Responsive copolymers for enhanced petroleum recovery. Quarterly technical progress report, September 22, 1993--December 22, 1993

Description: Synthetic efforts have focused on the development of ionically modified polymers based on monomers which contain an acrylamido functionality. The monomers may possess either cationic or anionic functionality which, depending on the pH of the polymer solution, may either be ionically charged or neutral. Thus, by adjusting the pH, the degree of ionization of the polymer may be controlled which will in turn influence the rheological behavior. Previous research in our laboratories has revealed that… more

Genetic manipulation of a cyanobacterium for heavy metal detoxivication

Description: Increasing heavy metal contamination of soil and water has produced a need for economical and effective methods to reduce toxic buildup of these materials. Biological systems use metallothionein proteins to sequester such metals as Cu, Cd, and Zn. Studies are underway to genetically engineer a cyanobacteria strain with increased ability for metallothionein production and increased sequestration capacity. Cyanobacteria require only sunlight and CO{sub 2}. Vector constructs are being developed in… more
