In critical cleaning for medical, dental, electronic, and pharmaceutical applications, the priority is movement of the water mass without leaving non-aqueous residues (water spots). That’s why evaporation is often a poor approach toward removing water—non-volatile minerals get left behind as water spots.
While there have been improvements in materials and methods of ESD control over this period and some factories have done a better job than others in implementing them, the fundamental capability of the methods has not changed appreciably.
This event provided fascinating perspectivesregarding trends in industrial processes related to biomedical devices (specificallyin standardization efforts), the merging of device and drug, areas of commercialemphasis, and the acute concern of workshop attendees with cleaning and contamination control.
Following challenge studies, there is a need to decontaminate the Challenge Room and its contained BFS machine. Given the nature of the Challenge Room and the complex construction of the BFS machine, chlorine dioxide gas waschosen for decontamination purposes.
Dakota State University launched the Center for Nanoscale Science and Engineering with the mission of engaging in pioneering, interdisciplinary research, and technology development on materials whose functional design starts at the atomic-molecular scale.
Because computer chips are so susceptible even to the tiniest speck of dust, cleanrooms, historically, have been difficult areas to protect from fires. Contamination from a fire, no matter how small, could potentially put a chip maker out of business for weeks—if not permanently.
It was a time when we took a chance for us all. We, the US and 24 other countries, choose to believe the then-immature atmospheric science, abandon a highly-sophisticated and profitable technology, form an agreement called the Montreal Protocol (MP), and accept the unknown in order to "save the planet."
In this investigation, the applicability of the techniques, Mercury Intrusion Porosimetry, Liquid Extrusion Porosimetry, and Liquid Extrusion Flow Porometry for pore structure characterization of nanofiber mats have been investigated. The results obtained by the three techniques have been critically examined.
A manufacturing manager for a biotech firm told me that they use a phenolic disinfectant exclusively for one month and then switch to a bleach solution for one month. He said he was not really sure where the rationale originated, but knew that it had been validated.
