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
Advanced microscopy and spectroscopy techniques are used in this project to study the chemical and physical properties of particles contained in complex
Atmospheric aerosol particles often have compositions and shapes that cannot be described as a single material phase within a simplified geometric form such as
ZnO nanowires (NWs) are grown on bulk copper by chemical vapor deposition. Photoluminescence (PL) microscopy revealed band gap emission at 380 nm and a more
Atmospheric particles with long atmospheric lifetimes affect Earth's radiative balance. These particles typically consist of multiple chemical species. The

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
