1. 11. Development of Second and Third Generation Bioelectronics

   Författare :Federico Tasca; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; flow injection analysis; amperometric biosensor; mediated electron transfer; direct electron transfer; tryptophan repressor-binding protein; diaphorase; pyranose oxidase; cellobiose dehydrogenase; pyranose dehydrogenase; biofuel cell; spectroelectrochemistry; single wall carbon nanotubes; bioelectronics.;

   Sammanfattning : The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”.

3. 12. 3D Integration of Carbon Based Electronics

   Författare :Wei Mu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Carbon-based nanomaterials such as carbon nanotubes (CNTs) and graphene, which possess superior electrical, thermal and mechanical properties, have been proposed as alternative materials for future electronics. The proposed applications span from the device level, replacing silicon-based transistors, with single-walled carbon nanotubes (SWCNTs) or graphene, to packaging level using multi-walled carbon nanotubes (MWCNTs) for interconnects.

   Sammanfattning : In this Ph.D. thesis I present the background and providefurther details to the work presented in the appended papers. The background consists of brief overviews of Kondo physics, Luttinger liquid theory, and conformal field theory. LÄS MER

5. 14. Thermal and mechanical studies of carbon nanotube-polymer composites synthesized at high pressure and high temperature

   Författare :Bounphanh Tonpheng; Ove Andersson; Sylwester J. Rzoska; Umeå universitet; []
   Nyckelord :;

   Sammanfattning : In this thesis, thermal and mechanical properties of polymers and carbon nanotubes-polymer composites, which were modified and studied under high pressure, are presented. The results concern the thermal conductivity κ and heat capacity per unit volume ρcp of pure polymers: polyisoprene (PI), polybutadiene (PB), and nylon-6, and their multi-wall and single-wall carbon nanotube (MWCNT and SWCNT) composites both before (untreated) and after high pressure treatments.

7. 15. Materials for Hydrogen storage and synthesis of new materials by hydrogenation

   Författare :Serhiy Luzan; Alexandr Talyzin; Yaroslav Filinchuk; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fullerene C60; MOFs; CNTs; SWCNTs; PAHs; peapods; hydrogen; hydrogen storage; hydrogenation; adsorption; surface area; pore volume; spillover; nanoribbons; fragmentation; fysikalisk kemi; Physical Chemistry; fysik; Physics;

   Sammanfattning : The search for new materials for hydrogen storage is important for the development of future hydrogen energy applications. In this Thesis, it is shown that new materials with interesting properties can be synthesized by the reaction of hydrogen with various nanocarbon precursors. The thesis consists of two parts. LÄS MER
