Abstract: A method of purifying a biological composition includes: disposing loose cationic ligand-functionalized staple fibers and a biological composition within a mixing volume of a vessel; agitating the biological composition and the loose cationic ligand-functionalized staple fibers while they are in intimate contact with each other within the mixing volume to provide modified fibers and a purified biological composition; and separating at least a portion of the purified biological composition from the modified fibers and any loose cationic ligand-functionalized staple fibers with which it is in contact. The loose cationic ligand-functionalized staple fibers have a modified surface layer comprising a grafted acrylic polymer comprising 10 to 100 percent by weight of a cationically-ionizable monomer unit. An article for purifying a biological composition includes: a vessel having a mixing volume disposed therein; and the loose cationic ligand-functionalized staple fibers disposed within the mixing volume.

Abstract: The present disclosure relates to porous electrodes, membrane-electrode assemblies, electrode assemblies and electro-chemical cells and liquid flow batteries produced therefrom. The disclosure further provides methods of making porous electrodes, membrane-electrode assemblies and electrode assemblies. The porous electrodes include a porous electrode material comprising a non-electrically conductive, polymer particulate; and an electrically conductive carbon particulate; wherein the electrically conductive carbon particulate is at least one of carbon nanotubes and branched carbon nanotubes. The electrically conductive carbon particulate is adhered directly to the surface of the non-electrically conductive, polymer particulate and at least a portion of the non-electrically conductive polymer particulate surface is fused to form a unitary, porous electrode material.
