  1. 16. Organic Reactions i Organised Media

    Författare :TOMASZ WITULA; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nucleophilic substitution; mesoporous material; microemulsion; silica; lipase; Liquid crystal; alumina; entrapment.; heterogenized; titania; organic synthesis;

    Sammanfattning : A common problem in synthetic organic chemistry is reactant incompatibility between lipophilic organic compounds and inorganic salts. The thesis reports an investigation of some organic reactions, involving incompatible substrate and nucleophile, performed in liquid crystalline phases and also in slurries of mesoporous materials with different symmetry.

  3. 17. Short-Chain Fatty Acid Starch Stabilized Pickering Emulsions : Design, Properties and Applications

    Författare :Nabilah Binti Abdul Hadi; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Short-chain fatty acid starch; Physicochemical properties; Pickering emulsions; Starch modification; Emulsion stability; Starch hydrolysis; In vitro digestion; Lipolysis;

    Sammanfattning : Pickering emulsions are emulsions stabilized by solid particles. Particles with optimal dual wettability toward both of the oil and water phases, can be adsorbed onto the interface, thereby providing the stability of the emulsions. LÄS MER

  4. 18. Multifunctional Dendritic Scaffolds: Synthesis, Characterization and Potential applications

    Författare :Yvonne Hed; Michael Malkoch; Mats Andersson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; AB2C monomer; Click chemistry; CuAAC; thiol-ene coupling chemistry; TEC; linear dendritic hybrids; micelle; hydrogel; bone adhesive;

    Sammanfattning : The development of materials for advanced applications requires innovative macromolecules with well-defined structures and the inherent ability to be tailored in a straightforward manner. Dendrimers, being a subgroup of the dendritic polymer family, possess properties which fulfill such demands. LÄS MER

  5. 19. [11C]Carbon Monoxide in Palladium- / Selenium-Promoted Carbonylation Reactions : Synthesis of 11C-Imides, Hydrazides, Amides, Carboxylic Acids, Carboxylic Esters, Carbothioates, Ketones and Carbamoyl Compounds

    Författare :Farhad Karimi; Kalman Szabo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : [11C]Carbon monoxide in low concentrations has been used in palladium- or seleniummediated carbonylation reactions such as the synthesis of 11C-imides, hydrazides, amides, carboxylic acids, esters, carbothioates, ketones and carbamoyl compounds.In these reactions aryl iodides have been used in most cases.

  7. 20. Control of fatty acid utilization in brown adipose tissue

    Författare :Jan Nedergaard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In order to keep warm in cold surroundings, mammals have developed a mechanism for non-shivering thermogenesis. The major part of this heat production takes place in brown adipose tissue. The heat results from combustion of fatty acids. LÄS MER
