Introducing Pure Calcium Orthophosphate Gels and Aerogels
Advanced Functional Materials, EarlyView.The synthesis of calcium phosphate‐based gels and aerogels is reported, which exhibit highly porous structures built up of networks of nanoparticles. In case of amorphous aerogels, this leads to yet unmatched specific BET surface areas, making these materials especially interesting for biomedical applications.

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers
Advanced Functional Materials, EarlyView.Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...

Advanced Functional Materials, EarlyView.Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications
Advanced Functional Materials, EarlyView.Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus
Advanced Functional Materials, EarlyView.The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...
