Previous Nature 378, 159 162THE synthesis of mesoporous siliceous solids with largediameter channel apertures (25 has greatly expanded the capabilities of heterogeneous catalysis1 The large apertures in such mesoporous silicas can, for example, エムシーエム バッグ MCM リュック http://www.mcmliveshop.com/ be modified by framework substitution to create MCM バッグ MCM http://www.mcmdayday.com/ highly selective catalysts4,5. Here we show that direct grafting of MCM リュック MCM リュック http://www.mcmstorelive.com/ an organometallic complex onto the inner walls of mesoporous silica MCM41 (ref. 1) generates a shapeselective catalyst with a large concentration of accessible, well spaced and structurally well defined MCM MCM バッグ http://www.mcmdayday.com/ active sites.
The indexing of the Bragg reflections (see inset) is consistent with a bodycentred unit cell with a = 8.4 nm. b, The bicontinuous gyroid minimal surface with pore symmetry. The elemental MCM 財布 MCM 財布 http://www.mcmliveshop.com/ germanium framework follows the gyroid surface and the molecules of surfactant occupy the pore channels.
