Under extreme impacts, metals get stronger when heated, study finds      (via sciencedaily.com)     Original source 

Scientists have discovered that when metal is struck by an object moving at a super high velocity, the heat makes the metal stronger. The finding could lead to new approaches to designing materials for extreme environments, such as shields that protect spacecraft or equipment for high-speed manufacturing.

Powering wearable devices with high-performing carbon nanotube yarns      (via sciencedaily.com)     Original source 

Carbon nanotube (CNT) yarns are promising for flexible and fabric-type wearable materials that can convert waste heat into thermoelectricity. To improve the thermoelectric properties of CNT yarns, researchers dispersed CNT filaments in a highly viscous glycerol, enabling the production of CNT yarn with highly aligned bundles together with surfactants that prevent increased thermal conductivity. This innovative approach can significantly improve carbon nanotube-based thermoelectric materials, making it possible to power wearable devices using just body heat.

Blueprints of self-assembly      (via sciencedaily.com)     Original source 

Scientists have taken a step closer to replicating nature's processes of self-assembly. The study describes the synthetic construction of a tiny, self-assembled crystal known as a 'pyrochlore,' which bears unique optical properties. The advance provides a steppingstone to the eventual construction of sophisticated, self-assembling devices at the nanoscale -- roughly the size of a single virus.

Expanding on the fundamental principles of liquid movement      (via sciencedaily.com)     Original source 

We are living in a world surrounded by liquid and flow, and understanding the principles that govern its movement is vital in our high-tech world. Through mathematical modeling and experimentation, researchers have expanded on Tanner's Law -- a law in fluid dynamics that describes how non-volatile liquids move across surfaces -- to cover a wider range of volatile liquids. These findings have the potential to play a role in various liquid-based industries such as electronics cooling.
