METHOD FOR MODIFYING AN ELECTRICALLY CONDUCTIVE OXIDE SURFACE, USE FOR ELECTRODEPOSITION OF COPPER ON SAID SURFACE

1. Method for modifying the surface of an Indium Tin Oxide (ITO) substrate, said method comprising the following steps consisting in:i) bringing into contact the surface of said ITO substrate with a solution containing at least one copper ion (Cu2+) and at least ammonia then washing and optionally drying the surface of said ITO substrate thus obtained;
ii) bringing into contact the surface of said ITO substrate obtained following step (i) with a solution containing sodium tetraborohydride then washing and optionally drying the surface of said ITO substrate, whereby the ITO substrate surface that is obtained after step (ii) is a modified surface that does not present nanoparticles or clusters of copper.

METHOD TO REGENERATE OXYGEN TRAPS

CENTRE NATIONAL DE LA REC...

1. A method to regenerate an oxygen trap using an electric current, comprising at least the following steps:a) circulating, by a circuit and a voltage source, an electric current in a material of the trap to reduce the material;
b) measuring, by an ammeter, a value Im of said electric current and estimating a derivative dIm/dt of the measured current Im in relation to time;
c) estimating, by a calculator, a length (?) of material reduced by said electric current, as a function of the value of said current (Im) and of said derivative (dIm/dt);
d) stopping, by a switch, circulation of the current when the length of reduced material is at least equal to a threshold value (?s).
