Researchers discovered that the self-powered liquid metal motors in millimeter scale demonstrated similar Brownian like motion behaviors in alkaline solution. And the force comes from the hydrogen gas stream generated at the interface between liquid metal motor and its contacting substrate bottom.

Researchers have found that irradiation of the material creates nanometer-sized defects that trap swirling eddies in the flow of electrons, keeping them out of the way so more current can flow.

Chemists truly went back to the drawing board to develop new X-shaped organic building blocks that can be linked together by metal ions to form an Archimedean cuboctahedron. They report that by changing the concentration or using different counterions, the cuboctahedron can be reversibly split into two octahedra - an interesting new type of fusion-fission switching process.

Elevated or diminished eye pressure impairs our ability to see, and in the worst cases, can even lead to blindness. Until now, there has been no effective long-term treatment. In response, researchers are developing an implantable microfluid system that can efficiently and durably stabilize intraocular pressure.
