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 ...

Interplay Between Acoustical and Mechanical Properties in Lattice Structures: A Geometrical Perspective

Advanced Materials Technologies, EarlyView.
This perspective presents an in‐depth analysis of the structural‐property relationships between acoustic and mechanical properties in lattice structures. It introduces the concept of “acoustical geometry” and identifies the limitations of traditional lattice designs in simultaneously optimizing sound absorption and mechanical performance.

Building Scalable Silicon Microring Resonator‐Based Neuromorphic Photonic Circuits Using Post‐Fabrication Processing with Photochromic Material

Advanced Optical Materials, EarlyView.
One of the high‐impact research goals in neuromorphic photonics is to build scalable photonic artificial intelligence computing at high energy efficiency. This perspective paper discusses microring resonator (MRR)‐based large‐scale photonic neural networks, variations of MRR resonance wavelength from fabrication, and post‐fabrication processing with ...

Understanding the Optoelectronic Processes in Colloidal 2D Multi‐Layered MAPbBr3 Perovskite Nanosheets: Funneling, Recombination and Self‐Trapped Excitons

Advanced Optical Materials, EarlyView.
Mechanisms by which excitons and charge carriers can funnel and recombine in 2D multi‐layered MAPbBr3 Ruddlesden‐Popper perovskite nanosheets are missing. This femtosecond transient absorption spectroscopy study creates a comprehensive understanding of how directed transport, exciton‐exciton annihilation, and Auger recombination occur in colloidal ...
