Diffusion bonding cycle times can be a large cost factor in the production of metal microchannel devices. The challenge is to significantly minimize this cost by reducing the bonding cycle time through rapid and uniform heating and cooling within the bonding process. Heating rates in diffusion bonding processes are typically...
East Palo Alto is a small working-class community of color in the San Francisco Bay Area. Though the community has rich agrarian roots, fertile soil, and good weather, racially-charged policies have influenced East Palo Alto’s development and significantly impacted the state of natural resources in the city in stark contrast...
An alumina microreactor was designed and fabricated to study the synthesis of nanosized silicon nitride powder via the ammonolysis of SiO vapor at temperatures ranging from 1300°C to 1400°C. It is the first high temperature ceramic microreactor capable of operating at temperatures upto 1600°C. The microreactor was designed using 3D...
Single-layer and three-layer microchannel adsorption devices were fabricated by procedure that was newly developed. Aluminum was chosen for metal housing while the adsorption pair was silica gel and water. Each adsorption layer contained two layers of 250 μm-thick silica gel. Both silica gel layers opened to the same layer of...
The primary goal of this thesis is to synthesize titanium dioxide nanorods using a continuous flow microreactor. Titania powder, one of the most important particulate materials is used for many purposes owing to its excellent optical properties of a high refractive index leading to high hiding power and whiteness of...
Cyclopropenoid fatty acids (CPFA), which are a group of
fatty acids produced by plants of the order Malvales, are known
to induce adverse physiological effects when administered to a
variety of animal species. A structurally strained cyclopropene
ring is present in all CPFA and is believed responsible for the
toxic...
Themes of authorship in Aphra Behn's Oroonoko and Daniel Defoe's Robinson Crusoe highlight locations in the stories that expose the author's concerns with their responsibilities and contributions to society. In order to frame a discussion of authorship in Oroonoko and Robinson Crusoe, it is essential to position Behn and Crusoe...
Celebrity culture is part of a long history of fame, but the modern celebrity individual came into focus in the nineteenth century. The first part of this thesis distinguishes modern celebrity – including its morality – from other types of fame, explores the intersection of celebrity and gender through the...
The Kittlitz's murrelet (Brachyramphus brevirostris) is a species of conservation concern over the entirety of its known range, which spans coastal Alaska and northeastern Russia. Concerns about the status of the species have been raised due to evidence of population declines in key breeding areas, low reproductive output, and perceived...
The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatigue, the risk for severe damage increases. Proper monitoring and inspection of bridges...
