GEARS ABRADE, pistons crack, pumps clog. If engineers had their way, machines would have no moving parts at all. Alas, a sedentary lump of metal would be a paperweight, rather than a useful machine.

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, ...

Scientists have developed a tailored ionic liquid that stabilises perovskite solar cells, allowing them to retain about 90% ...

Driving systems out of equilibrium with electric fields proves useful for creating liquid shapes that are nearly impossible to find in nature. When two substances are brought together, they will ...

Going bottom-up is no problem for a boat on the underside of a levitated liquid. In a container, liquid can be levitated over a layer of gas by shaking the container up and down because the repeated, ...

An elusive form of matter called a quantum spin liquid isn’t a liquid, and it doesn’t spin — but it sure is quantum. Predicted nearly 50 years ago, quantum spin liquids have long evaded definitive ...

Although optical fibers are highly effective at data transmission, they're also relatively brittle. An experimental new type of optical fiber addresses that limitation, by incorporating a core made of ...

People who investigate scientific topics either love or hate glass, which is a confusing none-of-the-above unicorn: neither fully liquid nor fully solid, exhibiting some properties of each, but ...
