Microstructural Evolution Dominates the Changes in the Thermal Conductivity of Conjugated Polymers Upon Doping

Advanced Functional Materials, EarlyView.
The relationship between the doping induced microstructure and thermal conductivity changes is elucidated for conjugated polymers. Eight conjugated polymers with different doping systems are studied, showing varied thermal conductivity responses based on structural order.

Magnetic‐Field Tuning of the Spin Dynamics in the Quasi‐2D Van der Waals Antiferromagnet CuCrP2S6

Advanced Functional Materials, EarlyView.
This study reveals 2D character of the spin dynamics in CuCrP2S6, as well as complex field dependence of collective excitations in the antiferromagnetically ordered state. Their remarkable tuning from the antiferromagnetic to the ferromagnetic type with magnetic field, together with the non‐degeneracy of the magnon gaps favorable for the induction of ...

Self‐Assembled Membranes for High Ion Selectivity and Proton Blocking in Electrochemical Applications

Advanced Functional Materials, EarlyView.
Phase‐separated alkyl poly(vinylimidazolium) membranes exhibit exceptional ionic conductivity, counter‐ion selectivity, and proton‐blocking ability by forming stable micro/macrophase‐separated domains. This design overcomes the conductivity–selectivity trade‐off in conventional ion‐exchange membranes (IEMs), offering a new paradigm for high‐performance

Nitrogen‐Vacancy Magnetometry of Edge Magnetism in WS2 Flakes

Advanced Functional Materials, EarlyView.
Using nitrogen‐vacancy magnetometry, the authors visualize room‐temperature stray magnetic fields localized at the edges of WS2 flakes. Their measurements reveal edge‐specific magnetization consistent with spin canting in antiferromagnetically coupled edge states.

SMaRT Stacking: A Methodology to Produce Optimally Layered EMI Shields with Maximal Green Index Using Fused Deposition Modeling

Advanced Functional Materials, EarlyView.
Electromagnetic interference (EMI) shields consisting of polylactic acid (PLA) in layers with different concentrations of multiwalled carbon nanotubes (MWCNT) are produced using additive manufacturing. The permittivity function of layers with different filler concentrations is learned using data of homogeneous and randomly ordered shields.

Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals

Advanced Functional Materials, EarlyView.
In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

Direct Evidence of Topological Dirac Fermions in a Low Carrier Density Correlated 5d Oxide

Advanced Functional Materials, EarlyView.
The 5d oxide BiRe2O6 is discovered as a low‐carrier‐density topological semimetal hosting symmetry‐protected Dirac fermions stabilized by nonsymmorphic symmetries. Angle‐resolved photoemission spectroscopy, quantum oscillations, and magnetotransport measurements reveal gapless Dirac cones, quasi‐2D Fermi surfaces, high carrier mobility, and a field ...
