  1. 1. Water-in-diesel emulsion and microemulsion fuels: composition, structure and effect on emissions

    Author : Anna Lif; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NOx; microemulsion; combustion; diffusometry; alternative fuels; emission; emulsion; Fischer-Tropsch; MFC; PM; microfibrillated cellulose; NMR; surfactant; soot; diesel;

    Abstract : Water-in-diesel fuels, as emulsions and microemulsions, give reduced emissions of nitrogen oxides (NOx) and particulate matter (PM) in combustion in diesel engines compared to regular diesel. These fuels can contribute to an improved local environment in densely populated areas as they can replace regular diesel in existing vehicles without any engine modification requirements. READ MORE

  2. 2. Film Formation from Dispersions - Preparation and Mechanisms

    University dissertation from Department of Polymer Science & Engineering, Lund University

    Author : Stefan Erkselius; Lunds universitet.; Lund University.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Polymer technology; decomposition; sodium persulfate; hyrdoxyethyl cellulose; salt; surfactants; drying; stabilization; latex; Film formation; dispersions;

    Abstract : Improved environmental consciousness and harsh legislation concerning volatile organic compounds (VOCs) during the 1980s led to an increase in the development in the field of polymer colloids. Solvent born coatings were replaced by polymer dispersions in aqueous solution, so called latex dispersions. READ MORE

  3. 3. Starch Pickering Emulsions : Process and Encapsulation Stability

    University dissertation from Department of Food Technology, Lund University

    Author : Ali Marefati; Lunds universitet.; Lund University.; [2018-02-27]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch granules; Pickering emulsions; Encapsulation; Freeze-thaw stability; Freeze-drying; In vitro digestion; In vitro intestinal lipolysis;

    Abstract : The emulsion stabilization functionality of surfactants and biopolymers can be replaced by solid particles adsorbed at the interface, where they create a category of emulsions known as Pickering emulsions. Recently, health and environmental concerns have led to new market demand for natural, biodegradable and renewable sources of ingredients. READ MORE

  4. 4. Fabrication of Functional Molecularly Imprinted Materials using Nanoparticle Building Blocks

    University dissertation from Department of Food Technology, Lund University

    Author : Changgang Xu; Lunds universitet.; Lund University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecularly imprinted polymers; magnetic susceptibility; click chemistry; PFPA; Pickering emulsion; chemical conjugation;

    Abstract : Popular Abstract in Undetermined Nanoparticles have attracted great interest in biomedicine and material science due to their unique and unconventional properties. Polymer nanoparticles containing pre-designed molecular recognition sites can be synthesized using molecular imprinting technique. READ MORE

  5. 5. Formulation and characterization of W/O nano-dispersions for bioactive delivery applications

    University dissertation from Örebro : Örebro university

    Author : Maria D. Chatzidaki; Örebro universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nano-dispersions; encapsulation; food; DLS; EPR; Cryo-TEM; SAXS; pH-stat; digestion; antioxidants; gastric lipase; pancreatic lipase; Kemi; Chemistry;

    Abstract : The main objective of this study was the formulation of food-grade water-in-oil (W/O) nano-dispersions based mainly on medium or long-chain triglycerides. Two types of dispersions were formulated and structurally compared, namely emulsions and microemulsions. READ MORE
