Open Laboratory on Experimental Micro and Nano Mechanics (OLEM)

OLEM is a structural unit in the Department Fluid Mechanics.


OLEM Presentations:

Open Laboratory on Experimental Micro & Nano Mechanics (OLEM) was founded in 2010 and equipped under the Research Infrastructure Project DO-02-53, supported by the Bulgarian Science Fund, as well as by partial support from several European H2020 and FP7 Projects.

OLEM activities are focused on fabrication, characterization and application of polymer nanocomposite nanomaterials, as well as on education and training of young researchers.

OLEM is carrying a research on the development and characterization of polymer nanocomposites with graphene, carbon nanotubes, metal nanoparticles and clay, for functional and structural applications. The experimental and theoretical investigations are focused on approaches of fluid mechanics, surface mechanics, physical chemistry and physics. Methods of experimental and theoretical rheology, nanostructure characterization, thermal analysis, nanoindentation, tribology, deformation and fracture are mainly applied. Research results are expected to improve knowledge on the processing-structure-property relationships, percolation concept and interfacial phenomena for the design of nanocomposites with potential applications in electronics and mechatronics.

OLEM address is Acad. G. Bonchev Str., Block 4, 1113 Sofia, Bulgaria.
