Chemists find key to manufacturing more efficient solar cells

In a discovery that could have profound implications for future energy policy, Columbia scientists have demonstrated it is possible to manufacture solar cells that are far more efficient than existing silicon energy cells ...

Move over, silicon switches: There's a new way to compute

Logic and memory devices, such as the hard drives in computers, now use nanomagnetic mechanisms to store and manipulate information. Unlike silicon transistors, which have fundamental efficiency limitations, they require ...

Researchers harness mysterious Casimir force for tiny devices

Getting something from nothing sounds like a good deal, so for years scientists have been trying to exploit the tiny amount of energy that arises when objects are brought very close together. It's a source of energy so obscure ...

Mysteries behind interstellar buckyballs finally answered

Scientists have long been puzzled by the existence of so-called "buckyballs"—complex carbon molecules with a soccer-ball-like structure—throughout interstellar space. Now, a team of researchers from the University of ...
