  • Manganese Toxicity May Appear Slowly Over Months and Years
    MANGANESE 11 2. RELEVANCE TO PUBLIC HEALTH 2.1 BACKGROUND AND ENVIRONMENTAL EXPOSURES TO MANGANESE IN THE UNITED STATES Manganese is a naturally occurring element and an essential nutrient. Comprising approximately 0.1% of the earth’s crust, it is the twelfth most abundant element and the fifth most abundant metal. Manganese does not exist in nature as an elemental form, but is found mainly as oxides, carbonates, and silicates in over 100 minerals with pyrolusite (manganese dioxide) as the most common naturally-occurring form. As an essential nutrient, several enzyme systems have been reported to interact with or depend on manganese for their catalytic or regulatory function. As such, manganese is required for the formation of healthy cartilage and bone and the urea cycle; it aids in the maintenance of mitochondria and the production of glucose. It also plays a key role in wound-healing. Manganese exists in both inorganic and organic forms. An essential ingredient in steel, inorganic manganese is also used in the production of dry-cell batteries, glass and fireworks, in chemical manufacturing, in the leather and textile industries and as a fertilizer. The inorganic pigment known as manganese violet (manganese ammonium pyrophosphate complex) has nearly ubiquitous use in cosmetics and is also found in certain paints. Organic forms of manganese are used as fungicides, fuel-oil additives, smoke inhibitors, an anti-knock additive in gasoline, and a medical imaging agent. The average manganese soil concentrations in the United States is 40–900 mg/kg; the primary natural source of the manganese is the erosion of crustal rock.

This transformation has not previously been done catalytically and has not been done in practical manner with stepwise or stoichiometric processes. Building on the previous work of the Lambert lab on the metathesis of cyclopropene and an aldehyde using a hydrazine catalyst, this work discusses efforts to expand to the less stained norbornene. Computational and experimental studies on the catalytic cycle are discussed, including detailed experimental work on how various factors affect the difficult cycloreversion step. The second portion of this thesis details the use of chiral cyclopropenimine bases as catalysts for asymmetric Michael reactions. The Lambert lab has previously developed chiral cyclopropenimine bases for glycine imine nucleophiles. The scope of these catalysts was expanded to include glycine imine derivatives in which the nitrogen atom was replaced with a carbon atom, and to include imines derived from other amino acids. i Table of Contents List of Abbreviations…………………………………………………………………………..iv Part I: Carbonyl-Olefin Metathesis…………………………………………………………… 1 Chapter 1 – Metathesis Reactions of Double Bonds………………………………………….. 1 Introduction………………………………………………………………………………. 1 Olefin Metathesis………………………………………………………………………… 2 Wittig Reaction…………………………………………………………………………... 6 Tebbe Olefination………………………………………………………………………... 9 Carbonyl-Olefin Metathesis…………………………………………………………….

  • Atomic Order in Non-Equilibrium Silicon-Germanium-Tin Semiconductors
    Atomic Order in Non-Equilibrium Silicon-Germanium-Tin Semiconductors S. Mukherjee1, N. Kodali1, D. Isheim2, S. Wirths3, J. M. Hartmann4, D. Buca3, D. N. Seidman2, and O. Moutanabbir1,* 1 Department of Engineering Physics, École Polytechnique de Montréal, Montréal, C. P. 6079, Succ.

The precise knowledge of the atomic order in monocrystalline alloys is fundamental to understand and predict their physical properties. With this perspective, we utilized laser-assisted atom probe tomography to investigate the three-dimensional distribution of atoms in non-equilibrium epitaxial Sn-rich group IV SiGeSn ternary semiconductors. Different atom probe statistical analysis tools including frequency distribution analysis, partial radial distribution functions, and nearest neighbor analysis were employed in order to evaluate and compare the behavior of the three elements to their spatial distributions in an ideal solid solution. This atomistic-level analysis provided clear evidence of an unexpected repulsive interaction between Sn and Si leading to the deviation of Si atoms from the theoretical random distribution. This departure from an ideal solid solution is supported by first principal calculations and attributed to the tendency of the system to reduce its mixing enthalpy throughout the layer-by-layer growth process. PACS: 68.35 bd, 38.35 bg, 34.20 Gj, 68.35 Dv 1 The assumption that the arrangement of atoms within the crystal lattice is perfectly random is a broadly used approximation to establish the physical properties of semiconductor alloys.

  • Conformational Studies of Aliphatic Secondary Ozonides (Propene, 1-Butene and 1-Heptene) by Means of FTIR Spectroscopy
    DOI: 10.2478/s11532-006-0031-3 Research article CEJC 4(4) 2006 578–591 Conformational studies of aliphatic secondary ozonides (propene, 1-butene and 1-heptene) by means of FTIR spectroscopy Ruta Bariseviciute, Justinas Ceponkus, Alytis Gruodis, Valdas Sablinskas∗ Department of General Physics and Spectroscopy, Vilnius University, Vilnius-01513, Lithuania Received 6 January 2006; accepted 31 May 2006 Abstract: Ozonization reaction of simple alkenes was studied by means of FT infrared absorption gas spectroscopy. The reaction was performed at 95 K in neat films of the reactants. IR absorption spectra of the gaseous products were recorded. The spectra were analyzed combining experimental results with theoretical calculations performed at B3LYP 6-311++G (3df, 3pd) level. We found that among all theoretically predicted conformers of propene secondary ozonide, only one which has the O-O half-chair configuration for the five membered ring and the radical attached in the equatorial position was present in the sample. Samples of 1-butene and 1-heptene secondary ozonides consist from two conformers of very similar energy (ΔH =0.3 kJ/mol). The most stable conformer for both ozonides is the one with O-O half-chair configuration of the five membered ring and the radical attached in equatorial position and the aliphatic chain in gauche position. The second stable conformer has the aliphatic chain in anti position. c Versita Warsaw and Springer-Verlag Berlin Heidelberg. All rights reserved.
