This month we talk about understanding and optimizing tribological performance is vital for improving fuel efficiency, extending component lifespan, and reducing emissions in modern vehicles. Dr. Nolan Chu from Auburn University and Dr. Arup Gangopadhyay from Ford Motor Company will share insights into the complex computational models being developed to predict and mitigate wear in critical areas such as engines, transmissions, and brake systems. We’ll discuss the challenges of accurately simulating these real-world conditions and how this research translates into the next generation of more durable and efficient automotive technology. Tune in to learn how advanced tribological modeling is driving innovation on the road.

Our Presenters:

Dr. Nolan Chu received his bachelors in Mechanical Engineering and in Applied Mathematics - Actuarial Science from Auburn University in May 2016, his master's in Mechanical Engineering from Auburn University in May 2018, and my doctorate in Mechanical Engineering from Auburn University in May 2023. His work as a graduate student mainly focused on modeling engine components to evaluate friction reduction strategies, but also worked on elastic and elastic-plastic rough surface contact models.

Dr. Arup Gangopadhyay is a technical leader of powertrain tribology in energy, propulsion and sustainability in research and advanced engineering at Ford Motor Co., where he has worked for more than 30 years. His research focus is on reducing friction and wear in powertrain systems, as well as understanding the interaction between lubricant additives and surfaces and coatings, with the ultimate goal of improving fuel economy. He has published 80 technical papers, holds a number of U.S. patents and was awarded the Engineering Society of Detroit’s Gold Award in September 2020, which honors exceptional engineers and scientists. He has served as a board member for the STLE Detroit Section since 2000 and also served two terms as an STLE board member. He was elected an STLE Fellow in 2004.

This podcast episode explores the fascinating world of tribology as it applies to everyday fasteners. Tribology, the science of friction, wear, and lubrication, is the unsung hero behind the function of countless devices we use to hold things together or secure them. From the thousands of tiny hooks and loops that make up Velcro to the teeth and locking mechanism of a zip tie, and the knots in shoelaces or the mechanics of snaps, these seemingly simple devices rely fundamentally on controlling and manipulating friction. We'll delve into how these tribological principles enable us to perform both routine tasks—like securing a jacket—and more critical operations, ensuring that the devices we depend on to tighten and connect components remain reliable under stress. Tune in to discover the hidden engineering that keeps our world—quite literally—fastened together.

Our Guests:
Melissa Mushrush has been a chemist for the MOLYKOTE® Specialty Lubricants brand since 2017, specializing in anti-friction coatings to improve friction and wear performance. She brings expertise in vacuum technology, thin-film deposition, material characterization, process data management, and accelerated testing methods. During her 14 years at The Dow Chemical Company, Melissa worked on diverse projects, including polymer light-emitting diodes and thin-film solar technology. She played a key role in establishing Dow’s solar expertise, collaborating with institutions like NREL and the University of Delaware. Melissa’s career reflects a strong focus on innovative materials research and practical industrial applications.

Katherine Helmetag is an organometallic chemist with BS and MS degrees from Drexel University. She has been working in tribology since the start of her career and has focused on lubricant design for all types of metalworking operations. Katherine’s current role as a process engineering manager for Henkel NA Operations has her focused on operation excellence in the chemical manufacturing industry. She mentors Team#2960 of FIRST Robotics as the materials lead and volunteers with Scouting America as a Unit Commissioner and Merit Badge Counselor, and enjoys instructing HPDE events around Michigan.

Both Christine and Kathy were also guests on our January 2025 Perfecting Motion episode on the Tribology of Footwear.

The History of Tribology in History Part II - From Byzantine Ingenuity to Da Vinci's Genius

Welcome back to the second installment of our series on the history of tribology. In this episode, we're delving into the fascinating period from the Byzantine Empire through the Renaissance. We'll explore how Byzantine engineers applied advanced knowledge of friction, lubrication, and wear to create remarkably durable machinery, from intricate siege engines to complex water-lifting devices. Their practical innovations laid a crucial, often overlooked, foundation for later advancements.

The episode then shifts to the Renaissance, where we'll highlight the extraordinary contributions of Leonardo da Vinci. A true pioneer, Da Vinci moved beyond mere observation to scientifically investigate the laws of friction, recording his findings in his notebooks centuries before they were formally understood. His work provides a stunning example of how tribological principles were integrated into art, engineering, and invention, from his designs for flying machines to his revolutionary ball bearings. Join us as we uncover how ancient ingenuity and a single genius's curiosity shaped the world of motion and mechanics.
