Epitaxial Interface‐Driven Photoresponse Enhancement in Monolayer WS2–MoS2 Lateral Heterostructures

Advanced Functional Materials, Volume 36, Issue 8, 26 January 2026.
Surface potential distribution image, along with the derived electric field distribution across the interface, reveals that the electric field reaches its peak at the interface. Additionally, the spectral response of the heterointerface exhibits higher and broader features compared to its bare counterparts.

Evaluating the respective role of individual precipitates on the hydrogen trapping ability and locations of a co-precipitation enameled steel via in situ Scanning Kelvin Probe Force Microscopy

Philosophical Magazine Letters
The fishscaling resistance of enameled steel is closely related to the hydrogen-related behaviour of its constituent phases, in which dispersed co-precipitates are regarded as the most effective hydrogen-trapping sites.

Strain‐Induced Piezo‐Optoelectronic Coupling in Monolayer MoS2

Small Structures, Volume 7, Issue 1, January 2026.
This work demonstrates direct piezo‐optoelectronic coupling in large‐area monolayer MoS2, where strain‐induced piezoelectric polarization modulates photocurrent generation. By linking nanoscale piezoresponse with device‐level photodetection, the authors show that mechanical strain serves as a controllable knob for exciton dissociation and charge ...

Corrosion behavior and mechanism of Mg–Er–Zn–Zr alloys in different states

Journal of Materials Research and Technology, 2022
The corrosion behavior and mechanism of as-cast, solid-solution treated, and as-extruded Mg-14.4Er-1.4Zn-0.3Zr (wt.%) alloys are investigated. The microstructure characteristic of as-cast alloy, i.e., the semi-continuous 18R-long period stacking ordered (
