Trapped in a microscopic cage made of strands of DNA, molecules of a life-saving drug course through the bloodstream of a cancer patient. Only when receptors on
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
The aim of this project is twofold: 1) improve the PTIR measurement (spectral range, signal to noise ratio, throughput, time resolution, information content, range of environmental conditions) and 2) apply PTIR to characterize nanomaterials in important applications. Examples or recent PTIR
Plasmonic materials are composed of metals and insulators that are ordered in geometric arrangements with dimensions that are fractions of the wavelength of light. Research groups are experimenting with a variety of geometric approaches, but all aim
to exploit surface plasmons, which are light
Transportation is the single largest contributor to U.S. carbon dioxide emissions. Moving to an electrically powered transportation system that draws on sustainable energy supplies has the potential to lower transportation costs, reduce greenhouse gas emissions, and help further reduce the nation's
Developing and exploiting nanodevices for quantum and nanotechnologies requires nanoscale and atomic scale modeling of ultrasmall structures, devices, their operation, and their response to probes. Key challenges of understanding physics at the quantum/classical interface and measurement at the
