The phase stability diagrams for the decomposition of magnesium alanate [Mg(AlH4)2] nanoparticles were constructed as a function of particle size and temperature to better understand nanostructuring of the complex hydrides for hydrogen storage. Relatively smaller nanoparticles of Mg(AlH4)2, MgH2, Al, and Mg ranging from 1 to 2 nm were directly calculated by using density functional theory (DFT)...

Nanosized titanium particles have attracted extensive research interest because of their diverse applications in, for instance, catalysis, energy conversion, and biomedical engineering. Of these, titanium colloids have been used as effective catalysts for the hydrogenation of titanium and zirconium sponses and as a powerful activator for heterogeneous hydrogenation catalysts. Titanium nanoparti...
