E-Chem

Laboratory of electrochemistry

The e-chem lab is equipped for performing a wide spectrum of accurate and reliable photo-electrochemical characterizations of nanomaterials. Thanks to this lab, CIMaINa scientists are able to get detailed information about the surface chemistry, the electronic structure, and the morphological properties of these materials. Among the applications that could benefit from the results of the studies that are being carried out in the e-chem lab one can mention supercapacitors, solar cells, field-effect transistors.

The e-chem laboratory also hosts a BET facility, which exploits nitrogen adsorption to get quantitative information on the total surface area and porosity characteristics of powders, polymers, and nanostructured thin films (in particular it is possible to calculate the total surface area, the area and volume of micropores by means of the t-plot method, the pore size distribution by means of BJH analysis and total pore volume).
