Abstract null null We introduce a generic, facile, and environment-friendly strategy to fabricate a flexible, low-cost, highly sensitive nanocomposite by incorporating electrospinning and hydrothermal process with self-powered sensor device that contributes towards a better and safer life. Our research work based on the novel composite α-Bi2Mo3O12/CoSO4 operating at room temperature shows fascinating ability to improve the long-term sensitivity and stability of gas sensors and a reduced cost of ...

The introduction of heterostructure is a new approach in gas sensing due to its easy and quick transport of charges. Herein, facile hydrothermal and solid-state techniques are employed to synthesize α-Fe2O3/Nb2O5 heterostructure. The morphology, microstructure, crystallinity, and surface composition of the synthesized heterostructure are investigated by SEM, TEM, XRD, XPS, and BET analyses. The mutual incorporation of α-Fe2O3 nanorods with Nb2O5 interconnected nanoparticles (INP) for the success...

Sulfuryl fluoride (SO2F2) is one of the ideal decomposition components of sulfur hexafluoride (SF6), which has been widely used as insulating and arc-quenching medium in gas-insulated switchgear (GIS) power equipment. To detect SF6 decomposition component at room temperature, use of SO2F2 still poses challenges. In this work, we have successfully prepared TiO2 nanofibers and Nickle sulfate (NiSO4 NPs) via facile electrospun and hydrothermal methods, followed by calcination process to improve sen...

The full-potential linearized augmented plane wave (FP-LAPW) process is applied for the investigation of structural, mechanical, electronic and including optical properties of cubic perovskites CdXF3 (X = Y, Bi). For the consideration of the exchange–correlation potential, the generalized gradient approximation and the modified Becke–Johnson are implemented. The structural properties, comprising equilibrium lattice constant, the bulk modulus and its pressure derivative are calculated and found t...

Herein, we report the study of half-Heusler ScTiX (X = Si, Ge, Pb, In, As, and Tl) compounds for the first time employing the scheme of density functional theory (DFT). The influence of on-site Coulomb interactions is taken into account, and simulations are conducted in generalized gradient approximation with the added Hubbard U term (GGA + U). All the compounds were observed to have a narrow band gap on the spin-down configuration. Though spinning the majority channel (spin-up), it is found to ...

Abstract An ultrasonic assisted spraying method was proposed to prepare TiN films in friendly conditions. The particle size effects of the nano-TiN suspensions upon the film structure, morphology, and optical properties were investigated. The results show that the larger particles (170 nm) form a porous structure, while the smaller ones (60 nm) form a dense structure. Both the films display good thermal stability under 700 °C vacuum annealing. The dense film shows a metal-like behavior of abnorm...

In this work, we report the spontaneous formation of NiO nanoparticles-decorated on smooth SnO2 nanofibers, which is an inexpensive and scalable method to yield high composite surface area via two steps facile synthesis process based on electrospinning and hydrothermal method. The layers of nanofibers, which containing the conducting electrolyte of proton, Nickel Oxide are deposited homogeneously over a large surface area from transparent solution of the electrolyte mixed and decorated on Tin di...

A novel composite based on α-Bi2Mo3O12/Co3O4 nanotube-decorated particles was successfully synthesized using a highly efficient and facile two step system using electrospinning and hydrothermal techniques. The small size Co3O4 nanoparticles were uniformly and hydrothermally developed on the electrospun α-Bi2Mo3O12 nanotubes. The pure α-Bi2Mo3O12 nanofibers and composite based on α-Bi2Mo3O12/Co3O4 were examined using X-ray powder diffraction (XRD), scanning electron microscopy (SEM), energy-dispe...
