Abstract: A polymer compound containing groups having the chemical structure: where NH2 is a primary amine, and R is not hydrogen, and a polymer backbone wherein two of the R groups are part of the polymer backbone. A method of synthesizing a polymer includes polymerizing amine-convertible monomers to produce a polymer, causing a deprotection reaction with the polymer to form an isocyanate, decomposing the isocyanate to form a polymer containing primary amines. A method to separate CO2 from other gases comprising using a sorbent containing a polymer compound having the structure: where NH2 is a primary amine, and R is not hydrogen, and a polymer backbone wherein two of the R groups are part of the polymer backbone.

Abstract: A method to increase the hot carcass weight of a meat-producing animal. The method orally administers Vitamin C to a meat-producing animal between about 2 and about 48 hours prior to harvest. The animal is then harvested and a hot carcass is prepared from that harvested animal.

Abstract: A process chamber configurable for the execution of discrete subprocesses in a substrate coating process such as photolithography. Two vertically staggered rings disposed within the process chamber channel a flow of gas through the chamber and retain fluent chemical within the process environment. A replaceable liner further enables reconfiguration of the chamber. The chamber is used for low-velocity dispensing of fluent process chemical onto the substrate surface with a laminar exhaust gas flow through ventilation passages formed about the rings. The chamber is also used during high-velocity spinning of the substrate for even process chemical distribution in a solvent saturated atmosphere. The ventilation passages enable high exhaust flow through the chamber while minimizing the direct impingement of exhaust air on the substrate.
