Holographic Whole‐Object Photopolymerization Preserving Director Alignment in Liquid Crystalline Actuators

open access: yesAdvanced Materials, EarlyView.
Holographic microlithography enables the fabrication of fully connected 3D liquid crystalline structures in a single exposure. The process maintains precise control over the director orientation within the entire object, preventing local director distortions typically observed in sequential printing.

Membrane Semi‐Permeability and Ion Selectivity in Chemiosmosis: Open Systems Volume Dependence of Electrolyte Chemistry

open access: yesAdvanced Materials Interfaces, EarlyView.
Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...

4D Printing of Multimaterial Flexible Magneto‐Active Polymers

open access: yesAdvanced Materials Technologies, EarlyView.
Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...
