Birthing a new breed of materials

Where two different materials meet on the atomic level, a new material can be born that is neither one nor the other. The two parent materials do not mix – they remain distinct from one another – but their marriage begets ...

Low-priced plastic photovoltaics

Photovoltaic devices, which tap the power of the sun and convert it to electricity, offer a green—and potentially unlimited—alternative to fossil fuel use. So why haven't solar technologies been more ...

Wrangling flow to quiet cars and aircraft

Plasmas are a soup of charged particles in an electric field, and are normally found in stars and lightning bolts. With the use of high voltage equipment, very small plasmas can be used to manipulate fluid ...

How Earth's rotation affects vortices in nature

What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an imaginary straight or curved ...
