    Author : Sebastian Buchmann; Anna Herland; Erica Zeglio; Agneta Richter-Dahlfors; Maria Asplund; KTH; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 12. An Organic Electrochemical Transistor for Printed Sensors and Logic

    Author : David Nilsson; Magnus Berggren; George G. Malliaras; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; printable organic electrochemical transistors OECT ; polymers; charge signal carriers; proton-conducting electrolyte Nafion ; Organic chemistry; Organisk kemi;

    Abstract : Conducting polymers entered the research field in late 70´s and efforts aimed at achieving printed electronics started a decade later. This thesis treats printable organic electrochemical transistors (OECT). Some conjugated polymers can be switched between a high conducting and a low conducting state in an electrochemical cell.

  5. 13. New methods and reagents for small scale synthesis of phosphor organic compounds with focus on the phosphonic acids and their analogues

    Author : Rikard Wärme; Dan Johnels; Jacek Stawinski; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; micro scale; phosphorus oxyacids; solid phase; chlorination; fluorination; radiolabelling; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Abstract : The development of a synthetic method of radiolabelled methylphosphono-fluoridates on a milligram scale is presented. The aim of this method is, besides affording high yield, to choose reaction pathways and reagents so that handling and transfer of labelled toxic substances is minimised, thereby reducing the risk of exposure as much as possible.

  6. 14. Host-Guest Interactions for Structural Analysis of Organic Molecules : Development of new Tools for Stereochemical Characterization

    Author : Sandra Olsson; Adolf Gogoll; Kari Rissanen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metalloporphyrins; host-guest systems; bis-porphyrin tweezers; stiff stilbene macrocycles; organic synthesis; porphyrin binding studies; NMR; ECCD; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : The focus of this thesis is on the development of molecular tweezers as host-guest systems for stereochemical characterization of small organic molecules.There are two central problems to stereochemical characterization of small molecules. READ MORE

  7. 15. Electrochemical reduction of protons and organic molecules in hydrogen technologies : Liquid Organic Hydrogen carrier and Hydrogen Evolution

    Author : Hamid Ghorbani Shiraz; Magnus Berggren; Xavier Crispin; Ola Wendt; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogen Storage; LOHC; Hydrogen Evolution; Electrocatalyst;

    Abstract : In accordance with preventable actions to mitigate the effect of climate change in the modern societal applications, renewable energy is an unavoidable and decisive factor in the energy industry. The energy sources that offer non-depleted and environment-friendly pathways for the energy sector are in focus. READ MORE
