OLEM is equipped with advanced equipment for mechanical, thermal and rheological characterizations of materials, liquids and solids.


OLEM provides:

Surface mechanical testing at micro and nanoscale: tribology, friction and wear; nanotribology, nanoindentation and nanoscratch; adhesion of coatings to the substrate; nanoindentation with the tip of Atom Force Microscopy. Study polymer nanomaterials, ultrafine films, soft and hard coatings, ceramics and metals for mechatronics, micro and nanoelectronics applications.

Provide deformation and fracture tests of ultrafine films by unique "small punch test". Study mechanical strength in tensile, bending, compression and torsion of fibers, films, folia, small samples and electronic details in thermo-chamber (20-170оС).

Rheology in shear and dynamic mode of wide spectra materials: nanodispersions, polymers, oils, pastes, materials for food industry, cosmetics and pharmacy, dentistry and biomaterials.

Dynamic mechanical thermal analysis  (DMTA) in torsion, in wide range of amplitudes and temperature

Thermal analysis (DSC and TGA) of variety of materials.

Polymer nanocomposite processing and characterization.

Production of nanodispersions with graphene, carbon nanotubes and other nanoparticles in liquid phases.

Prototyping of details by FDM 3D printing.
