- Two more electroplating samples were made. One with the original procedure with extra polishing; before using the same procedure all the wires were fine except one. Second sample with increasing the time instead of the current compared to the 6cm-diameter original procedure, and in addition the polishing current was increased to have a ratio of 3 w.r.t electroplating current. Will be waiting for the microscope pictures from Olga to make a decision. | - Two more electroplating samples were made.
