Graduate Theses & Non-Theses
Generating gold nanoparticles (AuNPs) from gold chloride solution by precipitating with compounds can be difficult due to the potentially required high temperatures. Tin chloride can be used to overcome this dilemma. The process that is known to make Purple of Cassius is a method where gold chloride and tin chloride solutions are mixed to form AuNPs and tin oxide precipitate. However, it is modified by adding hydrazine to resolubilize the tin oxide and provide a more stable solution for the AuNPs. A three-factor central composite experimentally designed model was created using Design Expert incorporating pH, temperature, and gold concentration as …

Some Early Geologists And Their Work In Montana, John E. Blixt
Bachelors Theses and Reports, 1928 - 1970
This paper marks an increased refinement and more detailed accuracy in the description of the geological features of the state. It includes the recent studies of mineral deposits, of oil structures, of the formations of bedded rocks and their included fossils, carried on both by the Federal and State governments and by various interested private persons, such as the mining companies. It is within this period that the Federal Government encouraged the U. S. Geological Survey in the publication of monographs on the National Parks, papers of great popular interest and educational value making these beautiful regions comprehensible in their …
