We report on the optical spectroscopy of monolithic fiber preform prepared from nanoporous bismuth-doped silica glass. The experiments reveal the existence of at least two different types of active centers and clearly demonstrate that the presence in the glass matrix of other dopant is not necessary to obtain the near-IR photoluminescence connected to Bismuth.

Reports of molecular and cellular imaging using computed tomography (CT) are rapidly increasing. Many of these reports use gold nanoparticles. Bismuth has similar CT contrast properties to gold while being approximately 1000-fold less expensive. Herein we report the design, fabrication, characterization, and CT and fluorescence imaging properties of a novel, dual modality, fluorescent, polymer ...

Previous studies have shown bismuth subsalicylate (BSS) has antimicrobial properties, but few studies have addressed the mechanism of action. Furthermore, following BSS ingestion other bismuth salts form throughout the gastrointestinal tract including bismuth oxychloride (BiOCl) that also act upon enteric pathogens. To further understand the antimicrobial activity of bismuth in infectious diarr...

By means of first principles calculations, we compute the effective electron-phonon coupling constant G(0) governing the electron cooling in photoexcited bismuth. G(0) strongly increases as a function of electron temperature, which can be traced back to the semimetallic nature of bismuth. We also use a thermodynamical model to compute the time evolution of both electron and lattice temperatures...

BiOI nanosheets are easily synthesized by direct thermal treatment of commercial BiI3 powder, serving as a novel anode material for lithium-ion batteries. A high volumetric capacity of ∼5678 mA h cm(-3) was achieved. This work demonstrates that the BiOI nanosheets hold great promise as high-energy anode material for lithium-ion batteries.

Abstract: Bismuth(III) compounds (BiX3, X = Cl, Br, NO3 and OTf etc.) are moistureand air-tolerant Lewis acids, which have been widely applied as green catalyst in diverse organic synthesis in the past few years. This review illustrates significant advances in this field over recent five years, and mainly focuses on the bismuth-catalyzed formation of carbon-carbon, carbon-nitrogen, carbon-sulfu...

Topological insulators are a relatively new class of materials, which are insulating in the bulk and conductive on the surface. Surface conductance measurements of topological insulators are often obscured by impurities in the bulk. Nanowires made of a topologically insulating material provide a solution to this problem with their large surface-area-to-volume ratio. I examine the growth procedu...

Octamethylcyclotetrasiloxane (OMCTS), a common constituent of household products, triggers the transformation of bismuth to the volatile toxic derivative trimethylbismuth by Methanosarcina barkeri, which is a representative member of the sewage sludge microflora. Comparative studies with the ionophores monensin and lasalocid, which induce effects similar to those observed for OMCTS, indicated t...
