  2. 11. Design, Synthesis and Properties of Bipyridine-capped Oligothiophenes for Directed Energy and Electron Transfer in Molecular Electronic Applications

    Author : Lasse Nurkkala; Simon Dunne; Sarah Angus-Dunne; Edwin Constable; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular Electronics; Organic Synthesis; Ruthenium; Pyridyl Complexes; Ligand Design; Chemical engineering; Kemiteknik; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Abstract : The earliest landmark in computer technology was construction of the Electronic Numerial Integrator and Computer, ENIAC. Computational switching was performed with vacuum tubes and relays, rather large in size, making this computer rather unwieldy. READ MORE

  4. 12. Light interactions in flexible conjugated dyes

    Author : Jonas Sjöqvist; Patrick Norman; Per-Olof Åstrand; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; force field; molecular dynamics; QM MM; solvation effects; absorption spectroscopy; fluorescence spectrosocopy; infrared spectroscopy; Raman spectroscopy; stokes shift; conjugated polyelectrolytes;

    Abstract : In this thesis methodological developments have been made for the description of flexible conjugated dyes in room temperature spectrum calculations.The methods in question target increased accuracy and efficiency by combining classical molecular dynamics (MD) simulations with time-dependent response theory spectrum calculations.

  5. 13. Microenvironmental control and molecular detection of neural stem cell state and fate

    Author : Shirin Ilkhanizadeh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Neural stem cell growth and specialization is dependent on microenvironmental cues, such as growth factors, oxygen levels and substrate stiffness. Together these cues define the genetic and epigenetic program of neural stem cells. In our studies we have manipulated these cues in order to achieve better control of neural stem cell state and fate. READ MORE

  6. 14. PKB/Akt kinase localization and role in stemness maintenance in cancer

    Author : Mayur Vilas Jain; Karin Roberg; Piotr Religa; Mehrdad Rafat; Mahvash Tavassoli; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Cancer incidence rates have increased over the last decade. Currently available therapies are only moderately effective in targeting cancer cells. Established cancer treatment protocols fail to eliminate populations of cancer stem cells (CSCs), which develop resistance against the chemotherapeutic drugs and lead to cancer recurrence. READ MORE

  7. 15. Multimodal Porphyrin-Based Conjugates : Synthesis and characterization for applications as amyloid ligands, photodynamic therapy agents and chiroptical materials

    Author : Katriann Arja; Peter Nilsson; Peter Konradsson; Fredrik Almqvist; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Organic compounds that interact both with certain biological targets and display specific photophysical properties can be utilized as molecular tools to visualize and possibly effect disease related processes taking place in living organisms. In this regard, porphyrins are a class of naturally occurring molecules that possess intriguingly interesting photophysical properties where they can act as luminescent probes by emitting detectable light, as well as photosensitizers in the light mediated therapy called photodynamic therapy.
