Highly Versatile Hydrogenative Functionalizations of Phthalimides Catalyzed by an Ag‐Alumina Zeolite Nanocomposite: One‐Pot Synthesis of 3‐Substituted Isoindolinones

open access: yesAdvanced 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 ...

Joint Stiffness Influence on the First-Order Seismic Capacity of Dry-Joint Masonry Structures: Numerical DEM Investigations

open access: yesApplied Sciences, 2022
Heritage masonry structures are often modelled as dry-jointed structures. On the one hand, it may correspond to the reality where the initial mortar was weak, missing, or has disappeared through time because of erosion and lixiviation. On the other hand,

Mechanical Glass‐Backsheet Photovoltaic Modules Delamination: Toward Materials Recycling

open access: yesAdvanced 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.
