Clarification of the microscopic events that occur during oxidation is of great importance for understanding and consequently controlling the oxidation process. In this study the oxidation product formed on T91 ferritic/martensitic steel in oxygen saturated liquid lead-bismuth eutectic (LBE) at 823 K was characterized at the nanoscale using focused-ion beam and transmission electron microscope....

Multiresistance among microorganisms to common antimicrobials has become one of the most significant concerns in modern medicine. Nanomaterials are a new alternative to successfully treat the multiresistant microorganisms. Nanostructured materials are used in many fields, including biological sciences and medicine. Recently, it was demonstrated that the bactericidal activity of zero-valent bism...

A new method is presented for interpreting the Raman spectra of bismuth oxides. The method relies on empirical relations between bismuth-oxygen (Bi-0) bond lengths, bond strengths, and Raman stretching frequencies. A least-squares exponential fit of crystallographically determined Bi-0 bond lengths and Raman stretching frequencies is presented along with a relation between Bi-0 bond strengths, ...

Rhodamine B (RhB) is a water-soluble fluorescent dye that is often used to determine flux and flow direction in biotechnological and environmental applications. In the current research, RhB in soluble (termed free) and virus-bound (termed nano-bound) forms was used as an efficiency indicator for three environmental processes. The degradation of free and nano-bound RhB by (i) direct UV photolysi...

Nano -and microcrystalline bismuth metal powders consisting of spherical particles with a size 150-250 nm were obtained by reducing formates in an ethylene glycol medium. The phase composition and morphology the reaction products studied X-ray thermal analysis, differential scanning calorimetry, transmission electron microscopy. Using Uv-vis, it was shown that bismuth-ethylene complex is formed...

Bismuth ferrite (BiFeO3) nanocomposites were synthesized using a novel nano-agitator bead milling method followed by calcination. oxide and iron nanoparticles mixed in stoichiometric ratio milled for 3 h calcined at 650 °C air. X-ray diffraction with Rietveld refinement, scanning electron microscopy, transmission microscopy techniques used to elucidate the structure of BiFeO3. The particle diam...

Significantly enhanced superbroadband near infrared emission has been realized in bismuth/aluminum doped high-silica zeolite derived nanoparticles. The emission intensity can be easily tailored by the introduction of aluminum. The luminescence lifetime can reach up to 695 micros. The results reveal that the existence of charge imbalance environment caused by [AlOV(4/2)](-) units in host materia...

Bismuth sulfide nano-rods and nano-flowers were synthesized via a hydrothermal reaction at a relatively low temperature. Thioglycolic acid is used as sulfur source and capping agent simultaneously. Bi2S3 nanostructures were then added to acrylonitrile-butadiene-styrene (ABS) copolymer. The thermal stability behavior of ABS filled with bismuth sulfide nano-rods were investigated by thermogravime...

The effect of laser (532 nm line Verdi G) heating during the Raman measurements, on partial decomposition Bi12SiO20 single crystal, was addressed in this study. degree directly depends power density and duration treatment, which are registered by phonon spectra. After AFM measurements register additional small spherical islands surface. Analysis performed irradiated unirradiated samples showed ...
