Salvia Miltiorrhiza, extensively distributed and commonly employed as a traditional Chinese medicinal herb, has garnered significant attention. In this study, the Miltiorrhiza extract (SME) was prepared by one-step water extraction method, firstly used novel corrosion inhibitor for Q235 steel in 1 mol/L HCl solution. As identified via liquid chromatography-mass spectrometry, findings reveal that Salvianic acid A, tanshinone II danshenxinkun D, dihydrotanshinone, methylene tanshinquinone are primary constituents of SME. The optimum inhibition efficiency reached 92.8 % at 200 mg/L maintained 90.4 after 72 h. Based on in-situ scanning vibration electrode technology (SVET) monitoring, adsorption molecules metal surface greatly retarded propagation localized corrosion. AFM examination corroded reveals samples supplemented with SME exhibit smoother compared to blank group. force curve graph SME-added group demonstrates more evenly point array an elevated average adhesion force, indicating addition improves resistance surface. XPS characterization illustrated interacted iron ions form insoluble precipitate. This work investigated application eco-friendly carbon acidic medium, providing new approach high value-added utilization Milliorrhiza.

Graphene-Enhanced Piezoelectric Nanogenerators for Efficient Energy Harvesting

C – Journal of Carbon Research, Год журнала: 2025, Номер 11(1), С. 3 - 3

Опубликована: Янв. 1, 2025

Graphene-based piezoelectric nanogenerators (PENGs) have emerged as a promising technology for sustainable energy harvesting, offering significant potential in powering next-generation electronic devices. This review explores the integration of graphene, highly conductive and mechanically robust two-dimensional (2D) material, with PENG to enhance their conversion efficiency. Graphene’s unique properties, including its exceptional electron mobility, high mechanical strength, flexibility, allow development superior performance compared conventional PENGs. When combined materials, polymers, graphene serves both an active layer charge transport medium, boosting response output power. The graphene-based PENGs can harvest from various sources, vibrations, human motion, ambient environmental forces, making them ideal applications wearable electronics, low-power paper provides overview fabrication techniques, material mechanisms PENGs, into real-world applications. findings demonstrate that incorporation enhances PENG, paving way future innovations energy-harvesting technologies.

Research on the Performance of a Liquid–Solid Triboelectric Nanogenerator Prototype Based on Multiphase Liquid

Micromachines, Год журнала: 2025, Номер 16(1), С. 78 - 78

Опубликована: Янв. 11, 2025

In recent years, liquid–solid triboelectric nanogenerators (L-S TENGs) have been rapidly developed in the field of liquid energy harvesting and self-powered sensing. This is due to a number advantages inherent technology, including low cost fabricated materials, structural diversity, high charge-energy conversion efficiency, environmental friendliness, wide range applications. As phase dielectric materials typically used L-S TENG, variety organic inorganic single-phase liquids, distilled water, acidic solutions, sodium chloride acetone, dimethyl sulfoxide, acetonitrile, as well paraffinic oils, experiments. However, it noteworthy that function multiphase liquids still understudied. The “Multiphase Liquid Triboelectric Nanogenerator Prototype (ML-TENG Pro)” presented this paper takes single-electrode solid–liquid nanogenerator basic model uses lubricating oil deionized water materials. After verifying stability (e.g., DI seawater, ethanol, etc.) for power generation, generation performances oil–water two-phase, gas–oil–water three-phase (with small bubbles), many bubbles) open space are further investigated. COMSOL Multiphysics 6.0 software was investigate material transport mechanism formation two-phase three-phase. Finally, study presents performance ML-TENG Pro extreme state “emulsification”. outlines limitations ML-TENG, named PRO, suggests avenues future improvement. research provides theoretical basis evaluating quality lubricants mechanical equipment.
