A molecular electronic switch is a junction created from individual molecules that can alternate between two or more stable states, making the switch act as a conductor or an insulator. These switches ...

Researchers are learning to flip light on and off one particle at a time, turning single photons into a controllable resource instead of a random byproduct of exotic materials. By engineering ...

ORNL researchers performing basic research have discovered a carbon nanotube-based system that functions like an atom-scale switch. Their approach is to perform first-principles calculations on ...

Stuttgart-based physicists observe the critical Casimir force and use it to cancel out an effect that brings nanomachines to a standstill. When a machine jams, it's the fault of the engineer - or of ...
