Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens

open access: yesAdvanced Healthcare Materials, EarlyView.
High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.

Self‐Cooling Molecular Spin Qudits

open access: yesAdvanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

open access: yesAdvanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination
