In recent years, green synthesis of nanoparticles has attracted a great attention because of medicine and biological applications. In this work, bismuth oxide nanoparticles (Bi2O3 NP) was prepared via green synthesis using mentha pulegium aqueous extract after 24 h at 90°C. The product was characterized by ultraviolet-visible (UV-VIS) spectrophotometer, Fourier transform infrared (FTIR), X-ray ...

Bismuth oxide directly grown on nickel foam (p-Bi2O3/Ni) was prepared by a facile polymer-assisted solution approach and was used directly as a lithium-ion battery anode for the first time. The Bi2O3 particles were covered with thin carbon layers, forming network-like sheets on the surface of the Ni foam. The binder-free p-Bi2O3/Ni shows superior electrochemical properties with a capacity of 66...

We prepared an α-Bi2O3/BiOBr core-shell heterojunction via a facile in situ chemical transformation method. Ultrathin BiOBr nanosheets were observed and these were found to be evenly distributed on the surface of α-Bi2O3/BiOBr by SEM and TEM. The results revealed that the prepared α-Bi2O3/BiOBr photocatalysts were porous, and their specific surface areas were found to be raised on comparing wit...

In this work, a facile method to prepare Bi2O3 decorated activated carbon (Bi2O3@AC) composites with high pseudocapacitive properties was presented. The inorganic–organic synthesized using commercial and active different weight ratio. were assessed spectroscopic, microscopic, diffractive techniques. Our assessments confirmed that carbons successfully doped nanoparticles dopant rates. electroche...

This study provides the first proof of the novel application of bismuth oxide as a radiosensitiser. It was shown that on the highly radioresistant 9L gliosarcoma cell line, bismuth oxide nanoparticles sensitise to both kilovoltage (kVp) or megavoltage (MV) X-rays radiation. 9L cells were exposed to a concentration of 50μg.mL-1 of nanoparticle before irradiation at 125kVp and 10MV. Sensitisation...

Based on a facile vapor-phase transport method without any catalyst and template, one-dimensional single-crystalline bismuth oxide (Bi2O3) micro/nanoribbons were fabricated on silicon substrates in large quantities and morphology-controlled fabrication of Bi2O3 was achieved from a single precursor. The widths of Bi2O3 ribbons varied from 0.2 to 20 microm depending on the deposition temperatures...

The green synthesis method synthesized the bismuth oxide and lead-doped nanoparticles using Ferula Asafoetida leaves extract. showed greater degradation efficiency than undoped oxide. This was due to decreases in band gap energy between valence conduction of metal reduced chances electron-hole pair recombination with catalyst. were characterized by TGA, SEM, FT-IR, EDX, XRD, UV- visible Spectro...

OBJECTIVES To investigate chemo-mechanical effects of incorporating alkaline bioactive glass nanoparticles into a light-curable dental resin matrix. METHODS An unfilled Bis-GMA/TEGDMA material was infiltrated with up to 20 wt% of ultrafine SiO2-Na2O-CaO-P2O5-Bi2O3 particles. The unfilled and filled resins were investigated regarding their viscosity before setting and compared to commercially ...
