Research on interfacial microstructure, mechanical properties, and damage behaviors of AZ91/GWZ831K bimetallic structures fabricated via wire-arc directed energy deposition

This study investigated the interfacial microstructure, mechanical properties, and tensile damage evolution behavior of AZ91/GWZ831K bimetallic structures fabricated by wire-arc directed energy deposition (WA-DED). Bimetallic specimens were prepared with two distinct deposition s...

Achieving simultaneous strength-ductility-corrosion optimization of solid-state additive friction stir deposited superlight Mg-Li alloy by a hybrid high flow rate Argon/CO₂ shielding atmosphere

High-performance Mg–Li alloys were fabricated via solid-state additive friction stir deposition under a mixed Ar/liquid CO₂ atmosphere, which addresses severe oxidation and unfavorable thermal cycling issues during additive manufacturing. Benefiting from optimized microstructures...

Quantum Pseudorandom Scramblers

Abstract. Quantum pseudorandom state generators ( PRSG s) have stimulated exciting developments in recent years. A PRSG , on a fixed initial (e.g., all-zero) state, produces an output state that is computationally indistinguishable from a Haar random state. However, pseudorandomn...

Tetrazole-Derived Bis(1,3,4-oxadiazole)Scaffolds:A Heterocyclic Connectivity with Enhanced Stability and Reduced Sensitivity

Abstract Resolving the inherent trade-off between high energy and thermal stability/sensitivity in energetic materials remains a long-standing challenge. In this work, a series of energetic compounds and their corresponding salts were synthesized by employing a bis(1,3,4-oxadiazo...

Dynamic Parameter Identification of a Lower-Limb Exoskeleton Using RLS–AGWO

Accurate dynamic parameters are required for model-based control of lower-limb exoskeletons, but limited excitation, transmission friction, and assembly-dependent uncertainty can degrade conventional estimates. This study examines a two-stage method that combines recursive least...

Evolution of carbide precipitation along the radial direction during erosion of large-caliber gun barrels

This study aims to establish a quantitative correlation between the evolution behavior of carbides in the barrel ablation layer and the local thermal history. Using the retired barrel chamber of large‑caliber 32CrNi3MoV steel as the research subject, we systematically studied the...

3D digitization of ancient city walls based on structured light scanning

To support the management and conservation of ancient city walls, high-quality 3D digital documentation should be systematically integrated into heritage documentation and monitoring processes. This paper presents a high-definition, large-scale 3D digitization method for ancient...

MultifunctionalSingle-Transistor Architecture Enabledby Nonvolatile Band Rearrangement in 2D Ferroelectric Tunneling Junction

Abstract A defining challenge for next-generation nanoelectronics is integrating diverse functionalities within a single device while strictly minimizing power consumption. Two-dimensional (2D) ferroelectrics, with their atomic-scale nonvolatility, offer a promising platform for...

Nature contact and adolescent paper-reuse behavior: place attachment versus climate anxiety in a two-wave study of Chinese adolescents

Nature contact is often linked to pro-environmental behavior, but the psychological processes connecting these experiences to later behavior remain unclear. This study examined reusing paper and compared two theoretically distinct pathways: a positive-bonding pathway through plac...

Orientation-tunable correlated Chern insulating states in chiral twisted double bilayer graphene proximitized by WSe2

Moiré flat bands in graphene systems proximitized by transition-metal dichalcogenides (TMDCs) provide a setting where spin-orbit coupling (SOC) can reshape band topology. The crystallographic alignment angle Φ between TMDC and graphene layers is predicted to tune the balance of I...

Three-Dimensional Nonconjugated Microporous Organic Polymers Based on Tröger’s Base: Integrating Physical Confinement and Chemisorption for Enhanced NO x Capture

Abstract Nitrogen oxides (NOx) demand urgent capture—they can trigger self-catalytic decomposition in nitrocellulose, risking combustion or explosion under high temperature and humidity. To counteract this, rigid, nonplanar building blocks with aliphatic C–H units, contorted Trög...

Learning to Self‐Interfere: Zero‐Shot Deconvolution Enables Replica‐Free, Low‐Coherence Common‐Path Quantitative Phase Microscopy

ABSTRACT Digital holographic microscopy (DHM) enables full‐field, label‐free, and high‐precision quantitative phase imaging (QPI), yet its performance is often limited by speckle noise, parasitic artifacts, and vibration sensitivity resulting from the highly coherent illumination...

Allosterically Controlled Capture of Mutually Repulsive Guests With Positive Cooperativity and Ultrahigh Affinity

ABSTRACT A hexacationic cage incorporating three urea units can encapsulate two mutually repulsive anions in close proximity through a combination of hydrogen bonding and electrostatic interactions. This leads to exceptionally high binding affinities, with a K 1 × K 2 value of ap...

Geosynthetic reinforcement and drainage in fine-grained embankments under rainfall

The increasing use of locally sourced fine-grained soils in embankment construction increases susceptibility to rainfall-induced instability due to low permeability, high water retention and limited shear strength. This study investigates the coupled reinforcement–drainage behavi...

Optimization of Multimodal Public Transit Networks Considering Spatial Equity

Public transport equity is usually assessed after a network has been designed rather than treated as a requirement that shapes the design itself. This study develops an equity-oriented optimization framework for hierarchical multimodal transit networks in which a fixed rail backb...
