Sorry, no etymologies found.
Kimmel and his co-authors, working at the PNNL-based W.R. Wiley Environmental Molecular Sciences Laboratory, tested the theory with a technique called rare gas physisorption that enlists krypton to probe metal surfaces and water layers on those surfaces.
The PICO-TRAP System combines the principles of chemisorption and physisorption to achieve higher levels of process gas purity than by conventional purification technologies, according to the company.
