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.

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.

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.

The multilevel structure on the peristome surface of <i>Nepenthes alata</i> 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 <i>Nepenthes alata</i> 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.

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.
