Abstract (sommario):

Mineral trioxide aggregate (MTA) is an ideal yet costly endodontic sealer material. Tricalcium silicate-white Portland cement (TS-WPC) seems to have similar characteristics to those of MTA. This work aims to characterize a modified TS-WPC and evaluate its antibacterial properties as a potential endodontic sealer material. The modified TS-WPC was synthesized from a 4:1 mixture of sterilized Indocement TS-WPC and bismuth trioxide using a simple solution method with 99.9% isopropanol. The mixture was stirred until it was homogenous, centrifuged, and dried. The material was then characterized usin

Abstract (sommario):

Herein, a novel superhydrophobic functionalized nano-Bi2O3 coating is designed and fabricated using electrophoretic assembly deposition (EAD) in the optimal suspension of polyethylene glycol, ethanol, acetylacetone, and surface functionalization. The small size (70 nm, nano-scale) of Bi2O3 particles and uniform distribution make the target film possessing a promising structure for realizing hydrophobic functionalization. Moreover, the hydrophobicity and stability results indicate that the product has a high-water contact angle (CA) of ca. 167° and is kept almost stable after 180 days exposure

Abstract (sommario):

Intensely yellow β -bismuth trioxide in the form of about 41 nm large crystallites has been prepared by thermal decomposition of (BiO)2CO3 at 400 ◦C. From the band gap energy of 2.3 eV obtained under the assumption of an indirect band-to-band transition and the quasi-Fermi level of −0.28±0.02 V (vs. NHE) a valence band edge position of 2.02 V is calculated. This semiconducting oxide assists a Vis light (λ ≥455 nm) aerial mineralization of the aqueous model pollutants phenol and 4-chlorophenol exhibiting maximum rates at a bismuth oxide concentration of 2.0 g L−1. In the absence of oxygen no de

Abstract (sommario):

Silver-zinc slag, containing a lot of Bi, Ag, Cu, Zn, Pb and a little Au, has high comprehensive utilization value. This paper describes a preparation method of high-purity nanometer bismuth trioxide (Bi2O3) from silver-zinc slag by hydrometallurgical method. The results showed that Bi could be effectively leached out from silver-zinc slag using sodium chlorate, hydrochloric acid and sodium chloride as leaching agents, and the leaching rate of Bi was up to 99.03% under the optimum conditions. The contents of Pb2+ and Ag+ in BiCl3 solution could be reduced to about 1mg/L by using silver-zinc sl

Abstract (sommario):

[Truncated abstract] New, double-doped, Bi2O3-based materials in the Bi2O3 Ln2O3 PbO (Ln = La, Nd, Er and Yb) and Bi2O3 WO3 PbO systems were prepared using solid-state reactions. For the Bi2O3 Er2O3 PbO and Bi2O3 Yb2O3 PbO systems, the air-quenchable compositional domain of the fcc fluorite-type phase was partially established. Temperature dependent conductivity measurements were performed on these quenched-in fluorite-type materials using AC impedance spectroscopy. Conductivity at 750[degrees Celsius] generally increased with increasing Pb2+/Ln3+ and decreasing (Ln3++Pb2+)/Bi3+ ratios

A radiopacidade e a resposta tecidual do cimento Portland (CP) acrescido de óxido de bismuto (OB) nas concentrações de 0, 15, 20, 30 e 50%, determinadas em peso, foram avaliadas. Para a análise da radiopacidade, foi seguida a norma ISO 6876/2001. A densidade radiográfica foi mensurada em milímetros de alumínio (mmAl) e a análise estatística realizada utilizando-se os testes de ANOVA e Tukey-Kramer (p<0,05). Para a análise da resposta tecidual foram selecionados 81 ratos albinos e cada um recebeu como implante, na região dorsal, dois tubos de polietileno preenchidos com os cimentos experimenta
