  1. 1. Lithium intercalation in tin oxide films : Physics and electrochemistry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jan Isidorsson; Uppsala universitet.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : Tin oxide films were made by reactive rf magnetron sputtering under conditions that led to both electronic and ionic conductivity. It was found that a high sputter pressure promoted porosity and a high charge capacity. READ MORE

  2. 2. Electrochemistry of Heme Containing Enzymes - Fundamentals and Applications

    University dissertation from Analytical Chemistry, Lund University

    Author : Annika Lindgren; Lund University.; Lunds universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phenol monitoring; spectroelectrochemistry; self-assembled monolayer; gold electrode; graphite electrode; direct electron transfer; cellobiose dehydrogenase; biosensor; peroxidase; kinetics; Electrochemistry; Elektrokemi;

    Abstract : The thesis is a bioelectrochemical study of heme enzymes, mainly peroxidases and cellobiose dehydrogenases (CDH). It covers both fundamental and applied aspects, viz. studies of the direct electron transfer and kinetics of enzymes on electrodes, and the development of amperometric enzyme-based biosensors.

  3. 3. Fundamental Insights into the Electrochemistry of Tin Oxide in Lithium-Ion Batteries

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Solveig Böhme; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tin; Tin oxide; Lithium-ion batteries; Electrochemistry; High temperature cycling; Conversion reaction; XPS; SEM; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : This thesis aims to provide insight into the fundamental electrochemical processes taking place when cycling SnO2 in lithium-ion batteries (LIBs). Special attention was paid to the partial reversibility of the tin oxide conversion reaction and how to enhance its reversibility. READ MORE

  4. 4. PROBING SECRETORY VESICLES AND LIPOSOME MODEL SYSTEMS USING NANOSCALE ELECTROCHEMISTRY AND MASS SPECTROMETRY

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jelena Lovric; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neuroendocrine cells; NanoSIMS; liposomes; neurotransmitters; large dense core vesicles; Exocytosis; ToF-SIMS; vesicle electrochemical cytometry; electrochemistry; amperometry;

    Abstract : Cellular communication is based on the process of exocytosis, regulated release of chemical messengers into the extracellular space. These messengers, neurotransmitters, are packed into vesicles that during exocytosis fuse with the plasma membrane and release their content. READ MORE

  5. 5. Bipolar electrochemistry for high throughput screening applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sara Munktell; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bipolar electrochemistry; electrodeposition; corrosion; screening; gradients; recycling; gold nanoparticles; Scanning Droplet Cell; Hard x-ray photoelectron spectroscopy; pitting corrosion; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Bipolar electrochemistry is an interesting concept for high throughput screening techniques due to the ability to induce gradients in a range of materials and their properties, such as composition, particle size, or dopant levels, among many others. One of the key advantages of the method is the ability to test, create or modify materials without the need for a direct electrical connection. READ MORE
