Potassium tellurite (K2TeO3) was found to be a potent antisickling agent that inhibited red cell sickling at concentrations less than 10 mumol/L. The inhibitory effect depended on the incubation time, with the effect increasing with longer incubation periods. Because tellurite causes swelling of red cells, and because the antisickling effect of tellurite correlated with the degree of red cell s...

Microresonator-based lasers in the two-micron range are interesting for extensive applications. Tm3+ ions provide high gain; therefore, they promising laser generation various matrices. We developed a simple theoretical model to describe Tm-doped glass microlasers generating 1.9–2 μm with in-band pump at 1.55 μm. Using this model, we calculated threshold powers, wavelengths and slope efficienci...

Several transporters suspected to be involved in tellurite uptake in Escherichia coli were analyzed. Results showed that the PitA phosphate transporter was related to tellurite uptake. Escherichia coli ΔpitA was approximately four-fold more tolerant to tellurite, and cell viability remained almost unchanged during prolonged exposure to the toxicant as compared with wild type or ΔpitB cells. Not...

We report the symmetry of mechanical and gamma-ray attenuation properties for some tellurite glasses through elastic moduli, mechanical, transmission as a function varied WO3 amount in glass configuration. Four samples, along with different molar compositions well WO3/GdF3 substitution ratios, are investigated. Transmission using several essential parameters, such coefficients, half-value layer...

Seven species of obligately aerobic photosynthetic bacteria of the genera Erythromicrobium, Erythrobacter, and Roseococcus demonstrated high-level resistance to tellurite and accumulation of metallic tellurium crystals. High-level resistance without tellurite reduction was observed for Roseococcus thiosulfatophilus and Erythromicrobium ezovicum grown with certain organic carbon sources, implyin...

Two methods were proposed and implemented for the fabrication of channel waveguides in an Er-doped Tellurite glass. In first method, fabricated by implanting 1.5 MeV 3.5 energy N+ ions through a special silicon mask to glass sample at various fluences. Those implanted fluence 1.0 × 1016 ions/cm2 operated up 980 nm, showed green upconversion Erbium ions. second directly written Er3+: TeO2W2O3 us...
