An Experimental Study of the Electrodeposition of Lead
Date: June 1937
Creator: Roberts, Ira Clifford
Description: This thesis aimed to study some of the general principles underlying electrodeposition together with experimental facts regarding the effects of changing constituents of the plating solutions, variations in hydrogen-ion concentrations, and variation in current density used in the electrodeposition of lead.

Mercury-Sensitized Photochemical Action on a Mixture of Isobutane and Isobutene
Date: June 1939
Creator: Gary, Felice
Description: This study investigated mercury-sensitized photochemical action on a mixture of isobutane and isobutene. Flow runs of isobutane-isobutene 3.2.1 mercury-saturated gases illuminated with unfiltered radiation of mercury vapor lamp gave no detectable change to hydrocarbons heavier than C4 at reaction tempratures of 27C. and 99C.

Molecular Dimensions
Date: August 1938
Creator: Moss, H. H.
Description: This study attempts to calculate the areas of the cross section and diameter of the CH3 group, COOH group, the length of the carbon chain, and the longtiudinal distance between carbon atoms for each of the three acids. It also attempts to develop a method of measuring the effective diameter of molecules of gases. Equations for these terms as given by MacDougall and experiments were performed and the data applied to the equation.
