The next annual ELyT Lab Workshop on March 12 to 14, 2012 in France
The 4th ELyT Lab workshop will be held in France from March 12 to 14, 2012, in Presqu'ile de Giens (south east).
ElyT School in Lyon 2011
The third edition of the ELyT School was held from the 4th to the 14th of September 2011 in Lyon with the visit of 30 students (20 PhD and 10 Master students) accompanied by four professors from Tohoku University.
The 3rd ELyT lab workshop
The 3rd ELyT lab workshop, held in Sendai during 3 days from February 22th to 24th 2011 has been a great success, involving about 100 researchers (among them 35 French attendees) and several industrial partners. This confirms the dynamism of our joint laboratory. Program and some presentations can be downloaded here. The website is regularly updated.• Biosciences & Engineering (B), • Durability, Reliability in Energy and Transportation (R), • Nano & Micro Scale Materials & Devices (M), • Flow Dynamics, Heat Transfers and Microfluidics (F), • Tribology (T)
Tribology deals with the understanding of contact including friction, wear and lubrication mechanisms. In this field, there is a long history of collaboration between Ecole Centrale de Lyon and Tohoku University that has been initiated by Prof. K. Kato in Tohoku and Prof. J.-M. Georges in ECL more than 20 years ago. This cooperation has been reinforced and extended since 2004 with the IRCP project on smart materials with the exchange of more than 8 Japanese and French researchers. Recently, the collaboration between our two universities has mainly concerned the tribology of carbon-based thin layers with complementary approaches both in the tribological characterization of these surfaces and their elaboration. Four main topics will be developed in the common laboratory that will involve the Laboratory of Tribology and Systems Dynamics (LTDS, ECL), the Laboratory of Contacts and Structures Mechanics (LaMCoS, INSA), the School of Mechanical Engineering and the Institute of Fluid Science (TU). The two first projects have been applied for NEDO funding in January 2008.
TRIBOCHEM: Computational chemistry of lubrication additives in boundary regimes: Dr. C. Minfray from ECL and Dr M. Kubo from Toholu University. In this sub-project, the dynamics of tribochemical reactions within lubricants submitted to high pressure and high rates will be modeled by quantum chemistry. The obtained results combined with tribological experiments and advanced chemical and mechanical surface analysis will be used to describe the action mechanisms of lubricant additives.
NaSMoTI: Nano scale modeling of tribological interfaces: Dr. Ph. Vergne from INSA Lyon and Dr. T. Tokumasu from Tohoku University. The aim of the project is the modeling the flow dynamics in thin film lubricated contact by the use of molecular dynamics.
FrictionNoise: Friction and contact noise: Prof. H. Zahouani from ECL and Dr. K. Adachi from Tohoku University. The aim of the project is the understanding of the dynamics of multi-asperity contacts, undergoing low pressure. In that case, the acoustic emission induced by the sliding is mainly due to the topography of the surface and the roughness parameters.
CarbonCoat: Friction and wear control by carbon layers: Dr. J. Fontaine, from ECL and Dr. H. Miki, from Tohoku University. The objective of this project is the development of multifunctional carbon layers (hydrogenated DLC, doped DLC, CNx films, …) for friction reduction and in-situ contact sensors
