A theoretical background to the Hertz contact theory can be found here. Line Contact (Cylindrical contact) In case of two cylinders in contact (with radii ), as shown in Fig. 1, the Hertzian radius of […]

Keeping the Wind in Your Sails

19.07.2017

Just like any mechanical device, a wind energy system needs timely, appropriate lubrication in order to function reliably and predictably. Wind turbines routinely withstand extremely demanding conditions: vibration, high mechanical loads, contamination and moisture are [...]
Employing machine learning to create wear and corrosion resistant metallic glass

23.04.2018

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 [...]
Triboelectric generators can be used to improve mass spectroscopy sensors

10.05.2017

[embedded content] Triboelectric nanogenerators convert mechanical energy harvested from the environment to electricity for powering small devices such as sensors or for recharging consumer electronics. Now, researchers have harnessed these devices to improve the charging [...]
Antiwear tribofilm growth - AFM study

14.03.2016

In a wide range of tribological components, the lubricant is not capable of separating the surfaces and areas of metal-to-metal contact occurs. However, the metal-to-metal contact area can be minimized by the action of additives, [...]
