  1. 11. Design and stereoselective syntheses of Phe-Phe dipeptidomimetics

    Författare :Annika Jenmalm Jensen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Organic Pharmaceutical Chemistry; organisk farmaceutisk kemi;

    Sammanfattning : Several stereochemically well characterized Phe-Phe dipeptidomimetics have been designed and synthesized. The Phe-Phe vinyl isostere was used as a key intermediate. The synthesized series of mimetics includes two isomeric epoxides, four 1,2-dihydroxyethylene isomers, two isomeric allylic alcohols and two isomeric allylic fluorides. LÄS MER

  4. 13. Structure, interactions and functionality in novel electrolyte materials for fuel cell applications

    Författare :Anna Martinelli; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proton conductivity; ionic liquids; Polymer electrolyte membrane PEM ; fuel cell; vibrational spectroscopy;

    Sammanfattning : It is today well known that fossil fuels will sooner or later be depleted, and the need to find alternative energy sources is now accepted. Among the diverse technologies developed to produce energy, considerable interest is currently directed to the hydrogen fuel cell, a device that converts chemical into electrical energy, is versatile and has a low environmental impact.
