Doctoral Dissertations. 1089. https://scholars.unh.edu/dissertation/1089 This Dissertation is brought to you for free and open access by the Student Scholarship at University of New Hampshire Scholars' Repository. It has been accepted for inclusion in Doctoral Dissertations by an authorized administrator of University of New Hampshire Scholars' Repository. For more information, please contact [email protected]. INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target” for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5. PLEASE NOTE: Some pages may have indistinct print. Filmed as received.

  • Recent Advances in Microwave-Assisted Copper-Catalyzed Cross-Coupling Reactions
    catalysts Review Recent Advances in Microwave-Assisted Copper-Catalyzed Cross-Coupling Reactions Younis Baqi Department of Chemistry, College of Science, Sultan Qaboos University, P.O. Box 36, Muscat 123, Oman; [email protected]; Tel.: +968-2414-1473 Abstract: Cross-coupling reactions furnishing carbon–carbon (C–C) and carbon–heteroatom (C–X) bond is one of the most challenging tasks in organic syntheses. The early developed reaction protocols by Ullmann, Ullman–Goldberg, Cadiot–Chodkiewicz, Castro–Stephens, and Corey–House, utilizing elemental copper or its salts as catalyst have, for decades, attracted and inspired scientists. However, these reactions were suffering from the range of functional groups tolerated as well as severely restricted by the harsh reaction conditions often required high temperatures (150–200 ◦C) for extended reaction time. Enormous efforts have been paid to develop and achieve more sustainable reaction conditions by applying the microwave irradiation. The use of controlled microwave heating dramatically reduces the time required and therefore resulting in increase in the yield as well as the efficiency of the reaction. This review is mainly focuses on the recent advances and applications of copper catalyzed cross-coupling generation of carbon–carbon and carbon–heteroatom bond under microwave technology. Keywords: cross-coupling reaction; Cu catalyst; microwave irradiation; methodology; synthesis 1. Introduction Carbon–carbon (C–C) and carbon–heteroatom (C–X) bond formations through cross- Citation: Baqi, Y. Recent Advances in coupling reactions represents as one of the most useful strategy in the synthetic organic Microwave-Assisted chemistry, hence many procedures and methodologies have been developed and published Copper-Catalyzed Cross-Coupling in the literature.

It is a ductile metal with very high thermal and electrical conductivity. Pure copper is rather soft and malleable and a freshly - exposed surface has a pinkish or peachy color. It is used as a thermal conductor, an electrical conductor, a building material, and a constituent of various metal alloys. Copper metal and alloys have been used for thousands of years. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as Cyprium, "metal of Cyprus", later shortened to Cuprum.

  • Synthesis and Structural Characterization of Semiconductors Based on Kesterites
    Synthesis and Structural Characterization of Semiconductors based on Kesterites vorgelegt von Anna Ritscher, Bakk.rer.nat M.Sc. aus Villach, Österreich von der Fakultät II - Mathematik und Naturwissenschaften der Technischen Universität Berlin zur Erlangung des akademischen Grades Doktorin der Naturwissenschaften - Dr.rer.nat. - genehmigte Dissertation Promotionsausschuss: Vorsitzende: Prof. Dr. Regine von Klitzing Gutachter: Prof. Dr. Martin Lerch Gutachter: Prof. Dr. Manfred Mühlberg Tag der wissenschaftlichen Aussprache: 28.10.2016 Berlin, 2016 “There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory mentioned, which states that this has already happened.” Douglas Adams, The Hitchhiker’s Guide to the Galaxy Abstract The here-presented thesis provides detailed investigations on the structural characteris- tics of the chalcogenide Cu2ZnSnS4 (CZTS). This semiconductor material is a promising candidate for absorber layers in solar cells due to its desirable properties for thin film photovoltaic applications. Yet, compared to current used chalcopyrite-based devices, effi- ciencies are significantly lower. This could be attributed to structural effects. Fundamental understanding of the structural characteristics of potential thin film absorber compounds is crucial for proper materials design in the field of solar technology. Therefore, intensive research is necessary to obtain knowledge on so far unexplored structural features or to certify and extend current literature data. The main objective of the here-presented work was to deepen the understanding of the quaternary sulfide 2Cu ZnSnS4. Primary, this implied the full characterization of structural properties of the compound using various diffraction techniques.

With respect to their oxide homologues, however, they are characterised by noticeably different chemical, structural and hence functional features. Their potential applications span several fields, and in many of the foreseen applications (e.g., in bioimaging and related fields), the achievement of stable colloidal suspensions of metal sulphides is highly desirable or either an unavoidable requirement to be met. To this aim, robust functionalisation strategies should be devised, which however are, with respect to metal or metal oxides colloids, much more challenging. This has to be ascribed, inter alia, also to the still limited knowledge of the sulphides surface chemistry, particularly when comparing it to the better established, though multifaceted, oxide surface chemistry.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Ni(II) dithiocarbamate complexes have been synthesized and characterized by UV-Vis, FTIR, and NMR spectroscopic techniques. Electronic spectra measurements indicate that the complexes are four-coordinate square planar geometry while the FTIR confirmed that the dithiocarbamates act as bidentate chelating ligands. The compounds were used as single source precursors and thermolysed ∘ at 220 C to prepare HDA-capped NiS nanocrystals which were characterized by absorption and photoluminescence (PL) spectra measurements, powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). Absorption spectra studies showed that the synthesized NiS nanoparticles are blue- shifted relative to the bulk material and PL studies showed emission maxima that are red-shifted compared to the absorption band edges. The XRD patterns of the as-prepared NiS nanoparticles revealed cubic crystalline phases.

The packing diagram of these ILs and the interaction between the cations and the anions have been investigated by single-crystal X-ray diffraction. The single crystal analysis shows that all crystal structures are stabilized by several non- classical hydrogen bonding, and all ILs based on the same chain pyridinium cation are isostructural. The ILs based on short chain cation are monoclinic and crystallize in the space group P21/n, while the crystals of the ILs based on long chain cation are triclinic and form in the space group P1̅.

Cu(CH3COO)2 H2O and Na2S2O3 5H2O. In this reaction the influence of the following factors was pursued: pH value, reaction time, molar ratios, temperature and others. In this article we tried to establish the evolution of the morphology and the shape of the CuS nanocrystallites with the pH value. The CuS nanocrystallites obtained were studied by X ray diffraction, IR spectrometry, TEM – transmission electron microscopy and SAED selected area electron diffraction. The CuS crystallites are formed in spherical or “discoidal” particles which are bonded in bigger aggregates. The reaction pH value was varied from a slightly acid value to an alkali value. In case of alkali medium the crystallites dimensions were smaller than their value in slightly acid medium.
