Dimethyldichlorosilane Hydrolysate as a Substitute for Cyclic Monomers in the Preparation of Functional Poly(siloxane)s
(Trans Tech Publications Ltd., 2004)
A number of carboxypropyl- terminated poly(siloxane)s were prepared using equilibration
polymerization reactions. Dimethyldichlorosilane hydrolysate, DDSH, was applied as a substitute
for the otherwise used cyclic siloxane ...
Thermal diffusivity of NTC lasers obtained by photoacoustic technique
(Emerald, 2004)
The thermal diffusivity of thick film NTC layers based on a metal oxide powder mixture was measured at room temperature by the photoacoustic (PA) technique. The powder mixture was composed of MnO (60 percent), CoO (32 ...
Structural analysis of conformational flexibility in (aqua) (propanediamine-N,N'-diacetato-N-propionato)chromium(III) dihydrate. Crystal structure of cis-polar, trans(H2O, O-5)-[Cr(1,3-pddap)(H2O)]center dot 2H(2)O
(Taylor & Francis Ltd, Abingdon, 2007)
The quinquedentate complex trans(H2O,O-5)-[Cr(1,3-pddap)(H2O)].2H(2)O (where 1,3-pddap is the 1,3-propanediamine-N, N '-diacetate-N-3-propioriate ion) was prepared and its structure established by X-ray diffraction method. ...
Anisotropy in thermal and electronic properties of single crystal GaSe determined by the photoacoustic method
(EDP Sciences, 2005)
Anisotropy in thermal and electronic properties for two directions of thermal wave propagation in the GaSe single crystal was investigated using photoacoustic (PA) frequency transmission techniques. First, the electric ...
Photoacoustic determination of thermal and electron transport properties of single crystal NiO
(EDP Sciences, 2005)
Thermal and electron transport properties of single crystal NiO were determined using the photoacoustic technique. NiO single crystals were prepared using the Verneuil method and were easily cleaved parallel to the (100) ...
Investigation of the thermal diffusivity of thick film NTC layers obtained with the photoacoustic method
(EDP Sciences, 2005)
The thermal diffusivity of thick NTC layers based on a metal oxide powder mixture was measured at room temperature by the photoacoustic (PA) frequency transmission technique. The experimental PA amplitude and phase diagrams ...
Yb3+ doped dyphillosilicates prepared by thermally induced phase transformation of zeolites
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Yb3+-doped Ba and Sr diphyllosilicates (hexacelsians) have been synthesized using the Na form of LTA zeolite by ion-exchange procedure and thermal treatment. The crystal structures of both doped samples are refined and ...
The effect of the structure of mixed tetraoxanes on their chromatographic behavior on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2004)
The retention behavior of 29 biologically active compounds, mixed 1,2,4,5-tetraoxanes, has been investigated by thin-layer chromatography on unmodified silica, CN-silica, and RP-18-silica. The binary mobile phases ethyl ...
Hydrogenation of soybean oil over Ag-Ni/diatomite catalysts. Effect of silver content on the cis/trans isomerization selectivity
(Materials Science Forum, 2006)
Silver promoted nickel catalysts supported on diatomite were prepared by precipitation method. Characterization of the catalysts prepared with different silver contents (0.1-4.0 wt%) included AAS, XRD, Hg porosimetry, BET ...
Infrared properties of sintered α-MnSe
(De Gruyter, 2006)
Far-infrared reflection spectra of sintered α-MnSe were measured at room temperature. The measured spectrum had one pronounced peak in accordance with literature data and group theory estimation and one smaller peak resulting ...
