A saturated aqueous solution of sodium perchlorate (SSPAS) was found to be electrochemically superior, because the potential window is remarkably wide to be approximately 3.2 V in terms of a cyclic voltammetry. Such a wide potential window has never been reported in any aqueous solutions, and this finding would be of historical significance for aqueous electrolyte to overcome its weak point tha...

We propose and analyze a novel approach to quantum information processing, in which multiple qubits can be encoded and manipulated using electronic and nuclear degrees of freedom associated with individual alkaline-earth-metal atoms trapped in an optical lattice. Specifically, we describe how the qubits within each register can be individually manipulated and measured with subwavelength optical...

zno nanostructures of different methods and sizes were grown in a controlled manner using a simple hydrothermal and sonochemical technique. controlling the content of concentration and temperature of the reaction mixture, spherical nanoparticles zno structures could be synthesized at temperatures 100-150 °c with excellent reproducibility in solvothermal and at different power and time in sonoch...

In recent years, investigations into atomic catalysts has accelerated significantly. Although different have been developed, the introduction of main group elements is rarely considered. this work, possibility introducing alkaline/alkaline earth metals (AAEM), post-transition metal (Post-TM), and metalloids to form stable graphdiyne-based dual (GDY-DAC) revealed. The not only act as a promising...

Recent interest in the application of density functional theory prompted us to test various functionals for the van der Waals interactions in the rare-gas dimers, the alkaline-earth metal dimers, zinc dimer, and zinc-rare-gas dimers. In the present study, we report such tests for 18 DFT functionals, including both some very recent functionals and some well-established older ones. We draw the fo...

The interactions of phenazino-crown ether ligands with alkali, alkaline earth and selected toxic species were investigated using density functional theory modelling by employing B3PW91/6-311G ++ (d, p) level of theory. The complex stability was analysed in terms of binding energies, perturbation energies, position of highest molecular orbital and energy gap values. In general, the complexes for...

A group of highly efficient Zn(II)-dependent RNA-cleaving deoxyribozymes has been obtained through in vitro selection. They share a common motif with the '8-17' deoxyribozyme isolated under different conditions, including different design of the random pool and metal ion cofactor. We found that this commonly selected motif can efficiently cleave both RNA and DNA/RNA chimeric substrates. It can ...

The existence of a series of triatomic molecules with the general formula MNM', where M is an alkaline metal (K, Rb, Cs), and M' is an alkaline earth metal (Ca, Sr, Ba), has been predicted by quantum chemical methods. Among these, the CsNBa molecule shows a feature not found before, the presence of a multiple bond between barium and nitrogen. As a consequence of this novel bonding situation, th...
