Reynolds equation is a partial differential equation that describes the flow of a thin lubricant film between two surfaces. It is derived from the Navier-Stokes equations and is one of the fundamental equations of the […]

Guidance Notes on Friction

19.03.2018

In dry sliding between a given pair of materials under steady conditions, the coefficient of friction may be almost constant. This is the basis for two EMPIRICAL Laws of Sliding Friction, which are often known [...]
Molecular Dynamic Simulations and AFM Experiments at Overlapping Speeds

11.04.2016

Atomic Force Microscopy (AFM) is a powerful and convenient experimental measurement device in the field of nano-scale tribology. It was successfully applied to explore superlubricity in a graphene-gold interface and superlubricity due to repulsive van [...]
Detect stress and fracture using color changing elastomers - mechanochromic sensors

16.04.2018

Biological materials have complex mechanical properties that are difficult to reproduce using synthetic materials. An international team of researchers, including Dr. Andrey Dobrynin, a professor in The University of Akron’s College of Polymer Science and [...]
Leonardo da Vinci as a Tribologist

10.06.2019

Tribology is the science dealing with interactive surfaces in relative motion and includes the study of friction, wear, and lubrication and how these properties affect design. The term tribology was coined in 1966 by Peter [...]
The ‘Origami Robot’ that can be ingested

19.10.2017

Ever swallowed a button-battery? And wondered how to get it out? Have no fear, the origami robot is here! That’s right, the Massachusetts Institute of Technology (MIT) has come up with a pill-sized origami robot, which will [...]
