    Abstract: At the suggestion of H.A. Lorentz, Michelson’s famous experiment of 1881 was repeated in 1887 because of an alleged error pointed out by Potier. By overlooking a minor omission when compounding the newer data, the suggested correction did not materially change the original conclusion, namely, that light was propagated with constant speed (c) irresp...

    Abstract: The influence of plating mode, chloride ion on morphology of copper deposits has been studied on pure copper substrate. The electroplating was conducted at 50mA/〖cm〗^2 , 25°C in cupric sulfate-sulfuric acid bath with various chloride additions 0.001-0.01 ml. The morphology and grain sizes of the electrodeposited copper were examined by atomic force... Show More
