Two novel synthesis routes for the preparation of mesoporous MCM-41 materials are introduced. Both methods use tetra-n-alkoxysilanes such as tetraethoxysilane (TEOS) or tetra-n-propoxysilane (TPS

The present invention is related to a family of white clinker compositions with a high capacity of fixing sulfur coming from a high sulfur content pet-coke used as fuel, which further exhibits low fuel consumption and fast setting, which comprises the amounts of clinker phases in percentage by weight: 3CaO.SiO 2 (C 3 S): 40 to 75, 2CaO.SiO 2 (C 2 S): 10 to 35, 3CaO.Al 2 O 3 (C 3 A): 0 to 15
2019-3-21 · Metal species with different size (single atoms, nanoclusters, and nanoparticles) show different alytic behavior for various heterogeneous alytic reactions. It has been shown in the literature that many factors including the particle size, shape, chemical composition, metal–support interaction, and metal–reactant/solvent interaction can have significant influences on the alytic
Ce1-xMnxO2 (x = 0.05, 0.075 and 0.1) nanoparticles were synthesized by simple solution method using cerium(III) nitrate hexahydrate manganese (II) nitrate hydrate (Mn(NO3)2∙H2O) and freshly extract egg white (ovalbumin) in an aqueous medium. The precursors were calcined at 600 °C for 2 h in air.
