Novel Fabrication and Characterization Methods for Conducting Polymer Nanostructures and Microstructures
To develop devices based on conducting polymers for the benefit of humanity - such as, for example, artificial muscles and lab-on-a-chip diagnostics - we require the ability to reliably fabricate and understand these materials at the micro and nano scales. In this thesis I present research towards …

New Approaches to the Synthesis of Porous and/or High Surface Area Transition Metal Oxides
… The problems related with the dynamics of polymeric nanostructures for the synthesis of predesigned mesostructures could be avoided by crosslinking micelles, strictly speaking non-continuous phase in the bulk structure. Thereby, we presented a new approach for the grafting of Keggin POMs …
