Dicationic Ion‐Pair Doping Enables Stable and High‐Performing Conducting Polymers for Organic Thermoelectrics

open access: yesAdvanced Science, EarlyView.
TAB–2TFSI enables efficient ion‐pair doping across a wide range of conjugated polymers, where the strongly oxidizing TAB core drives charge transfer, and the TFSI counterions promote favorable ionic compensation. This dicationic dopant promotes uniform dopant distribution, improves structural order, and increases carrier delocalization, establishing a ...

Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies

open access: yesAdvanced Science, EarlyView.
A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.

Engineering Large‐Grain Metal Halide Perovskite Films via Chemical Vapor Deposition for High‐Performance, Ultralow‐Noise Perovskite Photodetectors

open access: yesAdvanced Science, EarlyView.
Chemical vapor deposition produces large‐grain, phase‐pure CsPbBr3 films (grains up to 35 µm) with Drude‐like terahertz photoconductivity and twofold higher carrier mobility versus spin‐coated references. These microstructural advances translate into photodetectors with a detectivity of 8.4 × 1012 Jones, dark current below 1 pA cm−2, X‐ray sensitivity ...

Nanoscale Confinement Enhances Ultrafast Demagnetization

open access: yesAdvanced Science, EarlyView.
Next generation spintronics may depend on successfully combining femtosecond spin dynamics with nanoscale device miniaturization. We address this by systematically studying the effect of nanoscale confinement on the femtosecond demagnetization of Iron. By combining ultrafast experiments sensitive to spins, charge carriers, and phonons, we uncover a nm ...

F‐Type Pyocin Versus Phage λ Tail: Conserved Hub, Divergent Fibers

open access: yesAdvanced Science, EarlyView.
Near‐atomic cryo‐EM structures of a Gram‐negative F‐type pyocin reveal a conserved tail tip architecture shared with bacteriophage λ together with a previously unrecognized side‐fiber attachment mode. These findings provide new insight into tailocin assembly and host recognition and establish a structural framework for engineering precision ...
