Keynote Speakers:

Control of ionic liquid boundary lubricants with electric fields

Mark Rutland

KTH Royal Institute of Technology (Sweden)

Ionic liquids have received much attention as tribological additives and lubricants, due to their tuneability but also due to the possibility of controlling the surface composition using an applied field. This electrically addressable boundary lubrication depends on the intricacies of the interfacial ordering of ionic materials, which is dependent on self assembly and coulombic interactions. Experimentally these films are very inaccessible and require the development of new methodologies to probe them.

The lecture will discuss the principles of lubrication by liquid salts and, what approaches can be deployed to quantify the relationship between the observed tribology and nanotribology , and the changing ionic compositions under electric fields.

A surface chemist turned nanotribologist from Australia who has lived and worked in Sweden for 25 years. A PhD (1992) from the Australian National University in surface forces, postdocs at Lehigh University and The Institute for Surface Chemistry Stockholm followed by 4 years lecturing at the University of Sydney. At KTH The Royal Institute of Technology in Stockholm since 1998, professor since 2005. The surface has always been the focus, with interfacial self-assembly as an early theme. Interdisciplinary connections include (nano)tribology and psychophysics, with applications ranging from electroresponsive interfacial behaviour, through biolubrication, pharma and cosmetics.

On hydrodynamic lubrication equation under non-steady work conditions

Yonggang Meng

Tsinghua University (China)

The classical hydrodynamic lubrication equation, known as Reynolds equation, and its various modified forms, were derived on the basic assumption of fluid flow through a narrow gap between moving parts under steady conditions, and thus are not applicable to situations of non-steady work conditions. Taking three dynamic effects, acceleration/deceleration of the moving part of conjunctions, non-steady variation of the boundaries of lubricated zone and the time-dependent rheology of the fluid, into account, an expanded Reynolds equation is derived. It is pointed out that the hydrodynamic lubrication problem under non-steady conditions is no longer defined solely by the lubrication equation, the complementary equations governing the dynamics of the conjunction parts, fluid flow outside the lubricated zones as well as the rate-, state- and temperature-dependent rheology model of fluids are required to solve the problem. The new equation has been applied to analyze the variations of fluid film thickness of a plain bearing with time during acceleration and deceleration periods, and compared with the experiment results of a test rig in literature.

Dr. Yonggang Meng is a Professor in Mechanical Engineering at the State Key Laboratory of Tribology in Advanced Equipment, Tsinghua University, Beijing, China.

Scope:  Tribology exists in every mechanical system that supports the industrial society, and it holds the key to their functions, reliability and durability. Therefore, the evolution of science and the development of technology in the field of tribology have progressed from an engineering point of view. This symposium session will provide an opportunity for information exchange and discussion on tribology related to engineering products on the basis the latest research results. We will select a variety of presentation from the tribology inherent in the engineering products as well as the fields related to the keywords on the list.

  Mari Onodera  Panasonic Industry, Japan
  Nicolas Fillot  INSA Lyon, France
  Lars Pastewka  Albert-Ludwigs-Universität Freiburg, Germany
Scope:  Since tribology is a part of mechanical and chemical engineering, computer aided engineering should be useful. The complexity and dynamic nature of the system is, however, made difficult to apply the tool. In these 20 years, molecular simulation and fluid dynamics approach combined with high performance computing made significant progress to this field. More recently, not only the computational science but also data science is also becoming an important tool in this field. In our session Modeling of Tribology, we would discuss recent progress in both computational science and data science approach to a wide field of Tribology. Not only pure computational science but also combination with experiments will be discussed.

Keynote Speakers:

Structural evolution of solid lubricants under high pressures

Michael Moseler

Freiburg University (Germany),
Fraunhofer Institute for Mechanics of Materials IWM (Germany)

Solid lubricants such as graphite, multiwall carbon nanotubes and PTFE can be used in low-pressure applications. Until now, it was unclear whether their lubricity is also sufficient for high contact pressures, for example in rolling bearings. This lecture demonstrates that high pressure solid lubrication is a viable option when liquid lubricants fail. Furthermore, it provides deep insights into the mechanism underlying solid lubrication by PTFE, graphite and multiwall carbon nanotubes. Classical and quantum molecular dynamics simulations along with experimental tribometry and analytics reveal the crucial role of structural transformations in the solid lubricants and their impact on lubricity. While PTFE chains align during pressurized sliding, graphite and multiwall carbon nanotubes form new amorphous carbon tribomaterials with intermediate range order. For the latter two lubricants, water plays a crucial role in passivation of the observed turbostratic carbon tribolayers.

Prof. Dr. Michael Moseler is a German Physicist and Materials Scientist with a strong focus on atomistic modelling of friction and wear as well as nanomaterials. He holds a Professorship for “Simulation of Functional Nanosystems” at the Physics Department of Freiburg University and he is leader of the applied research group “Multiscale modeling and Tribosimulations” at the Fraunhofer Institute for Mechanics of Materials IWM. His research activities cover classical and quantum molecular dynamics simulations of tribo-induced phase transitions, rheology and reactivity of lubricants in narrow gaps as well as fundamental mechanisms underlying superlubricity.

Toward Post-exascale Simulations of Materials Interfaces

Aiichiro Nakano

With the recent arrival of exascale supercomputers, computing landscape is evolving rapidly. While quantum computers have outperformed the fastest supercomputers for certain problems, artificial intelligence (AI) is transforming every aspect of our life. To utilize these new advances for materials simulations, we are developing an AI and quantum-computing enabled exascale materials simulator (AIQ-XMaS). I will describe the application of the software to quantum, reactive and neural-network simulations of interfacial phenomena, including: (1) picosecond optical, electrical and mechanical control of symmetric breaking in topological skyrmion and skyrmionium at ferroelectric/paraelectric interfaces for emerging ultralow-power polar topotronics; and (2) self-assembly of layered material metastructures on strained substrate for scalable and robust manufacturing of quantum emitters for future quantum information science and technology. This research was supported by NSF Future Manufacturing Program, Award 2036359 and NSF Cybertraining Program, Award 2118061. Simulations were performed at Argonne Leadership Computing Facility under DOE INCITE and Aurora Early Science programs and at the Center for Advanced Research Computing of the University of Southern California.
