copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [cu3(btc)2] (1) and [cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400, 500, and 600°c. it has also been found that the reaction temperature pla...
a novel complex of cadmium (ii) [cdl0.5(no3)(h2o)](1), l= n,n-bis (o-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by ir, 1hnmr spectroscopy, x-ray powder diffraction (xrd) and scanning electron microscopy (sem). the gray single crystal of compound 1 has...

Ethane 1,2-diamineborane (EDAB) is an alkyl-containing amine-borane adduct with improved hydrogen desorption properties as compared to ammonia borane. In this work, it is reported the high temperature thermolytic decomposition of EDAB. Thermolysis of EDAB has been investigated by concomitant thermogravimetry-differential thermal analysis-mass spectrometry experiments. EDAB shows up to four H₂ d...

Thermolysis of waste plastics in an inert atmosphere has been gazed at as a useful method, because this technique can convert waste plastics into hydrocarbons that can be used either as fuels or as other valued chemicals. In this work, waste polyethylene (PE) was chosen as the raw material for thermolysis. A well designed semi batch reactor has been used for thermolysis of waste polyethylene (P...
[60]Fullerene-fused pyrazolines 1 were prepared by the reaction of C60 with alky diazoacetates under the solid-state high-speed vibration milling conditions as well as in toluene solution. Pyrazolines 1 were stable in refluxing toluene and its thermolysis process in 1,2-dichlorobenzene was investigated, the decomposition rates and activation energies of pyrazolines 1 were obtained. The current ...
A novel synthetic route to polymer-coated ferromagnetic colloids of metallic cobalt has been developed. Well-defined end-functional polystyrenes were synthesized using controlled radical polymerization and used as surfactants in the thermolysis of dicobaltoctacarbonyl to afford uniform ferromagnetic nanoparticles. The presence of the polymer shell enabled prolonged colloidal stability of disper...
