Effect of Precipitated Particles on Corrosion Behavior of VCrFeTa0.1W0.1 and VCrFeTa0.2W0.2 Refractory High-Entropy Alloys

In this study, the influence of precipitated Laves particles on the metastable pitting of VCrFeTa0.1W0.1 and VCrFeTa0.2W0.2 refractory high-entropy alloys (HEAs) in 3.5 wt.% NaCl solution was investigated. Microstructures and corrosion behaviors were characterized by XRD, SEM, TE...

Weak or Strong Porter Effect? County-Level Evidence from China’s Prohibited Breeding Zone Policy in the Yangtze River Basin

The extent to which environmental regulation yields a “weak” or “strong” Porter effect is fundamentally shaped by the trade-off between industrial output and productivity improvements, a complex dynamic that requires granular, sub-national empirical evidence. This study employs a...

Corrosion behavior of Cr–Ni alloyed 690 MPa-grade high-strength weathering steel in simulated marine atmospheres

In this study, the corrosion behavior of Cr–Ni alloyed 690 MPa-grade weathering steel in simulated marine atmospheric environments was investigated in comparison with commercial E690 steel. After wet/dry cyclic corrosion testing, the corrosion resistance was quantitatively evalua...

Semantic composition and pragmatic reasoning in preschool children’s interpretation of negated gradable adjectives

Abstract Absolute gradable adjectives (e.g., dry ) and relative gradable adjectives (e.g., tall ) interact differently with negation, with only negated absolute gradable adjectives semantically entailing their antonyms (e.g., not dry ⊨ wet ). This study examined how 4- and 5-year...

Ergonomics-Aware Task Allocation for Human-Centric Collaborative Assembly: A Systematic Review

Human-centric manufacturing is reshaping collaborative production systems by repositioning human capabilities, safety, experience, and well-being as central concerns in the design and operation of intelligent manufacturing. As manufacturing moves toward Industry 5.0, task allocat...

A family of ultrathin non-van der waals kamiokite-type oxides for two-dimensional electronics

Non-van der Waals (vdW) two-dimensional (2D) metal oxides provide an opportunity to enrich the current 2D material library and accelerate the adoption of 2D materials into future electronic devices. However, the exploration of 2D non-vdW oxides remains limited, constrained by syn...

Corrosion life evaluation of organic/zinc composite coatings in water-saturated acid soil using electrochemical impedance spectroscopy

The corrosion behaviour and service life of organic/zinc composite coatings in water-saturated acid soil were investigated using electrochemical impedance spectroscopy (EIS) and open-circuit potential (OCP) measurements. For the duplex system, the service life of the organic topc...

Effect of Nickel Content and Cooling Rate on the Microstructure of As-Cast 316 Stainless Steels Part II: Ferrite and Precipitated Phases Under the Same Sampling Conditions

The presence of ferrite in 316 austenitic stainless steel affects its magnetic permeability, and the secondary precipitates formed by ferrite decomposition can further degrade the corrosion resistance, limiting its application in industries such as nuclear power and medical devic...

Occlusion Removal in Remote Sensing Images Based on Deep Matrix Completion

Remote sensing images are frequently degraded by occlusions and missing observations, which significantly affect subsequent interpretation and analysis. Matrix completion provides an effective solution for recovering incomplete data; however, existing deep learning-based approach...

Disuse enhances cancellous and cortical bone responses to mechanical loading by altering lacunocanalicular fluid dynamics

Disuse conditions, such as microgravity, prolonged bed rest, sedentary lifestyle, and limb immobilization, frequently affect human skeletal responses to mechanical loading. However, the precise impact of disuse on bone adaptation to mechanical loading and its underlying mechanobi...
