FELLOWSHIP RESEARCH
In-situ tribometry for understanding the near ultralow wear of neat PTFE
Tribology research report written by the recipient of STLE’s 2022 scholarship program.

LUBRICATION FUNDAMENTALS
Viscosity index and classifications
Operating temperature impacts viscosity at a rate that is unique to the oil in use.

WEBINAR

Bioinspired surface micro/nano-topography engineering for tribological applications
Nature provides the inspiration, and 3D printing provides the fabrication for textured surfaces that reduce friction, wear and deformation.

FEATURE ARTICLE

Metalworking fluid basics
There are many key operational issues and future challenges facing end-users.

TECH BEAT I 

Tribology of breast implants
The objective is to use tribology to design breast implants that minimize patient complications.

TECH BEAT II 

Ionocaloric refrigeration
The refrigeration process is triggered by a solid-to-liquid phase transition involving the addition of a salt.

TECH BEAT III

Interfacial transverse shear and friction
Modulated nanoindentation was used to perform experiments to determine interfacial transverse shear modulus.

SOUNDING BOARD 

Oil analysis
Readers share their insights on oil analysis.
