“…As shown previously, DES have been used in a myriad of research fields, with diverse types of applications in mind, such as electrochemistry (Enrica et al, 2021), environmental chemistry (Malolan et al, 2021;Chen et al, 2021), and use as solvents , biosensors (Svigelj et al, 2021), and lubricants (Donato et al, 2021), among others, with an emphasis on the study of their physico-chemical properties (Aroso et al, 2017;Paiva et al, 2014). However, this manuscript focuses on their use as a solvent for the extraction of versatile bioactive compounds (Kalyniukova et al, 2021), highlighting the use of these extracts for cosmetic products.…”

“…Different approaches can be pursued to optimize and tailor the tribological response of a system. In this regard, lubrication strategies based upon new lubricants such as water [28][29][30] or ionic liquids [31,32], tailored additives [33][34][35] or even solid lubrication [36][37][38][39] are subject of ongoing research activities. Moreover, the deposition of low shear-strength coatings, particularly by physical or chemical vapor deposition [40], has been proven to be an efficient way to control friction and wear.…”

Surface textures with micro-scale feature dimensions still hold great potential to enhance the frictional performance of tribological systems. Apart from the ability of surface texturing to reduce friction, surface textures can also be used to intentionally increase friction in various applications that rely on friction for their adequate functioning. Therefore, this review aims at presenting the state-of-the-art regarding textured surfaces for high-friction purposes. After a brief general introduction, the recent trends and future paths in laser surface texturing are summarized. Then, the potential of surface textures to increase friction in different applications including adhesion, movement transmission and control, biomimetic applications, and road-tire contacts is critically discussed. Special emphasis in this section is laid on the involved mechanisms responsible for friction increase. Finally, current short-comings and future research directions are pointed out thus emphasizing the great potential of (laser-based) surface texturing methods for innovations in modern surface engineering.

Deep eutectic solvents (DES) are room-temperature liquid mixtures constituted of a hydrogen-bonding acceptor (HBA) and a hydrogen-bonding donor (HBD). They have high practical potential due to their versatility, quick preparation, and wide applications. Therefore, it is appropriate to have robust models to predict their properties. In this work, the density gradient theory has been combined with the perturbed-chain statistical associating fluid theory to model and understand the interfacial behavior in systems of deep eutectic solvents. DESs were modeled as mixtures of their constituents, and a methodology is proposed for estimating the chemical potential of DESs to extend their study to the interfacial properties. Available experimental data of hydrophilic and hydrophobic DESs were used to calculate the influence parameters, providing a way to linearize them in terms of the molecular parameters of HBDs and their molar ratio between HBD and HBA. This treatment has made it feasible to predict the thermal dependence of surface tension in most of the DESs analyzed with an average absolute relative deviation of 1.26%. Furthermore, density gradient theory and perturbed-chain statistical associating fluid theory were applied to predict the vapor−liquid surface tension in mixtures of organic compounds with DES. In particular, we have calculated the surface tension in mixtures of ChCl-glycerol and ChCl-lactic acid with water, ethanol, propanol, phenol, acetone, and ethyl acetate without fitting binary interaction parameters. The behavior of density profiles suggests that the surface is enriched with DES components for the DES + water mixtures. In contrast, it is enriched with diluent for the other ternary systems (ethanol, isopropanol, phenol, acetone, and ethyl acetate).
