FEATURES

20 MINUTES (STLE MEMBER BONUS CONTENT)
20 Minutes With… Balasubramaniam (Bala) Vengudusamy
This senior tribology expert discusses wind turbine lubrication and how he got in the lubricants and tribology industry.

20 MINUTES
20 Minutes With Darius Faizi
This director of product management for Tomlin Scientific discusses grease and the lubricant space.

LUBRICATION FUNDAMENTALS
Slippery and sticky?
A lubricant must have a dual nature to establish a plane of slipperiness between objects.

FELLOWSHIP RESEARCH
Tribological Properties of Lubricating Oil Upcycled from Plastic Wastes (LOUP) Under Electrified Conditions
Tribology research report written by the recipient of STLE’s 2024 scholarship program.

 WEBINAR

Machine learning and artificial intelligence in tribology
Artificial intelligence has the potential to solve big problems.

FEATURE 

Quantifying sustainability
Several carefully developed, credible methods exist. The key is choosing the best framework for the application.

TECH BEAT I 

Tribology’s role in pitching a baseball
Rubbing Mud, composed of clay and sand, produces the higher friction and adhesive forces that allow the pitcher to better grip the baseball.

TECH BEAT II 

Sustainable anolyte for use in nonaqueous redox flow batteries
Researchers have synthesized a derivative of TPPO that exhibits a similar high negative potential but is also more stable under the operating condition needed.

TECH BEAT III 

Fuel economy benefit of rotating liner engine
By enabling the cylinder liner to rotate, metallic contacts among compo­nents in the piston assembly are mini­mized leading to a predicted fuel economy benefit of the order of 7.5%. 

SOUNDING BOARD
