  1. 1. Glycoconjugates : synthesis and investigation of carbohydrate-protein interactions

    Author : Sara Spjut; Mikael Elofsson; Ulf Ellervik; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Glycoconjugates; Carbohydrates; Galactose; Glucose; Solid-phase synthesis; SPOS; Glycosylation; Gel-phase 19F NMR spectroscopy; Fluorinated linker; Carbohydrate array; Microtiter plates; Carbohydrate-protein interactions; carbamate linker; Fsec; Protecting group; Fluorinated protecting group; Multivalent glycoconjugates; Adenovirus; Ad37; Epidemic keratoconjunctivitis; EKC; Sialic acid; Adenovirus inhibitor; Trivalent; Tetravalent; X-ray crystal structure; Bioorganic chemistry; Bioorganisk kemi; organisk kemi; Organic Chemistry;

    Abstract : To study the functions of glycoconjugates in biological systems reliable and efficient protocols for glycoconjugate synthesis are needed. To reach this goal we have developed methods for solid-phase synthesis of glycoconjugates that can be monitored with gel-phase 19F spectroscopy using fluorinated linkers, building blocks, and protecting groups.

  2. 2. Tetradentate amide extraction agents for trivalent lanthanides

    Author : Mikhail S Tyumentsev; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; malonamides; lanthanides; solvent extraction; entropic effect; electrospray ionization – mass spectrometry; single-crystal X-ray diffraction;

    Abstract : Lanthanides are valuable materials. They are used in catalysts, permanent magnets, batteries, optical devices, and in many other products. Lanthanides are mainly supplied by mining industry, which generates large volumes of waste due to relatively low concentrations of these elements in geological deposits. READ MORE

  3. 3. Development of Polyamide Solvent Extraction Reagents for Trivalent Lanthanides

    Author : Mikhail S Tyumentsev; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyamides; Solvent Extraction; Europium; Rare Earth Elements; Lanthanides; Malonamides;

    Abstract : Rare earth elements (REEs), including lanthanides, are critical materials for many industrial technologies. As a result recycling of end-of-life products containing REEs might be beneficial, as this could partially satisfy the growing demands of industry for these elements. READ MORE

  4. 4. In-situ activated hydrogen evolution from pH-neutral electrolytes

    Author : John Gustavsson; Ann Cornell; Olof Forsén; KTH; []
    Keywords : molybdate; trivalent cations; electrolysis; hypochlorite reduction; films; electrolysis; chlorate process; molybdat; trivalenta katjoner; elektrolys; hypokloritreduktion; filmer; kloratprocessen; SRA - Energy; SRA - Energi;

    Abstract : The goal of this work was to better understand how molybdate and trivalent cations can be used as additives to pH neutral electrolytes to activate the Hydrogen Evolution Reaction (HER). Special emphasis was laid on the chlorate process and therefore also to some of the other effects that the additives may have in that particular process. READ MORE
