  2. 16. Biological and Biophysical Studies on Ruthenium Complexes

    Author : Anna Mårtensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metal susceptibility; DNA; antimicrobial; circular dichroism; ruthenium complex; linear dichroism; isothermal titration calorimetry; intercalation;

    Abstract : Small molecules that interact with DNA through intercalation are attractive candidates for treatments against cancer and microbial infections. Octahedral ruthenium(II) polypyridyl complexes, being substitution-inert, readily synthesized and coordinately saturated, has the potential of being developed in to a new family of drugs. READ MORE

  4. 17. Phase Behavior and Solution Properties of Aqueous Polyion-Surfactant Ion Systems

    Author : John Janiak; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer-surfactant association; complex salt; nonionic surfactant; poly acrylic acid ; poly methacrylic acid ; copolymer; polymeric counterion; decyl betainate; phase behavior; solubilization; mixed micelle; hydrolysis; release; liquid crystal; nanoparticles; thermosresponsive; C12E8; C12E5;

    Abstract : Polyelectrolytes and oppositely charged surfactants interact through attractive electrostatic forces, which in many cases lead to phase separation already at low total concentrations. During the past 10-15 years investigations of these systems have been simplified through the use of complex salts that consist of surfactants with polymeric counterions in a 1:1 charge stoichiometry (no excess simple counterions present).

  5. 18. Modeling adsorption of organic compounds on activated carbon : a multivariate approach

    Author : Jufang Wu; Anders Cedergren; Ingrid Fängmark; Ola Claesson; Lars-Gunnar Hammarström; Fritz Stoeckli; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; activated carbon; adsorption; adsorption capacity; adsorption rate; PCA; PLS; binary mixtures; Dubinin-Radushkevich; Wheeler-Jonas; Analytisk kemi; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Abstract : Activated carbon is an adsorbent that is commonly used for removing organic contaminants from air due to its abundant pores and large internal surface area. This thesis is concerned with the static adsorption capacity and adsorption kinetics for single and binary organic compounds on different types of activated carbon. READ MORE

  6. 19. Complexation between hydrophobically modified polymers and amylose. Gelation and competition by surfactants

    Author : Monica Egermayer; Kemiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; rheology; Physical chemistry; Fysikalisk kemi; inclusion complex; amylose; surfactant; ethyl hydroxyethyl cellulose; hydrophobically modified polymer; hydroxyethyl cellulose;

    Abstract : Aqueous mixtures of hydrophobically modified polymers (HMP) with amylose have been investigated by rheology and 1H NMR. Amylose can cross-link HMP chains by forming single-helical inclusion complexes with the hydrophobic side chains of the HMP, leading to thermoreversible, elastic, and thixotropic gels at ambient temperatures.

  7. 20. Effects of pharmaceuticals on natural microbial communities: Tolerance development, mixture toxicity and synergistic interactions

    Author : Sara Brosché; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; antibiotics; pharmaceutical mixtures; microbial community ecotoxicology;

    Abstract : Due to our extensive use of pharmaceuticals, low concentrations (picomol-nanomol/L) end up in the aquatic environment. Antibiotics comprise a group of pharmaceuticals specifically designed to disrupt microbial biochemical processes, and might therefore in particular have detrimental effects on microbial communities in the environment.
