“…The tribological performance under dry conditions can be notably improved by the combined use of surface textures and solid lubricants, [8] which is also a promising avenue to be explored for MXenes. [138] Initial studies combining grooves [139] or bionic cross-like textures [140] and MXenes (ml-Ti 3 C 2 T x [139] and NbC 2 T x [140] ) have shown beneficial effects with potential for further improvements. However, the studied systems are rather complex and difficult to analyze due to the usage of MXenes, surface textures, and self-lubricating Sn-Ag-Cu alloys.…”

efficiency, the significance of tribology becomes evident in light of global challenges such as decreasing earth resources, i.e., fossil fuel and minerals, as well as steadily rising CO 2 emissions contributing to global warming. [4,5] In this context, friction and wear have been identified as notably contributing toward a downgraded energy efficiency, inviting the development of greener, smarter, and more sustainable tribological processes and lubricants.Since ancient times, the most straightforward approach to reduce friction and wear was to place a liquid lubricant (oil or grease) between the rubbing surfaces. This greatly reduces or eliminates the solid-solid contact, thus enabling low-friction and lowwear conditions. [6] However, after centuries of use, liquid lubricants have been pushed toward their limits due to the current trend of continuously reducing the lubricant viscosity and, therefore, the resulting film thickness. This, in turn, increases the amount of solid-solid contact, leading to harsher tribological conditions with increased friction and wear. Combined with more stringent regulations regarding the use of sulfur-and phosphorous-containing lubricant additives as well as efforts toward decarbonization to reduce CO 2 emissions and hazardous wastes, these factors propel the urgent development of alternative lubrication concepts. [4] In this context, nanomaterials used as additives in base oils or applied as solid lubricant coatings have gained notableThe large and rapidly growing family of 2D early transition metal carbides, nitrides, and carbonitrides (MXenes) raises significant interest in the materials science and chemistry of materials communities. Discovered a little more than a decade ago, MXenes have already demonstrated outstanding potential in various applications ranging from energy storage to biology and medicine. The past two years have witnessed increased experimental and theoretical efforts toward studying MXenes' mechanical and tribological properties when used as lubricant additives, reinforcement phases in composites, or solid lubricant coatings. Although research on the understanding of the friction and wear performance of MXenes under dry and lubricated conditions is still in its early stages, it has experienced rapid growth due to the excellent mechanical properties and chemical reactivities offered by MXenes that make them adaptable to being combined with other materials, thus boosting their tribological performance. In this perspective, the most promising results in the area of MXene tribology are summarized, future important problems to be pursued further are outlined, and methodological recommendations that could be useful for experts as well as newcomers to MXenes research, in particular, to the emerging area of MXene tribology, are provided.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adma.202207757.

“…The other aspect is suppressing tool wear by introducing micro-nano textures on diamond cutting tool. The presence of surface micro-textures on diamond tool can produce predominant functionalities compared with untextured tools [82][83][84][85][86]. In the field of diamond cutting, the retention and accessibility of lubricant can be improved by the reasonable micro-texture design on diamond tool surface, thus reducing the machining force, the cutting temperature and the tool-chip interface friction [87].…”

Ultra-precision diamond cutting is a promising machining technique for realizing ultra-smooth surface of different kinds of materials. While fundamental understanding of the impact of workpiece material properties on cutting mechanisms is crucial for promoting the capability of the machining technique, numerical simulation methods at different length and time scales act as important supplements to experimental investigations. In this work, we present a compact review on recent advancements in the numerical simulations of material-oriented diamond cutting, in which representative machining phenomena are systematically summarized and discussed by multiscale simulations such as molecular dynamics simulation and finite element simulation: the anisotropy cutting behavior of polycrystalline material, the thermos-mechanical coupling tool-chip friction states, the synergetic cutting responses of individual phase in composite materials, and the impact of various external energetic fields on cutting processes. In particular, the novel physics-based numerical models, which involve the high precision constitutive law associated with heterogeneous deformation behavior, the thermo-mechanical coupling algorithm associated with tool-chip friction, the configurations of individual phases in line with real microstructural characteristics of composite materials, and the integration of external energetic fields into cutting models, are highlighted. Finally, insights into the future development of advanced numerical simulation techniques for diamond cutting of advanced structured materials are also provided. The aspects reported in this review present guidelines for the numerical simulations of ultra-precision mechanical machining responses for a variety of materials.

“…On the other hand, orthodontic wax materials have been normally approved as extraordinary lubricants for minimising the friction forces of the archwire-bracket contact combinations in the clinical orthodontic treatment. Therefore, according to the various challenging and successful strategies of combining surface texturing and solid lubricants (e.g., coatings) for tailoring the friction and wear performance of the engineering surfaces, [45][46][47] the potential synergistic effects of the micro-grooves texture together with the orthodontic wax materials for obtaining a low friction coefficient and a low wear of the archwire-bracket sliding contacts in artificial saliva environment were further studied.…”

Minimising the friction force of the archwire‐bracket sliding contact is crucial for achieving a high‐quality orthodontic treatment. Micro‐dimples and micro‐grooves textures were successfully produced on the two slot surfaces of the stainless steel orthodontic brackets with the laser surface texturing technology. The effect of surface texture on reducing the friction and wear behaviour of the stainless steel archwire‐bracket sliding contact combinations in artificial saliva environment was investigated. Friction coefficients of less than 0.15 and mild wear were obtained by using the three rows micro‐grooves textured bracket with a width of 60 μm and a spacing of 150 μm. The friction and wear performance was further enhanced with the addition of orthodontic wax materials. It was strongly argued that the synergetic effects of the fabricated micro‐grooves texture and the added orthodontic wax materials leading to the outstanding friction and wear behaviour of the archwire‐bracket sliding contacts.
