Finite and infinite element method applied to water wave diffraction problems [PDF]

open access: yes, 1999
In this work, three types of infinite elements are developed to solve the problem of linear water wave diffraction by objects in a 2D unbounded domain. The infinite elements, which model the far field wave potential stretching to infinity, are coupled to

Fritz-John Type Necessary Conditions for Optimality of Convex Generalized Semi-Infinite Optimization Problems

open access: yesJournal of Mathematical Extension, 2013
In this paper, we consider the Abadie and the Basic constraint qualifications (CQ) for lower level problem of convex generalized semi-infinite programming problems, and we derive the Fritz-John necessary optimality conditions for the problem under ...

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

open access: yesAdvanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Electromagnetic Properties of a Hybrid Solid-State Structure Incorporating a Plasma-Like Medium and a Metasurface

open access: yesEast European Journal of Physics
In this paper, we theoretically investigate the dispersion properties of surface and bulk-surface electromagnetic waves propagating in a hybrid layered solid-state structure containing an isotropic plasmonic metasurface. This structure consists of a semi-

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 ...

Oligoethylene Glycol Side‐Chain Engineering of Y6‐Derived Nonfullerene Acceptors for Thermally Induced Spontaneous Pseudo‐Planar Heterojunction Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
OEG‐functionalized Y6‐derived acceptors induce thermally driven vertical phase separation, enabling pseudo‐planar heterojunction organic photodetectors. The resulting PM6:YTEG‐4F and PM6:YTEG‐4Cl organic photodetectors suppress dark current density by approximately 260‐fold and 210‐fold, respectively, while maintaining efficient photoresponse ...

In Situ Magnetic Ordering and Microfabrication of Liquid Crystal Networks with Discretized Alignment

open access: yesAdvanced Functional Materials, EarlyView.
Miniaturizing liquid crystal network actuators typically demands costly laser writing or digital light processing. A low‐cost photolithography platform couples rotating photomasks with a Halbach magnetic array to discretize in‐plane molecular alignment down to 50 µm, producing programmable, light‐responsive grippers, checkerboards, and origami‐inspired
