After the remarkable success of the four first editions of the African Conferences in Tribology in 2014, 2017, 2022 and 2023, we are happy to announce the 5th African Conference in Tribology (ACT 25) that will be held in Tunis (Tunisia) from April 28 to April 30, 2025.

This 5^th ACT will focus on current and future tribological challenges to be addressed by both academic and industrial researchers to improve our future.  Such challenges include the impact of tribology on human health, the environmental impact of tribology, etc. Once again, strong interactions between the academy and industries from all over the world are expected.

Consequently, the program committee cordially invites research ideas in (but not limited to) the following suggested range of subjects:

• tribology in transportation
• tribology in industry
• tribology in the space environment
• tribology in energy production
• nano-scale tribology
• local and global contact measurements
• multi-scale and multi-physics modeling in tribology
• smart tribology
• …and others. 

A satellite forum on Biomechanics, Biomedicine, Biomaterials and Digital Health will also take place where your contributions are welcome.
