The challenge of the complex oxygen evolution reaction (OER) currently impedes the efficient production of hydrogen via electrolytic water splitting. To address this issue, the development and improvement of effective electrocatalysts are required. LiCoO2, a key material in lithium-ion batteries, has shown promising potential as an electrocatalyst for electrochemical energy conversion. However, OER catalysts derived from LiCoO2 have faced obstacles such as high overpotential and a complicated preparation process. In this study, the preparation method is adjusted to optimize the synthesis of Li1-xCoO2 with a defective structure, resulting in an impressive overpotential of only 290 mV at a current density of 100 mA cm−2 and a remarkable Tafel slope of 15.2 mV dec−1. The exceptional catalytic activity of Li1-xCoO2 can be attributed to the absence of Li, which triggers oxidative alterations in the electronic structure of Co. Density functional theory (DFT) calculations reveal that Li defects can influence the d-band center of active Co sites, enhancing the adsorption capabilities of Co sites towards *OOH intermediates and increasing the conductivity of the electrocatalyst during the OER process. These alterations improve the velocity of the crucial step in the reaction, ultimately boosting the catalyst's overall performance and efficiency. © 2024 The Authors

Mussel inspired polydopamine (PDA) has been extensively applied as a linker in noble metal based heterogeneous catalysts to promote either metal dispersion or metal-support interaction. Herein, three heterogeneous Pt catalysts were first prepared by depositing Pt on PDA encapsulated porous silica (SiO2-PDA-Pt) with different PDA coating degree and their catalytic activity toward two model hydrosilylation reactions between methyldichlorosilane and a non-polar 1-octene and a polar allyl cyanide were investigated. Meanwhile, stability and recyclability of these catalysts were also explored. Results show that PDA coating degree may directly influence both Pt loading and its oxidation state, which then resultantly tailor the activity of the supported catalysts. The SiO2-PDA-Pt catalysts all showed excellent activity even after six catalytic rounds even though a gradual loss of Pt species were observed. Among them, the activity of the one with lowest PDA coating exhibited both higher activity and better recyclability, which is mainly ascribed to a higher content and retention of more active low valent Pt0 species that may be well stabilized by proper PDA coating. © 2025 Elsevier B.V.

Traditional method for evaluating the coefficient of friction (COF) of laser cladding high-entropy alloy (HEA) coatings, relying on extensive experiments, is costly and inefficient. To address these limitations, this study proposed an efficient machine learning (ML) approach. Random Forest, Gradient Boosting Decision Tree, and XGBoost models were developed as base models to predict the COF of HEA coatings. Feature engineering and a voting strategy were employed to enhance model accuracy and generalization ability, yielding substantial improvements in performance. The optimal model achieved a testing R 2 of 0.97. A satisfactory agreement was achieved between the predicted COFs and the experimental measurements as well as their trend. Additionally, the impact of each feature on the COF was clarified using SHAP (Shapley Additive Explanations). The results indicate that this ML approach is a promising tool for predicting the COF of HEA coatings and can serve as a valuable aid in the design and optimization of coatings.

LWT 2025年 224卷

作者： Zu, Xiaoyan Guo, Lu Zhou, Zhi Xiong, Guangquan Peng, Lijun Liu, Qi Fu, Jianlong Wang, Yi Guo, Peng Li, Hailan Hubei Academy of Agricultural Sciences Wuhan430064 China School of Biological and Food Engineering Hubei Minzu University Enshi445000 China Agro-product Processing Research Sub-center of Hubei Innovation Center of Agriculture Science and Technology 430064 China School of Resources and Environmental Engineering Wuhan University of Technology Hubei Wuhan430070 China

To assess the feasibility of developing fish scale peptides as melanin inhibitors, peptides were extracted from the scales of silver carp (Hypophthalmichthys molitrix). By performing selenocysteine modification, molecular docking, and in vitro analyses, it was identified SGP-C(Se) as the peptide with the strongest antioxidant activity. Further studies included tyrosinase (TYR) inhibition assays, ultrafast kinetic analysis, and validation experiments using B16 melanoma cells. The results revealed that SGP-C(Se) (2 mM) had a strong antioxidant activity, with ·OH and DPPH· radical scavenging rates reaching 98.20 % and 97.66 %, respectively, and at the same concentration induced 99.27 % tyrosinase inhibition. In molecular dynamics, the SGP-C (Se)-TYR system was stable, and its fluorescence lifetime (τ1 = 4.40 ns) was shorter than that of SGP-C (Se) (τ2 = 5.54 ns) and TYR (τ3 = 8.00 ns). At 0.5 mM, SGP-C(Se) significantly reduced the levels of reactive oxygen species and cAMP in B16 cells, down-regulated the expression of proteins associated with the Wnt/β-catenin, cAMP-CREB, and MAPK signalling pathways, and suppressed the mRNA transcription of MITF, TYR, TRP-1, and TRP-2. These findings highlight the potential of SGP-C(Se) as a melanin inhibitor for biological applications. © 2025 The Authors

In this study, the changes in functional properties and binding mechanisms at the molecular level of a non-covalent complex formed between sweet potato leaf polyphenols (SPLPs) and rice bran albumin (RBA) were investigated. Multi-spectral analysis indicated that SPLPs statically quenched the intrinsic fluorescence of RBA, and fitting to a double logarithmic equation revealed that hydrogen bonding constituted the primary driving force behind this interaction. Consequently, the conformational structure, microenvironment, and surface hydrophobicity of RBA were significantly impacted. With 7 μmol/L of SPLPs added to RBA, the emulsifying activity and stability of the complexes were enhanced by 45.71 % and 392.30 %, respectively, compared to RBA. Similarly, the thermal stability of 3,5-diCQA was enhanced by 176.29 %, alongside an improved ultraviolet tolerance. Molecular docking and molecular dynamics simulations clarified that the A0A191ANP5, B8AHL6 and P52428 subunit in RBA has a stronger affinity with the most abundant polyphenols in SPLPs, which was the 3,5-disubstituted caffeoylquinic acid (3,5-diCQA). These findings may furnish a theoretical foundation for the prospective utilization of SPLPs and RBA complex products as functional food ingredients. © 2025 Elsevier B.V.

Yam is consumable subterranean rhizomes or tubers, derived from plant sources in the Dioscorea genus. More than 90 of the roughly 600 yam species found in the world are found in East Asia. Additionally, yam contains bioactive compounds, which are non-nutritive components with vital health benefits, including phenolic compounds, saponins, tannins, and flavonoids, which contribute to its diverse therapeutic potential. Despite the numerous benefits inherent in yams, they also offer huge healthy perks, like antioxidants, anti-inflammatory, hypoglycemic, antimicrobial, and anti-tumor outcomes, making them important food candidates in the nutraceutical and pharma sectors. This review synthesizes current knowledge on nutritional composition, bioactive properties, extraction methods, therapeutic potentials, biological properties and administration. Strategies to enhance its utilization for greater impact are also discussed. This review highlights the potential of yam as a functional food, emphasizing its role in promoting dietary diversity and contributing to the prevention and management of non-communicable diseases, while also exploring associated challenges, emerging applications, and future research directions.

Diamond-like carbon (DLC) serves as a prevalent protective coating for stainless steel in various applications, including automotive engines and medical devices, to combat wear and corrosion. This investigation delves into the nanoscale interface friction and mechanical behavior between DLC and polycrystalline austenitic stainless steel. Molecular dynamics simulations were employed to model the sliding interface structure's evolution and friction performance under differing contact pressures and graphitization states. In the friction sliding process, carbon atoms predominantly experience surface structural reorganization with minimal diffusion. The displacement of stainless steel's internal atoms is chiefly driven by deformation rather than diffusion. The study also examines the synergistic impacts of external pressure, structural transformations, and interfacial compounds on the system's friction mechanism. At low contact pressures (≤8 GPa), austenite deformation and recrystallization triggered by friction were noted. Conversely, at high junction pressures (>8 GPa), the interplay of stress and strain induces martensitic transformation in stainless steel and amplifies mechanical mixing with DLC. The α′-martensite proportion correlates positively with contact pressure and friction duration. An uptick in martensite content escalates the system's friction force;however, when the system's friction is governed entirely by martensite, it manifests a stable low friction force. Furthermore, under varied carbon atom hybridization conditions, systems characterized by high sp3 hybridization display increased strain and friction. These insights provide valuable perspectives for improving the research on DLC and stainless steel nano micro interfaces. © 2025

Preliminary studies have indicated that reducing the particle size of tea polysaccharides (TPS) significantly enhances their absorption, although this process also diminishes their antioxidant capacity. To effectively address this challenge, we have successfully synthesized highly stable selenium nanoparticles (SeNPs) using sodium selenite and ascorbic acid as reductants. TPS is an excellent stabilizer and dispersant. Comprehensive characterization through particle size analysis, transmission electron microscopy (TEM), UV-Vis spectroscopy, FT-IR, XRD, and XPS confirms that the resulting TPS-SeNPs exhibit a striking orange-red color, are amorphous, zero-valent, and spherical, with an average particle size of 82.2 nm. The binding of SeNPs to TPS via Se-O and Se-N bonds has been confirmed. Stability tests unequivocally demonstrate that TPS-SeNPs remain stable under various conditions. In vitro experiments reveal robust antioxidant activity, efficient selenium slow-release properties, and enhanced polysaccharide digestion, underscoring their significant potential as antioxidant supplements. © 2025, The Authors.
