PROCESS FOR PREPARATION OF CHROMATOGRAPHY MEMBRANES
A method for producing a chromatography medium by: a) exposing a nanoweb sheet having mean flow pore size from 0.1 to 5 m 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.

POROUS CYCLODEXTRIN POLYMERIC MATERIALS AND METHODS OF MAKING AND USING SAME
A nucleophilic substitution reaction to crosslink cyclodextrin (CD) polymer with rigid aromatic groups, providing a high surface area, mesoporous CD-containing polymers (P-CDPs). The P-CDPs can be used for removing organic contaminants from water. By encapsulating pollutants to form well-defined host-guest complexes with complementary selectivities to activated carbon (AC) sorbents. The P-CDPs can rapidly sequester pharmaceuticals, pesticides, and other organic micropollutants, achieving equilibrium binding capacity in seconds with adsorption rate constants 15-200 times greater than ACs and nonporous CD sorbents. The CD polymer can be regenerated several times, through a room temperature washing procedure, with no loss in performance.
