  1. 6. Starch Pickering Emulsions : Process and Encapsulation Stability

    Författare :Ali Marefati; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :Starch granules; Pickering emulsions; Encapsulation; Freeze-thaw stability; Freeze-drying; In vitro digestion; In vitro intestinal lipolysis;

    Sammanfattning : 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. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; probiotics; L. reuteri; oxygen; fermentation; heterogeneity; morphology; flow cytometery; freeze-drying; stress tolerance; Online flow cytometry; k-means clustering; fatty acids; defined minimal media; pre-formulation hold time;

    Sammanfattning : Optimisation of cultivation conditions in the industrial production of probiotics is crucial to reach a high-quality product with high probiotic functionality. The production process includes a fermentation step to produce biomass, accompanied by centrifugation to concentrate the cells. LÄS MER

  5. 9. Silver Alumina Catalysts for Lean NOx Reduction - Influence of Preparation Methods and Type of Reductant, with Transient Kinetic Modelling

    Författare :Hannes Kannisto; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silver; kinetic modelling; Lean NOx reduction; sol-gel; preparation method; dispersion; cluster; HC-SCR; freeze-dry; XPS; alumina;

    Sammanfattning : The objective of this work was to compare three different preparation methods for silver alumina catalysts for lean NOx reduction. Characteristics such as catalytic activity with propene and n-octane as reductants, chemical state of the silver and silver dispersion were analyzed. LÄS MER

  7. 10. Multifunctional Foams Based on Nanomaterials from Plants and Textile Waste

    Författare :Carina Schiele; Lennart Bergström; Emily Cranston; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multifunctional foams; nanofibers; aramid; cotton; nanocellulose; heat transport; thermal conductivity; electromagnetic shielding; supercritical drying; freeze drying; materialkemi; Materials Chemistry;

    Sammanfattning : Nanoparticles extracted from plants or textile waste are promising candidates for the design of sustainable materials. In this thesis, I explored how nanoparticles extracted from trees and from Kevlar and cotton textile wastes can be processed to form lightweight composite foams. LÄS MER
