Strain‐Field‐Induced Bandgap Opening in Bilayer Graphene

Small, EarlyView.
Bandgaps of up to 50 meV are opened in bilayer graphene through periodic in‐plane strain fields imposed by a three‐layer graphene/organic 2D crystal/graphene heterostructure. The bandgap originates not from bilayer formation itself, but from bond‐length modulation at domain boundaries.

Tailoring the Melting and Glass Transition Behavior of Zeolitic Imidazolate Frameworks via Ammonium Halide Salts

Small, EarlyView.
Ammonium halide salts serve as inorganic modifiers that lower the melting and glass transition temperatures of zeolitic imidazolate frameworks, enabling centimeter‐scale hybrid glasses and melt processing of otherwise unmeltable ZIF‐8. In situ imaging and pair distribution function analysis reveal salt infiltration, Zn─N bond disruption, and Zn–halide ...

Hydrogen Bonding in Graphene

Small, EarlyView.
The hydrogen concentration and binding energies in large area graphene are determined from effusion measurements. The samples are grown using chemical vapor deposition using deuterated methane and deuterium as readily identifiable isotopes. Total hydrogen concentrations of 1.2 ‐ 6.9 × 1013 cm−2 are obtained.

Emergent Chaos‐Like Dynamics of Spin–Orbit‐Torque‐Driven Magnetic Transitions

Small, EarlyView.
By combining anisotropy‐engineered nanometer‐scale nucleation sites with time‐resolved x‐ray holography and micromagnetic modeling, magnetization dynamics are directly imaged, revealing chaos‐like fluctuations and skyrmion shedding and highlighting the intrinsic complexity of spin‐orbit torque driven systems.

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress
