  • Patent number: 9396921
    Abstract: A method and apparatus for conducting the rapid pyrolysis of peptides, proteins, polymers, and biological materials. The method can be carried out at atmospheric pressures and takes only about 5 to 30 seconds. The samples are cleaved at the C-terminus of aspartic acid. The apparatus employs a probe on which the sample is heated and digested components analyzed.

  • Patent number: 9145472
    Abstract: Described are charge reversible polymers, peptides and their resulting colloidal particles, comprising polymers and peptides having primary and secondary amines that are protected as easily hydrolysable amides. The amides are charge-reversible such that at neutral pH they are negatively charged but become positively charged at pH less than 6 and thus are relatively stable at neutral pH but quickly hydrolyze at pH below 6. Incorporating a drug in a micelle or a polymer comprised of the charge-reversible polymers or peptides provides a drug carrier for delivering the drug preferentially to the solid tumor or other targeted cells.

  • Patent number: 8845988
    Abstract: A low-pressure multifunctional filter separates CO2 and other air pollutants from flue, coal, natural and other gas mixtures. The separation agent is a solid carbon-rich sorbent, such as coke, charcoal, coal or activated carbon, that captures CO2 and other air pollutants at lower temperatures and liberates them at higher temperatures. The sorbent is regenerated by heating with direct steam, hot CO2 or other source of thermal energy. The recovered CO2-rich product can be used for enhanced oil recovery, enhanced methane recovery, and subsequent storage in depleted oil and gas reservoirs.

  • Patent number: 7994087
    Abstract: A class of catalysts with unusually high activity for polymerizing vinyl monomers such as acrylates, methacrylates and styrene is described. The catalysts consists of a metal halide such as CuBr and FeBr2 ligated with multidentate amine-based ligands, for example N,N,N?,N?-tetra[(2-pyridal)methyl]ethylenediamine, and additives. The additives, which are tertiary amine compounds, can greatly increase the catalytic activity. The complex is capable of catalyzing a living polymerization reaction at a concentration of the complex below about 0.1 mol %.
