Advances in Solution‐Processed Textile Triboelectric Nanogenerators: Ink Formation, Processing Strategies, Applications, and Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Advanced ink systems for solution‐processed textile triboelectric nanogenerators are systematically summarized, spanning conductive, tribo‐negative, and tribo‐positive layers. By connecting ink chemistry, deposition methods, and device function, the present review reveals the key governing principles of solution development and highlights practical ...

Autonomous Multi‐Objective Nanoscale Characterization of Combinatorial (Al, Sc, B)N Films Reveals Composition‐Dependent Ferroelectric Regimes

open access: yesAdvanced Functional Materials, EarlyView.
Autonomous scanning probe microscopy and multi‐objective Bayesian optimization navigate a ternary (Al,Sc,B)N combinatorial library. Registered photoluminescence, electron‐probe compositional mapping, and X‐ray diffraction connect local electromechanical function to defect‐sensitive emission, composition, and crystal structure.

Rib Thickness Optimization of Vibration Test Fixture Based on Orthogonal Array for Weight Reduction

open access: yesMathematics
Vibration test fixtures are widely used to evaluate the dynamic characteristics of structures. However, their performance is often limited by their excessive weight and unintended resonances. Conventional optimization methods, such as genetic algorithms,

Dual‐band orthogonal polarised shared aperture array with shared‐elements

open access: yesElectronics Letters, 2021
In this paper, an orthogonal polarised dielectric resonator antenna (DRA) which can operate at S‐ and C‐band, has been designed as “shared‐element” for forming a dual‐band shared aperture array.

On existence and number of orthogonal arrays

open access: yesJournal of Combinatorial Theory, Series A, 1988
The authors show that for significantly large \(\lambda\) an orthogonal array \(A_ t(v,k,\lambda)\) exists for all (v,k,\(\lambda\),t) and that a signed orthogonal array \(SA_ t(v,k,t)\) exists for all (v,k,\(\lambda\),t), \(k\geq t\). As in \textit{N. M. Singhi} and \textit{S. S. Shrikhande} [A reciprocity relation for t-designs, Eur. J. Comb.

Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

open access: yesAdvanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

A Residue Number System Based Parallel Communication Scheme using Orthogonal Signaling: Part I-System Outline

open access: yes, 2002
A novel signaling scheme is presented, where a set of orthogonal signals is transmitted in parallel. The signals are selected according to the so-called residue number system (RNS).

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

open access: yesAdvanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...
