  1. 16. Low temperature transfer bonding for MEMS. Utilizing and characterizing oxygen plasma assisted direct wafer bonding

    Författare :Martin Bring; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transfer bonding; chevron notch; oxygen plasma assisted bonding; Low temperature bonding; fracture toughness;

    Sammanfattning : Transfer bonding enables the integration of devices, e.g. integrated circuits (ICs) and transducers, fabricated using processes and/or designs that are not compatible with each other as well as double sided micromachining of thin films. LÄS MER

  3. 17. Processing Methods for Reaching Full Density Powder Metallurgical Materials

    Författare :Maheswaran Vattur Sundaram; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas atomised powder; water atomised powder; high density powder metallurgical materials; high density; master alloys; liquid phase sintering; sintering; high velocity compaction; hot isostatic pressing; additive manufacturing;

    Sammanfattning : Powder metallurgy (PM) is one of the most cost effective methods for manufacturing structural components with complex shapes. Utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gravitation; relativity; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Fysik; Physics; High peak-to-valley ratio; Lateral confinement; Quantum dots; Resonant tunneling; Self-assembled quantum dots; Schottky depletion; Buried metal gate; Electron transport; Magnetic-field dependence; Energy level width; Tunneling transistors; Mode coupling; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Technological sciences; Teknik; Fysicumarkivet A:2001:Gustafson;

    Sammanfattning : In the thesis, three-dimensionally confined resonant tunneling structures were studied experimentally. Two approaches were used for obtaining quantum confinement: gate-defined lateral constriction of double barrier structures, and epitaxial growth of self-assembled quantum dots. LÄS MER

  5. 19. Numerical and experimental investigation of paperboard creasing and folding

    Författare :Hui Huang; Mikael Nygårds; Nils Hallbäck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Sammanfattning :  This licentiate thesis aims to increase the understanding of deformation and damage mechanisms of paperboard during converting, especially creasing and folding will be analyzed. A simple two dimensional creasing simulation was performed. LÄS MER

  7. 20. Sensitive Forensic DNA Analysis : Application of Pyrosequencing and Real-time PCR Quantification

    Författare :Hanna Andréasson; Marie Allen; Ulf Gyllensten; Pål Nyrén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; forensic; sensitive DNA analysis; DNA quantification; mtDNA; Real-time PCR; Pyrosequencing; Genetik; Clinical genetics; Klinisk genetik;

    Sammanfattning : The field of forensic genetics is growing fast and the development and optimisation of more sensitive, faster and more discriminating forensic DNA analysis methods is highly important. In this thesis, an evaluation of the use of novel DNA technologies and the development of specific applications for use in forensic casework investigations are presented. LÄS MER
