1. First Principles Studies on Chemical and Electronic Structures of Adsorbates
Sammanfattning : In this thesis, we focus on theoretical study of adsorbates on metal and oxide surfaces that are important for surface chemistry and catalysis. Based on first principles calculations, the adsorption ofCO, NO, NO2, C4H6S2, C22H27SH and other molecules or radicals on nobel metal surfaces (gold and silver) are investigated. LÄS MER
2. Synthesis and Characterization of Nanoprobes for X-Ray Fluorescence Computed Tomography (XFCT) Bio-imaging
Sammanfattning : X-ray fluorescence computed tomography (XFCT) is an emerging biomedical imaging technique. The KTH-XFCT laboratory system offers a characteristic 24 keV emission line, and high spatial resolution (200 ?m) images. XFCT as a newly emerging modality also requires the exploration and development of suitable contrast agents. LÄS MER
3. Photoemission and Characterization of Neutrophils and Nanoparticles : Energy Mapping and Elemental Composition with sub-µm Resolution
Sammanfattning : Imaging and visualization of cells and tissues are important when studying various biological phenomena. The ability to provide spatial information with molecular and chemical specificity may increase our insight and understanding of biological problems within life sciences. LÄS MER
4. Parameter and State Estimation with Information-rich Signals
Sammanfattning : The complexity of industrial systems and the mathematical models to describe them increases. In many cases, point sensors are no longer sufficient to provide controllers and monitoring instruments with the information necessary for operation. The need for other types of information, such as audio and video, has grown. LÄS MER
