The Group performs fundamental research and develops metrology towards the compositional and morphological characterization of materials from the mesoscale to the atomic scale using electron, ion, and photon interactions with matter; detailed measurements, comprehensive analysis and modeling, and theoretical methods serve to advance microanalysis to address stakeholder needs in diverse areas of materials science.
Because of their antimicrobial and antifungal properties, silver nanoparticles measuring between one and 100 nanometers (billionth of a meter) in size, are
By capping liquids with graphene, an ultrathin sheet of pure carbon, researchers at the National Institute of Standards and Technology (NIST) and their
Electron, ion and photon-based microanalysis methods, instrumentation and protocols are developed to advance measurement science towards the elemental and
Advanced experimental and theoretical methods are developed to increase the accuracy and precision of X-ray line energies and information derived from X-ray
Electronic structure information obtained with photoemission-based measurements provides a keystone in understanding emerging quantum materials, and the unique
Organic photovoltaic cells rely upon molecular interfaces to separate charge. Efficient charge separation depends on molecular structure and electronic band
The mission of the Micro and Nanoplastic (MNP) Metrology Project is to assist regulators in assessing the human health and environmental risks associated with
