My collaborators Aimy and her student Ophelia presented two great talks about our ongoing work understanding how energy is generated and leveraged in the snap maneuvers of click beetles! Check out our prior paper for more details, and be on the lookout for at least 2 more publications this year! Many thanks to Sheila Patek […]
All PhD students in the lab had big leaps forward this semester.
Thank you to the faculty committee for their excellent feedback and guidance on Jiho’s presentation: “Lubrication mechanics in loosened polymer networks of polyacrylamide surfaces.”
Two weeks ago Jiho had the opportunity to participate in ‘Paper2Tree’ in which the lab supports the planting of a tree in the community to give back after publishing a journal articles. Following Jiho’s paper modeling duration-dependent lubrication earlier this year, he selected a Shingle Oak to be planted in King Park, and also led […]
Professor Dunn, Lihua, and visiting scholar Chao had a great time in downtown Chicago for the Tribology Frontiers Conference organized by Dr. David Burris from the University of Delaware. Professor Dunn presented Prabhakaran & Hao’s work on wear of hardened steels — take a journey under a train to get a feel for it. Lihua […]
Thanks for the opportunity to come by! You can listen here on SoundCloud to learn about how surfaces play an important role in design of materials, and why it’s important for the biomedical implants of the future!
Shab, Jiho, and Professor Dunn went up to Illinois Institute of Technology (Chicago) last week to present posters at the 4th annual workshop on Mechanics of Materials and Structures. The keynote speakers were excellent, Michael Ortiz from CalTech and Heinrich Jaeger from the University of Chicago, and we met many talented researchers working in all […]
How does a high-water-content hydrogel surface respond to step changes in speed? Jiho measured the lubrication mechanics of a complex shear interface through tribo-rheometry to try and figure it out. Out of all the possible responses, we find a combined time-dependent and shear-thinning response, just like a complex fluid. Check it out for more details.
Prof. Dunn worked with high school girls attending the Girls Building Awesome Machines (GBAM) camp here at Illinois last week to define tribo-corrosive wear using a system we can all enjoy: the Tootsie Pop! The last line of the classic commercial says that the world may never know “how many licks” it takes to get […]
We had a great time at STLE 2018 in Minneapolis. Both Shab and Jiho presented their work in the “Materials Tribology” track, and Chris, Prabhakaran, and Hao presented posters. Congrats to Chris on his poster award! Below you can see some of the nice contact area measurements he has been making over the past few […]
