Abstract: Improved methods for drying for bio-compatible solid phase microextraction (BioSPME) coatings yielding coatings with highly consistent extraction efficiency and biocompatibility. The methods, adapted to flow-through drying systems involve determining relative humidity in and around the drying system, determining a drying temperature range based on the relative humidity, and maintaining the drying temperature within the determined range while drying the coating.

Abstract: A durable pollution control systems, articles, and methods for removing multiple flue gas pollutants. The pollution control system includes an article comprising a sorbent polymer composite (SRC), and a plurality of halogen reservoirs. In some, the halogen reservoirs are embedded within the SRC. In some, each of the halogen reservoirs has 5 wt % to 95 wt % of at least one permeation control material based on an average weight of each halogen reservoir and 5 wt % to 50% of at least one halogen source based on an average weight of each halogen reservoir.

Abstract: A method for producing a chromatography medium by:



a) exposing a nanoweb sheet having mean flow pore size from 0.1 to 5 μm and a porosity from 40 to 90 volume % to a gaseous phase comprising a vinyl monomer to produce a functionalized nanoweb sheet;
b) layering a plurality of functionalized nanoweb sheets to form a functionalized nanoweb stack;
c) cutting the functionalized nanoweb stack with a die to form die-cut functionalized nanoweb stacks having regular shapes; and
d) exposing the die-cut functionalized nanoweb stacks in an aqueous medium to a ligand such as a protein which is capable of forming covalent bonds.

Abstract: A disposable, virus-trapping membrane, and a corresponding method to remove viruses from solution are described. The membrane includes a disposable, micro-porous filter membrane and a ligand immobilized on the membrane. The ligand irreversibly and selectively binds viruses. The ligand also has a pKa sufficiently high to repel antibodies via electrostatic charge repulsion.
