Reusable Breakaway Mounting Device

Breakaway devices are used to mount objects to systems or structures (for example, cars, drones, helmets, buildings) and prevent damage when the objects fall away from the system. Unfortunately, even in ideal scenarios, many of these devices have limitations. Breakaway bolts and shear pins have the complication...

Conventional lithium-ion batteries cannot be rapidly charged at temperatures below 50 °F. Electric vehicles are popular on the West Coast because the weather is...

Relying on advanced materials such as perovskites and single-walled carbon nano-tubes, a window technology was developed that responds to heat by transforming from transparent to...
