d‐Wave Fermi Surface Instability in the Nematic Phase of Two Monolayer FeSe/SrTiO3

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Angle‐resolved photoemission spectroscopy reveals a d‐wave nematic order in two‐monolayer FeSe/SrTiO3, showing degenerate dxz/dyz bands at Γ but a pronounced splitting at M. This momentum‐dependent anisotropy identifies the nematicity as a d‐wave Fermi surface (Pomeranchuk) instability, highlighting 2D FeSe as a model platform to explore the interplay ...

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

Advanced 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

Advanced 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?

Advanced 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.

Experimental methods in chemical engineering: Electrospinning

The Canadian Journal of Chemical Engineering, Volume 104, Issue 2, Page 556-568, February 2026.
Abstract Electrospinning produces micro‐ and nanofibres by forcing a polymeric solution through a fine needle in an electric field that produces a filament that accumulates onto a collector plate. The fibre morphology depends on solution properties, distance between needle and plate, feed rate, and electric field intensity.

Modulation of Radiative Heat Transfer at the Nanoscale via Topological Polaritons in Twisted van der Waals Crystals

Nanophotonics, Volume 15, Issue 2, 27 January 2026.
Twisted α‐MoO3 layers support phonon polaritons whose propagation depends on the twist angle, enabling control of near field radiative heat transfer. Increasing the angle yields a monotonic rise in heat flux, driven by topological transitions from open hyperbolic to closed elliptical dispersions.
