Control of the morphology of crystalline calcium hydroxide
(2001)The reaction of solid calcium hydroxide with liquid or gaseous methanol, ethanol and toluene, and the effect this has on the surface properties of the solid was examined, as well as the modification of crystal habit by the ...

The effect of sorbed toluene on the surface properties of calcium hydroxide
(1998)The surface properties of commercial grade calcium hydroxide were studied by nitrogen adsorption isotherm analysis, FTIR spectroscopy (KBr transmission and reflectance) and TGA analysis before and after toluene adsorption. ...

Investigation of the synthesis and properties of ternary V-Cu-Ce Oxides of Composition VxCuxCe1-2xO2
(2009)Aco-precipitation method has been used to prepare ternary mixed oxides based on ceria with the general formula VxCuxCe 1-2xO2, where x was varied between 0.05 and 0.45. The structural and surface properties as well as the ...

Large positive magnetoresistance in nonstoichiometric NiMnSb thin films on silicon
(2004)The transport properties of pulsed-laser-deposited NiMnSb films on silicon as a function of film thickness were discussed. It was found that a low-temperature upturn was observed in the resistivity for film thicknesses of ...

Polymeric nanowires and nanopillars fabricated by template wetting
(2013)Template wetting constitutes a common technique for the fabrication of elongated polymeric nanostructures such as nanorods, nanotubes, and nanowires. It is based on the infiltration of polymeric solutions inside the nanopores ...

Preparation and characterization of a cerium(IV)-incorporated manganese oxide OMS-2. Effect of cerium(IV) template on octahedral molecular sieves of manganese oxide and characterization of manganese oxide molecular sieves with cerium(IV) as dopant
(2008)The manganese oxide material K-OMS-2 was synthesized both via a redox reaction between potassium permanganate and manganese nitrate in an acidic medium (nitric acid) under reflux conditions and by the sol-gel reaction ...

Reforming of methane with carbon dioxide to synthesis gas over supported Rh catalysts
(1994)Reforming of methane with carbon dioxide to synthesis gas (CO/H2) has been investigated over rhodium supported on SiO2, TiO2, γ-Al2O3, MgO, CeO2, and YSZ (ZrO2 (8 mol% Y2O3)) catalysts in the temperature range of 650-750°C ...

Surface particularities in pulsed laser ablation/deposition of the ferromagnetic alloy NiMnSb
(2003)In this work we investigate the surface morphology and stoichiometry of the ablated targets employed with pulsed laser deposition (PLD) of thin films of the ferromagnetic half-Heusler alloy NiMnSb. The NiMnSb targets were: ...

Synthesis and characterization of mesoporous cerium oxide prepared using an organic base and a templating agent
(2008)This paper discusses the effect on the surface properties of precipitated cerium oxide of using a mixed alcohol-water solvent as well as an organic base instead of the ammonia solution used hitherto. It further discusses ...

Velocities for moving random surfaces
(2003)For a stationary two-dimensional random field evolving in time, we derive statistical distributions of appropriately defined velocities. The results are based on a generalization of the Rice formula. We discuss importance ...
