  1. 1. Graphene Based Aqueous Ammonium Dual-Ion Batteries

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Arvid Sandberg; [2023]
    Nyckelord :Dual ion batteries; materials science; chemistry; organic polymer;

    Sammanfattning : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. LÄS MER

  3. 2. Additive Manufacturing of Strain Gauges : A Study of the Feasibility of Printing Strain Gauges Using Inkjet Printing

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Karin Wennersten; [2022]
    Nyckelord :Additive manufacturing; strain gauge; inkjet; IJP; AJP; aerosol jet;

    Sammanfattning : Additive manufacturing (AM) also commonly known as 3D-printing is a manufacturing method which creates parts from adding layer into another. In the field of printed electronics Inkjet printing (IJP) and Aerosol Jet printing (AJP) are the most common AM techniques. LÄS MER

  4. 3. Capillary Organic Electronic Ion Pump for Delivering Malic Acid - Towards Better Understanding of Drought Tolerance in Tropical Plants

    Master-uppsats, Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Författare :Alexandra Sandéhn; [2021]
    Nyckelord :malic acid; malate; ion delivery; implantable devices; organic bioelectronics; plants; Teknisk fysik; Teknisk fysik;

    Sammanfattning : Delivery of biologically relevant ions such as drugs, neurotransmitters and hormones have been recognized as powerful a tool to control physiology of animals and plants for research purposes and practical applications. In the plant research community, ions are most commonly delivered as part of a solvent by soaking, spraying, pipetting or by adding to the soil. LÄS MER

  5. 4. Viability of PEEK for high-temperaturemicrovascular composites manufacture

    Master-uppsats, Luleå tekniska universitet/Materialvetenskap

    Författare :Yago Domínguez Muñoz; [2021]
    Nyckelord :Materials; composite; microvascular; PEEK; high-temperature;

    Sammanfattning : Microvascular composites are materials with an inner hollow network which allows thecirculation of fluids. This functionalizes the composite materials, giving them furtherapplications such as self-healing or active cooling. LÄS MER

  7. 5. Polyimide thin-ply composite

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :KHALID MOUANE; [2018]
    Nyckelord :Polyimide; thin-ply; microcracking; curing stress; mechanical loading;

    Sammanfattning : Mechanical performance of composite structures is influenced by the accumulation of damage from the manufacturing process and throughout the whole service life. For instance, an aircraft is subjected to a combination of mechanical loading and the thermo-oxidative environment from the take-off to the landing. LÄS MER
