Guided self-assembly of gold thin films

Berkeley Lab and UC Berkeley scientists have successfully directed the self­-assembly of nanoparticles into device-ready thin films, which have potential applications in fields ranging from computer memory storage to energy harvesting and storage, from catalysis to light management, and into the emerging new field of plasmonics.

Scientists image the molecular structure of polymer blends

Using an enhanced form of 'chemical microscopy' developed at the National Institute of Standards and Technology (NIST), researchers there have shown that they can peer into the structure of blended polymers, resolving details of the molecular arrangement at sub-micrometer levels.

The first controllable atom SQUID

Scientists have created the first controllable atomic circuit that functions analogously to a superconducting quantum interference device (SQUID) and allows operators to select a particular quantum state of the system at will.

Experiments challenge fundamental understanding of electromagnetism

A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest that the most rigorous predictions based on the fundamental theory of electromagnetism - one of the four fundamental forces in the universe, and harnessed in all electronic devices - may not accurately account for the behavior of atoms in exotic, highly charged states.

Nanotechnology: smiles all round

A smile can say more than a thousand words, the saying goes. Orthodontics can help improve the appearance and position of people's teeth and jawbones, for better functioning teeth and more attractive smiles. In recent years, dental correction orthodontics have used braces made from clear plastic polymer to good effect, but now they are hoping to improve on this with help from nanotechnology.

Graphene switches: Research group makes it to first base

Researchers have taken the first step towards building graphene-based components. They successfully managed to increase the graphene conduction electrons' spin-orbit coupling by a factor of 10,000 - enough to allow them to construct a switch that can be controlled via small electric fields.
