We develop metrology to advance nanomaterial research and applications to benefit U.S. commerce. Our world-class measurement science determines the physical and chemical properties of a wide variety of organic, inorganic, biomolecular and hybrid systems, where materials are in the nanoscale regime. Our standards, methods, reference materials and measurement data advance a wide range of technologies and stimulate innovation.
When Babak Nikoobakht arrived at Georgia Tech to begin his PhD studies, he knew the field of research he wanted to devote his academic focus. Babak worked in
If you’ve been to your local beach, you may have noticed the wind tossing around litter such as an empty potato chip bag or a plastic straw. These plastics
Two new Standard Reference Materials from the National Institute of Standards and Technology give researchers and manufacturers a way to check the performance
A new design for light-emitting diodes (LEDs) developed by a team including scientists at the National Institute of Standards and Technology (NIST) may hold the
The goal of this project is to help develop innovative metrologies and measurement protocols for micro/nano-scale analysis of particles.
In this project, state-of-the-art optical and electron-based microscopy are used to conduct research for quantitative and qualitative analysis of chemical
Spectral data from satellite and ground-based remote sensing instruments are used to monitor the effects of atmospheric aerosols on climate. Determinations of how aerosols interact with sunlight or infrared radiation from Earth’s surface rely upon an aerosol model that approximates the sizes, shapes
The lasing capabilities and piezoelectric properties of single ZnO nanowires offer promise for future technologies. However, the photoluminescence of ZnO nanowires differs depending upon the synthesis method and the defects present in the sample. This project was undertaken to characterize zinc
Intended Impact Due to the complexity of how solar energy interacts with atmospheric particles, large uncertainties exist in predictions of the effect of aerosols on climate. A critical component in reducing the these uncertainties is the accurate determination of the particle single-scattering

Using dendron chemistry, we developed stability-enhanced carboxylate surfacemodified (negatively charged dendron) AuNPs (Au-NCD). Since the carboxylate surface
The Nova NanoLab 600 (NNL600) is a Focused Ion Beam Scanning Electron Microscope equipped with spectroscopic detectors to allow elemental and phase measurements
"An innovative fin-shaped design for light-emitting diodes (LEDs) could not only overcome the devices’ limited brightness, it could also help turn them into
