Testing of chemical composition of historical plaster

The composition of a sample of historical plaster with polychromic residues was established on the basis of analysis of absorption spectra in infrared conditions. They found that t...

Testing of inks containing carbon nanotubes printed on various polymer films

The object of the tests was conductive ink containing multiwall carbon nanotubes. The ink was printed on polycarbonate film (PC) and copolymer polycarbonate and po...

Determination of distribution of diameters and electric conductivity properties

Single wall nanotubes delivered for tests had been grown with the use of CVD method. Tests on distribution of diameters of nanotubes were conducted as based on position of RGB stra...

Testing of CVD technology of growth of multiwall nanotubes

This method can be an alternative to more cost-consuming processes, if there are no stringent requirements as to morphological properties of the material. The figures present SEM i...

Testing of chemical composition of sealer samples on historical gold plating

The tests were made as based on analysis of absorptive spectra of varnish samples in infrared conditions. On the presented figure there are visible wide strands from OH, NH, CH, CH...
