  1. 11. Towards improvement of geometrical quality for manual assembly parts

    Författare :Mikael Rosenqvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calculation model; geometry system; Interview; assessment; action cost.; assembly; error; ergonomics; assembly complexity; design for assembly; robust design; complexity; manual assembly; sustainable; tolerance analysis and design; CAT; quality; failure; action cost; assembly ergonomics;

    Sammanfattning : Geometrical variation affects all mass-produced products. This variation will lead to deviations from the nominal design of the product both in terms of aesthetical and functional properties. Geometrical variation originates either from the manufacturing of the parts or from the assembly process.

  3. 12. Development and Characterization of Reliable Graphene-based Materials for Lightweight and Efficient Thermal Management in Electronics

    Författare :Markus Enmark; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat spreader; vapor chamber; thermal management; thermal interface material; wick structure; reliability testing; graphene;

    Sammanfattning : The semiconductor industry continuously aims to increase the transistor density in integrated circuits to improve performance of electronics. As performance and transistor density increases, so does the power density of integrated circuits. LÄS MER

  4. 13. Nanoscale studies of the atmospheric corrosion of copper protected by ultrathin organic films

    Författare :Weijie Zhao; C. Magnus Johnson; Christopher Leygraf; Guido Grundmeier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric corrosion; copper; corrosion inhibition; Langmuir-Blodgett LB deposition; self-assembly deposition; nano-FTIR; octadecylphosphonic acid ODPA .; Kemi; Chemistry;

    Sammanfattning : Copper (Cu) has been utilised by humans for millenniums and has become an indispensable metal in modern industry and in our infrastructure. However, corrosion, as a natural process for metallic materials, takes place on copper surfaces in most environments. LÄS MER

  5. 14. En företagsmodell för modernt industriellt byggande

    Författare :Robert Gerth; Bengt Lindberg; Lars Stehn; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing engineering; Produktionsteknik;

    Sammanfattning : Industrial housing is the strategy of the future for efficient housing. The strategy exploits the principles and work methods of production systems and is applied to the construction industry. Traditionally the construction sector considers production of one-of-a-kind products as de facto solutions. LÄS MER

  7. 15. Direct Amino Acid-Catalyzed Enantioselective α-Oxidation Reactions and Asymmetric de novo Synthesis of Carbohydrates

    Författare :Magnus Engqvist; Armando Cordova; Christina Moberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organo catalysis; Organic chemistry; Organisk kemi;

    Sammanfattning : The ability of amino acids to form nucleophilic enamines with aldehydes and ketones has been used in the development of asymmetric α-oxidation reactions with electrophilic oxidizing agents. Singlet molecular oxygen has for the first time been asymmetrically incorporated into aldehydes and ketones, and the products were isolated as their corresponding diols in good yields and ee’s.
