In recent days Zinc oxide (ZnO) attracted much interest due to its versatibility and size dependent opto-electronic properties. ZnO flake structures have been hydrothermally synthesized in the reaction of aqueous solution of cetyl trimethyl ammonium bromide (CTAB) and NaOH at 373.15 K. It was found that, the volume of added ammonia, surfactant (CTAB), and mixed solvent play crucial roles in mor...

Diffusion and drift of a graphene flake on a graphite surface are analyzed. A potential energy relief of the graphene flake is computed using ab initio and empirical calculations. Based on the analysis of this relief, different mechanisms of diffusion and drift of the graphene flake on the graphite surface are considered. A new mechanism of diffusion and drift of the flake is proposed. Accordin...

Transition-metal dichalcogenides like molybdenum disulphide have attracted great interest as two-dimensional materials beyond graphene due to their unique electronic and optical properties. Solution-phase processes can be a viable method for producing printable single-layer chalcogenides. Molybdenum disulphide can be exfoliated into monolayer flakes using organolithium reduction chemistry; unfo...

Cobalt Oxide/ Zinc Oxide nanocomposite was synthesized by dropwise addition ofCo(NO)3.6H2O and Zn(NO3)2.4H2O solutions to KOH solution at different temperatures followed bycalcination at 300ºC for 4 h. The morphology and structure of nanoparticles and the influence oftemperature on particle size were studied using scanning electron microscopy (SEM) and X-RayDiffraction (XRD). Minimum particle s...

The thermal conductivity of doped graphene flake of finite size is investigated with emphasis on the influence of the mass of the substituting atoms on this property. It is shown that graphene doping by small concentrations of relatively heavy atoms results in a disproportionately large drop in lattice thermal conductivity.

The results of systematic numerical studies of graphene flakes growth in low-temperature arc discharge plasmas are presented. Diffusion-based growth model was developed, verified using the previously published experiments, and used to investigate the principal effects of the process parameters such as plasma density, electron temperature, surface temperature and time of growth on the size and s...
