a organic-solution-processable functionalized-graphene (spfgraphene) material has been studied on pre-concentration and determination of trace mo(ii)ions. in this process, the effects of ph solution, elution conditions on pre-concentration of trace mo(ii) were studied and the effect of interfering ions was also investigated. a selective method for the fast determination of trace amounts of mo (...

microporous hydroxy-sodalite zeolite membranes with different morphologies were synthesized via secondary growth technique with vacuum seeding on tubular α-al2o3 supports at two different synthesis conditions (i.e. two different routes). microstructures of the synthesized membranes were characterized by x-ray diffraction (xrd), scanning electron microscope (sem) and single gas permeation using ...

in this work, we report, optical properties of cd1-xsnxte quantum dots (x= 0.05, 0.10 and 0.15) synthesized in water using thioglycolic acid (tga) as a modifier agent. the optical characterization of the samples was performed through absorption (uv) and photoluminescence spectra (pl). a red shift absorption and fluorescent emission peaks was observed which can be related to the increase of nano...

Experiments on the hydrogenation of CO on crystalline and amorphous ice at 15 K were carried out to investigate the structural effects of the ice surface. The effective rate of H atom addition to CO on the amorphous ice was found to be larger than that on the crystalline ice, while CO depletion on crystalline ice became larger after long exposure. We demonstrated that the CO-coverage on the ice...
