1. 1. Reactions of Model and Anticancer Active Platinum(IV/II) Complexes - A Kinetic and Mechanistic Study

   Författare :Kelemu Lemma; Kemiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Model Pt II complexes; Anticancer active Pt IV compounds; Cisplatin; Rescue agents; L-Ascorbic acid; Thiol; Substitution; Kinetics and mechanism; Electron transfer; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : In this thesis reductions of model and anticancer active Pt(IV) complexes with thiols and ascorbic acid and substitution reactions of cisplatin and model Pt(II) complexes with S-donor nucleophiles (rescue agents) have been investigated using stopped-flow and UV/VIS spectrophotometry. Glutathione (GSH) reduction of the anticancer active Pt(IV) compounds t- and c-[PtCl4(cha)(NH3)] (cha = cyclohexylamine), t-[PtCl4(thiazole)(NH3)] and c-[PtCl4(NH3)2] at 25 oC was observed to be very fast.

3. 2. Towards More Specific Microcalorimetric Studies With Special Emphasis on Biological Systems

   Författare :Peter Johansson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; isothermal heat conduction micro calorimetry spectrophotometry diode array pH oxygen titration chemical reaction biological bacteria perfusion photo carbon dioxide plant enthalpy Gibbs energy kinetic; Biology; Biologi;

   Sammanfattning : A new approach in isothermal heat conduction microcalorimetric studies of chemical and biological processes is explored. The general (non-specific) method of calorimetry is combined with more specific analytical methods of analysis to "multi-functional microcalorimetric process monitors". LÄS MER

4. 3. Graphene Based Inks for Printed Electronics

   Författare :Man Song; Zhi-Bin Zhang; Helena Grennberg; Anwar Ahniyaz; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exfoliation; Graphene inks; Inkjet printing; Screen printing; GO Ag hybrid inks; Leuckart reaction; Reduction.; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : The outstanding properties of graphene make it attractive ink filler for conductive inks which plays an important role in printed electronics. This thesis focuses on the ink formulation based on graphene and graphene oxide (GO).Liquid phase exfoliation of graphite is employed to prepare graphene dispersions, i.e. LÄS MER
