Dark to Detect Explosives

February 4, 2021 sarah Jonas Materials Science, Metal Organic Frameworks, metal-organic framework

Scientists recently investigated the factors that control fluorescent light signals from metal organic frameworks (MOFs). The light may turn on due to structural changes in the MOF and turn off due to reorganization of the electrons in the MOF. Understanding these factors advances researchers’ ability to design and use MOFs as chemical sensors.
