Halin's Grid Theorem for Digraphs

Journal of Graph Theory, EarlyView.
ABSTRACT Halin showed that every thick end of every graph contains an infinite grid. We extend Halin's theorem to digraphs. More precisely, we show that for every infinite family ℛ ${\rm{ {\mathcal R} }}$ of disjoint equivalent out‐rays there is a grid whose vertical rays are contained in ℛ ${\rm{ {\mathcal R} }}$.

Non‐Uniform Programmable Photonic Waveguide Meshes

Laser &Photonics Reviews, EarlyView.
Integrating defect cells into uniform hexagonal waveguide meshes overcomes the fundamental spectral and temporal limitations of programmable photonics. By leveraging the Vernier effect through non‐uniform coupled cavities, this architecture achieves a tenfold increase in free spectral range and ultra‐fast sampling times, paving the way for next ...

MXenes in Next‐Generation Light‐Emitting Diodes: Innovations, Challenges, and Future Prospects

Laser &Photonics Reviews, EarlyView.
This review provides a systematic and critical overview of MXene integration in LEDs from their synthesis strategies and electronic characteristics to their roles as electrodes, interlayers, and emissive materials. It also explores the emerging prospects and challenges for MXene‐enabled flexible, transparent, and intelligent display technologies that ...

Hierarchically Porous Coatings for Cellulose Fibers by Core–Shell Particle Templating

Macromolecular Rapid Communications, EarlyView.
Hybrid and functional core–shell particles comprising a silica core and a polymer shell were synthesized and used to develop a coating and etching process applied to a cellulose substrate. This resulted in highly porous, functional coatings on a cellulose membrane for further application in cellulose‐based adsorbers and advanced membrane technology ...

DeepSeek‐Lattice‐KG: A Compact Language Model With Knowledge Graph Augmentation for Lattice Structure Design

Materials Genome Engineering Advances, EarlyView.
DeepSeek‐Lattice‐KG integrates a domain‐adapted 14B LLM with a Neo4j lattice knowledge graph distilled from 50,000 papers. It analyzes queries, retrieves supporting subgraphs, and generates grounded answers; on a 2100‐question, six‐domain benchmark, it achieves 94.8% accuracy.
