Superlubricity: The energy saving superhero for new products
24.01.2022 Clarissa Wright

The article is sponsored by Bruker. Friction is the great obstacle to overcome when testing new products with moving parts. While friction can never disappear completely, it may be possible to achieve ultralow friction: a […]

Atomistic Tribology
Achieving superlubricity with high temperature
09.08.2021 Nikhil Kunapareddy

Lubrication between two surfaces depends on their respective co-efficient of frictions, surface finishes and also the type of lubricant used, if there is any. It is known that the temperature at which these surfaces  are […]

Mechanically activated transport

Superlubricity of carbon nanotubes as a prerequisite for mechanically activated ionic transport
31.08.2020 TriboNet

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 […]

Nordtrib 2016: conference summary and outlook on the field of tribology 50 years after the Jost report
19.06.2016 Dennis Ernens

Nordtrib 2016 came to a close last Friday and I returned home inspired and energized for the next stint in my PhD research. This post is an overview of the conference and summarises the outlook […]

Decrease Friction with Hydrogen Ions
13.06.2016 Aydar Akchurin

Currently, a large portion of consumed energy is used to overcome friction. Design of low friction components is a primary goal in building a sustainable society. Superlubricity, the state of ultralow friction (<0.01), has already […]

Ab Initio Analysis of Carbon Film Lubricity
16.05.2016 Aydar Akchurin

Carbon-based nanomaterials, coatings and films attracted a great attention due to proved possibility to achieve lowest friction and wear without environmental pollution. However, frequently, the state of the low friction is strictly related to the […]

The Mechanism of Glycerol Superlubricity
09.05.2016 Aydar Akchurin

Glycerol is a highly viscous liquid, generating friction coefficient of 0.1 and up for bearing steels in boundary lubrication. In full film EHL, pure glycerol generates high friction as well and therefore is rarely used […]

AFM vandwaals superlubricity
Atomistic Tribology
Superlubricity by means of repulsive van der Waals forces
06.04.2016 Aydar Akchurin

Superlubricity, a state of low friction (<0.001), can be achieved by different mechanisms. The structural superlubricity occurs, if the crystal lattices of the contacting bodies are incommensurate. Nano-scrolls may act as a bearing and may […]

Superlubricity of nanodiamonds glycerol colloidal solution
22.03.2016 Dennis Ernens

Earlier we reported about superlubricity achieved with a mixture of water and 30 [wt%] glycerol by researchers from Tsinghua University, Beijing. The same investigators just published a paper using this as a base lubricant and […]
