In recent decades, lubrication science has increasingly focused on multi-scale phenomena with the specific aim to correlate what occurs at the micro-scale with the global tribological performance at the macro-scale. Massive research efforts on theoretical significance and engineering interest have occurred in this regard. However, our knowledge of multi-scale lubrication is still far from complete. Specifically, in spite of many analytical, numerical and experimental approaches, an exhaustive description of the role played by the micro-topography of the contacting solids in determining the lubrication performance is still missing. The so-called boundary and mixed lubrication regimes, which are crucially important for applicative and engineering reasons, are indeed marked by a poor theoretical knowledge.
This Special Issue aims to promote advances in this field, in particular, the role played by the roughness in lubrication. We invite authors to submit original research and review articles that will stimulate continuing effort to understand and improve our understanding of multiscale lubrication. We are particularly interested in contributions focusing on lubrication of macro-, micro-, and nano-systems. Potential topics include, but are not limited to the following:
- Molecular Dynamics (MD) simulation;
- Stochastic and/or deterministic solution of Reynolds equations for boundary and mixed lubrication;
- Complementary approaches and the role of cavitation at the micro-scale;
- The roles of slip length and hydrophobicity at the micro- and meso-scale;
- Topographical micro-design in boundary and mixed lubrication;
- The roles of lubricant and solid rheology in multi-scale lubrication;
- Experimental characterization of tribological performance by means of innovative micro- and nano- tribometers; and
- Experimental innovative tribo-experiments (e.g., ultrasonic, fluorescence techniques).

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Lubricants is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
