Production of nanoparticles has been attractive by biological based fabrication as an alternative to physical and chemical approaches due to exceeding need to develop safe, reliable, clean and eco-friendly methods for the preparation of nanoparticle for pharmaceutical and biomedical applications. In the present study, biogenic tellurium nanoparticles (TeNPs) were successfully prepared using pot...

Mohamed HF, El-meleigy MA, Salem MS Abstract— Tellurium-tolerant actinomycete was isolated from the soil sample collected from an Egyptian contaminated site in Hellwan City near to a cement factory. Isolate identification was done using morphological, physiological and biochemical characterization, chemical analysis of the cell wall, cultural characteristics using the recommended media of the i...

The crystal structure of the title compound, α-PbTeO(3) (PTO), has been reported previously by Mariolacos [Anz. Oesterr. Akad. Wiss. Math. Naturwiss. Kl. (1969), 106, 128-130], refined on powder data. The current determination at room temperature from data obtained from single crystals grown by the Czochralski method shows a significant improvement in the precision of the geometric parameters w...

Shewanella oneidensis MR-1 reduces selenite and tellurite preferentially under anaerobic conditions. The Se(0) and Te(0) deposits are located extracellularly and intracellularly, respectively. This difference in localization and the distinct effect of some inhibitors and electron acceptors on these reduction processes are taken as evidence of two independent pathways.

The upconversion luminescence properties of Yb3+/Tm3+-codoped oxyfluoride tellurite glasses under 980 nm excitation are investigated experimentally. The intense blue and relatively weak red emissions centered at 475 and 649 nm corresponding to the transitions G4 → H6 and 1

A novel and disposable microchip (K-kit) with SiO(2) nano-membranes was developed and used as a specimen kit for in situ imaging of living organisms in an aqueous condition using transmission electron microscopy (TEM) without equipment modification. This K-kit enabled the successful TEM observation of living Escherichia coli cells and the tellurite reduction process in Klebsiella pneumoniae. Th...
