Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have developed an optical switch that routes light from one
Imagine a single particle, only one-tenth the diameter of a bacterium, whose miniscule jiggles induce sustained vibrations in an entire mechanical device some
Scientists at the National Institute of Standards and Technology (NIST) have developed a new device that measures the motion of super-tiny particles traversing
Conventional techniques for analyzing chemical composition, such as infrared (IR) microscopy often miss critically important nanoscale details. To overcome this
Nano and atomic scale theory of the electronic, optical and mechanical properties of ultrasmall structures, such as semiconductor quantum dots and dopants in Si
Metamaterials are tailor-made photonic composites--combinations of materials designed to achieve optical properties not seen in nature. The properties stem from
Electrochemical systems containing nanostructured materials are increasingly being incorporated into devices for efficiently harvesting, storing, and converting
