Advanced Materials Technologies, EarlyView.High speed Raman spectroscopy has various applications, e.g. the sequencing of proteins. However, low signal intensity coincides with the low measurement time. The study presents a protocol using only a small number of sensitive single‐photon detectors measuring optimized spectral regions.

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 ...

Exciton Diffusion in Two‐dimentional Chiral Perovskites
Advanced Optical Materials, EarlyView.Transport of light‐emitting excitons is demonstrated in 2D chiral perovskites via transient optical microscopy. The excitons are found to diffuse rapidly after the excitation followed by localization at longer time‐scales. Temperature‐dependent exciton propagation combined with photothermal deflection spectroscopy measurements reveal the role of ...
