  1. 1. Carbon Nitride : Characterization and Protein Interactions

    Författare :Torun Berlind; Hans Arwin; Pentti Tengvall; Hans Hultman; Thomas E. Tiwald; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis concerns synthesis and characterization of carbon-based materials and theinvestigation of the possible use, of a selection of these materials, in biomedicalapplications. Protein adsorption and blood plasma tests were used for this purposeutilizing a surface sensitive technique called spectroscopic ellipsometry. LÄS MER

  3. 2. Optical Studies of Bio-inspired Materials for Camouflage

    Författare :Christina Åkerlind; Kenneth Järrendahl; Hans Arwin; Hans Kariis; Karin Stein; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the ongoing sensor-camouflage duel, new functionalities and sensing abilities are continuously incorporated in detector devices, requiring new capabilities on the camouflage side. The aim of this work is to contribute to improved camouflage including low polarization detectability in wavelength regions with both visible and invisible light. LÄS MER

  4. 3. Optical Studies of Materials for Spectral Design

    Författare :Christina Åkerlind; Kenneth Järrendahl; Hans Arwin; Hans Kariis; Isak Engquist; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Optical material properties have been studied in a wide wavelength range. Theaim is future use of spectral design for camou age. The main characterization techniques used in this work are Refection Spectroscopy, Scatterometry (BRDF) and Mueller Matrix Ellipsometry. LÄS MER

  5. 4. Optical Detection Using Computer Screen Photo-assisted Techniques and Ellipsometry

    Författare :Jimmy W. P. Bakker; Hans Arwin; Jin Gang; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical sensing; Biohttps: www.diva-portal.org liu webform form.jsp#paper0sensing; Ellipsometry; Computer Screen Photo-assisted Technique; Fluorescence; Immunoassays; Optics; Optik;

    Sammanfattning : Two main subjects, ellipsometry and computer screen photo-assisted techniques (CSPT), form the main line in this thesis. Ellipsometry is an optical technique based on the detection of polarization changes of light upon interaction with a sample. LÄS MER

  7. 5. Optical and Structural Characterization of Natural Nanostructures

    Författare :Lía Fernández del Río; Kenneth Järrendahl; Hans Arwin; Arturo Mendoza-Galván; Dimitri Deheyn; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The spectacular biodiversity of our planet is the result of millions of years of evolution. Over this time animals and plants have evolved and adapted to different environments, developing specific behavioral and physical adaptations to increase their chances of survival. LÄS MER
