Superconducting Carbon‐Cage Network with Tc of 109 K at Ambient Pressure
Advanced Science, EarlyView.By introducing elemental and hole doping into a theoretically designed sp3‐hybridized C18 carbon cage, superconductivity with a transition temperature up to 109 K is predicted under ambient pressure. These findings offer a promising pathway for designing high‐Tc superconductors based on stable covalent carbon frameworks.

Enhanced Spectral Tunability by Sub‐10 nm Nanogaps in Graphene‐Metal Hybrid Metasurfaces
Advanced Science, EarlyView.A tunable mid‐infrared metasurface integrating graphene and metal antenna arrays with sub‐10 nm nanogaps is presented, overcoming the ≈20 nm limit of conventional fabrication. The enhanced spectral tuning range and modulation depth are enabled by combining electron‐beam lithography, thin metal deposition, and directional ion milling to precisely define

Advanced Science, EarlyView.In this work, the authors systematically investigate how Ni substitution regulates the magneto‐structural coupling and their functional consequences in the MnCoGe‐based compounds. Geometric nonlinear theory analysis reveals that Ni modification change of magneto‐structural transition can alleviate the lattice incompatibility, thereby broadening the ...

Layer‐By‐Layer Approach to Improve the Capacitance of Conducting Polymer Films
Advanced Electronic Materials, EarlyView.This work describes the synthesis and characterization of a composite material based on poly(3,4‐ethylenedioxythiophene) (PEDOT) and poly(3,4‐ethylenedioxypyrrole) (PEDOP) deposited in a layer‐by‐layer approach. Due to the developed electroactive area coming from the presence of 3D nanostructures, PEDOT/PEDOP demonstrates superior areal capacitance ...
