While adsorption and lubrication properties of amphiphilic copolymers such as F-127 at a hydrophobic surface in aqueous media have been well established, its efficacy in serum can be more complicated due to potential interaction of F-127 with serum proteins or competitive adsorption onto UHMWPE surface. When an aliquot of F-127 solution (in concentration range of F-127 from 0.1% to 20% dissolved in 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES)) was added into serum where a CoCrMo pin is sliding against a UHMWPE disk, an immediate decrease in the coefficient of friction (COF) (ca. 20%) was observed. A spectroscopy study employing dynamic light scattering (DLS), circular dichroism (CD) spectroscopy, and ultraviolet (UV) absorbance spectroscopy has shown that serum associatively interacts with F-127 when the F-127 concentration is above critical micelle concentration (CMC), leading to an increase in hydrodynamic size and alteration of tertiary structure of proteins in serum. Mixing of F-127 with the solutions of selected single component biomolecules of serum showed that γ-globulin is the primary molecule that interacts with F-127 above CMC, followed by albumin. Meanwhile, no indication of interaction was observed when the F-127 concentration was below CMC. It is thus proposed that the observed lubricating effect of F-127 in serum is primarily due to the faster surface adsorption kinetics for its smaller molecular weight compared to serum proteins. Further, comparable % reduction in COF over a wide range of F-127 concentration indicates that unimeric F-127 molecules are dominant in contribution to friction-lowering effect even at above CMC at CoCrMo/UHMWPE interface in serum.

Although their excellent properties have been preliminarily confirmed, the mechanisms by which these properties influence performance—including fluid dynamics, electromagnetism, and chemistry—require systematic investigation. This paper addresses this gap by systematically reviewing the preparation, physicochemical properties, and potential applications of magnetic lubricants. First, the formulations of magnetic lubricants, including the base fluid and stabilizing additives, are thoroughly examined, considering various magnetic materials and preparation methods to elucidate the mechanisms influencing dispersion stability and magnetic response. Next, the physical properties, such as saturation magnetization, viscosity, and flowability, are analyzed through theoretical and experimental studies, and constitutive models for the fluid dynamics of magnetic lubricants are summarized. Furthermore, the advanced tribological and thermal properties, as well as the physical behavior under magnetic fields, are discussed, highlighting the superior antifriction, antiwear, cooling, and controlled flowability performance compared to traditional lubricants. Finally, current applications and potential fields, such as bearings, machining, and heat exchangers, are reviewed. This paper provides a valuable reference for both theoretical studies and engineering applications of magnetic lubricants.

In this paper, we first prepared a series of hydrogels crosslinked by ferric ion (Fe3+) through photoinitiated radical polymerization, and then a rheometer was used to measure their performance in terms of reducing drag in flow fields containing the water-soluble aqueous glycerol solution and the water-insoluble dimethyl silicone oil (DSO). The results showed all the hydrogels considered in our experiments could reduce drag in both experimental liquid oils, where their crosslinking with Fe3+ led to the decline of drag reduction. The higher viscosity of the aqueous glycerol solution induced a higher reduction in drag until it reached a value of 18 mPa·s. The hydrogels exhibited different mechanisms of drag reduction in different liquids. Drag reduction was induced in the aqueous glycerol solution by the boundary slip on the lubricating layer formed by the dissolution of water and glycerol, while that in DSO was induced by the boundary slip on the water layer of the surface of the hydrogel due to the insolubility of DSO in water. The work here revealed the mechanism of drag reduction induced by hydrogels that could be applied to marine transportation.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"38 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144097014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Guided by nature's evolutionary masterstrokes: the gecko's hierarchical fibrillar architecture enabling anisotropic van der Waals adhesion and the octopus' muscular-hydrodynamic suction synergies-researchers have engineered interfaces with unprecedented environmental adaptability. Despite breakthroughs in robotics and biomedicine, synthetic SAFMs persistently lag biological counterparts in three dimensions: structural hierarchy fidelity, dynamic stability under cross-media disturbance, and adaptability to concurrent multi-environmental. Through a comparative analysis of biotic/abiotic mechanisms, we demonstrate how current state-of-the-art synthetic systems, often limited by single-environment optimization or manufacturing-compromised structural hierarchies, fail to match the robustness of natural systems. To overcome these barriers, we propose a co-design framework integrating: multiple mechanism synergy, multiple functional material networks, and bio-inspired fabrication technologies. By bridging these domains, the framework aims to realize multiple environmental adaptive bio-inspired adhesion/friction that transcend current application silos from space environments tolerant robotic for lunar exploration to self-adjusting biomedicine devices for health monitoring.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"77 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144088205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multilevel structure on the peristome surface of Nepenthes alata creates a stable liquid film and long-term slippery phenomena, providing excellent antisticking performance. However, transferring the multilevel structure to metallic substrates is a critical challenge. Herein, a facile method using a bionic replication process combined with an electroforming process was reported to successfully prepare a realistic metallic-peristome surface (MPS) from the peristome surface of Nepenthes alata to a copper-based substrate. The long-term lubrication theory of MPS was analyzed, which demonstrated the high wettability and robustness of the surface. The unidirectional transport behavior and long-term lubrication performance of dimethyl silicone oil on the MPS under the action of a thermal field gradient were analyzed. The results show that the as-prepared metallic-peristome surface has liquid transport capability in the opposite direction of the thermal field gradient. In addition, the introduction of microstructures on the surface of the MPS electrode can promote the occurrence of spark effects and improve the cutting effect. An electrocution test of isolated pig liver tissue was conducted to test the tissue antisticking properties, thermal damage, and antibacterial effects of self-lubricating slippery surface bionic electrosurgery. MPS exhibits excellent antistick properties, low thermal damage, and significant antibacterial properties, laying the foundation for its application in other fields.

This review synthesizes current research on wear modeling and friction-induced noise, exploring their mechanisms, influencing factors, and predictive challenges. Wear modeling encompasses a range of approaches, from traditional methods such as the Archard equation to more advanced numerical and machine learning techniques. These models address diverse mechanisms—adhesive, abrasive, and fatigue wear—which are shaped by material properties, surface roughness, and environmental conditions. Friction-induced noise, arising from stick-slip, sprag-slip, and mode-coupling, is influenced by surface states, damping, and operational parameters. Crucially, wear and noise are interlinked. Wear reshapes surfaces and dynamics, thereby modulating noise, while noise can serve as a diagnostic tool for wear progression. Yet, existing models often isolate these phenomena, neglecting their synergy and impeding accurate system-life predictions. This review highlights this gap and advocates for the development of integrated wear-noise models, harnessing multiscale simulations, advanced computation, and empirical validation. The development of such models has the potential to significantly enhance the accuracy of durability and acoustic performance predictions. They offer a holistic framework that captures the dynamic interplay between surface degradation and noise generation. This framework is essential for advancing non-invasive detection technologies in industries such as automotive, aerospace, and manufacturing. In these sectors, addressing these dual challenges is crucial for enhancing performance, safety, and efficiency.","PeriodicalId":12442,"journal":{"name":"Friction","volume":"2 1","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143933222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
