Abstract:
Provided herein are materials and methods of reducing contamination in a biological substance or treating contamination in a subject by one or more toxins comprising contacting the biological substance with an effective amount of a sorbent capable of sorbing the toxin, wherein the sorbent comprises a plurality of pores ranging from 50Å to 40,000Å with a pore volume of 0.5 cc/g to 5.0 cc/g and a size of 0.05 mm to 2 cm and sorbing the toxin. Also provided are kits to reduce contamination by one or more toxins in a biological substance comprising a sorbent capable of sorbing a toxin, wherein the sorbent comprises a plurality of pores ranging from 50Å to 40,000Å with a pore volume of 0.5 cc/g to 5.0 cc/g and a size of 0.05 mm to 2 cm and a vessel to store said sorbent when not in use together with packaging for same.
Abstract:
The present invention relates to a method of preparing porous solids, which method comprises polymerizing, in a salt melt or a eutectic mixture of salt melt containing at least one Lewis acidic salt, cyano monomers having at least one or at least two cyano groups in their molecule, wherein the at least one or at least two cyano groups are bonded to a rigid linking group in the cyano monomer, as well as to the porous solids obtainable by that method. Owing to their porosity and the associated extremely high specific surface area, the porous solids are useful as sorbents, filtering and insulating materials, as well as catalyst carriers.
Abstract:
The invention relates to microporous films obtained by mixing A) 55 to 99.9 wt. % thermoplastic polyamides with B) 0.1 to 10 wt. % of a salt having a solubility in water of > 5 g/100 ml at 80 DEG C and optionally C) 0 to 30 wt. % further additives, whereby the sum of the weight percentages of constituents A) to C) equals 100 %. The invention also concerns the production of a film using standard flat sheet extrusion or blown film methods and subsequent aqueous extraction of constituents B).
