Abstract The structure family of the rare‐earth calcium oxoborates O[BO 3 ] (RCOB) has been investigated mainly with regard to their optical characteristics. Due monoclinic‐domatic they exhibit pyro‐ and piezoelectric properties, which is not dependent on numerous possible substitutions cation site R . cations are known show partial disorder earth alkaline positions X Z To study whether a stabi...

Coordination compounds with mixed ligands were synthesized 2A group (Mg2+, Ca2+, Ba2+, Sr2+) alkaline earth metal cations of coumarilic acid and nicotinamide ligands. Afterward, the structural properties these new molecules investigated by melting point, elemental analysis, infrared spectroscopy, thermal analysis (TGA / DTA) curves, powder X-ray diffraction (P-XRD) spectroscopy. It has been sug...

A proton NMR method for the determination of the solvation numbers of alkaline earth cations with dimethylsulfoxide (DMSO) in nitromethane as diluent is described. The method is based on the monitoring of the resonance frequency of DMSO protons as a function of DMSO to metal ion mole ratio while keeping the metal ion concentration constant. The average solvation number of cations at any...

A number of new binuclear complexes have been synthesised by interaction of stable Ni(II) and Cu(II) metal chelates of p-Methylisonitroacetosophenone with Alkaline earth metal salts having general formula[Ma(p-MeINAP)2MbL2 or MbX2]where Ma=Ni(II) or Cu(II),p-MeINAP = deprotonated pMethyiIsonitrosoacetophenone, Mb= Ca ++ or Mg ++ ,L = deprotonated ortho amino benzoic acid and 8hydroxyquinoline X...

The heat capacities of MgO, CaO, SrO and BaO, reported in part I have been analysed in terms of the frequency spectrum of the lattice with the assumption that the effect of anharmonicity of the lattice may be neglected for T (@D / 3 ) . Following the usual procedure the n-th moments of the frequency spectrum with n = — 3, —2, — 1, 0, 1 to 6 were calculated from the experimental data. From the l...

We present a complete scheme for quantum information processing using the unique features of alkaline-earth-metal atoms. We show how two completely independent lattices can be formed for the 1S0 and 3P0 states, with one used as a storage lattice for qubits encoded on the nuclear spin, and the other as a transport lattice to move qubits and perform gate operations. We discuss how the 3P2 level c...
