  1. 1. POLYMER EXTRACTION AND UTILIZATION OF BROWN ALGAL BIOMASS

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Martin Sterner; KTH.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Algae; Saccharina latissima; alginate; brown seaweed; extraction; filament; chelation; gel; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Aquaculture is a field with a world changing potential. The areas at sea are enormous and aquatic cultivations impact both the environment and local ecology far less than land based cultivations. In the realm of algae, abundancies exists of nutrition, water and accessible sunlight, but there is constant shortage of places to dwell. READ MORE

  2. 2. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Diana Bernin; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gel; 1H NMR; diffusion; biomaterial; mass transport; pulsed field gradient NMR; 19F NMR; cellulose; dendrimer; alginate;

    Abstract : Soft biomaterials, such as gels, play an important role in different kinds of products and applications, in particular in drug delivery systems, health care products, and food. Polymer gel's great ability to control mass transport is applied on e.g. the uptake of liquids in diapers. READ MORE

  3. 3. Evaluation of Capillary Flow in Gels - The Liquid Uptake of Capillaries and Gelation Mechanisms in Alginate Gels

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Johanna Andersson; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; alginate gel; capillary action; Capillary flow;

    Abstract : For centuries it has been known that wetting liquids penetrate porous materials if the pores are sufficiently small. In some cases the liquid penetration is desired, like in kitchen paper or diapers, in other systems the penetration should be minimised or avoided, like in water repellent textiles or paper printing.

  4. 4. Surface tension-driven flow in soft porous materials — An investigation of the mechanism of capillary flow in microchannels of hydrogels

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Johanna Andersson; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capillary action; wetting on soft materials; Capillary flow; alginate gel;

    Abstract : Spontaneous spreading of liquids in porous materials is of great industrial relevance and occurs in, for example, diapers, fabrics, paper or paint. Often, it is necessary to manipulate the spreading rate of liquids to result in the desired mass transport, for example to soak up large liquid volumes, as in a diaper. READ MORE

  5. 5. Controlled release gel formulations and preclinical screening of drug candidates

    University dissertation from Umeå : Department of Chemistry

    Author : Tofeeq Ur-Rehman; Umeå universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; poloxamer; drug delivery; micellization; DMSO; calorimetry; NMR. in situ gelation; chitosan; preclinical pharmacokinetics; type III secretion inhibitors; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; Pharmaceutics; galenisk farmaci;

    Abstract : Simple gel formulations may be applied to enhance the systemic and local exposure of potential compounds. The aim of this thesis is the development and characterization of controlled release formulations based on thermo-reversible poloxamer gels, which are suitable for novel drug delivery applications.
