    Abstract : This thesis presents a novel approach to integrate chemical vapor deposition (CVD) graphene into silicon micro- and nanoelectromechanical systems (MEMS/NEMS) to fabricate different graphene based MEMS/NEMS structures and explore mechanical properties of graphene as well as their applications such as acceleration sensing, humidity sensing and CO2 sensing. The thesis also presents a novel method of characterization of CVD graphene grain boundary based defects. READ MORE

  4. 7. Shear walls with double plasterboards : evalutation of design models

    Author : Tomas Filipsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis presents a part of the ECSC-project Development of dry composite construction systems based on steel in residential application that focus on design recommendations for stabilizing buildings by using shear resistance in the walls. The existing design method suggested and used by the Swedish plasterboard manufacturer Gyproc AB is considered as a bit conservative and it does not consider double plasterboards properly. READ MORE

  5. 8. Topographical micro-changes in corrugated board production : effects on flexographic post-print quality

    Author : Marcus Rehberger; Nils Enlund; Gunnar Engström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrugated board; liner; double-facer; double-backer; gloss; surface roughness; micro structure; wear; paper metal friction; flexo; ink-jet; print quality; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The appearance and design of a package are key properties to attract and to focus the attention of a customer. Print quality contributes to a great degree to achieve these requirements. Most critical perceived in terms of quality are print defects like mottling, gloss and stripiness, which all appear in the printing of corrugated board. READ MORE

  6. 9. Nanoscientific investigations of electrode materials for supercapacitors
