Advanced Science, EarlyView.Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Advanced Science, EarlyView.A reservoir‐guided silver‐nanoparticle soldering strategy is developed for bending‐resistant 3D graphene–metal heterojunctions. Controlled hot‐plate evaporation confines conductive ink within the metal reservoir, suppressing spreading and protecting the LIG interface from deformation‐induced fracture.

Minimizing Age of Information in Slotted ALOHA With Short-Packet Communications
IEEE AccessAge of information (AoI) has emerged as a novel metric for quantifying the freshness of information at the receiver side. This metric has found numerous applications in real-time monitoring and control systems where stale information may lead to critical

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review
Advanced Science, EarlyView.Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

Sub‐Terahertz Memristor Switches Using MoS2 by Liquid–Liquid Interface Assembly
Advanced Science, EarlyView.This work introduces application‐ready sub‐terahertz memristor switches fabricated from electrochemically exfoliated MoS2 nanosheets assembled at a liquid–liquid interface. The devices exhibit robust unipolar resistive switching, low insertion loss, and high isolation across 10–110 GHz.

Advanced Science, EarlyView.This work demonstrates a paradigm‐shifting strategy to simultaneously achieve broadband wavelength tunability and single‐mode control within a single perovskite microwire structure. Using a facile heating‐assisted solid–solid anion‐exchange strategy, we synthesized phase‐pure CsPbClxBr3‐x microwires that exhibit the widest reported continuous lasing ...
