Closed‐Loop Solid‐State Synthesis Planning for Materials Discovery With Large Language Models
Advanced Materials, EarlyView.Leveraging literature data, we build a large‐language‐model‐driven workflow that extracts synthesis steps from 4407 papers, retrieves similar precedents, and generates candidate solid‐state synthesis recipes. The system benchmarks against ground‐truth and then operates in a closed loop with experiments to synthesize oxy‐selenide electrolyte materials ...

Efficient Wireless Near-Field Links Between Bessel-Beam Launchers
IEEE Open Journal of Antennas and PropagationThe focused nature of Bessel beams allows for secure and efficient wireless links in the near-field region. Still, at millimeter waves, few studies analyze the transmission efficiency between devices in a systematic way. In addition, present studies only

Accurate Ray-Tracing Modeling of Radiation From Leaky-Wave Antennas
In this letter, we propose the use of a radial ray-tracing approach to accurately model the radiation from leaky-wave antennas (LWAs). The technique involves the launching of several sets of rays that emanate radially from different source points along ...

Defect‐Templated Phase Engineering in Atomically Thin Metals
Advanced Materials, EarlyView.Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...
