6. Polymer Actuators for Micro Robotic Applications
Sammanfattning : In this thesis a multilayer actuator structure is developed for the I-SWARM project. In order to build an energy efficient and low voltage actuator system for the 3x3x3 mm3 robot, the resonance drive mode in combination with a ten layer multilayer structure build upon the most suitable substrate material was used.

7. Melt spinning of poly(vinylidene fluoride) mono- and bicomponent fibres and yarns : the formation of piezoelectric beta-phase crystallinity
Sammanfattning : The present study investigates the possibilities of manufacturing piezoelectric polymer fibres or yarns for integration into textile materials. The polymers known to give the strongest piezoelectric effects are poly(vinylidene fluoride) (PVDF) and some of its copolymers. LÄS MER
8. Computational studies of Poly(vinylidene fluoride) and Poly(vinylidene fluoride) - Single Wall Carbon Nanotube Composites
Sammanfattning : Poly(vinylidene fluoride) (PVDF) exhibits properties that allows the material to be used in such diverse areas as wire and cable products, electronic devices, membranes, exterior coatings for constructions and in the chemical, pharmaceutical and food industry as fluid-handling equipment. It is the inherent molecular structure of PVDF, where every second backbone carbon is bonded to two fluorine atoms, that gives the polymer several unique properties, among them piezo- and pyroelectricity.

9. Bright and strain-tunable semiconductor quantum dot devices
Sammanfattning : Optically active semiconductor quantum dots have proven to be excellent single- and entangled-photon sources, with applications in quantum optics and quantum photonics. These sources are considered crucial in the development of future photonic quantum technology, such as quantum communication, quantum computation and quantum metrology. LÄS MER
10. 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.
