Abstract: A method for manufacturing a composite electrode for a metal-air electrochemical cell with a liquid electrolyte of basic pH. A liquid solution comprising a fluoropolymer suspended in a solvent is synthesized, then deposited on the outer surface of a porous structure forming an air electrode. The fluoropolymer comprises SO2N groups suitable for conducting hydroxyl ions and is capable of forming a membrane impermeable to at least the liquid electrolyte of basic pH. When the liquid solution is applied to the porous structure, the solvent flows through the porous structure and the fluoropolymer is deposited by aggregating into a layer on the outer surface of the porous structure.

Abstract: A rechargeable battery including a casing containing therein: an air electrode; a negative electrode; and an electrolyte, in which the air electrode can be taken out of the casing. The rechargeable battery also relates to a cathode compartment for an air electrode battery, where the compartment includes an air electrode and is insertable into a casing of the battery without being part of the casing, and the compartment is removably movable.

Abstract: A cell culture microcarrier includes a polymer formed from copolymerization of a mixture including (i) an uncharged hydrophilic unsaturated monomer having a hydroxyl group; (ii) a hydrophilic carboxylic acid containing unsaturated monomer; and (iii) a hydrophilic multifunctional unsaturated monomer. The microcarrier may further include a polypeptide, such as a polypeptide that promotes cell adhesion, conjugated to the surface of the microcarrier; e.g. via the carboxyl group from the hydrophilic carboxylic acid containing unsaturated monomer. Some of the microcarriers support attachment of human embryonic stem cells.

Abstract: A cell culture polysaccharide microcarrier includes (1) a cross-linked polysaccharide microcarrier base having a neutral or negative charge at pH 7, and (ii) a polypeptide conjugated to the base. The polypeptide may contain a cell adhesive sequence, such as RGD. Cells cultured with such microcarriers exhibit peptide-specific binding to the microcarriers.
