As one increases the concentration of a colloidal suspension, the system exhibits a dramatic
increase in viscosity. Beyond a certain concentration, the system is said to be a colloidal …

This review provides an overview of recent advances that have been achieved in
understanding the basic physics of friction and energy dissipation in molecularly thin …

Ionic liquids have remarkable physico-chemical properties that make them highly attractive
as new solvents or electrolytes in applications ranging from solar cells to MEMS lubrication …

The behavior of water and other molecular liquids confined to the nanoscale is of
fundamental importance, eg, in biology, material science, nanofluidics, and tribology. Direct …

Water is ubiquitous in the environment and is the origin for operational constraints in ionic-
liquid based electrolytes for supercapacitors. In this study, the influence of water on the …

The rheological properties of liquids confined to nanometer scales are important in many
physical situations. In this Letter, we demonstrate that the long-range elastic deformation of …

The direct measurement of forces between atomically smooth mica surfaces down to sub-
nanometer separation was pioneered over 50 years ago and has yielded deep …

Lubricants with desirable frictional properties are important in achieving an energy-saving
society. Lubricants at the interfaces of mechanical components are confined under high …

The dynamics of fluid flow at the interface between elastic solids with rough surfaces
depends sensitively on the area of real contact, in particular close to the percolation …

Harnessing the subsurface geologic environments in an efficient and environmentally
sustainable manner is challenged by uncertainties associated with predicting the fate of …
