  1. 11. Cation Solvation in Water and Acetonitrile from Theoretical Calculations

    Författare :Daniel Spångberg; Kersti Hermansson; Philippe Bopp; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; molecular dynamics; ab initio; lithium; sodium; magnesium; aluminum; metal ion; water; acetonitrile; solution; solvation; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Metal ions solvated in aqueous, non-aqueous, and mixtures of solvents occur in many chemical contexts, for example in electrochemical applications and solvent separation. Solvated ions appear in high concentration in the living organisms, where their presence or absence can fundamentally alter the functions of life. LÄS MER

  3. 12. A Solution Exchange Platform for Exposure of Cells to Chemical Waves

    Författare :Jessica Olofsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; waveform synthesis; solution exchange; cell signalling; patch clamp; receptor; high through-put; microfluidics; microfabrication; channel; chemical oscillations; ion channel; poly dimethylsiloxane ; drug discovery;

    Sammanfattning : This thesis presents the development, characterization and suggested applications of a platform for controlling the chemical environment around a cell or a cell constituent. The platform is unique in its capability to combine rapid solution switching with precise timing and access to a manifold of solution environments. LÄS MER

  4. 13. Studies of ligand- and temperature-gated ion channels using microfluidic methods

    Författare :Maria Millingen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; solution exchange; desensitization; temperature-gated; ion channel; temperature control; ligand-gated; TRPV1; GABAA receptor; microfluidics;

    Sammanfattning : This thesis describes the studies of the GABAA receptor, a ligand-gated ion channel, and the ligand- and temperature-gated ion channel TRPV1. The desensitization behavior of both of these proteins has been studied for different conditions, using a microfluidic device for superfusion. LÄS MER

  7. 15. Femtosecond Dynamics and Photochemistry in Solution

    Författare :Marcus Rasmusson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; cross-correlation function; chloroiodomethane; dihalides; bromobenzene; ion pairs; solvation; vibrational relaxation; charge-transfer; tetranitromethane; electron transfer; femtosecond spectroscopy; dissociation; Photochemistry; Fotokemi; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : The reaction dynamics of several polyatomic systems have been investigated in solution by femtosecond spectroscopy. Tetranitromethane-naphtalene complexes excited in the charge-transfer band at 400 nm undergo dissociative electron transfer, resulting in three primary products: [naphthalene].+, NO2 and C(NO2)3-.
