Identification and Reversible Optical Switching of NV+ Centers in Diamond
Advanced Functional Materials, EarlyView.NV+ centers in diamond are predicted to coexist with NV0 and NV– centers, but direct experimental confirmation remains challenging. Using positron annihilation spectroscopy with in situ light illumination, a charge transition NV+/0 is observed at 1.234(8) eV.

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films
Advanced Functional Materials, EarlyView.This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

Fully Bio‐Based Epoxy Resins from Liquefied Wood for Chemically Recyclable Wood Coatings
Advanced Functional Materials, EarlyView.A bio‐based and chemically recyclable epoxy resin derived from liquefied wood and its use in wood coatings is presented. The resin exhibits mechanical, thermal, and water‐resistant properties comparable to commercial coatings and can be chemically recycled and reused. This approach provides fast access to glossy and fully biobased durable wood coatings
