    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Johanna Swanelius; [2022]
    Nyckelord :Microfibrillated cellulose; MFC; waxy maize starch; rheology; temperature; viscosity; complex viscosity; stready shear viscosity curve; amplitude sweep; dry content; dynamic rotational rheometer; Mikrofibrillerad cellulosa; MFC; vaxartad majsstärkelse; reologi; temperatur; viskositet; komplex viskositet; flödeskurva; amplitudsvep; torrhalt; dynamisk reometer;

    Sammanfattning : Today, the focus lies on the state of the environment and how we can choose more sustainable alternatives to oil based materials. One material of interest is microfibrillated cellulose (MFC). LÄS MER

  3. 2. Improving the temporal resolution of a microspectrometer for the study of the photophysics of enhanced green fluorescent protein

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Lukas Rane; [2021]
    Nyckelord :Biophysics; EGFP; Fluorescence; triplet state; Biofysik; EGFP; fluorescens; triplet tillstånd;

    Sammanfattning : The use of fluorescent proteins as fluorescent markers has exploded over the last decades. In particular due to the development of advanced microscopy for live cell measurements, dynamic molecular studies down to single molecule levels and for superresolution microscopy. LÄS MER

  4. 3. Method development for rheological characterization of microfibrillated cellulose

    Master-uppsats, Karlstads universitet

    Författare :Elin Wahlkrantz; [2020]
    Nyckelord :microfibrillated cellulose; MFC; rheology; characterization; dynamic rotational rheometer; complex viscosity; amplitude sweep; dry content; pH; conductivity; measuring geometry; gel; mikrofibrillerad cellulosa; MFC; reologi; karakterisering; dynamisk rotationsreometer; komplex viskositet; amplitudsvep; torrhalt; pH; konduktivitet; mätgeometri; gel;

    Sammanfattning : This thesis contributes to a development of a method for rheological characterization of microfibrillated cellulose. The intended use of the method is to be able to distinguish between different grades of microfibrillated cellulose. LÄS MER

  5. 4. A Water Resistant Film Forming Emulsion - The First Steps towards a Topical Preventive Product against Intertriginous Dermatitis

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Ida Moen Larsson; [2017]
    Nyckelord :pharmaceutical technology; läkemedelsteknologi; Technology and Engineering; Biology and Life Sciences; Chemistry;

    Sammanfattning : Intertriginous dermatitis (Intertrigo) is a skin disease caused by friction between adjacent skin surfaces. Heat and moisture induces an inflammation, causing pain and often secondary infections. The aim of this degree project was to develop a prototype for a topical film forming emulsion for patients suffering from Intertrigo. LÄS MER
