Advanced Functional Materials, EarlyView.Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Xeno‐Free Biocompatible Peptide‐Based Bioinks Reinforced with Cellulose Nanofibers for 3D Printing
Advanced Healthcare Materials, EarlyView.A xeno‐free bioink combining self‐assembled peptides and cellulose nanofibers is developed for 3D printing. The bioink forms a non‐cross‐linked 3D scaffold, mimicking the extracellular matrix and supporting over 95% cell viability. This approach offers enhanced biocompatibility and mechanical stability, advancing 3D printing for personalized medicine ...

Infinitely Many Sign-Changing Solutions for Some Nonlinear Fourth-Order Beam Equations
Abstract and Applied Analysis, 2013 Several new existence theorems on positive, negative, and sign-changing solutions for the following fourth-order beam equation are obtained: u(4)=f(t,u(t)), t∈[0,1]; u(0)=u(1)=u′′(0)=u′′(1)=0, where f∈C([0,1]×ℝ1,ℝ1).
