Boron nitride nanosheets filtration membrane for efficient separation of pollutant molecules from aqueous solution

Two dimensional nanomaterials have exhibit promising performance in membrane science, especially hexagonal boron nitride nanosheets (BNNSs) with inherent chemical inertness. Here, BNNSs membranes with compact and well-organized stacking texture were successfully prepared via vacu...

Linewidth narrowing in silver-coated fiber surface plasmon resonance sensors through waveguide-structure-dependent modal regulation

Broad resonance dips limit the spectral resolution and figure of merit (FOM) of wavelength-interrogated fiber surface plasmon resonance (SPR) sensors. Here, silver-coated no-core fiber (NCF), multimode fiber (MMF), and hollow-core fiber (HCF) probes were compared under matched se...

The Influence of Temperature and Clearance on the Tensile Properties of PC / GFRP Thermoplastic Composite Single‐Lap Bolted Joints

ABSTRACT Temperature and bolt–hole clearance significantly influence the mechanical performance of thermoplastic composite bolted joints. This study investigates single‐lap bolted joints made of PC/GFRP thermoplastic composites with plain‐weave (PW) and twill‐weave (TW) architect...

Non-monotonic cardiovascular adaptation and stroke output-stroke output coupling reorganization in high-altitude adolescents: a cross-sectional study along altitude gradients

Abstract Cardiovascular adaptation to chronic high-altitude exposure during adolescence remains incompletely understood because developmental autonomic regulation may differ from adult acclimatization. We examined whether cardiovascular responses vary non-monotonically across alt...

Disturbance observer-based predefined-time sliding mode attitude control for rigid spacecraft

This paper investigates the predefined-time attitude stabilization control of rigid spacecraft under external disturbances. A predefined-time stability criterion is established using a bounded function. A continuous predefined-time disturbance observer is designed to handle unkno...

Positively Charged Hollow Fiber Nanofiltration Membrane With an SPSf / PEI Bilayer Prepared via Dip‐Coating

ABSTRACT Nanofiltration (NF) has attracted considerable interest in water purification and resource recovery. Hollow fiber membranes offer high packing density, large surface‐area‐to‐volume ratio, and low‐pressure high‐flux operation. However, the fabrication of hollow fiber NF m...

A component-aware progressive transfer learning method for wind power forecasting in newly built wind farms

Accurate wind power forecasting is essential for wind farm operation and grid integration. However, newly built wind farms often have limited historical data, restricting the performance of data-driven models. Under data scarcity, conventional deep learning models tend to overfit...

Termination-Dependent Surface States and Magnetic Fingerprints of Chiral Helimagnet Cr1/3TaS2

Abstract Chiral helimagnets based on intercalated transition-metal dichalcogenides, characterized by nanoscale spin ordering, provide a powerful route to engineer chiral spin textures (e.g., the topologically protected magnetic solitons) and explore emergent electronic functional...

Solution-Processed Nanocomposite GO−AgNPs/AgNWs Transparent Conductive Films for Multifunctional Flexible Optoelectronics

Abstract As application scenarios and usage conditions become increasingly complex, traditional indium tin oxide materials are limited in meeting diverse application demands due to their low flexibility and high cost. This study proposed a ternary nanocomposite strategy combining...

Water-Triggered Pre-activation of Hydrogel Patch for Instant Robust Bioadhesion

Abstract Bioadhesives represent promising alternatives to sutures and staples for skin wound repair; however, existing systems are often limited by complex fabrication processes, poor adhesion under wet conditions, insufficient mechanical strength, and biocompatibility concerns....

Propagation of Chaos and Stability for the Nonlinear McKean-Vlasov Stochastic Functional Differential Equations with Common Noise

Abstract. Past dependence is an unavoidable natural phenomenon for dynamic systems. This paper investigates a class of nonlinear McKean–Vlasov stochastic functional differential equations (MV-SFDEs) with common noise. The well-posedness of the nonlinear MV-SFDEs with common noise...
