High transparent conductive indium tin oxide/titanium dioxide (ITO/TiO2) nanostructured thin film is prepared by sol-gel dip-coating technique. This method yielded monodisperse ITO nanoparticles with mean diameter of 12 nm. The atomic composition of the Sn within the ITO structure changed from 0-20 wt.%. Through controlled annealing temperature at 550 oC, the result...

The Sn(IV) atom in the title compound, [Sn(C(4)H(9))(2)(C(9)H(16)NS(2))(2)], is chelated by the two dithio-carbamate ions in a six-coordinate skew-trapezoidal-bipyramidal geometry. The two butyl groups are disordered over two positions in a 1:1 ratio.

background: the dependency ratio (dr) is defined as the ratio of the non-working population to the economically active population. dependency ratio is calculated by the sum of population under fifteen years and over 65 years divided by 15-64 year old population. the interpretation of dr variation gives us the impact of health care services and some reproductive interventions. this study analyze...

The title compound was synthesized by a reactive salt reaction at 773 K over a period of 5 d. It has a one-dimensional chain structure consisting of K(+) cations and one-dimensional [Ag(2)Sn(2)Se(6)](2-) anions. The chain is constructed by edge-sharing bitetrahedral [Sn(2)Se(6)] units connected in a 1:2 ratio via linear Ag(+) ions.

In this contribution, the Co doped SnO2 transparent semi-conducting films are prepared by spray pyrolysis technique and the influence of N2-and Ar-ambient annealing on their structural, electrical and optical properties are studied. The SnO2:Co thin films were deposited on the glass substrate at substrate temperature of 480 ˚C using an aqueous-ethanol solution consisting of tin and cobalt chlor...

OBJECTIVE This study aimed at finding sensitive indicators in diagnosing facial growth pattern by studying the relationship between the indicators which can reflect facial growth pattern according to the previous studies and posterior-anterior ratio. METHODS The cephalometric radiographs of 61 teenage children were measured, the posterior-anterior ratio and the other 12 indicators including Y...

Based on a detailed study of the temperature structure of the intracluster medium in the halo of M 87, abundance profiles of 7 elements, O, Mg, Si, S, Ar, Ca, and Fe are derived. In addition, abundance ratios are derived from the ratios of line strengths, whose temperature dependences are small within the temperature range of the ICM of M 87. The abundances of Si, S, Ar, Ca and Fe show strong d...

We review the observational status of the supernova/gamma-ray burst connection. Present data suggest that SNe associated with GRBs form a heterogeneous class of objects including both bright and faint hypernovae and perhaps also ‘standard’ Ib/c events. Evidence for association with other types of core-collapse SNe (e.g. IIn) is much weaker. After combining the local GRB rate with the local SN-I...
