[Mg.sub.1.8][La.sub.0.2]Ni--xNi nanocomposites for electrochemical hydrogen storage
Article Abstract:
The [Mg.sub.1.8][La.sub.0.2]Ni--xNi (x = 1, 2, and 3) nanocomposites are synthesized by high-energy ball-milling and their morphology and microstructures are evaluated. The results have shown that the formation of the amorphous and nanocrystalline structure with the Ni, which is introduced after the ball-milling, plays a vital role in the significant improvement of the electrochemical hydrogen storage performance.

Electrostatic versus no electrostatic effects in DNA sequence discrimination by divalent ions [Mg.sup.2-] and [Mn.sup.2+]
Article Abstract:
An investigation of the selectivity of [Mg.sup.2+] and [Mn.sup.2+] ions toward nucleic acid indicated that the reduced selectivity of [Mn.sup.2+] toward nucleobases is due to larger tolerance for distortions and larger polarizability that is coupled to less favorable solvation of the complexes.
