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

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
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.

Approaching the Monolayer Limit of Carbon Layers by Pyrolysis of Polymer Films

open access: yesAdvanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
Wafer‐scale functional devices based on pyrolyzed photoresist films are synthesized directly on target substrates without catalysts or transfer steps, with channels reaching the monolayer limit (0.34 nm). X‐ray photoelectron spectroscopy confirms predominant sp2 character, Raman spectroscopy reveals evolving nanocrystallinity, and transmission electron

Is There A Pure Electronic Ferroelectric?

open access: yesAdvanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

Look‐up table correction for beam hardening‐induced signal of clinical dark‐field chest radiographs

open access: yesMedical Physics, Volume 53, Issue 2, February 2026.
Abstract Background The microstructure of material at a μm$\,\umu\mathrm{m}$ length scale leads to ultra‐small‐angle scattering of X‐rays, which typically occurs, e.g., for lung tissue or some plastic foams. When using an interferometer, this effect alters the visibility of the fringe pattern, which can be detected and resolved by the detector.
