Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials
Advanced Materials Technologies, EarlyView.This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue
Advanced Materials Technologies, EarlyView.A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...

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.

3D Printed Optics Achieves Broadband Structured Light
Advanced Optical Materials, EarlyView.The arbitrary creation of structured light often requires complex design and fabrication steps and is largely limited to single wavelength. By leveraging off the toolkit for digital holograms, how complex amplitude modulation can be implemented as 3D printed optics in a manner that is broadband is shown, for the creation of multiwavelength forms ...
