TL;DR: In this paper, a study on the electrocatalytic performances of nickel-cobalt alloys for hydrogen evolution in alkaline media has been carried out, and the synergism among the nickel catalytic properties, having low hydrogen over-potential and high hydrogen adsorption of cobalt, is best realized in this conditions and allow obtaining the largest value of exchange current density.

TL;DR: The presence of LiCoO(2) and LiCo(x)Ni((1-x))O( 2) in the cathodic material of Li-ion and Li-polymer batteries has stimulated the recovery of Co and Ni by hydrometallurgical processes, and the Co powder appears particularly suitable for Co recycling as cobaltite in new batteries.

TL;DR: The results obtained by SEM measurements suggest that an increase in the particles size accompanied by a noticeable aggregation of TiO2 nanoparticles is due to high temperatures achieved during the thermal treatments and confirmed the presence of different content of the two crystalline phases of titanium dioxide.

TL;DR: In this article, the results highlight a linear correlation between bath and deposit Co/Ni ratio, with slope change for Co concentration in the electrolyte higher than 3 ǫg/L.

TL;DR: In this paper, the thermal properties of the synthesized gel-glass materials were studied as a function of the Ca/P molar ratio using thermogravimetric and differential thermal analysis (TG/DTA).
