Advanced Functional Materials, EarlyView.The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime
Advanced Functional Materials, EarlyView.A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.

School building conditions and student achievments: Norwegian evidence [PDF]
This paper studies the effects from poor school building conditions on student achievements in Norwegian primary schools based on results from national tests in mathematics, English and Norwegian. The benchmark OLS results suggest a negative relationship,

Rapid Diagnostics of Reconfigurable Intelligent Surfaces Using Space‐Time‐Coding Modulation
Advanced Functional Materials, EarlyView.A fast reconfigurable‐intelligent‐surface (RIS) diagnostics method is proposed based on spatio‐temporal modulation with orthogonal codes. Theoretical analysis demonstrates a clear distinction in code channel power between normal and faulty elements. Simulations validate its feasibility under high fault ratios and varying receiving angles.

Advanced Functional Materials, EarlyView.A suspension of metal‐organic nanosheets was centrifuged to form self‐healing gels with a hierarchically porous structure. The prepared gels were used to selectively capture small molecules from solutions and differentially release them based on their size and charge. Abstract Metal‐organic nanosheets (MONs) are intrinsically porous 2D materials with a
