  1. 1. Physico-Chemical Investigations of Bilayer Discs and Related Lipid Structures Formed in Liposomal Systems Intended for Triggered Release

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Sandström; Uppsala universitet.; [2007]
    Nyckelord :Physical chemistry; liposome; triggered release; pH-sensitive liposomes; temperature-sensitive liposomes; drug partitioning; cryo-TEM; discs; Fysikalisk kemi;

    Sammanfattning : This thesis describes results from fundamental studies of liposomes intended for drug delivery and pH or temperature triggered release. In addition, the effect of lipid composition on bilayer disc formation and a potential application of the bilayer discs were investigated. LÄS MER

    Sammanfattning : The number of diabetics, obese individuals and other patients carrying other lifestyle diseases is increasing worldwide. At the same time the population is ageing. These patients all suffer from poor blood circulation, which often gives rise to non-healing, or chronic, wounds. Thus, the number of chronic wounds is also increasing at a fast pace. LÄS MER

    Sammanfattning : Advancements in drug delivery have enabled a wider array of prevention, control and treatment of diseases such as cancer. Drug delivery systems have the possibility of encapsulating drugs with low solubility, delivering them to specific locations in the body as well as obtaining a controlled and sustained drug release.

    Sammanfattning : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER

  5. 5. Atmospheric corrosion of zinc-aluminum and copper-based alloys in chloride-rich environments Microstructure, corrosion initiation, patina evolution and metal release

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Xian Zhang; KTH.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atmospheric corrosion; chloride deposition; Zn-Al alloy coatings on steel microstructure; Cu sheet and Cu alloys; microstructure; corrosion initiation; corrosion product evolution; metal release; SEM; IRAS; CRM.; Kemi; Chemistry;

    Sammanfattning : Fundamental understanding of atmospheric corrosion mechanisms requires an in-depth understanding on the dynamic interaction between corrosive constituents and metal/alloy surfaces. This doctoral study comprises field and laboratory investigations that assess atmospheric corrosion and metal release processes for two different groups of alloys exposed in chloride-rich environments.
