The Activation of the Rare Earths by Thermal Neutrons

Description: The present knowledge of artificial radio-activity is more spotty for the rare earths than for any other region of the periodic table. The chief reason for this is the difficulty of obtaining sufficiently pure samples or at any rate such of well-known composition. Rare earthers were investigated through the activation by thermal neutrons.

Cathode Sputtering Problems

Description: The question of the nature and charge of the metallic particles emitted in cathode sputtering has been answered experimentally: the particles are primarily neutral atoms. The proof was obtained from the moving particles themselves by a new "spectroscopic method of vapor pressure measurement" in combination with a "vapor pressure measurement from coating density."

The Diffusion of the Impurity Elements in Technical Iron into Solid Iron

Description: The diffusion of carbon in solid iron has been the subject of numerous investigations over since the middle of the 19th century. Little has been published on the diffusion of the other technically important impurities present in iron. The purpose of this investigation is to help shed light on diffusion phenomena in iron. The work was performed in 1919 at the Metallurgical Institute of the Technische Hochschule in Breslin
