Mini Micro Nano Project [Mini Micro Nano Project]

A new field of interest is the use of metallic materials in MEMS applications because of their interesting mechanical and wear properties. The objective of the Mini Micro Nano Project is to create a center of excellence in the field of micromechanical engineering with the cooperation of three ULB partners: the CAD-CAM, the Structural and Material Computational Mechanics and the Industrial Chemistry departments.The nanoscale world obeys to different rules than the macroscopic one. Due to the extreme down-scaling many practical problems are encountered in microhandling of small parts. These problems must be studied and solved in order to be able to design and produce reliable micromechanical tools. The CAD-CAM department is in charge of the development of a tool for surface interactions to be able to take into account the surface forces (that are of the outmost importance at nanoscale) for manipulator design and for the development of handling strategies.At small scales the behavior of materials changes significantly with respect to the bulk material at macro-scale, which leaves many unanswered questions. The Structural and Material Computational Mechanics Department is responsible for modeling the mechanical response of materials at nanoscale using appropriate theories to pass from the bulk material parameters to the nanoscale behavior.The previous tasks need inputs from special experiments. The practical research results must also be validated later on. The Industrial Chemistry Department brings its expertise in experimental characterization of materials and performs thorough chemical and physical characterization of materials and surfaces.The project will span five years, with the participation of three PhD students attached to the fore-mentioned three departments during four years and one post-doctoral fellow for the last two years.
