1. New Fullerene Materials Obtained in Solution and by High Pressure High Temperature Treatment
Sammanfattning : Crystallization of C60 and C70 from organic solution often leads to the formation of new solvates and other fullerene compounds. In the present thesis, a number of such solvates were obtained and their phase transitions studied using in situ "in solution" techniques. LÄS MER
2. Implementation of MRI gel dosimetry in radiation therapy
Sammanfattning : Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. LÄS MER
3. Epoxides as Contact Allergens - Formation, Sensitising Potency and Structure-Activity Relationships
Sammanfattning : Chemicals in our environment with which we have repeated skin contact can cause skin sensitisation (contact allergy). To trigger an immune response a compound (hapten) must be able to penetrate the skin, where it needs to be reactive enough to bind to proteins and form immunogenic complexes that are recognised as foreign.

4. Towards the Rational Design of Molecularly Imprinted Polymers
Sammanfattning : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. LÄS MER
5. Responsive Molecular Systems through Dynamic Covalent Chemistry
Sammanfattning : Nature tends to inspire research in chemistry. Systems that emerge from molecules interacting via reaction networks is something that life has mastered over the course of evolution in order to produce complexity. Dynamic reactions are key in systems chemistry, where reaction networks give rise to complex, emergent behavior. LÄS MER
