Motor proteins generate the forces for essential mechanical processes in our body. On a scale of nanometers—a millionth of a millimeter—motor proteins, for example, power our muscles or transport material...

Artistic rendering of fast ion permeation inside single-walled carbon nanotubes. Small ions such as potassium, chloride, and sodium permeate through the inner volume of nanometer-wide carbon nanotubes at rates that...

Brookhaven chemists Enyuan Hu (left, lead author) and Zulipiya Shadike (right, first author) are shown holding a model of 1,2-dimethoxyethane, a solvent for lithium metal battery electrolytes. Credit: Brookhaven National...

The new single-photon source is based on excitation of a quantum dot (shown as a bulge on the bottom left), which then emits photons. A micro-cavity ensures that the photons...

Researchers have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behavior, making it possible to detect a...

An optically excited gas of electronic carriers confined to the planes of the layered van-der Waals semiconductor tungsten diselenide is shown. The consequent hyperbolic response permits passage of nanolight. Credit:...

Engineers have developed a technique that allows them to precisely place microscopic devices formed from folded DNA molecules in not only a specific location but also in a specific orientation....

MIT researchers are developing a superconducting nanowire, which could enable more efficient superconducting electronics. Credit: Christine Daniloff, MIT. Superconductors—materials that conduct electricity without resistance—are remarkable. They provide a macroscopic glimpse...
