A Dual‐Piezoelectric Metal–Organic Cage/COF Z‐Scheme Heterojunction for Solar‐Mechanical Water Splitting

Advanced Science, EarlyView.
A dual‐piezoelectric Z‐scheme heterojunction is constructed by integrating a piezoelectric metal–organic cage (MOC‐FA3) with a β‐ketoenamine‐linked covalent organic framework (S‐COF). This design enables efficient solar‐mechanical energy conversion, achieving remarkable piezo‐photocatalytic pure water splitting for simultaneous H2 and H2O2 production ...

Advances in Thermoelectric Thin Films Grown by Atomic Layer Deposition: A Critical Review of Performance and Challenges

Advanced Energy Materials, EarlyView.
This review highlights the use of atomic layer deposition (ALD) for fabricating thermoelectric thin films with atomic‐scale control. Four material classes—chalcogenides, doped oxides, ternary oxides, and multilayered structures—are compared in terms of growth dynamics, structure–property relationships, and thermoelectric performance. The precise tuning

Mechanical Glass‐Backsheet Photovoltaic Modules Delamination: Toward Materials Recycling

Advanced Energy and Sustainability Research, EarlyView.
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.

Topology‐Aware Machine Learning for High‐Throughput Screening of MOFs in C8 Aromatic Separation

Advanced Intelligent Discovery, EarlyView.
We screened 15,335 Computation‐Ready, Experimental Metal–Organic Frameworks (CoRE‐MOFs) using a topology‐aware machine learning (ML) model that integrates structural, chemical, pore‐size, and topological descriptors. Top‐performing MOFs exhibit aromatic‐enriched cavities and open metal sites that enable π–π and C–H···π interactions, serving as ...
