Open Laboratory on Experimental Micro and Nano Mechanics (OLEM)
OLEM is a structural unit in the Department Fluid Mechanics.
Research Topics of OLEM:
Multifunctional polymer nanocomposites with graphene and carbon nanotubes:
Rheological, micro and nanomechanical investigations of reinforcing effects of nanofillers in polymers. Control on nanofiller dispersion and nanofiller-polymer interfaces. Evolution of nanocomposite properties improvements around percolation threshold. Rheology-structure-properties relationships. Development of novel nanomaterials for functional and structural applications.
About Open Laboratory:
OLEM is established in 2009 within а Research Infrastructure Project, supported by the Science Fund of Bulgaria. The Open Laboratory operates at national and international level for nanocomposite fabrication and characterization, and mechanical tests of nanomaterials at macro-, micro- and nanoscale.
OLEM has 3 laboratories:
- Laboratory for micro and nanomechanics of materials
- Laboratory for rheometry and thermal analysis
- Nanotechnology Laboratory
OLEM Laboratories are well equipped for nanocomposite processing, rheology, thermal analysis, mechanical properties characterization, 3D printing and electrospinning.
OLEM is an attractive base for training of young researchers, students and engineers, who gain experience in advanced techniques for nanomaterials characterization.
OLEM address is Acad. G. Bonchev Str., Block 4, 1113 Sofia, Bulgaria.
