Special Issue Information
Dear Colleagues,
Thermocapillary migration is a very intriguing phenomenon, in which the variation in the surface tension of a liquid is affected such that the liquid is driven from low-tension regions to high-tension regions. This implies that a thermal gradient, which might occur on rubbing surfaces due to frictional heating, can induce a movement of liquid lubricants from a high-temperature region to a low-temperature region. This kind of migration is of central importance to many tribological applications. In some applications, such as mechanical seals, one may desire that the lubricant migrates in a predetermined direction induced by a temperature difference. In others, lubricant migration may need to be minimized to ensure that adequate lubrication is present where it is needed. Clearly, this concept has numerous applications in machinery from engines to compressors to mixers and in vital mechanical components, such as piston rings, bearings, hard disk, and so on. Investigation on the design, preparation, and thermocapillary migration behavior of lubricating materials are of vital importance for modern tribology systems.
In particular, the topic of interest includes but is not limited to:
- Anti-migration coatings;
- Migration barrier films;
- Liquid and solid lubricants;
- Fundamental lubrication at surfaces and interfaces;
- Surface texturing;
- Surface properties and characterization;
- Micro/nano functional surfaces;
- Fundamental and functional properties of surfaces and interfaces;
- Tribology heat and mass transfer;
- Fluid film lubrication;
- Hydrodynamic lubrication;
- Theoretical and computational modeling of lubricant migration.
In this Special Issue, original research articles, reviews, short notes, or communication are welcome.
We look forward to receiving your contributions.

Manuscript Submission Information
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. Coatings 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.
Benefits of Publishing in a Special Issue
