A simple methodology is developed to directly synthesize three-dimensional (3D) electrochemically supercapacitive arrays, consisting of multiwalled carbon nanotubes conformally covered by nanocrystalline vanadium nitride, firmly anchored to glassy carbon or Inconel electrodes. These nanostructures demonstrate a respectable specific capacitance of 289 F g–1, which is achieved in 1 …
Sep 01, 2016· In summary, we have developed a novel and controllable in-situ technique based on the self-assembly and support of ionic amphiphilic triblock copolymer to fabricate vanadium nitride nanoparticles on porous carbon nanospheres, which was further used as anode materials for supercapacitor application.
The goal of replacing combustion engines or reducing their use presents a daunting problem for society. Current lithium-ion technologies provide a stepping stone for this dramatic but inevitable change. However, the theoretical gravimetric capacity (∼300 mA h g–1) is too low to overcome the problems of limited range in electric vehicles, and their cost is too high to sustain the commercial .
Hybrid materials of vanadium nitride and porous carbon nanoparticles (VN/PCNPs) were fabricated by a facile pyrolysis process of vanadium pentoxide (V2O5) xerogel and melamine at relatively low temperature of 800 °C for supercapacitor application.
Mesocrystal nanosheets of vanidium nitride (VN) are developed via a confined-growth route from thermal-stable layered vanadium bronze for the first time. VN mesocrystal nanosheets with facet-tunable building blocks bring synergic advantages of unprecedentedly high electrical conductivity and unique pseudocapacitive reactivity, giving a
Pulsed laser deposition (PLD) with a YAG:Nd laser was used to prepare vanadium nitride thin film. Different deposition conditions of different temperatures, substrates and gas pressure were explored.
Highlights: • Hierarchical VN nanostructures were prepared on graphite foam. • Electrolyte preference of VN supercapacitor electrodes was explored. • VN showed better capacitive property in organic and alkaline electrolytes than LiCl. - Abstract: Vanadium nitride hierarchical nanostructures .

In this research, rheological and tribological performance of additive V 2 O 5 nanoparticles in a light mineral oil has been investigated. For rheological performance, the addition of 0.2 wt. % V 2 O 5 could reduce the viscosity of the base oil for 6%. Considering the overall friction reduction in boundary, mixed, and hydrodynamic lubrication regimes, that with 0.1 wt. % V 2 O 5 exhibited the .
