Boundary Lubrication Boundary lubrication is the lubrication regime where the interface behaviour is dominated by chemical reactions that happen at the surfaces, tribofilm formation occurs, and the load is carried by the asperities. In the boundary lubrication regime the […]

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 friction. [...]
Sequential nature of the electrochemical reduction of carbon dioxide

By Dr. Neil Canter, Contributing Editor | TLT Tech Beat July 2023 Chronoamperometric analysis was conducted to study how the electrochemical current produced during the reaction changes over time as the applied potential changes. HIGHLIGHTS [...]
Employing machine learning to create wear and corrosion resistant metallic glass

If you combine two or three metals together, you will get an alloy that usually looks and acts like a metal, with its atoms arranged in rigid geometric patterns. But once in a while, under [...]
Simulations explain why the ice is so slippery

21.05.2018

Everybody knows that sliding on ice or snow, is much easier than sliding on most other surfaces. But why is the ice surface slippery? This question has engaged scientists for more than a century and [...]
Superlubricity between steel surfaces with glycerol/water mixture lubricant

It is estimated that the energy lost due to friction in industrialized countries equals to approximately 5% of their gross national products and it is clear, that reducing the friction is highly desirable. The classical [...]
