Metabolic engineering of Shewanella oneidensis MR-1 for microbial fuel cell application

Creator:: Hall, Robert G. (Robert George)
Abstract:: Shewanella oneidensis MR-1 is a gram-negative, facultative anaerobic bacteria with the capability of dissimilatory metal reduction. The ability of the organism to reduce a wide range of solid metal-oxides during anaerobic respiration makes it an ideal candidate for the powering of microbial fuel cells (MFCs), which capture the electrons discharged...

Distributed temperature sensing with neodymium-doped optical fiber

Creator:: Lounsbury, Jimson S.
Abstract:: Polymer electrolyte membrane (PEM) fuel cells are being studied for use as high efficiency power plants in alternative fuel vehicles. To maintain high efficiency the operating temperatures of the membranes in these fuel cells must be closely monitored and controlled. However, the environment inside of the fuel cell is not...

Fabrication and characterization of thin-film electromagnetic coils and heaters for microchannel applications

Creator:: Dehuff, Nicole L.
Abstract:: The focus of this thesis involves developing general fabrication processes relevant to the manufacture of two new devices for the Microscale technology Energy and Chemical Systems (MECS) program at Oregon State University. The two MECS devices developed, capture dots and transparent thin-film heaters (TTFHs), require unique process development for successful...

Fabrication and characterization of p-type CuO / n-type ZnO heterostructure gas sensors prepared by sol-gel processing techniques

Creator:: Ravichandran, Ram
Abstract:: Increased interest in the field of sensor technology stems from the availability of an inexpensive and robust sensor to detect and quantify the presence of a specific gas. Bulk p-CuO/n-ZnO heterocontact based gas sensors have been shown to exhibit the necessary sensitivity and selectivity characteristics, however, low interfacial CuO/ZnO contact...

Deep ultraviolet solid-state laser development

Creator:: Dutton, David A. (David Adam)
Abstract:: There is a new possibility of generating deep ultraviolet laser radiation from a solid-state source. With recent advances in material development, a new nonlinear optical crystal provides a greater damage threshold than current materials making higher conversion efficiencies possible. This thesis examines the possibility of using this crystal to generate...

Grating-tuned external cavity diode lasers

Creator:: Falconer, Beate Stephan
Abstract:: Diode lasers have many advantages such as small size, high efficiency and small angular dispersion of the collimated beam. However they also have some problems like lack of frequency stability. They can not be tuned in wavelength. An external cavity can solve these problems and decrease the laser linewidth. To...

Electro-optic characterization of SrS-based alternating current thin-film electroluminescent devices

Creator:: Nevers, Corey A.
Abstract:: Two methods of electro-optically characterizing alternating-current thin-film electroluminescent (ACTFEL) devices are investigated: photo-induced transferred charge (PIQ) and luminescence (PIL), and subthreshold voltage-induced transferred charge (VIQ) techniques. Both techniques provide information related to traps within the phosphor layer. PIQ/PIL experiments monitor the transport of electrons and holes across the phosphor layer...

Techniques and media for excised tip culture of Vinifera cultivars

Creator:: Subhanij, Thiravira
Abstract:: Excised apical stem tips (2-5 mm) of grape cultivars grew well on Murashige and Skoog's (1962) medium for tobacco callus. Additions of glycine were not essential but gave a slight stimulus to growth. Naphthalene acetic acid slightly reduced growth rates but reductions were not statistically significant. Kinetin and coconut milk...
