Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.Heterogeneous‐catalyzed selective and versatile hydrogenative functionalizations of phthalimides have been developed for the first time. By using a solid nanocomposite formed by [Ag/Al2O3] material in combination with [H‐BETA] zeolite as cocatalyst, a broad range of 3‐functionalized isoindolinones have been accesed in one‐pot from phthalimides, H2 and ...

Mechanical Glass‐Backsheet Photovoltaic Modules Delamination: Toward Materials Recycling
Advanced Energy and Sustainability Research, Volume 7, Issue 2, February 2026.A new technology based on sanding has been developed to collect most of the materials contained in a photovoltaic (PV) module in the form of powders. A pilot line is now operational. This technology is specifically suited for Glass//Backsheet PV panels, which represent today the vast majority of the end of life PV panels.
