  1. 1. Electrochemical behavior of conducting polymers

    Master-uppsats, KTH/Kemi

    Författare :Raghda Kalifa; [2022]
    Nyckelord :Cathodic protection; conducting polymers; conductivity; structure; compression; Katodiskt skydd; ledande polymerer; konduktivitet; struktur; kompression;

    Sammanfattning : Ett stort industriellt problem när det gäller metalliska material är korrosion. En metod för att förhindra korrosion är genom en elektrokemisk process som kallas katodiskt skydd vilket kan utföras på två olika sätt: Katodiskt korrosionsskydd med påtryckt ström (ICCP) eller offeranod (SACP).

  3. 2. Metal ion adsorption of highly mesoporous magnesium carbonate

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Rebecka Löfgren; [2019]
    Nyckelord :nanomaterial; water treatment; adsorption; metal removal; ion exchange; porous materials;

    Sammanfattning : In this project the adsorption ability of mesoporous magnesium carbonate (MMC) for copper (Cu), cobalt (Co), chromium (Cr) and arsenic (As) was evaluated. This was done by mixing MMC and dissolved metal (of different concentrations) and measuring the concentration of the solution before and after addition of MMC with Inductively coupled plasma optical emission spectroscopy.

  4. 3. Understanding Sn-seeded InSb nanowire growth

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Författare :Hengfang Zhang; [2017]
    Nyckelord :Science General;

    Sammanfattning : III-Sb semiconductor nanowires have drawn a lot of attention because of their many promising applications, such as thermoelectric generation, low power high efficient electronics and quantum transport. Gold as a catalyst seed particle has been dominating for many years assisting nanowires growth. LÄS MER

  5. 4. Evaluation of graphene as a transparent electrode in GaN-based LEDs by PECVD synthesis of graphene directly on GaN

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Linus Johansson; [2016]
    Nyckelord :PECVD; graphene; transparent electrode; gallium nitride; LED;

    Sammanfattning : A transparent conductive electrode (TCE) is an important component in many of our modern optoelectronic devices like photovoltaics, light emitting diodes and touch screens. These devices require good current injection and spreading as well as a high transparency. LÄS MER

  7. 5. Thermal Stability of Amorphous MoSiZr Thin Films

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Materialfysik

    Författare :Maciej Kaplan; [2016]
    Nyckelord :amorphous metals; metallic glasses; thermal stability; thin films; crystallisation temperature;

    Sammanfattning : Metallic glass is a class of materials which have a disordered structure of atoms, due to this, glasses lack grains and grain boundaries, which are present in their crystalline counterparts. Metallic glasses have many interesting properties worth investigating, such as high corrosion resistance or high mechanical strength. LÄS MER
