Summary: This study focuses on how plasma treatment can modify the surface of an AA 5052-H32 aluminum alloy, and investigates the effects of discharge power, exposure time, and working gas as process parameters on the adhesion between the aluminum alloy and GFRTP polycarbonate composite. The researchers analyzed the surface composition and morphology of the alloy using X-ray photoelectron spectroscopy and scanning electron microscopy, and evaluated surface roughness and wettability. The results showed that nitrogen plasma treatment significantly improved bonding strength due to both rough surface mechanical bonding and chemical bonding between the alloy and GFRTP, but the improvement in surface wettability diminished over time due to re-adsorption of hydrocarbon contamination.

Summary: This study investigates the influence of active particles on the atomization characteristics of aviation kerosene and explores the key technologies of plasma application in fuel atomization. The experiments were conducted to diagnose the spectrum of He plasma jet and analyze the fuel atomization characteristics. It was found that He plasma ionizes the surrounding air, producing active particles such as OH, O, and He I atoms. The electron excitation temperature varies with peak voltage and reaches its maximum at 11 kV. The electric field application and He volume flow rate have significant effects on the atomization characteristics, with increasing peak voltage resulting in decreased SMD and increased spray cone angle. The volume flow rate of He also affects the atomization, with higher flow rate leading to decreased SMD and increased spray cone angle. The difference in oil supply pressure also affects the atomization effect of plasma excited fuel.

Summary: This study investigates the surface properties of methyl-terminated organosilica films modified by atmospheric-pressure water vapor plasma. Plasma modification leads to an immediate decrease in water contact angle, as methyl groups are oxidized to form oxygen-containing groups. The films show a moderate hydrophobic recovery after certain treatment. The changes in surface hydrophilicity during long-term storage are attributed to the rotation of Si-OH.

Summary: Photocatalytic technology is a promising alternative for water treatments, but its practical application is limited by low efficiency and selectivity. In this study, two-dimensional zinc oxide nanosheets decorated with copper-palladium bimetallic nanoparticles were synthesized for the degradation of organic dyes in water. The prepared composites showed superior photocatalytic performance compared to pristine ZnO nanosheets under visible-light irradiation, attributed to enhanced separation and transfer efficiency of charge carriers. The highest catalytic efficiency was achieved by CuPd/ZnO nanocomposite with 0.5 wt% CuPd, achieving 95.3% removal of methyl orange within 45 minutes. This study provides a new avenue for the design and fabrication of high-performance photocatalysts for water treatments.

Summary: Recently, MXene-based wearable hydrogels have become promising candidates for epidermal sensors due to their softness and unique properties. However, it is challenging to achieve reliable sensing performance and prolonged service life due to MXene oxidation in water-containing hydrogels. To address this issue, catechol-functionalized poly(vinyl alcohol) (PVA-CA)-based hydrogels are proposed to inhibit MXene oxidation, resulting in rapid self-healing and superior strain sensing behaviors. The PVA-CA-MXene hydrogel demonstrates potential for real-time motion monitoring and accurate signal classification using deep learning models.

Summary: To increase the capacitance of an inorganic electrode material, CoFe-layered double hydroxide (LDH) was grafted onto the surface of hexagonal-flower-like NiCo2O4. Various composites with different Co/Fe ratios were grown directly on Ni foam using the hydrothermal method. The composite with a Co/Fe molar ratio of 1:2 (NiCo2O4 @Co1Fe2-LDH) exhibited the best electrochemical performance, with a specific capacitance of 2595 F g-1 at a current density of 1 A g-1. The composite prevented aggregation of CoFe-LDH, leading to high specific capacitance and good stability. The electrode was used in a packaging asymmetric capacitor, resulting in a maximum energy density of 27.33 Wh kg-1 at a power density of 800 W kg-1 and an excellent capacitive retention of 96% even after 5000 charge-discharge cycles.

Summary: The effects of Lc on the depth of the operative interphase, operative filler concentration, and mechanical percolation start are studied. An equation is proposed to determine the strength of HNT composites with an imperfect interphase and an HNT network. The relationships between B and Lc, HNT size, and percolation start are analyzed. The lowest Lc, lowest percolation start point, slimmest and longest HNTs, and highest interfacial shear strength yielded the highest B values and the toughest samples.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
