Roughness is known to be an important factor in friction, wear and related performance of the machine parts. It was shown recently that Power Spectrum Density (PSD) can be used as a metric to describe […]

In specially coated tubes, the more viscous liquid flows faster

25.01.2021

The rate of flow of different types of fluids moving along pipes has critical ramifications when you consider physiological functions like the cardiovascular system. The speed of blood flow through the heart and its network [...]
Is there a Future for the Internal Combustion Engine?

02.12.2019

As regulations regarding traditional automobiles and emissions become tighter around the world, the future of the internal combustion engine becomes more uncertain, which is a great concern to those involved in the lubricant business. However, [...]
A Better Way to 3D Print Metallic Glass

25.10.2018

In the last several years, 3D printing with plastics has advanced rapidly. Now, a team of researchers have shown that it may soon be as easy and practical to use metals with 3D printing. Led [...]
Nordtrib 2016: conference summary and outlook on the field of tribology 50 years after the Jost report

19.06.2016

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 [...]
Droplet friction is similar to solid friction

21.11.2017

Researchers of the Max Planck Institute for Polymer Research have investigated friction of liquid droplets on surfaces. A larger force is needed to set in motion stationary droplets than to keep moving droplets in motion. [...]
