  1. 1. Synthesis and Characterization of Sec-Packings Based on Trimethylolpropane Trimethacrylate

    Author : Andrea Schmid; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bulk polymerization; N; hydrophilic gels; separation; methyl methacrylate; hydrophobic networks; acrylamide; porous networks; Suspension; N -methylene-bis-acrylamide; chemically crosslinked networks; dry gels; polysaccharide standards; distilled water; copolymerization; trimethylolpropane trimethacrylate;

    Abstract : Suspension and bulk polymerization of trimethylolpropane trimethacrylate (TRIM) and copolymerization of TRIM with methyl methacrylate (MMA) resulted in porous, hydrophobic, and chemically crosslinked networks. Copolymerization of TRIM with acrylamide (AA) and with N,N'-methylene-bis-acrylamide (bis-AA) resulted in hydrophilic gels. READ MORE

  2. 2. Exploring the functionality of coconut proteins

    Author : Borges Chambale; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coconut; coconut milk; extraction; proteins; emulsions; functional properties; denaturation; gels; yield stress; glass structure;

    Abstract : At present, coconut proteins are discarded as a waste product by the coconut oil industry. If the range of applications of coconut proteins is to be expanded, their potential functionalities should be investigated. Emulsions and gels are of the greatest interest in food industry.

  3. 3. Thin water and ice films on minerals : a molecular level study

    Author : Merve Yeşilbaş; Jean-François Boily; Johannes Messinger; Grégory Lefèvre; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; ice; cryosalt; minerals; rocks; atmosphere; Dynamic Vapour Sorption; FTIR; cryo-FESEM; fysikalisk kemi; Physical Chemistry;

    Abstract : Minerals in Earth’s crust and suspended in the atmosphere form water or ice films as thin as a few nanometers to as thick as a few micrometers, and beyond. Mineral-bound water and ice films in terrestrial systems (e.g. READ MORE

  4. 4. Modulating the structure-function relationship of mucin materials

    Author : Kun Jiang; Thomas Crouzier; Qi Zhou; Mark Tibbitt; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioteknologi; Biotechnology;

    Abstract : Mucus covers the epithelium surfaces playing a key role in the barrier, hydration, lubrication and bioactivity functions for the human body, and mucins are the fundamental components of mucus which provide such functions. However, many details in how these functions are related to the many structural features of mucins are still unknown. READ MORE

  5. 5. Model studies of cellulose fibers and films and their relation to paper strength

    Author : Susanna Fält; KTH; []
    Keywords : absorption; carboxymethyl cellulose; cellulose fibers; dissolving pulps;

    Abstract : The objectives of this work were (i) to develop a new methodfor the preparation of thin cellulose model films, (ii) to usethese model films for swelling measurements and (iii) to relatethe swelling of fibers and films to the dry strength ofpaper.In the new film preparation method, NMMO(N-methylmorpholine-N-oxide) was used to dissolve cellulose andDMSO (dimethyl sulfoxide) was added to control the viscosity ofthe cellulose solution.
