A combination of X-ray diffraction, analytical-electron microscopy, differential scanning calorimetry, impedance spectroscopy and electromotive force measurements (for oxide-ion transport number measurements, tion) are used to report on the influence a small amount continuous Bi2O3-rich phase along grain boundaries in sample composition x = 0.4 (BS0.4BT) high temperature dielectric solid soluti...

In the ZnO based varistor, the improvement of nonlinear coefficient (α) and prevention of evaporation of Bi2O3 during heat treatments can be achieved by the addition of MnO2 or Co3O4. In this conjunction, it is proper to see the effect of these additives at different low mol percentage and sintering conditions to nonlinear coefficient improvement of the varistor ceramics. In this paper, the inv...

Due to their enormous potential for large-scale energy storage, rechargeable potassium-ion batteries have been widely researched and developed. However, the drastic volume change of electrode materials induced by huge size potassium ions during cycling remains a challenge construction stable anodes. Herein, we propose novel weak acid etching strategy design fabricate robust yolk-shell spheres w...

Partially stabilized Y2O3–ZrO2 (Y-PSZ) is often used as a material in the field of oxygen sensors and batteries. However, presence tetragonal phase will seriously reduce conductivity Y-PSZ materials. As sintering aid, Bi2O3 can be to sinter materials with high ion at low temperatures. It first choice for doped system. A new microwave technique prepared Bi2O3–Y-PSZ powders. The effects doping am...

The hydrothermal method was used to synthesize carbon sphere, and the hard template synthesis prepared C-doped hollow TiO2 sphere (CHTS). Bismuth nitrate as bismuth source modify CHTS. composite material oxidized in air atmosphere at 450℃ obtain Bi2O3 modified spheres(BCHTS). morphology, elemental composition photocatalytic degradation efficiency of tetracyclines (TC) by BCHTS spheres were char...

The encapsulation of bismuth as BiOCl/Bi2O3 within ultra-short (ca. 50 nm) single-walled carbon nanocapsules (US-tubes) has been achieved. The Bi@US-tubes have been characterized by high-resolution transmission electron microscopy (HR-TEM), energy-dispersive X-ray spectroscopy (EDS), thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Bi@US-tubes ha...
