A new type of layered oxy-acid salt of bismuth oxynitrate was synthesized by a simple hydrothermal method. The obtained bismuth oxy-nitrates consist of a Bi2O2(2+) layered module inserted into the interlamellar anion modules of NO3(-) and OH(-). Varying amounts of NO3(-) and OH(-) complexes on the surface of the bismuth oxynitrate were also obtained by adjusting the precursor pH before hydrothe...

background and objectives: pseudomonas aeruginosa is an opportunistic pathogen that can produce biofilm. biofilm is a complex, three dimensional structure in which microorganisms are attached to a surface and embedded in a matrix made of extracellular polymers. due to high resistance to antimicrobial agents, biofilms create difficulties in various situations in healthcare. in this study, antibi...

INTRODUCTION Bismuth subgallate is a salt derived from heavy metal. The aim of this study was to evaluate the effect of this salt on some phases of healing. OBJECTIVES To assess the effect of subgallate on mucosa and to evaluate the association between the use of bismuth subgallate and neogenesis of vessels in oral mucosal wounds. METHODS This was a prospective and experimental study. This ...

In this work, studies of morphological and structural characteristics of BiOCl/AgX heterostructures (X = Cl, I) synthesized using ion-exchange reactions have been conducted. It was found that silver chloride (AgCl) crystals precipitating on the surface of bismuth oxychloride crystals show orientation ordering with the (001)BiOCl||(100)AgCl crystallographic relationship. Using two synthesis rout...

In recent years, there has been a significant increase in interest ternary and quaternary compounds with the participation of rare earth elements (REE), as well copper, antimony, bismuth, which have wider range physical properties. Due to their valuable properties, they become promising targets research for modern materials science. Therefore, purpose this work is study properties synthetic ana...

Abstract The processing of sodium (Na) and bismuth (Bi)-based piezoelectric compounds are always a concern due to their volatilization at high temperatures (> 1000 °C) the hygroscopic nature precursors. effect drying impurities in precursors on 0.94(Bi 0.5 Na TiO 3 )–0.06BaTiO (BNTBT) ceramics was investigated. A substantial difference weight fraction polar ( R3c ) weak-polar P4bm phase room...

Recent studies have demonstrated that bismuth oxyhalides with a 2D structure inhibit the recombination of electron–hole pairs. Further, perovskite-like strontium bismuth-based compounds special layered Sillen X1 shown potential for use as effective visible-light photocatalysts. Here, series oxyhalide composites were prepared under different calcination conditions. The sample compositions contro...

The use of combinations of drugs in the treatment of syphilis was reviewed by Willcox (1954). He appraised trends in the use of pencillin alone and in combination with arsenic, bismuth, and mercury compounds. Of the participating clinics in the study, 65-3 per cent. used penicillin alone and 28-9 per cent. used penicillin in combination with other drugs, while the remaining 5-8 per cent. used a...
