A novel alloy LaTi 2 Ni 5 Al 4 is investigated in this work. This quaternary composite belongs to the new generation of AB 3 intermetallics elaborated using the mechano-milling method. Several analytical techniques are operated in order to verify and confirm the crystallographic patterns following the growth progression of this nanoalloy. Starting from elemental metals, the authors show that they have basically LaTi 2 Ni 5 Al 4 major pattern corresponding to the symmetry crystal system (Trigonal R-3 m SG: 166). Structure refinement simulation demonstrates that performing this preparation with a laboratory grinding and milling benchtop, they obtain a maximum proportion of AB 3 intermetallic alloy after 20 h of metallurgy work processing. The proposition of useful stabilised solid-hydrogen encapsulation is highlighted and tested using a specific lithium-hydride cell.

The synthesis, crystal structure and physico-chemical characterization are presented for the piperazinium bis iodate dihydrate. An X-ray investigation has shown that this compound crystallizes in a non-centrosymmetric monoclinic system, space group Pc with the lattice parameters: a = 8.969 (2)
