Transformation of Metallic Ti to TiH Phase in the Ti/MgH Composite and Its Influence on the Hydrogen Storage Behavior of MgH.

The current work explores the in-situ formation of TiH additive in a Ti/MgH nanocomposite system. Mild mechanical milling leaves Ti chemically unchanged, while formation of stable TiH occurs upon strong mechanical milling. TiH further transforms to TiH upon recycling the powder (dehydrogenation and subsequent hydrogenation) and lowers the activation energy of MgH to 89.

Enhancing electrochemical performance by control of transport properties in buffer layers--solid oxide fuel/electrolyser cells.

The current work demonstrates how tailoring the transport properties of thin ceria-based buffer layers in solid oxide fuel or electrolyser cells can provide the necessary phase stability against chemical interaction at the electrolyte/electrode interface, while also providing radical improvements in the electrochemical performance of the oxygen electrode.
