Abstract: Electrolysis electrocatalysts and their use in an electrolysis process, for example, in the electrolysis of water, more particularly for producing hydrogen at the cathode of a water electrolyser or producing oxygen at the anode of a water electrolyser, as well as a water electrolyser including such an electrocatalyst. The electrocatalyst includes a combination of palladium and iridium.

Abstract: The present invention relates to a hydrogen, methanol, or ethanol fuel cell comprising an anode electrocatalyst comprising palladium and iridium, and relates to a fuel cell stack comprising said fuel cell. The invention also relates to a method of making a fuel cell. The invention also relates to the use of the anode electrocatalyst in a hydrogen, methanol or ethanol fuel cell.

Abstract: Oral care composition comprising a polymer obtainable by copolymerising a mixture of comonomers, in which at least 40 mol % of the mixture of comonomers is constituted by a comonomer having the formula (I): H2C?C(R)—(X)n—Y in which R is hydrogen or a methyl group, X is a divalent organic linking group, n is an integer of 0 or 1, and Y is a carboxylate or phosphonate anion, or the corresponding salt or acid thereof; and in which the balance of the mixture of comonomers is constituted by neutral and/or cationic comonomers; said composition being in the form of any one of a toothpaste, gel, foam, chewing gum, deformable strip or mouthwash and being suitable for use in the oral cavity.

Abstract: Oral care composition comprising a polymer obtainable by copolymerising a mixture of comonomers, said mixture comprising: (a) a cationic monomer selected from (ar-vinylbenzyl) trimethylammonium chloride, (dimethylaminopropyl) methacrylamide, [2(methacryloyloxy)ethyl]trimethylammonium chloride, 2-aminoethylmethacrylate hydrochloride and mixtures thereof; and (b) at least one anionic or neutral monomer selected from styrene, mono-2-(methacryloyl)ethyl succinate, vinyl acetate, N, N-dimethylacrylamide, 2-ethylhexylacrylate, vinylphosphonic acid, acrylic acid, 2-acrylamido-2-methyl-1-propanesulfonic acid, N-[tris(hydroxymethyl)methyl] acrylamide, N-vinylpyrrolidone, butyl acrylate, 2-hydroxyethylacrylate, polyethyleneglycol methylethermethacrylate and mixtures thereof, said oral care composition in the form of any one of a toothpaste, gel, foam, chewing gum, deformable strip or mouthwash and which is suitable for use in the oral cavity.
