  1. 11. Fine Structure and semi ordered structures : Extended energy loss fine structure investigations of semi ordered materials

    Författare :Riitta Räty; Edward A Stern; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : This thesis is based on structure determinations of solid materials with Extended energy loss fine structure (EXELFS) analysis. In this method the ionisation edges of a material recorded in an electron microscope are studied. The focus is on different hard materials. LÄS MER

  3. 12. Bandit Methods for Network Optimization : Safety, Exploration, and Coordination

    Författare :Filippo Vannella; Alexandre Proutiere; Vincent Tan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The increasing complexity of modern mobile networks poses unprecedented challenges to their optimization. Mobile Network Operators (MNOs) need to control a large number of network parameters to satisfy the users’ demands. LÄS MER

  4. 13. Detailed structure features from 3D electron diffraction : Heteroatoms, framework disorders, and guest species in zeolites

    Författare :Jungyoun Cho; Xiaodong Zou; Tom Willhammar; Miguel Camblor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; zeolite; transmission electron microscope; structure determination; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : 3D electron diffraction (3D ED) has evolved as a powerful method for ab initio structure determination from sub micrometer-sized crystals. It can be used to elucidate the arrangement of atoms in crystalline materials and to provide insights into the laws of nature that govern the properties of matter. LÄS MER

  5. 14. Structure-Property Relationships of Iron N-Heterocyclic Carbene Complexes : Synthesis, Characterization and Application

    Författare :Valtýr Freyr Hlynsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoredox catalysis; photovoltaics; photosensitizer; N-heterocyclic carbene NHC ; BHAS; synthesis; Organometallic chemistry; structure-property relationship; coordination chemistry; heteroleptic iron complexes; geometry; photophysics;

    Sammanfattning : Resulting from the general availability of first-row transition metals, compared to their second- and third-row counterparts, photosensitizers (PSs) based on metals like iron have gained interest as candidates to enable photochemistry from solar energy, a largely underutilized energy source. Iron complexes equivalent to other metal complexes, currently being used as PS, do lack some of the advantageous properties required to challenge the established PSs. LÄS MER

  7. 15. Product Modularization - Coordination in the design/Manufacturing Interface

    Författare :Jan Eklind; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Product modularization; Design-Manufacturing interface; Coordination mechanisms;

    Sammanfattning : The product modularization concept has developed in different directions, since its breakthrough in the nineties. This being mainly a means to structure and divide a product into manageable units, attributes such as ‘customization tool’, ‘product development organizer’ and ‘sustainable upgrader’ characterizes the concept’s scope.
