XRD, FTIR and ultrasonic investigations of cadmium lead bismuthate glasses.

Cadmium lead bismuthate glasses in the system xCdO-(1-x)[0.5PbO + 0.5BiO](40 mol% ≤ x ≤ 90 mol%) were successfully prepared by melt-quenching method.

New solid-state membrane and coated wire potentiometric sensors for the determination of Zn(II) ions based on nanoparticles.

The first, novel solid-state membrane sensor for Zn(II) determination is developed based on ZnS nanoparticles. ZnS nanoparticles are synthesized by chemical co-precipitation and investigated via X-ray diffraction, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and impedance study. X-ray diffraction shows that the prepared ZnS nanoparticles have an average domain size of 5.
