  2. 1. Physico-chemical characterisation of novel surfactants

    Author : Britta M. Folmer; KTH; []
    Keywords : Natural raw materials; novel hydrophobes; physico-chemical characterisation; micelles; interfacial adsorption; liquid crystals; enzymes; polymers; complex formation; foam;

    Abstract : The aim of this thesis has been to investigate thephysico-chemical behaviour of novel surfactants based onnatural raw materials. Micellization properties, adsorptionatinterfaces and dynamic aspects have been studied. In additioncomplex formation of surfactants with enzymes and polymers hasbeen evaluated. READ MORE

  4. 2. Physico-chemical characteristics and quantitative structure-activity relationships of PCBs

    Author : Patrik Andersson; Stephen Safe; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polychlorinated biphenyls; PCBs; physico-chemical properties; statistical design; multivariate; PCA; PLS; biomagnification; BMF; bioassay; CYP1A; SAR; QSAR; REPs; risk assessment; Chemistry; Kemi; Chemistry; Kemi;

    Abstract : The polychlorinated biphenyls (PCBs) comprise a group of 209 congeners varying in the number of chlorine atoms and substitution patterns. These compounds tend to be biomagnified in foodwebs and have been shown to induce an array of effects in exposed organisms. READ MORE

  5. 3. Liposomes for Drug Delivery : from Physico-chemical Studies to Applications

    Author : Nill Bergstrand; Katarina Edwards; Felix M Goni; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liposome; steric stabilisation; BNCT; cryo-TEM; EGF; targeting; stability; permeability; pH-sensitive liposomes; triggered release; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : Physico-chemical characterisation of structure and stability of liposomes intended for drug delivery is the central issue in this thesis. In addition, targeted liposomes to be used in boron neutron capture therapy (BNCT) were developed.Lysolipids and fatty acids are products formed upon hydrolysis of PC-lipids. READ MORE
