Preparation of Metallic Titanium by Film Boiling
From abstract: The Van Arkel-deBoer method for producing ductile titanium by thermal decomposition of TiI4 vapor and deposition on an electrically heated filament is modified by film boiling TiI4 liquid on a heated filament, resulting in similar titanium deposition on the filament and liberation of iodine to the gaseous phase."

Some Chemical Properties of Curium
Report discussing details of curium's chemical properties, including gamma radiation, solubility, and absorption. A procedure for separating curium from americium and the preparation of terbium tetrafluoride, which lead to its discovery, is also included.

STUDIES IN THE NUCLEAR CHEMISTRY OF PLUTONIUM, AMERICIUM, AND CURIUM AND MASSES OF THE HEAVIEST ELEMENTS
Ion exchange column elution methods for the separation of americium and curium using tartrate and lactate solutions have been developed which are superior to citrate elutions. Tartrate elutions are suitable for slow separations and lactate elutions are satisfactory for general use where rapid separations are required. Fission and spallation products were isolated from Pu{sup 239} targets which had been bombarded with alpha particles of 21 to 37 Mev energy. Fission yield curves as well as fission and spallation excitation functions are presented and discussed in terms of odd-even and Z{sup 2}/A effects. The high cross sections observed for the (a, 2n) and (a, p2n) reactions were surprising results from this investigation. In the course of the Pu{sup 239} bombardments, studies of the decay schemes of Am{sup 240}, Cm{sup 240}, and Cm{sup 241} were undertaken. Decay energy and half-1ife information on all of the transmercury nuclides has been collected and systematized. Trends on the energy surface for alpha energies, beta energies, nucleon binding energies, and Bohr-Wheeler parameters are presented. These energy systematics have led to a complete tabulation of the masses of the isotopes of the elements above mercury. Predictions of nuclear properties are included for some isotopes of elements 99 …
