THz‐Driven Coherent Phonon Fingerprints of Hidden Symmetry Breaking in 2D Layered Hybrid Perovskites
Advanced Materials, EarlyView.Intense THz pulses are employed to drive coherent phonons in 2D Ruddlesden‐Popper hybrid metal‐halide perovskites (HOIPs) from the (PEA)2(MA)n‐1PbnI3n+1 family, revealing mode‐selective spectroscopic signatures of inversion symmetry breaking in those nominally centrosymmetric materials. These findings provide a handle to decode nonlinear phonon driving

Beyond Conventional Cooling: Advanced Micro/Nanostructures for Managing Extreme Heat Flux
Advanced Materials, EarlyView.This review examines the design, application, and manufacturing of biomimetic or engineered micro/nanostructures for managing high heat‐flux in multi‐level electronics by enhancing conductive, convective, phase‐changing, and radiative heat transfer mechanisms, highlighting their potential for efficient, targeted thermal management, and future prospects.

Advanced Materials, EarlyView.Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

Advanced Materials, EarlyView.Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Advanced Materials, EarlyView.In this work, nonzero Berry curvature in photonic crystals is induced by breaking unit cell inversion symmetry through spatial shifts rather than geometrical modifications. This enables the design of ultraconfined topological states with subwavelength in‐plane field confinement and out‐of‐plane field isolation.

Ce Single Atom‐Engineered Amorphous/Crystalline Nanosheets for Enhanced Alkaline Water Electrolysis
Advanced Materials, EarlyView.We leveraged Ce single‐atom engineering to generate short‐range ordered crystalline nanodomains in amorphous RuOx for creating amorphous/crystalline nanojunctions, in an effort to regulate the water dissociation kinetics for enhanced HER. Specifically, the Ce‐doped crystalline nanodomains greatly reduce the energy barrier to water dissociation and ...

Manipulating Individual Topological Solitons and Bisolitons in an Electronic System
Advanced Materials, EarlyView.While localized topological modes in quantum materials promise loss‐less delivery of classical and quantum information, manipulating them individually has been challenging. This work succeeded in manipulating topological solitons formed along atomic wires on silicon surfaces with high reproducibility in various ways, including translating, transforming
