Surprisingly, a thorough mechanical characterization showed that oxygen retained its high hardening capacity in Ti-Zr alloys but without any decrease in the associated ductility, contrary to what has been observed so far in titanium alloys. These alloys therefore have, in fact, excellent mechanical

The application of deep penetration laser welding of copper materials is limited by instabilities occurring at the vapour capillary and within the melt pool. Up to now, complex countermeasures, such as oscillation of the laser power or spatial beam oscillation, are applied to prevent the resulting f

While zeolites or Metal-Organic Frameworks (MOFs) are suitable in numerous fields involving adsorption-desorption processes, their poor electronic conductivity, associated to the nature of the constitutive bonds involving the very electronegative oxygen, is a noticeable drawback in every application

In terms of efficiency, as of today, multi-junction SC are the only concept to demonstrate performance overcoming the single-junction Schockley-Queisser limit (33%) and reach industrial applications.
