A PVC-membrane ion-selective electrode was constructed for quantitative monitoring of gadolinium(III) ion based on 3-methyl-1H-1,2,4-triazole-5-ylhydrosufide (MTY) as an ion carrier. The electrode performance includes a Nernstian slope of 19.8 ± 0.4 mV per decade across a wide concentration range between 1.0 × 10 and 1.0 × 10 M and a detection limit of 7.3 × 10 M. The best performance was obtai...

Traditional nanostructured design of cerium oxide catalysts typically focuses on their shape, size, and elemental composition. We report a different approach to enhance the catalytic activity of cerium oxide nanostructures through engineering high density of oxygen vacancy defects in these catalysts without dopants. The defect engineering was accomplished by a low pressure thermal activation pr...

Treatment of Ce[N(SiHMe(2))(2)](3)(thf)(2) with the chlorinating agents PhICl(2), Ph(3)CCl or C(2)Cl(6) gave the homoleptic Ce(IV) silylamide Ce[N(SiHMe(2))(2)](4). When performed in the absence of donating (solvent) molecules, the trivalent cluster Ce(5)[N(SiHMe(2))(2)](8)Cl(7) was isolated.

Time-of-flight ~TOF! inelastic neutron-scattering spectra were measured on b-cerium ~double hcp! and g-cerium ~fcc! near the phase-transition temperature. Phonon densities of states ~DOS! and crystal-field levels were extracted from the TOF spectra. A softening of the phonon DOS occurs in the transition from bto g-cerium, accounting for an increase in vibrational entropy of DSvib 5(0.0960.05)kB...

Research into the incorporation of cerium a diverse range catalyst systems for wide spectrum process chemistries has expanded rapidly. This been evidenced since about 1980 in increasing number both scientific research journals and patent publications that address application as component multi-metal oxide system support material metal catalysts. review chronicles applied fundamental cerium-cont...

In the present work, the seedless, highly aligned and vertical ZnO nanorods in 3 dimensions (3D) were grown on the nickel foam substrate. The seedless grown ZnO nanorods were characterised by field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD) techniques. The characterised seedless ZnO nanorods in 3D on nicke...

Abstract— In the present paper, we have investigated the high-pressure structural phase transition of cerium monopnictide. The three-body potential model has been used to study the structural properties of this compound. Phase transition pressures are associated with a sudden collapse in volume. The phase transition pressures and associated volume collapses obtained from present potential model...

Optical dihydrogen phosphate-selective sensors that function on the basis of bulk optode principles and are based on two different uranyl salophene ionophores are reported here for the first time. The influence of the optode composition and measuring conditions such as sample pH on the optode response are characterized, along with sensor selectivity and long-term stability. Three plasticizers o...
