Excellent Comprehensive Electromechanical Properties in PZT‐Based Hard High‐Temperature Piezoceramics

Rare Metals, EarlyView.
ABSTRACT High‐power piezoelectric ceramics which have a wide operating temperature range are essential for sensor and actuator applications in extreme conditions. However, their development is fundamentally hindered by the inherent trade‐off among key parameters (TC, d33, Qm).

Synthesis of Amorphous‐Crystalline Mixture Boron Nitride for Balanced Resistive Switching Operation

Small, EarlyView.
An amorphous–crystalline mixture BN (acm‐BN) is synthesized through low‐pressure chemical vapor deposition, achieving balanced resistive switching with low SET voltage and stable RESET. High‐resolution transmission electron microscopy reveals that BN films are fully amorphous at 930 °C, a mixed amorphous–crystalline phase is achieved at 990 °C.

MnBr2${\rm MnBr}_2$ on the Graphene on Ir(110) Substrate: Growth, Structure, and Super‐Moiré

Small, EarlyView.
The study realizes single‐layer MnBr2${\rm MnBr}_2$ via molecular beam epitaxy on graphene on Ir(110), unveiling a unique super‐moiré (“moiré of moirés”) formed by lattices of different symmetries. Remarkably, this super‐moiré is driven by a virtual interaction between non‐contacting layers.

Impact of Structural Heterogeneities in Hierarchically Grown Microribbons on 2D WS2 Monolayer on the Measured Local Hydrogen Evolution Activity on Au Substrate

Small, EarlyView.
Spatially resolved SECCM measurements reveal that hierarchically grown microribbons on 2D WS2 drastically suppress local HER activity. Relative to the basal plane of the 2D monolayer directly supported on an Au substrate, single‐layer and multilayer microribbons exhibit more than a ∼5‐fold and >10‐fold decrease in current density, respectively.

GRAPH-PROJECTION MOIRE METHOD OF MEASUREMENT OF SURFACE OBJECT

Известия высших учебных заведений: Нефть и газ, 2014
The article presents the principle of the implementation of graph-projection moire method and its differences from existing optical measuring methods. Based on the experiment, a comparison is exactly the shadow moire and graph-projection moiré methods.

Förster valley-orbit coupling and topological lattice of hybrid moiré excitons

Communications Physics
Hybrid excitons in moiré superlattices of two-dimensional (2D) semiconductors inherit the electric dipole, strong moiré trapping, and stacking optical selection rules from its interlayer part, whereas the intralayer part is intended for enhancing optical

Interface‐Engineered Bi0.5Sb1.5Te3/WSe2 Heterostructures for Enhanced Thermoelectric Performance

Small, EarlyView.
BST/WSe2 heterostructures grown by pulsed laser deposition exhibit semicoherent van der Waals interfaces, characterized by lattice strain, compressed gaps, and localized moiré patterns. These interfacial features modulate carrier generation and energy filtering, yielding high Seebeck coefficients and a consistently high power factor above 50 µW cm−1 K ...

A New Platform for Twistronics: Perovskite Moiré Superlattices Beyond van der Waals

Small Structures
Moiré superlattices have reshaped condensed‐matter physics by enabling twist‐angle engineering of electronic and excitonic states, traditionally in van der Waals (vdW) systems. This Perspective focuses on perovskites as a transformative non‐van der Waals
