  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. Influence of level of cellulose oxidation and surface treatment on the adhesion between cellulose beads

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

    Författare :Rasmus Källgren; [2020]
    Nyckelord :Cellulose; Fibre; Surface Coating; Layer-by-Layer; Oxidation; Cellulosa; Fiber; Ytbehandling; Layer-by-Layer; Oxidation;

    Sammanfattning : With the growing impact of climate change on both political decisions and how companies develop their products, it is increasingly important to find environmentally friendly alternatives to fossil-based materials. One of the more interesting materials in this respect is cellulose, which is the world's most naturally occurring polymer and can be used in a variety of applications. LÄS MER

  4. 3. Towards stimuli-reformable paperboard and flipped classroom in chemistry education : A study of how to create a paper with controllable mechanical properties and a study in how the flipped classroom is used in chemistry education

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för teknikvetenskaplig kommunikation och lärande (ECE)

    Författare :David Pettersson; [2017]
    Nyckelord :Alginate; Cationic cellulose nanofibrils; Cross-linking; Dialcohol cellulose;

    Sammanfattning : Today, paper and paperboard is an important part of the packaging industry, as well as natural part of our daily lives. The alternatives to paper and paperboard is often produced from nonrenewable sources such as petroleum and as demands on sustainability increase in the packaging sector, it gives paper a desirable advantage over plastics.

  5. 4. 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

  7. 5. Modification of nanofibrillated cellulose with stimuli-responsive polymers

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Carmen Cobo Sanchez; [2012]
    Nyckelord :thermoresponsive; nanofibrillated cellulose; biocomposites; block-copolymer; stimuliresponsive;

    Sammanfattning : Research of new sustainable and low cost materials, such as cellulose, is of high interest. Modifications of the cellulose can be performed in order to create a “smart” material which responds to external stimuli, such as variations in pH and temperature, by changing its properties. LÄS MER
