Rare earth (RE) borohydrides have received considerable attention during the past ten years as possible hydrogen storage materials due to their relatively high gravimetric hydrogen density. This review illustrates the rich chemistry, structural diversity and thermal properties of borohydrides containing RE elements. In addition, it highlights the decomposition and rehydrogenation properties of ...
This study focuses on the amount and concentration of trace elements and REEs pattern in garnet crystals which experienced regional metamorphism in the central Iran micro-continent, including the areas of Deh-Salm, Zaman Abad, Mishdowan, and Tanbour. Generally, garnet crystals are isolated from mica schists of greenschist to amphibolite facies. Mineralogical composition of garnets shows almandi...
