Abstract: A system and method for solid phase chemical synthesis reduces the overall amount of solvent required for the process. In, for example, solid phase peptide synthesis, during deprotection of the bound peptide, a deprotecting agent, such as piperidine in dimethylformamide (DMF) is introduced to the reaction vessel. After deprotection is complete, pure DMF, or other similar wash solvent, is used to wash away the residual piperidine from the reaction vessel. The used wash solvent can be removed from the reaction vessel, warmed to evaporate off the piperidine, and the purified used wash solvent can be cooled and re-introduced into the reaction vessel for a subsequent washing. Thus, instead of using six volumes of DMF for washing six times, for example, a single volume of DMF can be used, purified and reused, thus substantially reducing the volume of DMF needed for washing the deprotecting agent from the reaction vessel.

Abstract: This invention relates to a power recovery process in waste steam/CO2 reformers in which a waste stream can be made to release energy without having to burn the waste or the syngas.

It also relates to control or elimination of the emissions of greenhouse gases in the power recovery process of this invention with the goal of producing energy in the future carbonless world economy.

Abstract: A sanitizing cabinet system includes ozone distribution passaging in open fluid communication with a sanitizing compartment inside a cabinet. An ozone generator and a sanitizing air mover are located in the ozone distribution passaging. The sanitizing air mover moves air from the sanitizing compartment across the generator to form ozonated air and moves the ozonated air from the ozone distribution passaging into the sanitizing compartment. A control system controls the ozone generator and air mover based on feedback from an ozone sensor indicating ozone exposure over time. An ozone conversion device is mounted on a dividing wall of the cabinet outside the sanitizing compartment. The dividing wall has inlet and outlet holes, and the ozone conversion device has upstream and downstream chambers in communication with the inlet and outlet holes. Selectively openable dampers separate upstream and downstream chambers from an ozone conversion chamber in which ozone conversion catalyst is received.
