  1. 11. Study and empirical modelling of recrystallisation annealing of martensitic chromium steel strip by means of EBSD

    Författare :Sorin Ionescu-Gabor; KTH; []
    Nyckelord :EBSD; Etching; Metallography; Cold Rolling; Recrystallisation annealing;

    Sammanfattning : Recrystallisation annealing, a repeated heat treatment between different stages of cold rolling of martensitic chromium steel strip, is successful when neither high rolling forces nor wear of the working rolls occur during the subsequent cold rolling. Mechanical properties as tensile strength, yield, elongation or hardness have been, by tradition, the criteria that described the quality of the annealing process. LÄS MER

  3. 12. Monolithic separation media synthesized in capillaries and their applications for molecularly imprinted networks

    Författare :Julien Courtois; Knut Irgum; Ruth Freitag; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bupivacaine; etching; phosphorylated tyrosine; poly ethylene glycol ; silanization; transmission electron microscopy; fused silica capillaries; isothermal titration calorimetry; local anæsthetic; molecularly imprinted polymer; monolith; nuclear magnetic resonance; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The thesis describes the synthesis of chromatographic media using several different approaches, their characterizations and applications in liquid chromatography. The steps to achieve a separation column for a specific analyte are presented. The main focus of the study was the design of novel molecularly imprinted polymers. LÄS MER

  4. 13. Adhesive Wafer Bonding for Microelectronic and Microelectromechanical Systems

    Författare :Niklaus Frank; KTH; []
    Nyckelord :adhesive; wafer; bonding; low temperature; CMOS compatible; selective; local; polymer; thermoplastic; thermosetting; intermediate layer; coating; benzocyclobutene; BCB; photoresist; epoxy; glue; wafer-level; sacrificial; etching; grinding; etch-stop;

    Sammanfattning : Semiconductor wafer bonding has been a subject of interestfor many years and a wide variety of wafer bonding techniqueshave been reported in literature. In adhesive wafer bondingorganic and inorganic adhesives are used as intermediatebonding material. LÄS MER

  5. 14. Case Studies in Ion Beam Assisted Nanostructure Engineering

    Författare :Rajdeep Kaur; Petter Ström; Daniel Primetzhofer; Tuan Tran; Naureen Ghafoor; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ion irradiation; material modification; nanostructures; calcium fluoride; polyimide; etching; Fysik; Physics;

    Sammanfattning : Beams of energetic ions can be used for material analysis and modification. It provides us with a tool featuring unique control over the area, depth and amount of damage in the material. This property of ion beams can be used to generate desired changes in material properties or form nanostructures with specific characteristics in the material. LÄS MER

  7. 15. Arvet efter surrealismen : Grafikskolan Forum 1964-1991

    Författare :Kristina Mezei; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Art history; printmaking; prints; chance; automatism; surrealism; etching; engraving; Imaginism; creativity; 20th century art; Cobra; Breton; Lundberg; Hayter; Konstvetenskap; Art; Konstvetenskap; History Of Art; konstvetenskap;

    Sammanfattning : The dissertation examines Grafikskolan Forum, the Forum School of Printmaking in Malmö, Sweden, and its roots in the surrealist inspired view of the artistic creative process that focused upon automatism, chance events and accidents. The point of departure is the thoughts on artistic creativity of the leader of French surrealism, André Breton. LÄS MER
