Changes in structure and stress in Mo/a-Si thin films upon annealing

Creator:: Weber, Frank John
Abstract:: The structural and stress changes in molybdenum/amorphous silicon (Mo/a-Si) EUV reflecting multilayers during annealing at 316°C were studied. The amorphous interlayers, with an Mo:Si stoichiometry of 1:2, grew during annealing. The residual stresses in each component of the multilayer also changed significantly. Through high resolution electron microscopy, selected area electron...

Flavor comparison of ultra high temperature processed milk heated by Ohmic heating and conventional methods

Creator:: He, Juan
Abstract:: Ultra high temperature (UHT) processing can extend shelf life of milk to several months without refrigeration, which is more convenient and energy saving than pasteurized milk. However, the poor acceptance caused by "cooked" flavors limits its marketing growth, especially in United States. Ohmic heating, which has a more uniform and...

Heat treatment effects on CPM-M4 tool steel performance as edged blade material

Creator:: Lian, Sidi
Abstract:: CPM-M4 tool steel is a commonly used knife blade material due to its high strength and wear resistance. The goal of this thesis is to understand how heat treatment parameters affect blade performance and microstructure.Five heat treatments were applied to CPM-M4 steel by varying austenitizing and tempering temperatures. The microstructures...

A thermal hydraulics analysis of a molybdenum production element for implementation in TRIGA reactors

Creator:: Byfield, Patrick
Abstract:: The metastable isotope of technetium-99 (Tc-99m) is an important diagnostic tool used in the field of nuclear medicine due to the isotope's 6.0 hour half-life, 140.5 keV γ-decay mechanism, and multiple oxidation states [1,2]. Approximately 70% of the world’s nuclear medicine procedures involve the use of Tc-99m [3]. The conventional...
