High‐Entropy Magnetism of Murunskite
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Identification and Reversible Optical Switching of NV+ Centers in Diamond
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.

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.

Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis
The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.
