Mechanoluminescence of Bi‐Activated NaYGeO4 Polycrystals and 3D Printed Scaffolds in the NUV/Blue and NIR Spectral Range

open access: yesAdvanced Optical Materials, EarlyView.
NUV/Blue and NIR emitting mechanoluminescent (ML) materials based on a Bi‐doped germanate compound (NYGOBx) are reported. 3D‐printing is used to fabricate complex scaffold devices from this material, suggested for use as mechanically‐activated light sources for functional illumination.

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Improving Light Outcoupling and Addressing Measurement Specifics in Perovskite Light‐Emitting Diodes with Light Management Foils

open access: yesAdvanced Photonics Research, EarlyView.
The necessity and feasibility of enhancing light outcoupling in perovskite light‐emitting diodes (PeLEDs) is highlighted. On near‐IR PeLEDs, low‐cost, micro‐textured light management (LM) foils demonstrate boost in light extraction. Optimizing perovskite thickness and the optical cavity in synergy with LM foils is crucial for maximizing performance ...

Predicting Fiber Length Characteristics of Recycled Cotton and Cellulose Fiber Blends Using Machine Learning Models

open access: yesAdvanced Theory and Simulations, EarlyView.
This study explores machine learning‐driven prediction of fiber length characteristics in sustainable yarn blends made from recycled cotton and Lyocell. By analyzing empirical data through models like Random Forest and Gradient Boosting, and interpreting results with SHAP, key fiber length features from the Staple Diagram and Fibrogram are identified ...

Approximation theory in combinatorial optimization. Application to the generalized minimum spanning tree problem

open access: yesJournal of Numerical Analysis and Approximation Theory, 2005
We present an overview of the approximation theory in combinatorial optimization. As an application we consider the Generalized Minimum Spanning Tree (GMST) problem which is defined on an undirected complete graph with the nodes partitioned into ...
