1. Thermoelectric- and hot-electron effects in graphene devices
Sammanfattning : A technology of encapsulation of graphene in Parylene was introducedas an alternative to encapsulating graphene in hBN. Edge contacts to theencapsulated graphene in this case showed resistivity down to 14 Ohm um,which is the lowest reported value so far. LÄS MER
2. A novel implantable ultra-flexible brain machine interface. Manufacturing and initial characterisations
Sammanfattning : This thesis describes for the very first time the development of a miniaturized neural interface which is flexible in three dimensions (3D) to enable it to follow the brain movements with minimal dislocation. Both the design rationale and the material choice for the electrodes aim to develop interfaces that minimize the damage and/or the irritation of the tissue during and after the implantation. LÄS MER
3. Development of highly biocompatible neuro-electronic interfaces towards monitoring authentic neuronal signaling in the brain
Sammanfattning : Background: To understand how the neuronal circuits in the brain process information there is a need for novelneuro-electronic interfaces that can interact chronically with brain tissue with minimal disturbance of thephysiological conditions in the tissue, in awake and freely moving animals. For this, there is a need for implantableneuro-electronic interfaces that are mechanically compliant with the tissue and that can remain positionally stablewith respect to the neurons, despite the continuous micromotions in the brain.

4. Elastic interconnection micro contact stuctures-manufacture and characterisation
Sammanfattning : ...The task that was put to the author of this thesis was to find solutions for manufacturing of single elastic micro bump contacts as well as complete elastic sockets and interconnections down to the carrier substrate. LÄS MER
5. LDI-MS strategies for analysis of polymer degradation products, additives and drugs
Sammanfattning : The advancement of mass spectrometry (MS) has been and continues to be a prominent analytical technique for highly accurate determination of analytes. The goal of this thesis was to develop new laser desorption ionization-mass spectrometric (LDI-MS) methods for analysis of polymer degradation products, additives and drugs. LÄS MER
