    Sammanfattning : This thesis focuses on the chemical concept of conjugation, i.e., electron delocalization, and the effect it has on electronic and optical properties of molecules. LÄS MER

  3. 2. Hyperconjugation in Group 14 Organic Compounds : Design and Property Investigations

    Författare :Aleksandra Denisova; Henrik Ottosson; Thomas Müller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 1; 4-disilacyclohexa-2; 5-diene; aromaticity; computational chemistry; conjugation; cross-hyperconjugation; hyperconjugation; group 14 elements; organosilicon chemistry; silole;

    Sammanfattning : Nowadays π-conjugated molecules are widely used as materials for devices in organic and molecular electronics. This is due to the ability of such molecules to conduct electricity. However, π-conjugation leads to molecular rigidness and associated lower solubility, which limits possible applications. LÄS MER

  4. 3. Bridge Mediated Electron Transfer in Conjugated and Cross-Conjugated Donor-Acceptor Compounds

    Författare :Erik Göransson; Leif Hammarström; Hans-Christian Becker; Michael R. Wasielewski; Uppsala universitet; []

    Sammanfattning : Detailed understanding of electron transfer reactions is important in many aspects of chemistry, biology and solar energy conversion.The main aim of this thesis is to provide further insight into electron transfer through highly conjugated bridge structures. LÄS MER

  5. 4. Validation of antibodies for tissue based immunoassays

    Författare :Sandra Andersson; Anna Asplund; Fredrik Pontén; Kenneth Wester; Mike Taussig; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antibody validation; Conjugation; Estrogen receptor-beta; IHC; ISH; Lymphohematopoietic tissues; Proteomic; RNAseq; TMA; Transcriptomic; Patologi; Pathology;

    Sammanfattning : In situ protein detection in human tissues using antibodies reveals the cellular protein localization, and affinity-based proteomic studies can help to discover proteins involved in the development of diseases. However, antibodies often suffer from cross-reactivity, and the lack of positive and negative tissue controls for uncharacterized proteins complicates the mapping of the proteome. LÄS MER

  7. 5. Platelet and leukocyte activation, and platelet-leukocyte cross-talk : mechanistic aspects with special reference to diabetes mellitus

    Författare :Hu Hu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Platelet-leukocyte cross-talk modulates platelet and leukocyte function, and appears to be important in thrombosis and haemostasis. Type 1 diabetes mellitus (DM) is associated with platelet and leukocyte dysfunction and an increased risk of cardiovascular complications. LÄS MER
