The processes of formation of polyconjugatcd fragments during thermal oxidation of polymers and the reactions of low molecular compounds yielding polymers with an extended system of conjugation are considered. It is shown from the experimental data that the polyconjugated system (PCS) formed during thermal oxidation and thermolysis exerts initiating or activating action during the process. The ...
the geopolitics of afghanistan after september 11, 2001, and its impact on iranian national security
abstract u.s. attack to afghanistan after 9/11 provided opportunities for us who tried to become the dominant power after collapse of ussr and bipolar world. thinkers like fukuyama believed american liberal democrats thought would be universally accepted without resistances. liberal democracy is the best and final model of governance; in this regard, united state has moral responsibilities for...
In this report, copper iron sulfide nanoparticles with various composition were synthesized by a thermolysis based wet chemical method. These inherently sustainable nanoparticles were then fully characterized in terms of composition, structure, and morphology, as well as for suitability as a thermoelectric material. The merits of the material preparation include a straightforward bulk material ...
We report the large-scale synthesis of uniform-sized hexagonal pyramid-shaped ZnO nanocrystals by the thermolysis of Zn-oleate complex, which was prepared from the reaction of inexpensive and environmentally friendly reagents such as zinc chloride and sodium oleate. Under optimized reaction conditions, we were able to synthesize as much as 2.83 g using 300 mL of oleylamine and 90 mL (284 mmol) ...
Thermolysis of a toluene solution containing [Fe2W(CO)10( 3-S)2] (1) and [( -C5H5)W(CO)3(CCPh)] (2), at 80°C yields the mixed metal cluster [Fe2(CO)6( 3-S)2W{( -C5H5)W(CO)3(CCPh)}2] (3). Structure of 3 has been established crystallographically. It consists of a triangular Fe2W unit, each face of which is capped by a sulfido ligand. Each Fe atom bears three carbonyl groups. Two separate molecule...
Small angle x-ray scattering ~SAXS! measurements were performed on nanoporous methyl silsesquioxane films that were generated by the incorporation of a sacrificial polymeric component into the matrix and subsequently removed by thermolysis. The average pore radii ranged from 1 to 5 nm over a porosity range of ;5–50%. The distribution in pore size was relatively broad and increases in breadth wi...
