  1. 1. Coacervates as a subcutaneous drug delivery system

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för läkemedelskemi

    Författare :Dania Elkhalifa; [2022]
    Nyckelord :;

    Sammanfattning : Subcutaneous administration of biological drugs has become highly attractive as it offers the possibility for patient self-administration. Coacervates as a subcutaneous drug delivery system provide a way to decrease injection volumes thereby reducing the risk of injection site pain. LÄS MER

  3. 2. 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

  4. 3. Evaluation of joint formation on cellulosic surfaces

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Erika Fivaz; [2020]
    Nyckelord :;

    Sammanfattning : Environmental issues are more and more present in our societies. Pollution engendered by plastic waste have drastically increased these past decades, causing several threats to the ecosystem. Therefore, the need of new biodegradable plastics to replace the actual petroleum-based ones is urgent. LÄS MER

  5. 4. Characterization of the Electrical Resistivity and Water Sorption Properties of a Semiconducting Swelling Tape

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Maria Nicte Polanco Olsen; [2018]
    Nyckelord :;

    Sammanfattning : I närvaro av fukt och lokaliserade fältförbättringar kan vattenträd utvecklas inom polymerisoleringen av HV subsea kraftkablar. Vattenträd tenderar att växa obemärligt och försämra isolationsegenskaperna med tiden. Fuktigheten i isoleringen kan effektivt reduceras genom applicering av halvledande svällningsband. LÄS MER

  7. 5. Dyeing of Wool and Silk Fibres with a Conductive Polyelectrolyte and Comparing Their Conductance

    Magister-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :Muhammad Ahsen Khan; [2012]
    Nyckelord :conjugated polyelectrolyte; conductive polymers; conductive protein fibres; fluorescent dyes;

    Sammanfattning : Polyelectrolytes are conductive polymers because of their ionic side group and PEDOT-S is one of those conductive polyelectrolytes. Previously, recombinant silk fibre has been dyed with PEDOT-S. PEDOT-S showed that it can be dyed with recombinant silk fibre over a very wide range of pH from 11 to 1.7. LÄS MER
