Temperature Dependent Behavior of Optical Loss from Hydrogen Species in Optical Fibers at High Temperature
Temperature Dependent Behavior of Optical Loss from Hydrogen Species in Optical Fibers at High Temperature Elizabeth Ann Bonnell Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science In Materials Science and Engineering Gary R. Pickrell, Chair Daniel S. Homa Christopher R. Winkler 7 April 2015 Blacksburg, VA Keywords: Hydrogen, Fiber Optics, OH Species, Temperature Dependence, Glass Structure, Infrared Spectroscopy, Diffusion Temperature Dependent Behavior of Optical Loss from Hydrogen Species in Optical Fibers at High Temperature Elizabeth Ann Bonnell ABSTRACT This study reports on the behavior of silica based optical fibers in a hydrogen environment at high temperatures. The hydrogen response in the form of optical loss in the wavelength range of 1000- 2500 nm of a germanium doped graded index 50/125 graded index fiber was examined in the temperature range of 20–800 °C. When the fiber was exposed to hydrogen at 800 °C two absorption bands appeared: ~1390 nm assigned to the first overtone of the hydroxyl stretch and ~2200 nm band with complex assignments including the combination mode of the fundamental hydroxyl stretch with SiO4 tetrahedral vibrations and the combination mode of SiOH bend and stretch. The growth rate of the 1390 nm band fits the solution to the diffusion equation in cylindrical coordinates while the 2200 nm band does not. Absorption for both bands persisted as the fiber is cooled to room temperature. Temperature dependent behavior was observed in that as temperature increases from room temperature, the absorption intensity decreases and band shifts slightly to longer wavelengths. -

Patterned Thin Film Cathodes for Micro-Solid Oxide Fuel Cells
PATTERNED THIN FILM CATHODES FOR MICRO-SOLID OXIDE FUEL CELLS Presented by: NEIL JONATHAN SIMRICK A thesis submitted for the degree of Doctor of Philosophy of the University of London and for the Diploma of Imperial College The Department of Materials Imperial College London, Prince Consort Road, London SW7 2BP 2010 Abstract The miniaturisation of Solid Oxide Fuel Cells (SOFCs) to micro (u)-SOFCs in recent years has led to the implementation of metallic and ceramic thin film membranes less than one micron thick for cell components such as anodes, cathodes, electrolytes and current collectors. Electrochemical processes (particularly the oxygen reduction reaction) occurring at the SOFC cathode are regarded as the primary inhibitor to cell performance. The reduction in operating temperature to less than 600°C for portable device applications reduces the reaction kinetics further. Silver (Ag) was used as a potential low-temperature cathode material for R-SOFCs in this work due to its known oxygen permeability and high electrical conductivity. Ag films approximately 100 nm thick were thermally unstable at temperatures as low as 250°C. A dewetting process occurred via the surface self diffusion of Ag to uncover the substrate and reduce the overall energy of the system. The oxygen reduction reaction occurring at lanthanum strontium cobalt iron oxide (La0.6Sr0.4C00.2Fe0.803.8 or LSCF) SOFC cathodes was investigated using patterned LSCF thin films. LSCF was deposited via pulsed laser deposition and photolithographically patterned to produce geometrically well-defined micro- cathodes. The electrical conductivity of as-deposited and etched LSCF thin films was determined. A maximum conductivity of 5700 Snil was measured in air, however degradation in performance occurred upon the temperature cycling of LSCF films subjected to a photolithography and etching process. -
Applications of Graphene and Its Derivatives in the Upstream Oil and Gas Industry: a Systematic Review
nanomaterials Review Applications of Graphene and Its Derivatives in the Upstream Oil and Gas Industry: A Systematic Review Lipei Fu, Kaili Liao *, Bo Tang, Lujun Jiang and Weiqiu Huang * School of Petroleum Engineering, ChangZhou University, Changzhou 213164, China; [email protected] (L.F.); [email protected] (B.T.); [email protected] (L.J.) * Correspondence: [email protected] (K.L.); [email protected] (W.H.) Received: 9 April 2020; Accepted: 23 May 2020; Published: 26 May 2020 Abstract: Graphene and its derivatives, with their unique two-dimensional structures and excellent physical and chemical properties, have been an international research hotspot both in the research community and industry. However, in application-oriented research in the oil and gas industry they have only drawn attention in the past several years. Their excellent optical, electrical, thermal and mechanical performance make them great candidates for use in oil and gas exploration, drilling, production, and transportation. Combined with the actual requirements for well working fluids, chemical enhanced oil recovery, heavy oil recovery, profile control and water shutoff, tracers, oily wastewater treatment, pipeline corrosion prevention treatment, and tools and apparatus, etc., this paper introduces the behavior in water and toxicity to organisms of graphene and its derivatives in detail, and comprehensively reviews the research progress of graphene materials in the upstream oil and gas industry. Based on this, suggestions were put forward for the future research. This work is useful to the in-depth mechanism research and application scope broadening research in the upstream oil and gas industry. Keywords: graphene and its derivatives; upstream oil and gas industry; enhanced oil recovery; well working fluid; profile control and water shutoff; oily wastewater treatment 1. -
