  2. 1. Surface Plasmon Resonance : Sensitivity and Resolution

    Author : Knut Johansen; Günter Gauglitz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Surface plasmon resonance (SPR) is a frequently used technique for detection of biomolecular interactions at surfaces. The SPR phenomenon emanates from an electromagnetic surface wave that is exited by a light source. READ MORE

  4. 2. Sensitivity and Uncertainty Analysis Methods : with Applications to a Road Traffic Emission Model

    Author : Olle Eriksson; Stig Danielsson; Rolf Sundberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Emission; Grid; Model; Pollutant; Response surface; Road traffic; Sensitivity analysis; Simulation; Uncertainty analysis; Avgaser; Vägtrafik; Miljöaspekter; Statistics; Statistik;

    Abstract : There is always a need to study the properties of complex input–output systems, properties that may be very difficult to determine. Two such properties are the output’s sensitivity to changes in the inputs and the output’s uncertainty if the inputs are uncertain. READ MORE

  5. 3. Interfacial Properties of Biomacromolecular Model Systems: Surface Forces and Nanotribology

    Author : Niklas Nordgren; Mark Rutland; Harry Brumer III; Robert Pelton; KTH; []

    Abstract : The nanotribology, adhesion and related interfacial properties of biomacromolecular systems have been studied.  The aim was to elucidate the role of physisorbed and chemically grafted bio-polymers implicated as mediators for cellulose based processing and material design. READ MORE

  6. 4. Rare-gas Clusters Studied by Electron Spectroscopy : Structure of Heterogeneous Clusters and Effects of Electron Scattering on Auger Decay

    Author : Marcus Lundwall; Olle Björneholm; Gunnar Öhrwall; Maxim Tchaplyguine; Thomas Möller; Uppsala universitet; []
    Keywords : Physics; Nano-particles; Clusters; Heterogeneous clusters; Core-shell clusters; XPS; UPS; AES; Electron scattering; Radial structure; Surface structure; Surface sensitivity; Synchrotron radiation; Ne; Ar; Kr; Xe; Fysik;

    Abstract : In this Thesis experimental studies of nano-clusters using synchrotron radiation based photoelectron (UPS and XPS) and Auger Electron Spectroscopy (AES) are presented. The investigations may be divided into two parts where the first reports on the structure of heterogeneous two component clusters, and the second concerns electronic decay processes. READ MORE

    Abstract : Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. READ MORE
