Since 2013 Dr. Espinosa-Marzal is an Associate Professor at the University of Illinois at Urbana-Champaign (UIUC) in the departments of Materials Science and Engineering and Civil and Environmental Engineering. In 2016, she was awarded Associate to the Center for Advanced Study at UIUC to recognize her work on ionic liquids under confinement, and in 2019 she received the Deans Award for Excellence in Research. Dr. Espinosa-Marzal has a Ph.D. in materials engineering from Hamburg University of Technology (Germany). After her Ph.D., she received an award to promote academic career of young researchers from the German Research Foundation (DFG), which brought her to Princeton University as a research fellow. Prior to joining Illinois, Dr. Espinosa-Marzal spent four years as senior scientist in the laboratory of surface science and technology in the Materials Science Department at the ETH Zurich in Switzerland. Her research interests include understanding the molecular mechanisms underlying friction, lubrication and wear of lubricated contacts. She has published over sixty peer-reviewed manuscripts. Since 2016, she serves as member of the executive committee of the Division of Colloids and Surface Chemistry at the American Chemical Society in the role of membership secretary.

“Polymers and composites- Versatile tribo-materials

Amongst engineering materials viz. metals, ceramics and polymers, polymers and their composites/nano-composites filled with various fillers/solid lubricants/ abrasives/reinforcements find immense applications in very diverse areas of tribology because of their unique property profile. These are most light-weight materials having highest specific strength, self-lubricity (in general), resistance to corrosion, impact, shocks and vibration (leading to damping capability) apart from easy processability leading to cost-effective components ready to use especially by injection molding. In case of tribological aspects, they have amazing spectrum of friction and wear characteristics leading to their exploitation in diverse application-sectors categorized based on magnitude of friction and wear. Polymeric dry bearings, bushes, gears, slides, seals, prosthetic joints etc. (demanding for low µ, low wear) form one of the application areas while moderately high friction and low wear are sought for applications such as brake-materials, tyres, etc. One of the very interesting areas is of polymeric adhesives requiring very high friction and zero wear. The talk describes about these multi-faceted materials with special reference to bearings, brake-material and adhesives.

“Tribocorrosion solutions: the only way to mitigate the consequences of systems subjected to wear and corrosion interaction

Anna Igual Munoz is Professor at the Technical University of Valencia (UPV, Spain) in the Chemical and Nuclear engineering department and at present in a sabbatical period at Ecole Polytechnique Fédérale de Lausanne (EPFL) in the Tribology and Interfacial Chemistry lab (TIC). She has a master degree in Industrial engineering (specialized in chemical engineering) and a PhD in Electrochemical corrosion (2001) from UPV. She did a Postdoctoral research at the University of Virginia (USA) in 2002 in the field of electrochemical impedance spectroscopy and local electrochemical techniques. She created and leads the Tribocorrosion research Group at UPV. Her scientific interests are mainly focused in the understanding the interactions (chemical, mechanical and biological) between materials and surfaces (mainly metals and oxides) with the environment. Mainly in the fields of corrosion, tribology and new functional coatings.

Presentation title
“Fundamental Investigations of Cavitation Damage Mechanisms using Single Laser-Induced Bubbles

Stefanie Hanke is a researcher and lecturer at University Duisburg-Essen, Germany, in the field of Materials Science, Tribology and Failure Analysis in Mechanical Engineering. She completed her Ph.D. in 2014, studying the effect of thermomechanical microstructure modifications on the tribological behavior of various metal alloys. As post-doctoral scientist, she headed a research group for surface modification by solid state joining techniques at Helmholtz Center Geesthacht, Germany. Amongst others, she accomplished a first in-situ study of phase transformations in Ti-alloys during Friction Surfacing using Synchrotron radiation. Back at University Duisburg-Essen since February 2017, she is now head of the research department of Materials Science in Mechanical Engineering. The group is focused on the correlation of microstructural mechanisms of damage accumulation and failure initiation, both under fatigue and tribological loading. This includes the phenomenological and mechanism-based analysis of sliding wear and cavitation erosion behavior of martensitic and austenitic steels, as well as Al- and Cu-based alloys for various engineering applications.
