  2. 1. Imidazole containing polymers complexed with Cu2+ and Zn2+

    Author : Markus Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; vibrational spectroscopy; far-FTIR; EPR; cross-linking; DSC; Coordinating polymer; imidazole; mid-FTIR; metal ion;

    Abstract : An enormous problem for the shipping industry is fouling of marine organisms such as algae andbarnacles on the boat hull. The negative consequences for the society are both economical as well asenvironmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. READ MORE

  4. 2. Modification of microcapsules for controlled release

    Author : Markus Andersson Trojer; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; block copolymer; coordination chemistry; polyelectrolyte multilayer; cross-linking; vibrational spectroscopy; electron paramagnetic resonance; imidazole; controlled release; colloidal stability; Microcapsule; quartz crystal microbalance with dissipation;

    Abstract : 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. READ MORE

  5. 3. Hydrogen Bonded Phenols as Models for Redox-Active Tyrosines in Enzymes

    Author : Josefin Utas; Björn Åkermark; Helena Grennberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron transfer; photosystem II; radicals; imidazole; hydrogen bonding; Organic chemistry; Organisk kemi;

    Abstract : This thesis deals with the impact of hydrogen bonding on the properties of phenols. The possibility for tyrosine to form hydrogen bonds to other amino acids has been found to be important for its function as an electron transfer mediator in a number of important redox enzymes.

  6. 4. Cross-linking and surface properties of EHEC and Starch -a QCM-D study

    Author : Jesper Hedin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrogel; GMA; HM-EHEC; Starch; vicoelastic properties; Imidazole; QCM-D; SPR; EHEC;

    Abstract : The increase of the green house gases and the crude oil price has resulted in a willingness to change the raw material in many industries from petroleum-based polymers to natural polymers. One such natural polymer is starch. Today, starch is used in the glue industry in wallpaper pastes. READ MORE

  7. 5. Aromatic Allylation via Diazotization; Application in synthesis of heterocyclic compounds

    Author : Fredrik Ek; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bengamide analogue.; parallel synthesis; trimethylsilyl azide; cycloaddition; imidazole; fused tetrazole derivatives; iodocyclization; benzazepine; tert-butyl nitrite; allylic bromide; aromatic allylation; diazotization; Organic chemistry; Organisk kemi;

    Abstract : A new method for allylation of aromatic systems has been developed. A number of arylamines were converted via diazotization to the corresponding allylaromatic compounds using tert-butyl nitrite and an excess of allylic bromides with complete regioselectivity. Electron-withdrawing groups, in the aromatic moiety, were necessary to obtain good yields. READ MORE
