Century-old electrochemistry law gets update

The Gouy-Chapman theory describes what happens near an electrode when it is in contact with a salt solution, but this description does not match reality. Researcher Kasinath Ojha, assistant professor Katharina Doblhoff-Dier ...

Stockholm techies use water to charge mobile phones

(PhysOrg.com) -- A Swedish company headquartered in Stockholm has figured out how to power smartphones using a system that includes some water, a tray, a little round container, and an eyeglass case styled cover. The company, ...

New fuel cell design powered by graphene-wrapped nanocrystals

Hydrogen is the lightest and most plentiful element on Earth and in our universe. So it shouldn't be a big surprise that scientists are pursuing hydrogen as a clean, carbon-free, virtually limitless energy source for cars ...

Materials that shrink when heated

One common reason that people with fillings experience toothache is that their fillings expand at a different rate to the original tooth when, for example, drinking a hot drink. Contrary to intuition, however, not all materials ...

New water-splitting catalyst found

(PhysOrg.com) -- Expanding on work published two years ago, MIT's Daniel Nocera and his associates have found yet another formulation, based on inexpensive and widely available materials, that can efficiently catalyze the ...

New material could advance superconductivity

Scientists have looked for different ways to force hydrogen into a metallic state for decades. A metallic state of hydrogen is a holy grail for materials science because it could be used for superconductors, materials that ...
