Facilities to obtain nanostructured materials:

Spray pyrolysis method to obtain nano-crystalline materials, coatings - the facility itself is made with two spray guns, nitrogen as a carrier gas, the substrate can be heated up to 450 ° C (regulated heating/cooling speeds available) for samples with dimensions no larger than 40x40 mm.

Electrochemical deposition method to obtain nanocrystalline thin film coatings, using VoltaLab 40 (PGZ301; Radiometer Analytical) potentiostat with software VoltaMaster 4 and/or self-made impulse power supply.

Electrochemical anodising method for obtaining self-organized nanostructured oxide layers on the metallic substrates; consisting from a DC power supply, digital thermometer and data logger with the opportunity to register current/potential/temperature changes during film growing process.

Few layer graphene (FLG) sheet exfoliation method using graphite electrodes and self-built pulse generator; material washing/filtering facilities. Electrochemical exfoliation of graphene sheets from graphite electrode can be arranged simultaneously with reduction of graphene oxide, as well as with insertion of different ions and cations between the graphene sheets.

  

Facilities for the optical and photo-electrochemical studies of materials:

Spectrometer HR4000 UV-NIR with the program SpectraSuite and UV + VIS + NIR light source DH-2000 for studying light transmission/scattering of materials, and emission spectra of different light sources;

System to investigate photo-electrochemical properties of materials and coatings built from self-made electrochemical cell, light source (150 W high-pressure xenon lamp and/or 30 W LED flood light), light modulator and VoltaLab 40 (PGZ301; Radiometer Analytical) potentiostat with VoltaMaster 4 software.

  

Facilities to study physical and physico-chemical characteristics of the materials:

Gas sorption analysis system PCTPro-2000 (SETARAM) with mass spectrometer RGAPro-100 (up to 100 mass/charge number units). The device is intended to study gas sorption/desorption characteristics for various materials (now available only hydrogen gas) and various gases (currently - hydrogen) following SIVERT (volume change) method. Applications - new materials for gas storage, permeation.

Selective gas permeability studies in self-made differential pressure detection chamber for flat (membrane) samples and cylindrical (outer diameter 10 mm) samples.

Conductivity measuring system to determine ionic conductivity of polymer membranes in the temperature range from room to +80 ° C, consisting of a sample holder BekkTech BT-512 and water thermostat bath.
