  1. 1. Additive manufacturing of fused silica glass

    Författare :Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; 3d printing; additive manufacturing; glass; fused silica; laser; scattering; silica; Optik och fotonik; Optics and Photonics; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. LÄS MER

  4. 3. 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

  5. 4. Method development for affinity capillary electrophoresis of ß2-glycoprotein I and biological ligands

    Författare :Maria E. Bohlin; Lars G Blomberg; Niels H H Heegaard; Jan Leo Reubsaet; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Capillary Electrophoresis; β2-glycoprotein I; acidic pretreatment; pH hysteresis effect; Affinity Capillary Electrophoresis; Kemi; Chemistry;

    Sammanfattning : The final goal of this study is to establish a microscale analysis method that allows solution phase characterization of interactions between β2-glycoprotein I (β2gpI) and some of its ligands. Human β2gpI is a phospholipid- and heparin-binding plasma glycoprotein. LÄS MER

  7. 5. Time resolved laser studies of gas phase and condensed phase molecules

    Författare :Cecilia Lundevall; Indrek Martinsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : Different laser based techniques have been used to study lifetimes and spectra of gas phase molecules, and non-linear optical phenomena in condensed phase materials.The lifetimes of several electronically excited states of the diatomic molecules vanadium oxide, VO, zirconium sulphide, ZrS, titanium sulphide, TiS and titanium oxide, TiO have been performed by resonant two-photon ionisation spectroscopy in a molecular beam combined with a time of flight mass spectrometer.
