Spinning CDs to clean sewage water

Audio CDs, all the rage in the '90s, seem increasingly obsolete in a world of MP3 files and iPods, leaving many music lovers with the question of what to do with their extensive compact disk collections. While you could turn ...

Glass has potential to be stronger, researchers say

(Phys.org)—Glass is strong enough for so much: windshields, buildings and many other things that need to handle high stress without breaking. But scientists who look at the structure of glass strictly by the numbers believe ...

Using rust and water to store solar energy as hydrogen

How can solar energy be stored so that it can be available any time, day or night, when the sun shining or not? EPFL scientists are developing a technology that can transform light energy into a clean fuel that has a neutral ...

Water Motions Revealed (w/ Video)

(PhysOrg.com) -- Gaze into a glass of water, and you're unlikely to see much more than your own reflection. But gaze a little deeper using a microscope -- or, better yet, a series of laser pulses and detectors -- and you'll ...

Highly efficient oxygen catalyst found

A team of researchers at MIT has found one of the most effective catalysts ever discovered for splitting oxygen atoms from water molecules — a key reaction for advanced energy-storage systems, including electrolyzers, ...

Physicists make crystal/liquid interface visible for first time

"Imagine you're a water molecule in a glass of ice water, and you're floating right on the boundary of the ice and the water," proposes Emory University physicist Eric Weeks. "So how do you know if you're a solid or a liquid?"

The world's cleanest water droplet

In nature, there is no such thing as a truly clean surface. Contact with normal air is sufficient to coat any material with a thin layer of molecules. This "molecular dirt" can change the properties of the material considerably, ...

Little ANTs: Researchers build the world's tiniest engine

Researchers have developed the world's tiniest engine - just a few billionths of a metre in size - which uses light to power itself. The nanoscale engine, developed by researchers at the University of Cambridge, could form ...
