A facile and fast approach for the synthesis of a nanostructured nickel hydroxide(Ni(OH)_2) via sonochemical technique is reported in the present study. The X-r
Microstructure, hydrogen storage and electrochemical performances of Co-added La0.75Mg0.25Ni3.5?xCox (x=0, 0.2, 0.5 at%) alloys are studied. XRD and rietveld re
