I deposited a PPY film on FTO via electro-polymerization. I need to get the conductivity of the films, but I don't have access to the four probe method. Is it possible with the potentiostat?
Hello, Does anyone know where we could purchase a used NIRS system, for example, by Artinis or NIRx? Thank you. Greg
