Special Issue Information

Dear Colleagues,

The traditional role of lubricants was to protect and increase the service life of mechanisms, devices and components. Today customer-designed lubricants must take into account environmental, health and energy consumption issues.
Scientists and engineers now dispose of a battery of surface and chemical analysis tools which enable them to try to comprehend the micro- and nanomechanisms operating at the sliding contacts, including lubricant-surface interactions, tribochemistry and tribocorrosion processes. The new advances in synthesis and instrumentation have open the era of nanomaterials and nanolubricants, where solid nanophases or lubricant dispersed nanophases are used as lubricants.
Additives are materials or molecules that improve the performance of lubricants. Advances have been recently made on the use of so-called ‘ordered fluids’, such as mesophases and room temperature ionic liquids both as neat lubricants and lubricant additives.
From the materials point of view, effective lubrication of light alloys and some polymers remains a challenge. Finally, lubrication under extreme conditions such as high temperature, cryogenic conditions or high vacuum is a determining technology for advanced industrial and aerospace applications.
This special issue on Lubricants should cover the present moment and future developments in the field lubricant development and application.

We synthesized the novel nanocomposite consisting of alternately stacked single graphene sheets and a C60 monolayer by using the graphite intercalation technique in which alkylamine molecules help intercalate large C60 molecules into the graphite. It is found that the intercalated C60 molecules can rotate in between single graphene sheets by using 13C NMR measurements. The grease with the nanocomposite materials provides a much better lubricating performance than that with other additives that have been well-known up to now. This result exhibits that a C60 monolayer intercalated between graphenes plays an important role in lubricating behavior. Full article
