The detection of low energy charged particles is essential to high precision fundamental physics experiments, particularly with neutron beta decay. The majority
Spectroradiometers are widely used for acquiring colorimetric, photometric, and radiometric quantities with a single measurement for a variety of applications
The capabilities of many neutron scattering instruments would be greatly enhanced by neutron polarization analyzers that can cover a wide angular range.
Operation of the second neutron radiative decay experiment was completed. In the experiment we observed the emission of photons that accompany neutron beta
The National Institute of Standards and Technology operates two spectral comparator facilities, both of which are used to provide detector calibrations from the
The ASM Structural Materials Data Demonstration Project SMDDP) is a cooperative research project with the NIST Materials Measurement Laboratory (MML) that is
Due to their small size, nanoparticles can enter living organisms in previously unforeseen ways and their immense surface area results in higher reactivity
Atmospheric particles with long atmospheric lifetimes affect Earth's radiative balance. These particles typically consist of multiple chemical species. The
Damage to concrete structures in residential and commercial construction in central Connecticut have been attributed to the iron sulfide mineral pyrrhotite
While it is a key aspect of structural analyses that support current Performance-Based Seismic Engineering (PBSE), "structural collapse" is not clearly defined
The use of thermal insulation is a primary approach to reducing heating and cooling loads in buildings, which account for 42 % and 24 % of energy consumption in
In this work, a family of asynchronous cooperative linear dispersion codes (ACLDCs) capable of maintaining full diversity in cooperative scenarios have been
At the heart of nanotechnology is the need to create nanostructures, which are material structures whose dimensions are in the nanometer scale. Typically
The semiconductor industry requires sub-nanometer, 3-dimensional quantitative elemental mapping of materials, nanoscale structures, and devices with high
