Oil lubrication and lubrication technologies are essential in reducing friction and wear losses in machines. The key in efficiency of the frictional system is a lubricant (grease, oil, solid lubricants). Four Ball Tester, also known […]

Principles of Green Tribology

23.12.2019

Peter Jost first used the term tribology in 1966 to describe the studies of science and technology that aim to understand how surfaces in relative motion to each other interact and the effects those interactions [...]
An Open Access Tribology journal is launched

14.05.2018

Chief Editors Professor Valentin Popov and Dr. Roman Pohrt will foster multidisciplinary knowledge exchanges on tribology — a subject integral to any system with moving parts. Tribology — the study of friction and wear — [...]
Triboelectricity to collect wave power

01.06.2017

Nature provides three sources of energy for free: sunlight, air and gravity. Solar and wind power are increasingly exploited, gravity less so. Hydraulic power plants harvest energy from flowing rivers. Tidal energy can be gathered [...]
Reformulating Lubricating Oils to Improve Engine Performance

14.07.2019

Reformulating lubricating oils for the internal combustion engine could result in an improvement in the life of the oil and engine itself, according to a recent article by Dr. Pranesh Aswath. Dr. Aswath and colleagues [...]
Inverse Friction Force - Load Dependence of Graphene

03.03.2016

When the bodies slide against each other, the classic Amonton’s law states that the friction force is directly proportional to the applied normal load. This law holds true for various if not most of the [...]
