  1. 16. Photoredox Catalysis Driven by Visible Light and Iron N-Heterocyclic Carbene Complexes

    Författare :Lisa de Groot; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoredox catalysis; iron N-heterocyclic carbene complexes; Fe-NHC; Visible light; ATRA; BHAS;

    Sammanfattning : Photoredox catalysis is a rapidly expanding field, in which organic transformations are catalysed using light. The most commonly used photoredox catalysts (PCs) are transition metal complexes which absorb in the visible region of the electromagnetic spectrum. LÄS MER

  3. 17. PCR inhibition mechanisms in forensic DNA analysis

    Författare :Maja Sidstedt; Teknisk mikrobiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCR inhibition mechanisms; Real-time PCR; Digital PCR; Massively parallel sequencing;

    Sammanfattning : In forensic DNA analysis, the polymerase chain reaction (PCR) enables DNAanalysis of minute biological crime scene traces. PCR is an enzymatic reaction for amplification of specific DNA fragments involving both biochemical andbiophysical processes. The main analytical challenge is posed by the nature of the samples of interest. LÄS MER

  4. 18. Analysis of thermal shock in brittle materials

    Författare :Marianne Collin; KTH; []
    Nyckelord :thermal shock; thermal stress; stress intensity; vickers indentation; alumina; silicon varbide whisker reinforced alumina;

    Sammanfattning : This thesis concerns thermal shock damage of ceramicmaterials. More specifically the work is focused on theoreticaland practical aspects of a new technique for determining thethermal shock resistance of brittle materials. LÄS MER

  5. 19. Understanding structure and function of membrane protein transporters

    Författare :Anna-Karin Lundbäck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Membrane protein transporters are important proteins in the cell, as they maintain different solutes and metabolites at a stable concentration. Numerous diseases can be linked to malfunctioning transporters, which makes them interesting pharmaceutical targets. LÄS MER

  7. 20. Exploring Novel Catalytic Chalcogenide Antioxidants

    Författare :Henrik Johansson; Lars Engman; Helena Grennberg; Troels Skrydstrup; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antioxidant; tellurium; selenium; catalytic; toxicity; ROS; neutrophil; glutathione peroxidase mimic; macrophage.; Organic chemistry; Organisk kemi; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : This thesis is concerned with the synthesis and evaluation of regenerable chalcogen containing antioxidants. Variously substituted 2,3-dihydrobenzo[b]selenophene-5-ol antioxidants were evaluated in order to gain information about structure/reactivity-relationships. LÄS MER
