Heat integrated distillation has been studied using an experimental
column built for that purpose. Heat integration involves the
use of intermediate reboilers and condensers to increase the thermal
efficiency of distillation. The intermediate reboiler and condenser
systems used in this work were designed so that the experimental
column could be...
Platinum and palladium surfaces are utilized as catalytic surfaces in the chemical industry. Understanding how hydrogen atoms interact with the metal surfaces will allow for further advancement in this area. Specifically, the interaction of hydrogen on the surface and subsurface of these metals was investigated using density functional theory calculations...
Governments have employed special capital gains taxes to curb speculation in real estate and raise public revenue. Economic theory suggests that the introduction of a gains tax with a declining rate structure over time will induce prospective buyers to reduce their demand for land and will induce sellers to offer...
Amorphous metal thin films (AMTFs) are of growing interest due to their unique mechanical properties and chemical stability. AMTFs have an advantage over polycrystalline metal films due to the lack of grain boundaries which gives AMTFs added durability and relatively smoother surfaces. For this reason, AMTFs have been investigated as...
Advances in energy technologies and electronics have typically occurred through either heightened performance or cost reduction. This dissertation explores both routes through a series of fundamental material studies that may contribute to the enabling of next generation devices. Solution based syntheses and deposition of chemical products offer a low cost...
The reactions of EGTA, [ethylene bis (oxyethylenenitrilo)]
tetraacetic acid, with 51 metal ions have been studied spectrophotometrically in aqueous solutions.
The absorption spectra of the
chelates formed were measured with a recording spectrophotometer
between 200 and 700 mμ. The pH of each solution was varied and a
spectrum was scanned...
Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
Physics problems that require integration, such as finding the center of mass of an object or finding the electric field from a continuous distribution of charge, are one type of problem that is difficult for introductory physics students to solve. These problems require students to define a coordinate system in...
Remnants of railroad logging camps, and their associated features, are perhaps some of the most common archaeological resources found on public lands in the Pacific Northwest. Many camps have already been located, their cultural materials inventoried, and networks of logging railroad grades mapped. Yet, despite these efforts, little can be...
