  1. 1. Consumers, cosmetics and skin sensitizers

    Författare :Kerem Yazar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Chemical products, cosmetics and other products handled by consumers and workers frequently contain contact allergens (skin sensitizers). Contact allergens are low-molecular substances which may induce contact allergy (Type IV allergy) after contact with skin. LÄS MER

  3. 2. Photoinitiated Radical Carbonylation Using [11C]Carbon Monoxide : 11C-Labelling of Aliphatic Carboxylic Acids, Esters, and Amides

    Författare :Oleksiy Itsenko; Bengt Långström; Tor Kihlberg; Chryssostomos Chatgilialoglu; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; 11C-labelling; radicals; carbonylation; carbon monoxide; solvent effects; sensitizers; sulfoxides; WAY-100635; PET; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : One-step photoinitiated free radical carbonylation was employed for the rapid (5–7 min) labelling of aliphatic carboxylic acids, esters, and amides with a short-lived positron emitter 11C (t½ = 20.3 min) at the carbonyl position. The labelled compounds were synthesized from alkyl iodides (0.05–0. LÄS MER

  4. 3. Novel organic sensitizers and hole transport materials for efficient solid-state photovoltaic devices

    Författare :Peng Liu; Lars Kloo; Udo Bach; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic sensitizers; ssDSCs; perovskite solar cell; hole transport materials; cross-linked polymeric sulfur; Kemi; Chemistry;

    Sammanfattning : State-of-art solid-state photovoltaic devices, such as solid-state dye sensitized solar cells (ssDSSCs) and perovskite solar cells have attracted significant attention due to their high efficiency and potential low-cost manufacture. However, there are still challenges that limit the application up-scaling.. LÄS MER

  5. 4. Design, Synthesis and Properties of Organic Sensitizers for Dye Sensitized Solar Cells

    Författare :Karl Martin Karlsson; Licheng Sun; Jaejung Ko; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Acceptor; chromophore; donor; dye; sensitized; energy level; HOMO LUMO; linker; phenoxazine; sensitizer; solar cell; triphenylamine; Chemistry; Kemi; Organic synthesis; Organisk syntes;

    Sammanfattning : This thesis gives a detailed description of the design and synthesis of new organic sensitizers for Dye sensitized Solar Cells (DSCs). It is divided in 7 chapters, where the first gives an introduction to the field of DSCs and the synthesis of organic sensitizers. LÄS MER

  7. 5. GARD - Genomic Allergen Rapid Detection. A Testing Strategy for Assessment of Chemical Sensitizers

    Författare :Henrik Johansson; Institutionen för immunteknologi; []
    Nyckelord :In vitro assay. Sensitization. Predictive genomic biomarker signature.;

    Sammanfattning : The modern world is increasingly dependent of the use of chemicals. The chemical industries have greatly contributed to the high standard of living in industrialised societies, and chemical compounds surround us in everyday life. Unfortunately, a vast number of chemicals cause adverse effects on the environment and human health. LÄS MER
