Special Issue Information

Dear Colleagues,

For many years, Tribology has made tremendous progress in the understanding of the fundamental mechanisms that govern the phenomena which take place at the interface between contacting surfaces. Scientific efforts in both experimental and theoretical research allowed us an insight into these phenomena down to the molecular level, in most varied systems and in very different environments like for example biological, space, machine components, micro-electro-mechanical systems, and many others. All these advances offer areas of research and valuable tools to academics but the true gain is in applying them to practical situations; for this reason, the topic of this Special Issue is the “tribological design in real-life applicationsthe lubricant perspective”. The focus is thus on how various phenomena, which we associate with tribology such as for example friction, wear, corrosion, adhesion, the interaction between lubricant and solid surfaces influence the durability, reliability and functionality of systems. We will look at any application where tribological considerations influence the design focusing on the lubricant, the lubricant composition and its interaction with the solid surfaces. I invite researchers from both the industry and academia to contribute to this issue with either review or novel work that reveals the contribution of tribology to improving the design process in many fields.

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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Polyethylene terephthalate (PET), due to its excellent physical and chemical properties, has become a widely used packaging material for liquids across many consumer market segments. However, one of the most common problems met in bottle manufacturing is the pile-up of bottles during conveying, due to static electrification caused by localized friction. To minimize such phenomena, a thin lubricant layer is applied onto the bottles. The absence of a thin lubricant layer increases the risk of localized sticking phenomena and pileups. In this work, an attempt is made to study the frictional behavior of commercially available PET bottles, with and without lubrication by using a high precision and light load technique. By analyzing the complete tribological pattern of the tangential force and not just averaged values, localized sticking events can be identified. In addition, by performing indentation-retraction measurements the electrostatic forces in a bottle-to-bottle contact can be measured. By combining light load friction and adhesion methods, a better understanding of PET sticking phenomena can be achieved which then can be translated in optimizing (minimizing) the amount of lubricant to be used.
