Self‐Organized Growth of Catalyst‐Free Single Crystal WnO3n‐2 (n = 25) Nanowire Bundles on Si (111) via Selective He+ Ion Irradiation

Advanced Materials Interfaces, EarlyView.
A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.

Proton Conduction of a Hydrothermally Synthesized Hexaazatriphenylene‐Based Covalent Organic Framework

Advanced Materials Interfaces, EarlyView.
A quinone‐functionalized hexaazatriphenylene‐based covalent organic framework (HAQ‐COF) is synthesized, making HAQ‐COF a promising polymer electrolyte membrane material for polymer electrolyte fuel cells. HAQ‐COF exhibits high water retention at room temperature and atmospheric pressure, along with high thermal stability.

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

Advanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.

Crystallographic Insights into the Structural Heterogeneities of 2D Ruddlesden‐Popper Perovskite Films

Advanced Materials Interfaces, EarlyView.
2D Ruddlesden‐Popper phase perovskite (RPP) films for applications in photovoltaics are shown to exhibit structural heterogeneities at both microscopic and mesoscopic scales that can affect cross‐film charge carrier transport. The mechanisms of RPP film formation and the possible means to control film structure to optimize 2D perovskite solar cell ...

Mie‐Resonant Metasurfaces with Controlled Silicon Oxidation in Electron‐Beam Deposition

Advanced Materials Interfaces, EarlyView.
Electron‐beam deposition is optimized to prevent silicon oxidation by controlling chamber pressure and deposition rate, yielding refractive index values comparable to other methods. This tunability enables precise control of optical properties. Mie‐resonant metasurfaces exhibit strong, tunable collective resonances, allowing the fabrication of silicon ...
