Anodic aluminum oxide (AAO) membranes with highly ordered nanopores serve as ideal templates for the formation of various nanostructured materials. The procedure of the template preparation is based on a two-step self-organized anodization of aluminu

Nickel–titanium- group 5A metal (V, Nb, Ta, Zr) alloys are known as promising hydrogen-selective membrane materials. They can potentially be used in membrane reactors, which can produce high-purity H2 and CO2 streams from coal-derived syngas at ele

FeTi has one of the highest hydrogen volume storage capacity and its hydride - very favourable absorption/desorption conditions and a high reversibility. However, for applications its low hydrogen mass storage capacity (HMSC) has to be improved. The
