  Size Dependent Fluorescence Decay Dynamics of MoS2 Nanoflakes

  By Jyoti Shakya, Vijendra Kumar

  Abstract: This paper reports a profound method to prepare MoS2, and the effect of ultraviolet light irradiation on its emission characteristics. The exfoliation of molybdenum di-sulfide (MoS2) in a liquid phase has been achieved successfully via probe sonication for different time intervals followed by centrifugation method. Ultraviolet–visible (UV–vis) spectra of the obtained MoS2 dispersions at different exfoliation time indicate that the concentration of MoS2 nanosheets as well as MoS2 quantum dots …

  Role of Filler-Polymer Interface on the Thermal Conductivity in Polymer Composites

  By Vijendra Kumar, Abhishek Barnwal, R. K. Shukla, Jyoti Shakya

  Abstract: Polymers with high thermal conductivity are the need of modern technologies due to their robustness, cost-effective, and less corrosiveness. However, bare polymers are not good heat-conductors due to their molecular structures, and their non-metallic properties. Therefore, metallic fillers of different shape and size have been used to enhance the thermal conductivity in polymer-composites. However, there has been search of best geometrical fillers which can maximize the thermal conductivity effectively with …
