Tribology is the study of interactions between surfaces or interfaces in relative motion
(“tribos” means “to rub” in Greek). It includes the phenomena of friction, adhesion, and wear …

Macroscopic laws of friction do not generally apply to nanoscale contacts. Although
continuum mechanics models have been predicted to break down at the nanoscale, they …

We review the historical and modern understanding of the most basic equation of friction,
Amontons' law, which describes phenomena that were already understood and studied by …

In this chapter, we describe the static and dynamic normal forces that occur between
surfaces in vacuum or liquids and the different modes of friction that can be observed …

We show that the friction force varies with the sliding velocity in a manner that depends on
the chemical nature of the interface. Surfaces terminated with the hydrogen acceptor and …

Friction is a major issue in both the production of textiles and in the finished product. This
authoritative book reviews how friction occurs and the ways it can be measured and …

The materials properties of graphene and other two‐dimensional atomic sheets are
influenced by atomic‐scale defects, mechanical deformation, and microstructures. Thus, for …

Large-scale molecular-dynamics simulations are performed to study friction in nanoscale
single asperity contacts. The modeling system consists of a tip made of H-terminated …

Surfactants play a variety of critical roles in tribology. In addition to controlling friction and
wear, they also allow for control of a wide range of properties of lubricants, such as …

The friction of methyl-branched fatty acids was studied with a surface forces apparatus (SFA)
with attachments for low-speed (μm/s) and high-speed (cm/s) sliding. The systems studied …
