  1. 1. Electrochemical investigations on lipid cubic phases

    Detta är en avhandling från Umeå : Umeå University

    Författare :Mohammad Yaser Khani Meynaq; Umeå universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monoolein; Electrochemical Impedance Spectroscopy; lipid cubic phase; ionic interaction; biofuel cell; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Electrochemical Impedance Spectroscopy (EIS) was used to develop a novel methodology for studying ionic interaction with lipids arranged in a lipid cubic phase (LCP). Studying different types of ions, both cations and anions, validated the method. LÄS MER

  2. 2. Smartware electrodes for ECG measurements Design, evaluation and signal processing

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Linda Rattfält; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of this thesis work has been to study textile and screen printed smartware electrodes for electrocardiographic (ECG) measurements both in terms of their electrode properties and possibility to further improve their robustness to movement induced noise by using signal processing. Smartware electrodes for ECG measurements have previously been used in various applications but basic electrical electrode properties have not sufficiently been looked into. LÄS MER

  3. 3. Electrochemical monitoring of living cells

    Detta är en avhandling från Analytical Chemistry, Lund University

    Författare :Christer Spegel; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PC12; redox; electrochemistry; NAD P H; Single cell; Microchip; S. cerevisiae;

    Sammanfattning : This thesis presents the utilization of electroanalytical methods for analysis of dynamic cellular processes such as exocytosis, intracellular redox reactions and cell surface interactions. Microchips have been designed and manufactured with the purpose of monitoring dopamine exocytosis from single or a small ensemble of PC12 cells. LÄS MER

  4. 4. Hydrophobic and superhydrophobic coatings for corrosion protection of steel

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Lina Ejenstam; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Superhydrophobic coating; hydrophobic coating; corrosion protection; contact angles; electrochemical measurements; surface characterization; Kemi; Chemistry;

    Sammanfattning : Since metals in general, and steels in particular, are vital construction materials in our modern society, the corrosion protection of said materials is of great importance, both to ensure safety and to reduce costs associated to corrosion. Previously, chromium (VI) and other harmful substances were effectively used to provide corrosion protection to steel, but since their use was heavily regulated around year 2000, no coating has yet been developed that, in a fully satisfactory manner, replaces their corrosion protective properties.

  5. 5. In-situ Studies of Spontaneous Potential Oscillations during Electrochemical Deposition of Copper and Cuprous Oxide

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sofia Leopold; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Spontaneous potential oscillations; electrochemical deposition; in-situ pH measurement; in-situ confocal Raman measurement; copper and cuprous oxide; Oorganisk kemi; NATURAL SCIENCES Chemistry Inorganic chemistry; NATURVETENSKAP Kemi Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Self-oscillating behaviour in alkaline Cu(II)-lactate and -tartrate systems has been investigated by in-situ pH and confocal Raman spectroscopy measurements. Formation of Cu(II)-lactate and -tartrate complexes is a key factor underlying the self-oscillations. LÄS MER
