The methylammonium lead halides have become champion photoactive semiconductors for solar cell applications; however, issues still remain with respect to chemical instability and potential toxicity. Recently, the Cs2AgBiX6 (X = Cl, Br) double perovskite family has been synthesized and investigated as stable nontoxic replacements. We probe the chemical bonding, physical properties, and cation an...

Bismuth subsalicylate (BSS), the active ingredient of Pepto-Bismol, has been used for many years to treat various disorders of the gastrointestinal tract. Using mass spectrometry and the agar dilution method, we determined that insoluble BSS interacts with certain dietary components and organic substrates to produce water-soluble products with activity against Clostridium difficile.

BACKGROUND/AIMS Helicobacter pylori eradication rates with standard triple regimens are worsening, and alternative treatments are urgently needed in some populations. The present study aimed to compare the efficacy of bismuth-based quadruple and concomitant regimens. METHODS Consecutive Helicobacter pylori-positive patients with non-ulcer dyspepsia were randomized to receive one of two regime...

The optical absorption of bismuth nanowires in the energy (wavenumber) range of 600 4000cm-1 is studied. Optical reflection and transmission spectra reveal that bismuth nanowires have a large and intense absorption peak as well as several smaller absorption peaks which are not measured in bulk bismuth. The smaller absorption peaks fit reasonably well to theoretical models for intersubband absor...

The aim of this study was to determine the effect of colloidal bismuth subcitrate (De Nol) on symptoms and gastric histology in patients with non-ulcer dyspepsia. In a single centre trial, patients with food related upper abdominal pain not caused by ulcer disease were randomised to receive one tablet of colloidal bismuth subcitrate or matching placebo four times daily for eight weeks. Seventy ...

An enema that contained a complex of bismuth citrate and polyacrylate was compared with 5-aminosalicylic acid (5-ASA) enemas for treatment of distal ulcerative colitis. The multicentre trial involving 63 patients was randomised and double blind with enemas given over four weeks; clinical, sigmoidoscopic, and histological assessments were made. Improvements were seen in both treatment groups. Cl...

Abstract One of the global demands primary research objectives is to achieve human energy harvesting and self-powered wearable technologies. Bismuth chalcogenides are trending materials for thermoelectric generators Peltier coolers due their notable figure merit in low- room-temperature range. Systematic alloying bismuth leads a substantial change electrical thermal transport properties. The hi...

BACKGROUND Pseudomonas aeruginosa is an opportunistic pathogen that takes advantages of some weaknesses in the immune system to initiate an infection. Biofilms of P. aeruginosa can cause chronic opportunistic infections in immunocompromised and elderly patients. This bacterium is considered as a model organism to study antibiotic resistance as well as biofilm formation. In the biofilm structure...
