1. 16. Cobalt catalyst supports for Fischer-Tropsch synthesis

   Författare :Fatima Pardo-Tarifa; Lars J. Pettersson; Olga Guerrero; KTH; []
   Nyckelord :Silica; alumina; zirconium; cerium; mesoporous materials; nanoparticles; microemulsion; atrane route; cobalt catalyst; Fischer-Tropsch synthesis; Chemical Engineering; Kemiteknik;

   Sammanfattning : In the Fischer-Tropsch (FT) synthesis, CO and H2 (synthesis gas) are converted into hydrocarbons that can be further upgraded to high-quality fuels and chemicals. Different carbon sources such as natural gas, coal and biomass can be used as feed-stocks for the synthesis gas. LÄS MER

3. 17. Physicochemical and Biopharmaceutical Characterisation of Small Drug Molecules by Capillary Electrophoresis

   Författare :Eivor Örnskov; Staffan Folestad; Karin E. Markides; Morteza Khaledi; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; capillary electrophoresis CE ; micellar electrokinetic chromatography MEKC ; drug; liposome; microemulsion; coating; pKa; lipophilicity; multivariate analysis; molecular descriptor; hierarchical analysis; passiv absorption; Analytisk kemi; Analytical chemistry; Analytisk kemi;

   Sammanfattning : Capillary Electrophoresis (CE) was explored as a means for physicochemical and biopharmaceutical characterisation of small drug molecules. Special attention was paid to the characterisation of acid-base and lipophilic properties of drug compounds by analysing their migration behaviour in different CE systems. LÄS MER

4. 18. Phase Diagrams, Microstructure and Phase Separation in Alkyl Glucoside Systems
