The high Faradic redox active material of Cu<sub>7</sub>S<sub>4</sub>-NWs coated on a carbon fiber fabric is directly used as binder-free electrode for performance flexible solid state supercapacitor.
Electronic and transport properties of Bi2O2Se under strain are calculated using Tran–Blaha modified Becke–Johnson (TB-mBJGGA) potential semiclassical Boltzmann theories. The electronic band gap decreases with tensile compressive in-plane strain. We predict that the n-type Seebeck coefficient can be increased strain, while p-type Further, power factor doping For Bi2O2Se, large thermoelectric figure merit (ZT ≈ 1.42) could obtained (2.3%) at 800 K. Moreover, a higher ZT 1.76 achieved along ZZ...
Tungstates are important photoluminescence (PL) materials owing to their unique luminescence center. However, radiative or nonradiative recombination affected by defects and electron-phone coupling have not been well understood. In this paper, we synthesized CdWO4 nanorods studied its temperature-dependent PL spectrum from 20 300 K. Theoretical calculations demonstrate that Cd vacancy (VCd) O vacancies (VO0, VO1+, VO2+) induce extra levels in the band gap, which VCd, VO0, VO1+ mainly...
Ceria (CeO2) nanocubes were synthesized by a hydrothermal method and weak ferromagnetism was observed in room temperature. After ultraviolet irradiation, the saturation magnetization significantly enhanced from ~3.18 × 10-3 to ~1.89 10-2 emu g-1. This is due increase of oxygen vacancies CeO2 structure which confirmed X-ray photoelectron spectra. The first-principle calculation with Vienna ab-initio simulation package used illustrate mechanism after calculating density states (DOSs) partial...
Under the background of energy crisis, hydrogen owns advantage high combustion and shows considerable environment friendliness; however, to fully utilize this novel resource, major hurdle lies in its delivery storage. The development in-depth yet systematical methodology for two-dimensional (2D) storage media evaluation still remains be challenging computational scientists. In study, we tried our proposed protocol on a 2D material, g-C 3 N 5 , performance was characterized; with addition Li...
Single-crystalline wolframite-type monoclinic structure cobalt tungstate (CoWO${}_{4}$) nanowires were obtained by a solvothermal method at 180 \ifmmode^\circ\else\textdegree\fi{}C for 24 h with width of 20 nm and length 200 to 400 nm. Besides the strong blue-green light emission 10--250 K, we found much stronger broader near-infrared ranging from 700--1000 about 300 K under excitation wavelength 325 The dependence intensity on temperature are discussed introducing effect Co vacancies. This...
A Ni-based alloy was heat treated by changing the temperature and ambient atmosphere of treatment. Morphology, crystal structure, physical performance were characterized via SEM, XRD, TEM, PPMS. Results show that due to treatment process, grain growth removal impurities defects are promoted. Both orientation stress caused rolling reduced. The permeability saturation magnetization improved. hysteresis loss coercivity decreased. Higher leads increased improvement magnetization. Heat in...
