  1. 11. Characterization of Self-Assembled Monolayers of Oligo(phenyleneethynylene) Derivatives on Gold

    University dissertation from Institutionen för natur och miljö

    Author : Somsakul Watcharinyanon; Karlstads universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-assembled monolayers; Oligo phenyleneethynylene ; high-resolution X-ray photoemission spectroscopy HRXPS ; near-edge X-ray absorption fine structure spectroscopy NEXAFS ; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik; Physics; Fysik;

    Abstract : Oligo(phenyleneethynylene) (OPE) molecules are a class of fully conjugated aromatic molecules, that attract attention for their application as “molecular wires” in molecular electronic devices. In this thesis work, self-assembled monolayers (SAMs) formed from a variety of OPE derivatives have been studied. READ MORE

  2. 12. Design and synthesis of glycose-derivatives and related molecules for cell membrane mimetics

    University dissertation from Linköping : Linköpings universitet

    Author : Jing Shi; Linköpings universitet.; Linköpings universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A series of glucopyranose (α-D-glucose, β-D-glucose, D-gluconic acid and 6-amino-6-deoxy-D-glocuse) terminated alkanethiol acetals have been successfully synthesized. α and β-D-glucose were configured in controlled ways coupling with alkanethiol, in which bromosugar and trichloroacetirnidates were selected as activated glycosyl donors using different promoters tetraalkylammonium bromide (Et4NBr) and trimethylsilanetriflate (TMSOTf) respectively.

  4. 14. Surface structure and catalytic activity of Pd and Fe oxide surfaces and thin films

    University dissertation from Lund University, Faculty of Science, Department of Physics, Division of Synchrotron Radiation Research

    Author : Mikhail Shipilin; Lund University.; Lunds universitet.; [2016-10]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface X-ray diffraction SXRD ; Heterogeneous catalysis; Pd; PdO; Fe; FeO; Thin films; Fysicumarkivet A:2016:Shipilin;

    Abstract : The present work is devoted to atomic scale structural studies of the surfaces of model heterogeneous catalysts relevant to oxidation reactions. A novel approach using high-energy surface X-ray diffraction combined with mass-spectrometry measurements is employed to perform in situ structural characterization of Pd(100) and Pd(553) single crystal surfaces acting as catalysts in the process of CO oxidation under semirealistic conditions.

  5. 15. Atmospheric corrosion of copper and copper-based alloys in architecture from native surface oxides to fully developed patinas

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Tingru Chang; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Abstract : Copper and copper-based alloys are commonly used in both ancient and modern architecture. This requires an in-depth fundamental and applied understanding on their atmospheric corrosion behavior at different climatic, environmental and pollutant levels and how these parameters influence e.g. READ MORE
