Ferromagnetism In Some Alloys Of The Copper-Manganese-Tin System, Leonard W. Boyd Jr.
Ferromagnetism In Some Alloys Of The Copper-Manganese-Tin System, Leonard W. Boyd Jr.
Bachelors Theses and Reports, 1928 - 1970
The specific purpose of this investigation is to study the effects of heat treating at various temperatures for different lengths of time, with special attention paid to changes in magnetization. Identical heat-treating conditions were used on several different alloys, the compositions of which are such that some specimens are in the single-phase beta prime and beta regions, whereas others are in two-phase regions. For this investigation, only magnetic measurements will be attempted.

The Effect Of The Cu:Fe''' Ratio Upon The Current Efficiency In The Electrolysis Of A Copper Sulfate Solution Containing Iron Sulfate, Joseph Thomas Roy, Francis Carroll Moran
Bachelors Theses and Reports, 1928 - 1970
It is a well-known fact that, in the electrolysis of a CuSO4 solution containing iron sulfate, using insoluble anodes, with the depletion of copper, the point is finally reached where the current efficiency becomes zero. This decrease in current efficiency is due to the oxidation of the ferrous sulfate to the ferric condition at the anode, by the oxygen liberated. The resulting ferric sulfate diffuses over to the cathode and there dissolves copper from the cathode according to the chemical equation Cu + Fe2 (SO4)3 = CuSO4 + 2FeSO4. This copper, which has …
