Abstract: An electrode for an electrochemical cell is presented which comprises a substrate and an electrode material. The electrode material comprises an electrocatalyst and a solid glass phase which binds the electrocatalyst to the substrate. The electrodes of the invention are durable and can be produced by a much simpler, faster technique than is required for preparing conventional electrodes and can incorporate a wider range of electrocatalytic materials.

Abstract: An apparatus is provided for the catalytic treatment of exhaust gas from an internal combustion engine comprising: a. a casing having an exhaust gas inlet and a treated exhaust gas outlet; b. a heater disposed within the casing, through which exhaust gas may flow; and c. a catalyst article disposed within the casing adjacent to the heater, through which exhaust gas can flow; wherein the heater comprises an electrically resistive wire mounted on an electrically insulating frame.

Abstract: A complex compound comprising the skeletal unit of Formula A, wherein the ring represented by C(R1)-A1-A2-(A3)x-C(R2)—C— has delocalised unsaturation and is optionally substituted via one or more of A1, A2 and A3 with atoms or groups selected from hydrogen, alkyl, aryl, halogen, or heterocyclic groups containing at least one N, S or O in a carbon ring; A1, A2 and A3 are selected from carbon, nitrogen or oxygen, R1 and R2 are each selected from chlorine, bromine or iodine; x is zero or 1, O is oxygen, E is nitrogen, phosphorus or arsenic, Q represents a divalent bridging group comprising one or more Group 14 atoms; M is a metal selected from Groups 3 to 7; X represents a monovalent atom or group covalently or ionically bonded to M; L is a mono- or bidentate molecule datively bound to M, y satisfies the valency of M and z is from 0 to 5. The complex can be used to polymerise olefins optionally with organo-A1 or -B compounds as activator.
