Special Issue Information
Dear Colleagues,
With the continuous promotion of green, low-carbon, and circular-development economic systems, energy conservation, environmental protection, low carbon usage, and efficiency have become new requirements that various industries must meet in the development process, and the lubricant industry is no exception. At present, the main formula for lubricants is still dominated by mineral oil, and a very large amount of mineral oil is leaked or discharged into the environment. However, the biodegradability of mineral oil lubricants is poor. When they scatter to the ground or enter water, they will gradually accumulate and form non-degradable hydrocarbons, directly polluting soil and water. Moreover, waste mineral oil contains volatile organic pollutants, such as benzene series and polycyclic aromatic hydrocarbons, as well as a small amount of heavy metals, which pose great harm to the ecological environment and to human health.
Biolubricants offer new hope in terms of the sustainable development of human society. Biolubricants are generally considered to be lubricants made from base oils derived from vegetable oils or derivatives of vegetable oils. To protect the environment and develop their economy, many countries have put "Lubricants and Environmental Issues" on the agenda, formulated environmental protection regulations, put forward clear protection requirements, and committed to pursuing developments in, and research on, biolubricants. Biolubricants can meet the requirements of various industries for lubricant use without causing harm to human health or the environment. However, the synthesis and preparation mechanisms, anti-wear and friction reduction mechanisms, and tribological properties of biological lubricants, as well as the impacts of the actual application conditions on lubrication performance, are still unclear, resulting in a lack of scientific theoretical support for the application of biolubricants. Therefore, this Special Issue aims to introduce the latest developments in biolubricants and reveal the mechanism by which biolubricants improve anti-friction and wear reduction performance.

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.
