Modulating Stiffness and Shape of a Soft, Textile‐Based Structure Through Glass Transition of a Conductive Phase‐Changing Polymer

Advanced Materials Technologies, EarlyView.
A variable stiffness structure with shape morphing and shape memory capabilities made from layered textiles and 3D printing material is developed. Direct printing of cPLA on textile electrodes maximizes the electrodes' contact area. This work presents a new method for achieving variable stiffness in small segments of soft, deformable structures, using ...

Optimizing Metamaterial Inverse Design with 3D Conditional Diffusion Model and Data Augmentation

Advanced Materials Technologies, EarlyView.
A generative AI model, the 3D conditional diffusion model (3D‐CDM), is introduced to enhance the inverse design of voxel‐based metamaterials. A data augmentation technique based on topological perturbation expands the dataset, further improving generation quality and accuracy.

Elucidating and Biomimicking the Coloration Mechanisms Responsible for the Vibrant Blue Hues of the Common Kingfisher

Advanced Optical Materials, EarlyView.
This study reveals why the back feathers of a common kingfisher show various non‐iridescent blueish structural colors by analyzing the internal structures of the feathers. It demonstrates how structural differences lead to the different optical interactions, thereby producing different colors.

Supramolecular Design of Polymeric Random Lasers

Advanced Optical Materials, EarlyView.
This research investigates the application of PolyHIPE scaffolds as scattering media inRLs. By modifying the scaffold's morphology, pore size, and surface chemistry, the dye distribution within the material is precisely controlled, achieving a tunable laser threshold.
