Hexakis(urea-κO)zinc(II) dinitrate at 110 and 250 K: uniaxial negative thermal expansion.
The crystal structure of the title compound, [Zn{CO(NH(2))(2)}(6)](NO(3))(2), has been determined at 110 and 250 K. The structure is stabilized by 12 individual hydrogen bonds, both intra- and intermolecular. Analysis of the thermal expansion tensor, based on unit cells determined over a temperature range of 180 K, shows uniaxial compression in the direction of the b axis during warming. The hy...
متن کاملStructural, Optical and Thermal Studies on Zinc Sulfide Nanorods and Manganese Sulfide nanoparticles
Nano sized ZnS and MnS2 were synthesized through a simple wet chemical route. In this Synthesis metal sulfides were used as the starting material and allowed to react with the transition metal source at 60°C for 75 minutes. The products were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Photoluminescence spectra (PL), Raman Spectra, Thermogravimetry analysis Diff...
متن کاملNegative thermal expansion of diamond and zinc-blende semiconductors.
Experimentally it is well known that diamond and zinc-blend semiconductors show an "unusual" (i.e. , negative) thermal expansion at about 100 K. We performed density-functional-theory calculations of thermodynamic potentials (i.e. , total energies and entropies) for perfect crystals, to study the temperature dependence of the lattice parameter. The origin of the negative expansion eff'ect is tr...
متن کاملThermal expansion of natural orthoenstatite to 1473 K
The volume thermal expansion of powdered natural orthoenstatite [(Mg0.994Fe0.002Al0.004)2(Si0.996Al0.004)2O6] has been measured to 1473 K using energy dispersive synchrotron X-ray diffraction. Over the temperature range examined, the data are consistent with a volume thermal expansion, , that linearly increases with temperature as given by the expression (T) = 29.7(16) x 10-6K-1 + 5.7(11) x 10-...
متن کاملElectrochemical Synthesis and Characterization of Zinc Sulfide Nanoparticles
Electrosynthesis process has been used for preparation of zinc sulfide nanoparticles. Zinc sulfide nanoparticles in different size and shapes were electrodeposited by electrolysis of zinc plate as anode in sodium sulfide solution. Effects of several reaction variables, such as electrolysis voltage, sulfide ion concentration as reactant, stirring rate of electrolyte solution and temperature on p...
