The need for energy efficiency is leading to the growing use of additives that reduce friction
in thin film boundary and mixed lubrication conditions. Several classes of such friction …

Friction is undoubtedly one of the most common yet intriguing physical phenomena
encountered in our daily lives. It would be impossible to play a stringed instrument or write …

Ultrathin graphene (UG) has been prepared by exfoliation of graphite oxide by a novel
technique based on focused solar radiation. Graphene based engine oil nanofluids have …

As the size of electronic and mechanical devices shrinks to the nanometre regime,
performance begins to be dominated by surface forces. For example, friction, wear and …

The cyclic polymer topology strongly alters the interfacial, physico‐chemical properties of
polymer brushes, when compared to the linear counterparts. In this study, we especially …

In present work, a superlubricity phenomenon of phosphoric acid (H3PO4) was found under
ambient conditions. An ultralow friction coefficient of about 0.004 between glass/Si3N4 and …

A complete understanding of the mechanism of boundary lubrication is a goal that scientists
have been striving to achieve over the past century. Although this complicated process has …

The lubrication of synovial joints is extremely efficient, allowing smooth motion to be
performed between relatively soft and vulnerable cartilage surfaces for close to 100 years. A …

The lubrication mechanism of concentrated polymer brushes (CPBs) exhibiting ultralow
frictional property was investigated. The frictional force and hence the frictional coefficient μ …

Poly (l-lysine)-graft-dextran (PLL-g-dex), graft copolymers with dextran side chains grafted
onto a poly (l-lysine) backbone, previously shown to be effective as stabilizers of DNA triple …
