Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

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 ...

Semiconducting THO‐C3N Monolayers for Ultrahigh Anisotropic Carrier Mobility

Advanced Science, EarlyView.
A precise site‐specific N‐doping strategy that drives a secondary electronic transition in net W is proposed, enabling the electronic properties transition from metal to Dirac semimetal and ultimately to semiconductor. The obtained THO‐C3N‐2 and THO‐C3N‐3 semiconductors exhibit high carrier mobilities and pronounced mobility anisotropy, with THO‐C3N‐2 ...

Beyond Traditional RAFT Polymerization: Emerging Strategies and Future Perspectives; A Third Update

Advanced Science, EarlyView.
This review explores recent advances in the past five years for non‐traditional RAFT polymerization, focusing on new activation strategies, sustainable depolymerization, and integration with automated and AI‐driven synthesis. Together, these innovations advance polymer chemistry and reveal how the pieces of the non‐traditional RAFT puzzle are steadily ...

Persistent Magnetism and Tunable Doping of Monolayer Graphene via Europium Density Modulation

Advanced Science, EarlyView.
The modulation of europium density at the graphene/rhenium interface enables electron doping of monolayer graphene both beneath and beyond the van Hove singularity. The interfacial europium is ferromagnetic, with a transition from a mixed Eu(II)/Eu(III) valence in the dense phase to a pure Eu(II) state in the diluted phase.
