EV Battery Passport

Completed
End-of-life issues associated with EV batteries (EVBs) are estimated to have a steep rise in the coming decades. Given the finite nature of material resources worldwide, developing a circular EV batteries (EVB) infrastructure is needed to keep high value battery materials in the economy, therefore

A Comparison of WD-EPMA Heterogeneity Testing Procedures

Ongoing
X-ray stage mapping (XSM) can be used to determine the extent of heterogeneity on the micron scale though it is more time consuming and not as accurate as the more rigorous NIST random-point (RP) testing procedure. The objective of this work is to demonstrate the advantage of the latter procedure

Diffraction Metrology and Standards

Ongoing
Diffraction techniques can provide data on a number of sample characteristics. Therefore, the method of certification and the artifact itself are chosen to address a specific measurement issue pertinent to a diffraction experiment. NIST diffraction SRMs may be divided into five groups: Line Position

Drug Analysis - Opioids and Emerging Threats

Ongoing
Package Interdiction Many synthetic opioids and novel psychoactive substances enter the country through international mail. Research in this area focuses on measurement challenges associated with detection and analysis of these packages at the point of seizure in international mail facilities

Electronic Structure and Dynamics in Quantum Materials

Ongoing
Photoemission-based methods that interrogate solid state electronic structure have played a pivotal role in identifying and understanding key features of emerging materials. Band structure information from Angle-Resolved PhotoEmission Spectroscopy (ARPES) provided the first evidence for the d-wave
