  2. 1. Dissolution of cellulose for textile fibre applications

    Author : Martin Kihlman; Ulf Germgård; Mats Westin; Lars Stigsson; Stefan Backa; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkaline aqueous solvent systems; cellulose; dissolution; dissolving pulp; kraft pulp; pretreatment; pulp characterization; sulfite pulp; textile fibres; Chemical Engineering; Kemiteknik;

    Abstract : This thesis forms part of a project with the objective of developing and implementing a novel, wood-based, process for the industrial production of cellulose textile fibres. This new process should not only be cost effective but also have far less environmental impact then current processes. READ MORE

  4. 2. Development of bixin formulations. Extraction, microencapsulation, dispersibility and photostability

    Author : Cecilia Curi; Avdelningen för livsmedel och läkemedel; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bixin; annatto; natural colorants; light stability in solid multiphase systems; shelf life extension; auqeous physical stability; encapsualtion efficiancy; spray drying; natural colored candies;

    Abstract : The aril that covers the seeds of the plant species Bixa orellana is composed of the natural colorants bixin and norbixin, phenolic components and native carbohydrates composed of hemicellulose, starch, and a small fraction of proteins. Bixin is a hydrophobic carotenoid that is water insoluble and is mostly used for coloring oil-based formulations. READ MORE

  5. 3. On the interactions of ions and odor molecules with nanomaterials in water and synthetic urine

    Author : Isabelle Simonsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanomaterials; Surface chemistry; Ion specific effects; MOF synthesis; Odor control; Adsorption; Synthetic urine;

    Abstract : Towards the quest of finding materials to be used as adsorbents in real systems, it is crucial to understand the underlying adsorption processesfully. In many applications, adsorption occurs in biological fluids containing a vast range of ions, organic molecules, and biomolecules. READ MORE
