Calculations of the impact of friction and wear on energy consumption, economic
expenditure, and CO 2 emissions are presented on a global scale. This impact study covers …

Over the recent decades there has been tremendous progress in understanding and
controlling friction between surfaces in relative motion. However the complex nature of the …

Zinc dialkyldithiophosphate additives are used to control wear and inhibit oxidation in almost
all engine oils as well as many other types of lubricant. They limit wear primarily by forming a …

Zinc dialkyldithiophosphates (ZDDPs) form antiwear tribofilms at sliding interfaces and are
widely used as additives in automotive lubricants. The mechanisms governing the tribofilm …

Under the high-contact-pressure and shear conditions of tribological interfaces lubricated by
gaseous, liquid, and solid forms of carbon precursors, a variety of highly favorable …

Friction and wear reduction by diamond-like carbon (DLC) in automotive applications can be
affected by zinc-dialkyldithiophosphate (ZDDP), which is widely used in engine oils. Our …

Nonequilibrium molecular dynamics (NEMD) simulations have provided unique insights into
the nanoscale behaviour of lubricants under shear. This review discusses the early history of …

We provide a brief overview of the first techniques for direct, real-time observation of
mechanochemical reactions by milling. Whereas mechanisms and kinetics of solid-state …

This review article summarizes the progress of research on carbon nanomaterial-based
lubricants witnessed in recent years. Carbon nanomaterials, such as graphene, carbon …

CeO2 nanoparticles are potential anti-wear additives because of their outstanding anti-wear
and load-bearing capacity. However, the shear-sintering tribo-film formation mechanism of …
