About
The CRG is the only academic research group in the USA that is dedicated to the art, science, and technology of precision cleaning.
We offer research, information, and training on the following:
- vapor degreasing
- ultrasonic cleaning
- vacuum cavitation cleaning (also known as Cyclic Nucleation process (CNp) and Vacuum Cycle Nucleation (VCN))
- solvent blend formulation
- aqueous cleaner formulation
- particulate contamination/characterization/removal
- physical property measurement methods
- cleaning trials
- cleanliness verification
The “art” of precision cleaning is found in the CRG’s research methods, inventions, papers, workshops, videos, and webinars.
Dr. Williams’ first cleaning project was in 1998 for the US Department of Energy’s Pantex Plant researching flammable solvent substitution for the cleaning of sensitive metal surfaces. He continued this niche of cleaning research in academia by forming the Cleaning Research Group consisting of him and his students.
Students in the CRG have gained practical skills, industrial knowledge, and a get-it-done attitude. This has led them to success in graduate studies and in careers as chemistry teachers, industrial chemists, and government lab chemists.
Over the years, we have had amazing support from external partners.
