Plastic Deformation at Microscale

08.04.2020 Dr. Nilgoon Irani

What is plastic deformation? Plastic deformation, in general, can be defined as a permanent deformation, a non-reversible change in the geometry of a body under applied stresses (forces). For example, if hit sufficiently hard by […]

Macroscale superlubricity

Friction rises when bodies come to contact and start relative sliding. This phenomenon occurs in many mechanical systems and it is estimated that over 30% of the fuel in cars is consumed to overcome [...]
Superlubricity of carbon nanotubes as a prerequisite for mechanically activated ionic transport

31.08.2020 337 Views
The field of nanofluidics is the study of the behavior, control and manipulation of fluids that are confined in extremely small structures. The dimensions of these minute structures typically range from 1 nanometer to 100 [...]
Simulations explain why the ice is so slippery

Summary Taking a statistical approach to the condition monitoring of wind turbines is helping wind energy operators control their operation and maintenance costs. SKF is using its wealth of knowledge and considerable database about thousands [...]
Argonne Embraces Concept of "in operando" Formation of Carbon-based Tribofilms

23.08.2016 479 Views
Earlier this month, tribologists and physicists at the U.S. Department of Energy (DOE) Argonne National Laboratory published news of their (self-described) “self-healing diamond-like carbon coating [that] could revolutionize lubrication” in the journal Nature. The researchers [...]
