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...

Fiber Bragg grating-tunable diode laser

Creator:: Ericksen, Doug
Abstract:: Continuously tunable diode laser sources coupled to single-mode fiber are useful sources for fiber Bragg grating (FBG) strain sensors. This paper describes the development and fabrication of such a device. An introduction is given describing applications of tunable lasers and some of the different methods of creating a tunable diode...

Low cost, short wavelenght fiber Bragg grating strain sensor systems

Creator:: Vaughan, Lira
Abstract:: Fiber Bragg grating sensors have been constantly researched for the last ten years and have finally begun to find use in the commercial market. However, one of the major factors limiting their widespread use is their system cost. Their lightweight, flexibility, electromagnetic immunity, and small size make fiber Bragg grating...

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...

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...

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...

The construction and computational modeling of a fiber Bragg grating tunable laser diode

Creator:: Winz, Michele W.
Abstract:: The widespread adoption of wavelength division multiplexing to increase the bandwidth of optical fiber communication systems has provided a major impetus for research on low cost, single-mode, wavelength stable tunable diode lasers for use in optical telecommunications due to the large volume of lasers required. Other applications, such as demodulation...

The fabrication of fiber Bragg gratings

Creator:: Stump, Kurt
Abstract:: Fiber Bragg gratings have become an important element in the fields of telecommunications and fiber optical sensing. Their small size, light weight and high tunability have made them ideal for many unique applications. In this paper the fabrication of these devices is investigated. Following a review of current literature and...

Alternating-current thin-film electroluminescent device optical excitation experiments

Creator:: Cleary, Bradford A.
Abstract:: This thesis investigates two methods of optical excitation of alternating-current thin-film electroluminescent (ACTFEL) devices. The two experimental methods investigated in this thesis are the photo-induced charge (PIQ) and luminescence (PIL), and the subthreshold-voltage induced transferred charge (VIQ) techniques. PIQ/PIL experiments utilize an above-bandgap laser pulse to investigate the transport properties...

Antisense down-regulation of 4CL expression alters lignification, tree growth and saccharification potential of field-grown poplar

Creator:: Voelker, Steven L., Lachenbruch, Barbara, Meinzer, Frederick C., Jourdes, Michael, Ki, Chanyoung, Patten, Ann M., Davin, Laurence B., Lewis, Norman G., Tuskan, Gerald A., Gunter, Lee, Decker, Stephen R., Selig, Michael J., Sykes, Robert, Himmel, Michael E., Kitin, Peter, Shevchenko, Olga, and Strauss, Steven H.
Abstract:: Transgenic down-regulation of the Pt4CL1 gene family encoding 4-coumarate:coenzyme A ligase (4CL) has been reported as a means for reducing lignin content in cell walls and increasing overall growth rates, thereby improving feedstock quality for paper and bioethanol production. Using hybrid poplar (Populus tremula 3 Populus alba), we applied this...
