2. 1. Novel oil resistant cellulosic materials

   Author : Christian Aulin; Lars Wågberg; Derek Gray; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oleophobic; MFC; cellulose; oil resistant; contact angle; XPS; SEM; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : The aim of this study has been to prepare and characterise oil resistant cellulosic materials, ranging from model surfaces to papers and aerogels. The cellulosic materials were made oil resistant by chemical and topographic modifications, based on surface energy, surface roughness and barrier approaches. READ MORE

4. 2. Molecular Exchange in Colloidal Dispersions

   Author : Alex Evilevitch; Kemiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; charged micoremulsion droplets; kinetics; mechanism.; Physical chemistry; Fysikalisk kemi; molecular transport; cell model; infinite dilution limit; turbidity measurements; oil solubilization; computer simulation; modeling; monomer diffusion; molecular exchange; Microemulsion droplets; oil droplets;

   Abstract : This thesis is a study of molecular exchange between the aggregates in a colloidal dispersion. The problem of oil molecular transport at resolubilization of big oil drops by smaller microemulsion droplets is considered as an experimental model system. READ MORE

5. 3. Emulsification of Alkyl Ketene Dimer (AKD) -characterization of dispersions and emulsifiers

   Author : Kristina Mohlin; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrolysis; droplet size; hydrophobizing agent; dispersion; surfactant; AKD; emulsification; viscosity; surface tension; polymer; phase behavior; Alkyl Ketene Dimer;

   Abstract : Alkyl Ketene Dimer (AKD) is a commonly used hydrophobizing agent in the paper industry, introducing capillary absorption barriers for polar liquids, which makes the paper more resistant to liquid penetration. Since AKD is a so-called internal sizing agent it is usually added in the form of a water-borne dispersion. READ MORE

6. 4. Dispersion Coating for Active Food Packaging: Aroma Interactions and Oxygen Scavenging

   Author : Anna Nestorson; Lars Järnström; Anders Leufvén; Caisa Andersson; José M. Lagaron; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active food packaging; Dispersion coating; Latex; Aroma compounds; Oxygen scavenging; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

   Abstract : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. READ MORE

7. 5. Submicron gas bubbles in water

   Author : Fredrik Eklund; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microbubbles; nanobubbles; ultrafine bubbles; digital holographic microscopy; nanoparticle tracking analysis;

   Abstract : Gas bubbles smaller than 1 micrometre in water, commonly referred to as nanobubbles, is a growing field of research and innovation. Applications range from medical imaging and drug delivery to mining industry and environmental remediation. READ MORE
