Influence of chemical potential on shape evolution of 2D-MoS flakes produced by chemical vapor deposition.

High-quality, ultrathin 2D-MoS layers with large area were grown on SiO/Si substrates by using atmospheric pressure chemical vapor deposition (APCVD) at elevated temperatures. The growth precursors (MoO and S) were placed separately inside the double-zone furnace to control the growth parameters individually for better flexibility in the growth process. In this study, it was found that the shape and edge structure of the evolved MoS flakes were significantly influenced by the chemical potential of the Mo and S precursor concentration.

Influence of chemical potential on shape evolution of 2D-MoSflakes produced by chemical vapor deposition.

High-quality, ultrathin 2D- MoS2 layers with large area were grown on SiO2/Si substrates by using chemical vapor deposition (CVD) at elevated temperatures. The growth precursors (MoO3 and S) were placed separately inside the double zone furnace to control the growth parameters individually for better flexibility in the growth process. In this study, it was found that the shape and edge structure of the evolved MoS2 flakes were significantly influenced by the chemical potential of the Mo and S precursor concentration.

VO₂ nanorods for efficient performance in thermal fluids and sensors.

VO2 (B) nanorods with average width ranging between 50-100 nm are synthesized via a hydrothermal method and the post hydrothermal treatment drying temperature is found to be influential in their overall phase and growth morphology evolution. The nanorods with unusually high optical bandgap for a VO2 material are effective in enhancing the thermal performance of ethylene glycol nanofluids over a wide temperature range as is indicated by the temperature dependent thermal conductivity measurements. Humidity and LPG sensors fabricated using the VO2 (B) nanorods bear testament to their efficient sensing performance, which can be partially attributed to the mesoporous nature of the nanorods.

Elastic and ultrasonic properties of single crystalline nickel nanowires.

In the present paper, we have theoretically calculated the non linear elastic constants of single crystalline Ni NWs at very broad temperature range 20-300K validating simple interaction potential model. The temperature dependent ultrasonic attenuation and other related properties are determined using their second and third order elastic constants (SOECs/TOECs). Where possible, the results are compared with experiments from literature.

NiO-based nanostructures with efficient optical and electrochemical properties for high-performance nanofluids.

NiO nanostructures were synthesized via a simple wet chemical solution method with varying calcination temperatures. The synthesized nanostructures were characterized by XRD, TG/DSC, FT-IR and high-resolution electron microscopy techniques. The nanostructures revealed dependence of particle size, stoichiometry, optical band gap and luminescence intensity on calcination temperatures.
