The COVID-19 pandemic necessitated the evaluation of commercial air purification units to protect worker safety in indoor spaces. This project evaluated the efficacy of commercial offthe-shelf air purification systems that utilize electrostatic precipitation for the collection and removal of particulates (including bioaerosols) from ambient air.

Deuterium (D), which is found in natural water at ~ 150 ppm, seems to play an important role in biology; however, research in this field has likely been stalled by the limited availability of D2O with varying D concentrations needed to accurately study the deuterium effects in biological systems. SRNL can currently manufacture D2O in varying concentrations, and we have assembled an interdisciplinary research group to study cell cycle in human normal and cancer cells as a function of D concentration over time in order to address several fundamental science questions.
