Abstract:
Quaternary strontium copper(I) lanthanoid(III) selenides are formed by the oxidation of elemental strontium, copper and the corresponding lanthanoid with selenium. Orange to red needle-shaped single crystals of SrCuPrSe3 and SrCuCeSe3 have been synthesized by heating mixtures of Sr, Cu, Pr / Ce and Se with CsI as a flux in evacuated silica tubes to 800°C for 7 d. Both compounds crystallize orthorhombically in space group Pnma with four formula units per unit cell, but with unlike lattice constants (a = 1097.32(6), b = 416.51(2), c = 1349.64(8) pm for SrCuPrSe3 and a = 846.13(5), b = 421.69(2),

Abstract:
X-ray diffuse scattering of SrTiO3has been measured at two photon energies, the first just below the absorption edge and the second far from theKabsorption edge of strontium, in order to vary the atomic scattering factor of the strontium cations. It is shown that two different models of cation displacement comply with the single-energy diffuse scattering patterns, because single-energy diffuse scattering provides only ambiguous information on the directions of displacement of the Sr2+and Ti4+cations. However, the application of multi-energy anomalous diffuse scattering determines unambiguously

Asexual yeast flocculation was studied using strong flocculents of Saccharomyces cerevisiae. The inhibitory effect of cations on flocculation is considered to be caused by competition between those cations and Ca2+ at the binding site of the Ca2+-requiring protein that is involved in flocculation. Inhibition of flocculation by various cations occurred in the following order: La3+, Sr2+, Ba2+, Mn2+, Al3+, and Na+. Cations such as Mg2+, Co2+, and K+ promoted flocculation. This promoting effect may be based on the reduction of electrostatic repulsive force between cells caused by binding of these

Abstract:
Abstract Barite is a common mineral scale in oilfields that presents significant flow assurance challenges due to its deposition on pipe surfaces. Various models have been developed to predict barite crystallization and inhibition, but high concentrations of divalent cations such as Ca2+ and Sr2+ in oilfield brines can significantly alter crystallization kinetics. This study aims to evaluate the effects of Ca2+ and Sr2+on barite crystallization and inhibition kinetics and improve the accuracy of minimum inhibitor concentration (MIC) predictions under varying conditions.

Abstract:
To further document the involvement of external Ca2+ in the platelet induced-activation process, we have studied the arachidonate (AA) metabolism of intact washed rat platelets in the presence of different concentrations of Ca2+, Sr2+ or Ba2+. The thrombin-induced mobilization of [3H]- or [14C]-AA preincorporated into platelet phospholipids was followed as well as the subsequent formation of labeled cyclooxygenase and lipoxygenase products (CLP). Results indicate that upon thrombin (&lt;0.1 U/ml) stimulation, AA release and CLP formation are reduced by 50 to 90% only by omission of Ca2+ as com

Abstract:
Radioactive waste treatment is planned in LWTF (Low-level radioactive Waste Treatment Facility, JAEA) for LLW generated from the Tokai-reprocessing facility. The target LLW consists of highly concentrated sodium nitrate (5 M NaNO3) containing low-level 90Sr. In this study, selective adsorption properties of Sr2+ for highly functional A type zeolites (A51-JHP, A51-J (Union Showa) and A-4, X type zeolite (F-9) and Titanic acid-PAN (polyacrylamide) were clarified by batch and column adsorption methods. The irradiation stabilities of these adsorbents were also evaluated. The distribution propertie

Abstract:
Development of advanced technologies for electronic applications, particularly aiming to increase energy efficiency and sustainability, are increasing in demand for regular usage. A majority of this development involves improvement of material's properties. Researcher has been continuously studied and developed new electronic material. Ferroelectric ceramic is one of many materials that is of interest, for example, lead-based (e.g. Pb(Mg₁/₃Nb₂/₃)O₃: PMN) and lead-free (e.g. Ba(Zr,Ti)O₃: BZT) materials. It is, however, known that the RoHS (Restriction of Hazardous Substances Directive) listed L
