  1. 11. Signal Enhancement by Dynamic Polymers in Quartz Crystal Microbalance Applications

    University dissertation from Stockholm : KTH

    Author : Gunnar Dunér; Olof Ramström; Ian Nicholls; Andra Dedinaite; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Signal enhancement; QCM; polyelectrolytes; hydrogel; iniferter; photopolymerization; dynamic polymers; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract :  This licentiate thesis presents studies of signal enhancement by dynamic polymers in quartz crystal microbalance (QCM) applications. The aim of the study has been to determine the potential for the use of polymers on QCM sensors for signal enhancement in molecular interaction studies. READ MORE

  2. 12. 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; [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.

  3. 13. 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; Inger Odnevall Wallinder; Tomas Prošek; [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

  4. 14. Synthesis of inositolphosphoglycans found in Trypanosoma cruzi and development of novel carbohydrate monomolecular layers

    University dissertation from Linköping : Linköpings universitet

    Author : Markus Hederos; Robert Madsen; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : In this thesis, synthetic carbohydrate chemistry has been utilized to contribute to the fundamental understanding of three biological relevant areas. These include parasite cell-membrane glycoconjugates, protein-resistant surfaces and antifreeze glycoproteins. READ MORE

  5. 15. Quantitative in situ analysis of initial atmospheric corrosion of copper induced by carboxylic acids

    University dissertation from Stockholm : Kemi

    Author : Harveth Gil; Christofer Leygraf; Mark Rutland; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atmospheric corrosion; carboxylic acids; copper; in situ; IRAS; QCM; coulometric reduction.; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : The interaction of carboxylic acids with copper is a phenomenon found both outdoors and, more commonly, indoors. The influence on copper of some carboxylic acids (formic, acetic, propionic, and butyric) have so far been studied at concentrations levels at least three or four orders of magnitude higher than actual indoor conditions (< 20 ppb, volume parts per billion), and with only limited emphasis on any mechanistic approach.
