Relationship Between Physical Characteristics of Cereal Polysaccharides and Soft Tribology-The Importance of Grain Source and Malting Modification. [PDF]

Food Sci Nutr
The physical characteristics of the main starch and non‐starch polysaccharides in worts were characterized. The lubrication behaviour of the worts was analyzed by soft tribology. The data analysis showed the relationship between the molar mass and conformation of these polysaccharied and lubrication behaviour in laboratory‐produced worts.

Positive Effect of Periodic Micropatterns on Compression Ring Friction

Advanced Engineering Materials, Volume 25, Issue 14, July 2023., 2023
For internal combustion engines, reducing friction is becoming increasingly important to reduce emissions. It is shown that laser‐interference‐induced microtextures on amorphous carbon‐coated piston rings are able to significantly reduce the friction of the piston assembly when tested in single‐cylinder engines.

Transient torque reversals in indirect drive wind turbines

Wind Energy, Volume 26, Issue 7, Page 691-716, July 2023., 2023
Abstract The adverse effect of transient torque reversals (TTRs) on wind turbine gearboxes can be severe due to their magnitude and rapid occurrence compared with other equipment. The primary damage is caused to the bearings as the bearing loaded zone rapidly changes its direction.

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

The Effect of Temperature and Physical State of Water on the Frictional Properties of Chlorite‐Altered Basaltic Gouges (Krafla Geothermal Field, Iceland)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Changes in the physical state of water may alter fault frictional properties in high‐temperature geothermal systems, yet they have been little studied. Here, we perform slide‐hold‐slide experiments to examine the frictional properties (frictional strength μss and frictional healing Δμ) of chlorite‐altered basalt from Krafla Geothermal Field ...

A temperature rise calculation model of wind turbine gearbox gear considering crack fault and tooth number difference

IET Renewable Power Generation, Volume 18, Issue 15, Page 3416-3428, 16 November 2024.
A temperature rise calculation model of wind turbine gearbox gear considering crack fault and tooth number difference is proposed. The data of high‐speed gear of a wind turbine gearbox in northern China is selected for simulation verification. By comparing with the finite element method, the effectiveness of this method is verified.
