  1. 1. Salting-out of Colloidal Latex Particles Grafted with Poly(ethylene glycol)

    Författare :Kristin Jonsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEG; fluorinated colloids; monodisperse spheres; steric stability; emulsion polymerization; SAXS; crosslinking; salting-out; interfacial tension; SANS;

    Sammanfattning : Colloidal particles dispersed in a medium are important both in nature and in industry. The stability of colloidal particles is determined by the interactions between them and can be improved by steric stabilization. There is no conclusive understanding of how these sterically stabilized particles become unstable. LÄS MER

  3. 2. Alkylglycoside Surfactants - Self-Assembly, Solid-State Properties and Interactions with Hydrophobic Molecules

    Författare :Caroline Ericsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; peptide stabilisation; solubilisation; micelle morphology; solid-state behaviour; alkylglycosides; nonionic surfactants;

    Sammanfattning : A thorough physical-chemical characterisation of alkylglycosides has been performed. The effects of temperature, salt, concentration and deuterium exchange on the self-aggregation of n-nonyl-b-D-glucoside (b-C9G1) and n-tetradecyl-b-D-maltoside (b-C14G2) have been studied in dilute solutions by static and dynamic light scattering, neutron scattering, rheology, capillary viscometry and tensiometry.

  4. 3. Process based Modelling of Chemical and Physical Aerosol Properties Relevant for Climate and Health

    Författare :Pontus Roldin; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gas phase chemistry; aerosol dynamics; aerosol particles; climate; kinetic multilayer model; Fysicumarkivet A:2013:Roldin;

    Sammanfattning : Atmospheric aerosol particles have substantial influence on climate and air quality. However, the anthropogenic influence on the atmospheric aerosol is still poorly known. This limits the understanding of past and future climate changes. LÄS MER

  5. 4. Protein stability and mobility in live cells : Revelation of the intracellular diffusive interaction organization mechanisms

    Författare :Xin Mu; Mikael Oliveberg; Johan Elf; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusive interactions; macromolecular crowding; protein thermodynamic stability; protein mobility; in-cell NMR; Hofmeister series; Biochemistry; biokemi;

    Sammanfattning : Biochemical processes inside living cells take place in a confined and highly crowded environment. As such, macromolecular crowding, one of the most important physicochemical properties of cytoplasm, is an essential element of cell physiology. LÄS MER

  7. 5. Aroma Partition and Release from Soft Drinks, Jam, and Jellied Sweets

    Författare :Annika Hansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas chromatography; aroma; gel; model mouth; partition coefficient; release; citric acid; pectin; in-nose; sugar; proton-transfer reaction mass spectrometry; soft drink;

    Sammanfattning : The research described in the present thesis was focused on the influence of food ingredients and structures on the partition and release of aroma compounds from model systems such as soft drinks, jam, and jellied sweets. The effects on aroma release were studied during both static and dynamic conditions, the latter by both model mouth and in-nose measurements. LÄS MER
