Motion picture study of a vertical climbing film in an annular duct

Creator:: Scott, Bruce Douglas
Abstract:: This paper describes a study of two-phase gas-liquid vertical annular climbing film flow. Using a high speed Fastax movie camera, motion was slowed sufficiently to facilitate detailed analysis of the climbing film structure, based on single frame projections. The dynamic characteristics of the liquid film could likewise be obtained, though...

Investigation of low temperature solution-based deposition process for flexible electronics

Creator:: Chang, Yu-Jen
Abstract:: The critical contribution of this dissertation is to provide a better understanding of the fundamental Chemical Bath Deposition (CBD) growth kinetic and mechanism for the well known II-VI semiconductor CdS using the newly developed continuous flow microreactor. This continuous flow microreactor provides the temporal resolution to control the homogeneous reaction...

A study of climbing-film flow characteristics of various liquids and air in an annular duct

Creator:: Vierra, George Joseph
Abstract:: Momentum transfer in climbing-film flow in an annular duct was investigated. Air and various liquids, with a wide range of viscosities and surface tensions, were investigated. The two phases flowed co-currently upward, the liquid climbing as a thin film on the inner wail while the outer wall remained dry. The...

Momentum transfer in climbing-film flow in an annular duct

Creator:: Kim, Duk Hwang
Abstract:: Momentum transfer in an annular duct with upward gas-Iiquid flow was studied under the condition that the liquid flowed as a film only on the inner core of the annulus, the outer wall remaining dry. Previous workers have studied climbing and falling liquid films in tubes or on vertical planes....

Development of solution-based reaction processes for micro- and nano-structured semiconductors

Creator:: Lee, Doo-Hyoung
Abstract:: The focus of this study is to develop a general and low-cost solution-based process to fabricate micro- and nano-structured semiconductors that are suitable for electronics. This process uses simple metal halide precursors dissolved in a solvent (organic or aqueous) and is capable of forming uniform and continuous thin films via...

Iron oxidation by Thiobacillus ferrooxidans

Creator:: Kang, Sun Ki
Abstract:: The bacterium most frequently used in microbial leaching processes and studies is Thiobacillus ferrooxidans. Applications of this bacterium include the treatment of coal, low-grade ores and industrial solid wastes for the solubilization of pyrite and other trace metals associated with sulfides. The goal of this study was the development of...

Continuous flow microreactor for chemical bath deposition : a novel approach to the deposition of polycrystalline semiconductor thin films

Creator:: Mugdur, Prakash
Abstract:: Over the years, chemical bath deposition (CBD) is being widely used in the fabrication of Cu (In, Ga) Se₂ and CdTe based solar cells and photovoltaics. Many chalcogenides have been successfully deposited by this technique and it has received a great deal of attention owing to its low temperature and...

Characterizations of silicon-germanium nanocomposites fabricated by the marine diatom Nitzschia frustulum

Creator:: Liu, Shuhong
Abstract:: Marine diatoms are a class of microalgae that possess cell walls composed of silica nanoparticles. These organisms actively assimilate silicic acid Si(OH)4 from seawater, polymerize silicic acid to silica nanoparticles by a protein-mediated precipitation process, and then assemble the silica nanoparticles into intricate patterns that constitute the cell wall microarchitecture...
