Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials

open access: yesAdvanced 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 ...

Integrated Ovonic Threshold Switching Selector and Resistive Switching Memory 1S1R in Electrodeposited ZnTe Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
This study showcases the first‐ever demonstration of ovonic threshold switching (OTS) and resistive switching (RS) in ZnTe thin films fabricated via a fast, cost‐effective electrodeposition method. By controlling the deposition potential, ZnTe film is tuned to demonstrate OTS or RS behaviors, enabling the implementation of one‐selector‐one‐resistor ...

Polarization‐Dependent Color Modulation in Electrodeposited Cellulose Nanocrystals and Birefringent Multilayers

open access: yesAdvanced Optical Materials, EarlyView.
This work demonstrates that wavelength selective reflection of circularly polarized light (CPL) of both handedness (right‐R or left‐L) can be achieved from self‐assembled cellulose nanocrystals (CNCs), breaking the inherent limitation of obtaining only L‐CPL reflection.

Predictive Design to Determine Optimal Absorber Placement in Colloidal Photonic Crystals

open access: yesAdvanced Optical Materials, EarlyView.
The inclusion of absorbing material is known to increase color saturation in photonic crystals. Predictive design based on mathematical structure optimization is used to identify optimal designs for the absorber amount and position within a photonic colloidal crystal and experimentally realized. This strategy shows that the placement of the absorber at

Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

open access: yesAdvanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...
