1. Fabrication and Functionalization of Graphene and Other Carbon Nanomaterials in Solution
Sammanfattning : In the last decades several new nanostructures of carbon have been discovered, including carbon nanotubes (CNTs), and the recently discovered 2-dimensional graphene. These new materials exhibit extraordinary and unique properties—making them extremely interesting both for fundamental science and for future applications. LÄS MER
2. Functionalized Graphene as Superlattice and Gas Sensor
Sammanfattning : Graphene, an atomic-thin carbon sheet with carbon atoms tightly packed honeycomb-like lattice, has attracted enormous interest due to its unique chemical and physical properties. However, the intrinsic zero bandgap characteristic of graphene has so far prevented graphene from building effective electronic and optoelectronic devices. LÄS MER
3. Functionalization and Characteization of Carbon-based Nanomaterials
Sammanfattning : Surface functionalization of nanomaterials opens up unlimited possibilities to combine the distinct properties of inorganic, organic, or even bioactive components in a single material and bring novel functionalities in a wide range of applications ranging from electronics to catalysts and medicine carriers. So far, a variety of organic and inorganic nanomaterials have been explored to construct different functionalized nanomaterials. LÄS MER
4. Carbon Nanostructures – from Molecules to Functionalised Materials : Fullerene-Ferrocene Oligomers, Graphene Modification and Deposition
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.

5. Development of Mild Methods for Selective Covalent Functionalization of Graphene
Sammanfattning : This thesis discusses methods for the comparatively mild covalent functionalization of graphene. Several graphene models were investigated: polycyclic aromatic hydrocarbons (PAHs), chemical vapor deposition (CVD)-graphene on SiO2/Si substrate, graphite foil, graphite flakes, kish graphite and highly oriented pyrolytic graphite.
