Abstract: Disclosed are terpolymer adhesives comprising three different repeating domains: a catechol containing domain, a zwitterionic domain, and a crosslinking domain. In specific examples, the polymer can contain a 3,4-dihydroxy-L-phenylalanine (DOPA) segment which contains a catechol group, a poly(sulfobetaine methacrylate) (polySBMA), and poly(ethylene glycol) dimethacrylate (PEGDMA) for light crosslinking. Alternatively, a photocleavable nitrobenzyloxycarbonyl containing crosslinker can be used. The disclosed polymers can be used as biomedical adhesives, such as to prevent leakage from the sutured intestinal tissue.

Abstract: A method for separating a homogeneous catalyst from a solution includes forming a host-guest compound between a first isomer of the catalyst and inclusion compound in the solution and isolating the host-guest compound from the solution. The catalyst may be released from the inclusion compound by converting the first isomer of the catalyst to a second isomer of the catalyst.

Abstract: A chemical reaction is catalyzed in an organic solvent using a water soluble N-heterocyclic carbene homogeneous catalyst to form a reaction mixture. An aqueous phase in the reaction mixture. A solvent in which the catalyst is insoluble is added to the reaction mixture, causing the catalyst to migrate to the aqueous phase to form a catalyst-laden aqueous phase. The catalyst is extracted from the catalyst-laden aqueous phase.
