  1. 1. AlN and High-k Thin Films for IC and Electroacoustic Applications

    Författare :Fredrik Engelmark; Ivan Petrov; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik; Electronics; Elektronik; Elektronik; Electronics;

    Sammanfattning : Further, a highly selective dry etch process for etching Al on AlN has been developed for the fabrication of MIM, MIS, SAW and BAW test structures for electrical and electroacoustic characterization of the films. A dielectric constant of 10 for AlN and 25 for Ti doped Ta2O5 have been measured. LÄS MER

  2. 2. Heat and water flows in freezing and thawing soils : numerical modelling, laboratory and field observations

    Författare :Helén Engelmark; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : A laboratory study of infiltration rates into frozen and unfrozen fine sand, including temperature effects of both soil and infiltration water, is reported. The average infiltration rate varied from about 10.6 mm/min for unfrozen conditions, to about 1-2 mm/min for frozen conditions. LÄS MER

  4. 4. Tools in biocatalysis : enzyme immobilisation on silica and synthesis of enantiopure amines

    Författare :Karim Engelmark Cassimjee; Per Berglund; Torkel Berglund; Torbjörn Gräslund; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents two techniques in the field of biocatalysis: An enzyme immobilisation method based on the His6-tag for attachment on modified silica oxide beads, and it’s employment in aqueous and organic medium for synthesis applications. The method functions as a one step extraction and immobilisation protocol. LÄS MER

  5. 5. ω-Transaminase in Biocatalysis : Methods, Reactions and Engineering

    Författare :Karim Engelmark Cassimjee; Per Berglund; Wofgang Kroutil; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Biocatalysis offers an alternative to classic chemistry by using enzymes, the protein catalysts of Nature, for production of fine chemicals. Evolution has created enzymes capable of catalysis at moderate temperature of a specific reaction in the presence of a plethora of compounds in the aqueous cell environment. LÄS MER
