A generalized semi 2D-model for the structural transformations under mechanical strains of multi-components transition metal dichacogenide (TMD) monolayers were manipulated. In this model, not only the chemical and structural but also elastic heterogeneity, through the eigen strain method, were introduced. Basing on this model, some experimental observation can be simulated and understood bette...

We report growth of tungsten diselenide (WSe2) nanotubes by chemical vapor deposition with a two-zone furnace. WO3 nanowires were first grown by annealing tungsten thin films under argon ambient. WSe2 nanotubes were then grown at the tips of WO3 nanowires through selenization via two steps: (i) formation of tubular WSe2 structures on the outside of WO3 nanowires, resulting in core (WO3)-shell (...

Transition metal dichalcogenide (TMDC) materials are very important inelectronic and optical integrated circuits and their growth is of great importance in thisfield. In this paper we present growth and fabrication of MoS2 (Molibdan DiSulfide)thin films by chemical bath method (CBD). The CBD method of growth makes itpossible to simply grow large area scale of the thin la...

using uv-vis spectrophotometic method, the formation constants for interaction of cd2+(aq) andco2+(aq) ions with l-alanine were experimentally studied at ph = 4.1 ± 0.01 (50mm of potassiumhydrogen phthalate buffer), ionic strength of 0.1m potassium nitrate and at 5 differenttemperatures 15,20, 25,30 and 35°c. the optical absorption spectra of mixtures containingconsidered cations and l-alanine ...

transition-metal-substituted  (tms)  polyoxometalates  of  the  general  formula  [siw9m3o39], (where m = first row transition metal), has been synthesized and supported on anatase by sol–gel method under oil-bath condition. the tetrabutylammonium (tba) salts of the keggin-type polyoxotungstates  [siw9m3o39],  (m = vii, crii, mnii,  feii coii  and niii),  proved  to  be  green, reusable,  and  ...

The one-third paradigm of PBE0 density functional, PBE0-1/3, has shown to be a successful method for various properties. In this paper, the applicability of PBE0-1/3 is put into broader perspective for transition metals chemistry. As a comparative study, the performance of PBE0 and PBE0-1/3 has been assessed for geometries and vibrational frequencies of some transition metal hydrides and transi...

Transition-metal-substituted  (TMS)  polyoxometalates  of  the  general  formula  [SiW9M3O39], (where M = first row transition metal), has been synthesized and supported on anatase by sol–gel method under oil-bath condition. The tetrabutylammonium (TBA) salts of the Keggin-type polyoxotungstates  [SiW9M3O39],  (M = VII, CrII, MnII,  FeII CoII  and NiII),  proved  to  be  green, reusable,  and  ...

background: combination of glycation and oxidation is associated with diabetes mellitus. the aim of this study was to clarify the effect of glycated proteins in presence of transition metal ions on production of reactive oxygen species (ros) in rat hepatocyte suspension.  methods: glycated albumin was prepared by incubation of bovine serum albumin with 100 mm glucose in 0.3 m phosphate buffer a...
