  • 2 Literature Review
    2 Literature review 2.1 Thin film solid state reactions A solid state chemical reaction in the classical sense occurs when local transport of matter is observed in crystalline phases and new phases are formed.1 This definition does not mean that gaseous or liquid phases may not take part in the solid state reactions. However, it does mean that the reaction product occurs as a solid phase. Thus, the tarnishing of metals during dry or wet oxidation is also considered to be a solid state reaction. Commonly, the solid state reac- tions are heterogeneous reactions. If after reaction of two substances one or more solid product phases are formed, then a heterogeneous solid state reaction is said to have occurred. Spinel- and pyrochlore-forming reactions are well-known examples of solid-state reactions where a ternary oxide forms.5–11 In this Ph.D. thesis, heterogeneous solid state reactions are considered. Extended crystal defects as high mobility paths for atoms are essential in the reactivity of solids. Furthermore, interfaces play an important role in the solid state reactions because during hetero- geneous reactions interfaces move and mass transport occurs across them. The interfaces can be coherent, semicoherent or incoherent.28 At the interface, chemical reactions take place between species and defects; they are often associated with structural transformations and volume changes. The characteristics of thin film solid state reactions running on the nanometer scale are con- siderably different from solid state reactions proceeding in the bulk. During bulk reactions, the diffusion process is rate limiting and controls the growth.

Cyphers c 2012 Robert L. Cyphers Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science December 2012 The thesis of Robert L. Cyphers was reviewed and approved∗ by the following: Bernhard R. Tittmann Schell Professor of Engineering Science and Mechanics Thesis Advisor Clifford Lissenden Professor of Engineering Science and Mechanics Mark W. Horn Professor of Engineering Science and Mechanics Judith A. Todd Professor of Engineering Science and Mechanics // P. B. Breneman Department Head Head of the Department of Engineering Science and Mechanics ∗Signatures are on file in the Graduate School. Abstract Ultrasonic nondestructive evaluation is currently used in countless applications to maintain a system's operational integrity. Piezoelectric transducers are the devices commonly used in this field to search for defects. A sol-gel fabrication method utilizing a spray-on deposition method has proven to produce ultrasonic transducers useful in harsh environments. This procedure produces thin film transducers, which adhere directly to a substrate making it favorable in use with irregular surface geometries. These transducers operate at relatively high frequencies due to their minute thickness. The objective of this research is to investigate the ability for low frequency operation into the low kilohertz range. Depositing thicker layers of piezoelectric composites, including bismuth titanate and lead zirconate titanate, led to adhesion problems between the metal substrates and ceramic material. Delamination of the piezoelectric elements was determined to be caused by a large mismatch in thermal expansion coefficients.

  • An Investigation of the Crystal Growth of Heavy Sulfides in Supercritical
    AN ABSTRACT OF THE THESIS OF LEROY CRAWFORD LEWIS for the Ph. D. (Name) (Degree) in CHEMISTRY presented on (Major) (Date) Title: AN INVESTIGATION OF THE CRYSTAL GROWTH OF HEAVY SULFIDES IN SUPERCRITICAL HYDROGEN SULFIDE Abstract approved Redacted for privacy Dr. WilliarriIJ. Fredericks Solubility studies on the heavy metal sulfides in liquid hydrogen sulfide at room temperature were carried out using the isopiestic method. The results were compared with earlier work and with a theoretical result based on Raoult's Law. A relative order for the solubilities of sulfur and the sulfides of tin, lead, mercury, iron, zinc, antimony, arsenic, silver, and cadmium was determined and found to agree with the theoretical result. Hydrogen sulfide is a strong enough oxidizing agent to oxidize stannous sulfide to stannic sulfide in neutral or basic solution (with triethylamine added). In basic solution antimony trisulfide is oxi- dized to antimony pentasulfide. In basic solution cadmium sulfide apparently forms a bisulfide complex in which three moles of bisul- fide ion are bonded to one mole of cadmium sulfide. Measurements were made extending the range over which the volumetric properties of hydrogen sulfide have been investigated to 220 °C and 2000 atm. A virial expression in density was used to represent the data. Good agreement, over the entire range investi- gated, between the virial expressions, earlier work, and the theorem of corresponding states was found. Electrical measurements were made on supercritical hydro- gen sulfide over the density range of 10 -24 moles per liter and at temperatures from the critical temperature to 220 °C. Dielectric constant measurements were represented by a dielectric virial ex- pression.

  • Theoretical Studies on As and Sb Sulfide Molecules
    Mineral Spectroscopy: A Tribute to Roger G. Bums © The Geochemical Society, Special Publication No.5, 1996 Editors: M. D. Dyar, C. McCammon and M. W. Schaefer Theoretical studies on As and Sb sulfide molecules J. A. TOSSELL Department of Chemistry and Biochemistry University of Maryland, College Park, MD 20742, U.S.A. Abstract-Dimorphite (As4S3) and realgar and pararealgar (As4S4) occur as crystalline solids con- taining As4S3 and As4S4 molecules, respectively. Crystalline As2S3 (orpiment) has a layered structure composed of rings of AsS3 triangles, rather than one composed of discrete As4S6 molecules. When orpiment dissolves in concentrated sulfidic solutions the species produced, as characterized by IR and EXAFS, are mononuclear, e.g. ASS3H21, but solubility studies suggest trimeric species in some concentration regimes. Of the antimony sulfides only Sb2S3 (stibnite) has been characterized and its crystal structure does not contain Sb4S6 molecular units. We have used molecular quantum mechanical techniques to calculate the structures, stabilities, vibrational spectra and other properties of As S , 4 3 As4S4, As4S6, As4SIO, Sb4S3, Sb4S4, Sb4S6 and Sb4SlO (as well as S8 and P4S3, for comparison with previous calculations). The calculated structures and vibrational spectra are in good agreement with experiment (after scaling the vibrational frequencies by the standard correction factor of 0.893 for polarized split valence Hartree-Fock self-consistent-field calculations). The calculated geometry of the As4S. isomer recently characterized in pararealgar crystals also agrees well with experiment and is calculated to be about 2.9 kcal/mole less stable than the As4S4 isomer found in realgar. The calculated heats of formation of the arsenic sulfide gas-phase molecules, compared to the elemental cluster molecules As., Sb, and S8, are smaller than the experimental heats of formation for the solid arsenic sulfides, but shown the same trend with oxidation state.

  • High Temperature Ultrasonic Transducers: a Review
    sensors Review High Temperature Ultrasonic Transducers: A Review Rymantas Kazys * and Vaida Vaskeliene Ultrasound Research Institute, Kaunas University of Technology, Barsausko st. 59, LT-51368 Kaunas, Lithuania; [email protected] * Correspondence: [email protected] Abstract: There are many fields such as online monitoring of manufacturing processes, non-destructive testing in nuclear plants, or corrosion rate monitoring techniques of steel pipes in which measure- ments must be performed at elevated temperatures. For that high temperature ultrasonic transducers are necessary. In the presented paper, a literature review on the main types of such transducers, piezoelectric materials, backings, and the bonding techniques of transducers elements suitable for high temperatures, is presented. In this review, the main focus is on ultrasonic transducers with piezoelectric elements suitable for operation at temperatures higher than of the most commercially available transducers, i.e., 150 ◦C. The main types of the ultrasonic transducers that are discussed are the transducers with thin protectors, which may serve as matching layers, transducers with high temperature delay lines, wedges, and waveguide type transducers. The piezoelectric materi- als suitable for high temperature applications such as aluminum nitride, lithium niobate, gallium orthophosphate, bismuth titanate, oxyborate crystals, lead metaniobate, and other piezoceramics are analyzed. Bonding techniques used for joining of the transducer elements such as joining with glue, soldering,

Exposure Data 1.1 Chemical and physical data Arsenic is the 20th most common element in the earth’s crust, and is associated with igneous and sedimentary rocks, particularly sulfidic ores. Arsenic compounds are found in rock, soil, water and air as well as in plant and animal tissues. Although elemental arsenic is not soluble in water, arsenic salts exhibit a wide range of solubilities depending on pH and the ionic environment. Arsenic can exist in four valency states: –3, 0, +3 and +5. Under reducing conditions, the +3 valency state as arsenite (AsIII) is the dominant form; the +5 valency state as arsenate (AsV) is generally the more stable form in oxygenized environ- ments (Boyle & Jonasson, 1973; National Research Council, 1999; O’Neil, 2001; WHO, 2001). Arsenic species identified in water are listed in Table 1. Inorganic AsIII and AsV are the major arsenic species in natural water, whereas minor amounts of monomethylarsonic acid (MMA) and dimethylarsinic acid (DMA) can also be present. The trivalent mono- methylated (MMAIII) and dimethylated (DMAIII) arsenic species have been detected in lake water (Hasegawa et al., 1994, 1999). The presence of these trivalent methylated arsenical species is possibly underestimated since only few water analyses include a solvent sepa- ration step required to identify these trivalent species independently from their respective a Table 1.
