There is much about the action of bismuth within heterogeneous catalysis that still require a deeper understanding. We observed that, when Bi was added to AuPd bimetallic nanoparticles (NPs) supported on activated carbon, affected activity and significantly alters selectivity in two model liquid phase reactions, namely oxidation cinnamyl alcohol hydrogenation cinnamaldehyde. A combination trans...

Purpose: In the current study, we aimed to look into macroscopic and microscopic dose enhancement effect of metallic nanoparticles in interstitial brachytherapy gastric adenocarcinoma by Iodine-125 source using a nano-lattice model MCNPX (2.7) MCNP6.1 codes. Materials methods: Based on simulation containing radiation tumor tissue with cellular compartments loaded 7 mg/g spherical nanoparticles,...

bismuth salts and different antimicrobials including metonidazole & tetracyclines were used in the assessment of inhibition zone of helicobacter pylori cultures on solid media. antibiotics were used or in combined in order to find out their possible synergistic effects. it was showed that: only bismuth substrate and not then salts have antibacterial effects on helicobacter pylori and also on th...

The inherent radioresistance and inaccuracy of localization of tumors weaken the clinical implementation effectiveness of radiotherapy. To overcome these limitations, hyaluronic acid-functionalized bismuth oxide nanoparticles (HA-Bi2O3 NPs) were synthesized by one-pot hydrothermal method for target-specific computed tomography (CT) imaging and radiosensitization of tumor. After functionalizatio...

Introduction: In recent years, bismuth-based nanomaterials have been widely used in medical researches as imaging, drug delivery and x-ray radiosensitizing agents. Due to their anti-microbial effects against Helicobacter pylori (HP), bismuth colloidal compounds are used to treat various types of diseases such as chronic gastritis. Despite their advantages, bismuth-based compoun...

The reactions of bismuth(III) nitrate pentahydrate and bismuth(III) chloride with heterocyclic thiosemicarbazones and derivatives of dithiocarbazonic acid methylester were used to synthesize the respective bismuth(III) complexes, which could be divided into five groups D-H because of their stoichiometrical properties and their molecular structures. The molecular structure and the near coordinat...
