Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass

open access: yesAdvanced Functional Materials, EarlyView.
A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...

Unveiling Aggregation‐Induced Singlet Fission in Push–Pull Diketopyrrolopyrrole Water Dispersed Nanoaggregates and Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Aggregates of diketopyrrolopyrrole dipolar and quadrupolar systems exhibit panchromatic absorption spectra extending in the entire visible range. Upon aggregation in water and in the solid state, their fluorescence is almost completely quenched and their singlet excited state lifetime is significantly shortened.

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples

open access: yesAdvanced Functional Materials, EarlyView.
Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...

Analysis of the Electrochemical Stability of Sulfide Solid Electrolyte Dry Films for Improved Dry‐Processed Solid‐State Batteries

open access: yesAdvanced Functional Materials, EarlyView.
An adapted processing for solvent‐free argyrodite solid electrolyte films based on insights into degradation mechanisms of the widely used binder polytetrafluoroethylene is presented. By adapting the dry film processing, long‐term cycling in Si||NMC pouch cells is demonstrated over more than 1000 cycles with a capacity retention of more than 80%, and ...

3D Digital Light Processing of Redox‐Active Polymers for Electrochemical Applications

open access: yesAdvanced Functional Materials, EarlyView.
3D printing of electrochemically switchable conducting polymers is achieved by Digital Light Processing of redox‐active carbazole‐based polymer materials. Complex 2D and 3D architectures including dot arrays and pyramids clearly show the potential for novel 3D switchable electrochemical devices for sensors, electrochromic displays as well as 3D printed
