In Part 2 of TribologyTalks, Dr. Alexander MacLaren dives into the Space Layer Imaging Method (SLIM). This technique, capable of measuring lubricant films less than a micron thick, is transforming how we approach efficiency in automotive and aerospace applications. Dr. MacLaren reveals the challenges of interpreting SLIM's colorimetric data and shares how his collaboration with UPenn led to breakthroughs in overcoming these hurdles. Tune in for more.
