Robust Photocatalytic Hydrogen Evolution Over a Conjugated Metal‐Organic Framework Heterojunction

open access: yesAdvanced Science, EarlyView.
We report a conjugated coordination polymer, Cd‐TMT (TMT = 1,3,5‐trimercaptotriazine), featuring an intrinsic molecular‐level charge transport network. The conjugated TMT ligands facilitate strong intra‐ligand charge transfer, while their ordered π‐π stacking along the [111] direction establishes a continuous pathway for directional electron migration,

Toward High‐Resolution Polymeric Neural Interfaces: A Practical Guide for Electron Beam Lithography

open access: yesAdvanced Science, EarlyView.
Electron beam lithography (EBL) enables sub‐micron patterning of polymer‐based neural implants, overcoming the resolution limits of optical lithography. By addressing challenges such as charging, non‐planarity, and substrate heating, it supports higher channel density, improved miniaturization, and better long‐term tissue integration.

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 ...

Introducing Family Tax Splitting in Germany: How Would It Affect the Income Distribution and Work Incentives [PDF]

open access: yes
We analyze the effects of three alternative proposals to reform the taxation of families relative to the current German system of joint taxation of couples and child allowances: a French-type family splitting and two full family splitting proposals.

Programmable Topological Magnetic Textures in Above‐Room‐Temperature 2D Ferromagnet Fe3GaTe2

open access: yesAdvanced Science, EarlyView.
This work demonstrates the programmable generation and deterministic modulation of magnetic skyrmion bags with high‐order topological numbers in the above‐room‐temperature 2D ferromagnet Fe3GaTe2 (FGaT) via current‐pulse control. Furthermore, highly efficient electrical manipulation and current‐driven parallel motion of these high‐order topological ...

Origin of Enhanced Efficiency and Reduced Roll‐Off in Organic Light‐Emitting Diodes Based on Pt(II) Complexes

open access: yesAdvanced Science, EarlyView.
Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...

Observation of Magnetic‐Anisotropy Crossover and High‐Temperature Skyrmions in the Dirac Magnet Fe3Ge with a Distorted Kagome Lattice

open access: yesAdvanced Science, EarlyView.
A temperature‐driven magnetic anisotropy crossover is revealed in the Dirac kagome magnet Fe3Ge with a distorted kagome lattice. The transition from easy‐plane to easy‐axis magnetic anisotropy stabilizes robust Bloch‐type skyrmions over an exceptionally wide temperature window of 375–650 K.

Colossal Magnetic‐Field‐Induced Anomalous Hall Conductivity in a Kagome Antiferromagnet YMn6Sn6

open access: yesAdvanced Science, EarlyView.
Magnetic‐field‐driven spin canting in the kagome antiferromagnet YMn6Sn6${\rm YMn}_6{\rm Sn}_6$ reshapes flat and Dirac bands near the Fermi level, redistributing Berry curvature and producing colossal anomalous Hall conductivity. The study reveals how magnetic configuration and clean‐limit skew scattering cooperate to amplify Hall transport, offering ...
