Abstract: Porous ceramic catalyst supports are pre-coated with a passivation layer prior to applying a catalyst or catalyst support coating, the passivation layer consisting of a coating of a liquid mixture comprising at least one coating material selected from the group of polyvinyl alcohol/vinyl amine copolymer, polyvinyl alcohol/vinyl formamide copolymer, and gelatin.

Abstract: A multiwell plate is described herein that can be used in cell-based applications and is made from a plastic upper plate which forms the sidewalls of one or more wells and a glass lower plate which forms the bottom walls of the wells. The plastic upper plate and glass lower plate are attached and bound to one another by a cationically photocured adhesive. A preferred cationically photcured adhesive includes: (1) one or more photocationally polymerizable epoxy and/or oxetane functional resins; (2) a low fluorescing cationic photoinitiator; and (3) a low fluorescing photosensitizer if the cationic photoinitiator does not have an adequate absorption at a wavelength >280 nm to initiate cure. Also described herein is a method for making such multiwell plates.
