Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

Advanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Self‐Assembled Heterosymmetric Structure with Tunable Polarization Optics for Reversible Matrix Encryption

Advanced Functional Materials, EarlyView.
Sustainable films with heterosymmetric structures, harmoniously integrating symmetry and asymmetry, are fabricated using cellulose nanocrystals and hydrophilic nanolignin via evaporation‐induced self‐assembly, which exhibit excellent multiple polarization optical properties.

Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials

Advanced Functional Materials, EarlyView.
A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.
