  1. 1. Organic Electronics and Microphysiological Systems to Interface, Monitor, and Model Biology

    Författare :Sebastian Buchmann; Anna Herland; Erica Zeglio; Agneta Richter-Dahlfors; Maria Asplund; KTH; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organic bioelectronics; organic electrochemical transistors; conjugated polymers; microphysiological systems; in vitro cell models; Organisk bioelektronik; organiska elektrokemiska transistorer; Konjugerade polymerer; Mikrofysiologiska system; in vitro-modeller; Medicinsk teknologi; Medical Technology;

    Sammanfattning : Biological processes in the human body are regulated through complex and precise arrangements of cell structures and their interactions. In vivo models serve as the most accurate choice for biological studies to understand these processes. However, they are costly, time-consuming, and raise ethical issues. LÄS MER

  3. 2. Organic Heavy Group 14 Element Compounds : A Study of Their Chemical Bonding Properties Directed Towards Applications as Molecular Wires and in Synthesis

    Författare :Julius Tibbelin; Henrik Ottosson; Christoph Marschner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silicon; Group 14 Elements; Silenes; Conjugation; Chemical Bonding; Electronic Structure; Protecting Group Chemistry; Physical organic chemistry; Fysikalisk organisk kemi; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : The research described herein includes synthesis, spectroscopy, and quantum chemical calculations with focus on the characteristic properties of compounds with bonds between carbon and the heavier Group 14 elements.The chapters based on the first four papers concern σ- and σ/π-conjugated compounds, although the focus of the first paper is on ring strain of bicyclo[1.

  4. 3. Upscaling Organic Electronic Devices

    Författare :Abdellah Malti; Xavier Crispin; Ananth Dodabalapur; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Conventional electronics based on silicon, germanium, or compounds of gallium require prohibitively expensive investments. A state-of-the-art microprocessor fabrication facility can cost up to $15 billion while using environmentally hazardous processes. LÄS MER

  5. 4. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

    Författare :Daniel Hagberg; Licheng Sun; Olof Ramström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chromophores; Dye Sensitized Solar Cells; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis is divided into four parts with organic chromophores for dye sensitized solar cells as the common feature and an introduction with general concepts of the dye sensitized solar cells. The first part of the thesis describes the development of an efficient organic chromophore for dye sensitized solar cells. LÄS MER
