Galinstan

Thanks to a mechanochemically engineered combination of the liquid metal alloy Galinstan and ceramic aluminum nitride, this thermal interface material, or TIM, outperformed the best commercial liquid...

In a new study, researchers show off a tiny lego-like robot that can switch between matter states using the power of magnets.

Magnetoactive phase transitional matter that is composed of NdFeB microparticles embedded in liquid metal can achieve high mechanical strength (stiffness, 1.98 GPa), high load capacity, fast and multimodal locomotion (jumping up to 20× body length, moving up to 1.5 m/s) in its solid state, and excellent morphological adaptability (elongation, splitting, and merging) in its liquid state. This stimuli-responsive…

At the center of Earth is a vast ball of metal, the planet's core. While unreachable without the help of Jules Verne, it can be studied and plays a vital role for the world.

Having Covid is a good excuse to bitch about...whatever. I chose digital thermometers. Hateful monstrosities.

Most soft robots are slow, but these feel the need for speed.
