1. 1. Nanoparticle-based capillary electrochromatography

   University essay from Lunds universitet/Kemiska institutionen

   Author : Atef Mannaa; [2013]
   Keywords : PSP-CEC; UV; MALDI-TOF MS; Chemistry;

   Abstract : In this work, lipid nanoparticles were used as pseudostationary phase, PSP, for protein separation in capillary electrochromatography, CEC. The aim of the work was to use a new analytical separation technique for future analysis of protein drugs by using lipid nanoparticles as a pseudo-stationary phase with conventional UV-detection.

   Author : Atef Mannaa; [2012]
   Keywords : Analytisk kemi; Chemistry;

   Abstract : MMP13 (Collagenase 3) is a member of the matrix metalloproteinase (MMP) family. In pathology it is overexpressed in rheumatoid arthritis (RA), osteoarthritis (OA) and human carcinomas. It is secreted in its inactive proforms from which it can be activated. READ MORE

4. 3. Synthesis and characterization of transition metal carbonyl clusters with chiral ligands and their application in asymmetric catalysis

   University essay from Lunds universitet/Kemisk fysik

   Author : Atef Mannaa; [2010]
   Keywords : inorganic chemistry; oorganisk kemi; Chemistry;

   Abstract : Triruthenium dodecacarbonyl was reacted with the non chiral ligand PSSP as well as chiral ferrocenyl diphosphines of the Josiphos (J008, J006 and J015) and Walphos (W009) families to give [Ru3(CO)10(µ-1,2-P-P)], (P-P = W009 1, J008 2, J006 3, J015 4 and PSSP 5. The X-ray structure of 3 shows that a Ru-Ru edge is bridged by a diphosphine ligand in an equatorial coordination mode. READ MORE
