We report the fabrication of thermoelectric bismuth teUuride nanowires using the template synthesis method. A simple electrodeposition procedure was used to produce the nanowires within the pores of an alumina filtration membrane. The resulting bismuth telluride/alumina composite membranes constitute an array of thermoelectric nanowires surrounded by a thermally and electrically insulating matr...

This review covers uses of bismuth catalysts since 2005 with a special emphasis on the emerging applications of such catalysts. Low toxicity, low catalytic loading, synergistic effects with other catalysts, and some hydrocompatibility properties confer to bismuth salts major advantages. The expanding activity in the field clearly highlights the growing potential of bismuth catalysts. The articl...

Consumption and production of bismuth compounds are increasing, however, little information on the toxic effects and effective methods in removal of bismuth compounds are available. Although bismuth intoxication is currently rare, a careful evaluation should be carried out for possible exposure. We reported a16-year-old female who developed acute kidney failure, tonsillar ulceration and posteri...

Bismuth compounds have been used since the 18th century to treat gastrointestinal ailments in man. Colloidal bismuth subcitrate (De-Nol) is currently used in combination with antibiotics to reduce enteric Helicobacter pylori colonization as a treatment of stomach ulcers. We investigated whether bismuth citrate or its parent compound, colloidal bismuth subcitrate, would reduce colonization of th...

SiO 2 /Bi WO 6 photocatalyst with Si/Bi/W=1:2:1 molar ratio was obtained by the sol-gel method from bismuth nitrate, sodium tungstate and biogenic silica rice husk biomass followed calcination. Bi used as a control sample. FT-IR, SEM, XRD, EDXRF, UV-Vis methods were to systematically characterize as-obtained materials. Photodegradation of Indigo Carmine in exposure UV, sunlight xenon light stud...

In an interesting Turkish retrospective study, conducted between 2012 and 2015, involving 1510 adults, Kekilli et al.[1] tested triple therapy (lansoprazole 30 mg b.i.d., clarithromycin 500 mg b.i.d., and amoxicillin 1 g b.i.d.), bismuth group C (lansoprazole, clarithromycin, amoxicillin, and bismuth subsalicylate 524 mg b.i.d.), and bismuth group M (lansoprazole, amoxicillin, metronidazole 500...

BiOCl microflowers were synthesized using bismuth nitrate pentahydrate and sodium chloride by microwave (MW) assisted synthesis method for 23 minutes at 180 W. Scanning electron microscopy (SEM) studies revealed a unique morphology of flower-like assemblies comprised of nanosheets. The X-ray diffraction (XRD) pattern showed that a highly pure and crystalline phase has been obtained. The energy ...

For the last three centuries, Bismuth compounds have been of traditional importance for the treatment of infectious diseases, syphilis, amoebiasis, dyspepsia and diarrhea 1. Despite its old history, intensive research and investigation on the mechanism of action and its clinical efficacy has begun in recent years.Trivalent bismuth preparations such as bismuth subsalicylate (BSS) and colloidal b...

A novel optical sensor has been proposed for sensitive determination of bismuth ion basedon immobilization of 4-(4-nitrophenylazo)-1-naphthol on a triacetylcellulose membrane.Chemical binding of bismuth ions in solution with a 4-(4-nitrophenylazo)-1-naphtholimmobilized on the triacetylcelluse surface could be monitored spectrophotometrically. Theoptode shows excellent response over wide concent...
