1. 1. Synthesis of carbon-covered iron nanoparticles by photolysis of ferrocene

   Författare :Karine Elihn; Knut Deppert; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; iron; carbon; nanoparticle; ferrocene; laser-assisted CVD; particle size; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : One important driving force in nanotechnology today is the change which can be made in the properties of a material when the dimensions of its individual building blocks are decreased below approximately 100 nm. Such small building blocks, typically nanoparticles, may induce new and unique properties compared to those of the corresponding bulk material. LÄS MER

3. 2. BIOACTIVE ORGANOMETALLIC COMPOUNDS

   Författare :Haris Bjelosevic; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological; kinetic; gold; platinum; bioactive; phosphine; ruthenocene; Ferrocene;

   Sammanfattning : Various metal complexes have been used in medicine traditionally, although their use was often connected with mystery and with a lack of empirically (clinically) proven effect. In modern times, the development of biochemistry, bioinorganic and bioorganometallic chemistry allows us more in-depth understanding of biological action of metal containing substances. LÄS MER

4. 3. Alternative Redox Couples for Dye-Sensitized Solar Cells

   Författare :Sandra Feldt; Anders Hagfeldt; Gerrit Boschloo; Petra Cameron; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; redox mediator; triphenylamine; cobalt; ferrocene; titanium dioxide; regeneration; recombination; Physical Chemistry; Fysikalisk kemi;

   Sammanfattning : Dye-sensitized solar cells (DSCs) convert sunlight to electricity at a low cost. In the DSC, a dye anchored to a mesoporous TiO2 semiconductor is responsible for capturing the sunlight. LÄS MER

5. 4. Asymmetric Synthesis and Mechanistic Studies on Copper(I)-Catalyzed Substitution of Allylic Substrates

   Författare :Jakob Norinder; Jan-Erling Bäckvall; Norbert Krause; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; copper; allylic substitution; ferrocene; DYKAT; cross-coupling; homo-coupling; DFT; Organic chemistry; Organisk kemi;

   Sammanfattning : This thesis deals with the copper-catalyzed substitution of allylic substrates.In the first part of this thesis, the synthesis of a series of metallocenethiolates is described. The thiolates were examined as ligands in the enantioselective copper(I)-catalyzed γ-substitution of allylic acetates. LÄS MER

7. 5. Carbon Nanostructures – from Molecules to Functionalised Materials : Fullerene-Ferrocene Oligomers, Graphene Modification and Deposition

   Författare :Michael Nordlund; Helena Grennberg; Mogens Brøndsted Nielsen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fullerenes; Graphene; Deposition; Functionalization; Organometallic complexes; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

   Sammanfattning : The work described in this thesis concerns development, synthesis and characterisation of new molecular compounds and materials based on the carbon allotropes fullerene (C60) and graphene.A stepwise strategy to a symmetric ferrocene-linked dumbbell of fulleropyrrolidines was developed.
