  1. 1. Atmospheric corrosion of Mg and MgAl alloys – characterization and mechanisms

    Författare :Mehrdad Shahabi Navid; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDX; CO2; XPS; Mg and MgAl alloys; NaCl; Atmospheric corrosion; Characterization; 3D imaging; SEM; BIB; Thin film; FTIR; XRD; Pitting; Interference microscopy; FIB;

    Sammanfattning : The atmospheric corrosion of Mg and MgAl alloys was investigated. Corrosion tests were performed in the laboratory under controlled environment. CP Mg, AM50 and AZ91 samples were exposed at 95% RH and 22°C in the presence and in the absence of 400 ppm CO2 for 24 h to 672 h. The passive film was characterized by means of XPS, FTIR, AES and XRD. LÄS MER

  2. 2. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites

    Författare :Jasna Stevanic Srndovic; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic FTIR spectroscopy; viscoelasticity; orientation; Norway spruce; protein; glucomannan; xyloglucan; polymer interactions; pectin; imaging FTIR microscopy; primary cell wall; nanocomposite films; dynamic 2D FTIR spectroscopy; xylan; wood fibre; cellulose; secondary cell wall; DMA; lignin;

    Sammanfattning : A wood fibre is a complex multi component biocomposite that is hierarchically organised. The arrangement of a wood fibre on the ultrastructural level is highlycontrolled by the interactions between the main structural polymers, i.e. cellulose, various hemicelluloses and lignin, as well as in some parts also pectin and protein.

    Sammanfattning : The objects of this PhD thesis are Southern Swedish painted wall-hangings: folk art paintings from the 18th and 19th centuries. The aim and objective of the study are: to investigate the construction and manufacturing processes of the painted wall-hangings; to identify both the painting materials and other substances employed; and, to document painting techniques used by different painters within this painted wall-hanging tradition.

  4. 4. Drugs and polymers in dissolving solid dispersions NMR imaging and spectroscopy

    Detta är en avhandling från Stockholm : KTH

    Författare :Carina Dahlberg; KTH.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; NATURAL SCIENCES Chemistry Physical chemistry Surface and colloid chemistry; NATURVETENSKAP Kemi Fysikalisk kemi Yt- och kolloidkemi; PHARMACY; FARMACI;

    Sammanfattning : The number of poorly water-soluble drug substances in the pharmaceutical pipeline is increasing, and thereby also the need to design effective drug delivery systems providing high bioavailability. One favourable formulation approach is preparation of solid dispersions, where dispersing a poorly water-soluble drug in a water-soluble polymer matrix improves the dissolution behaviour and the bioavailability of the drug.

  5. 5. Application of Vibrational Spectroscopy in Organic Electronics

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Mohammad Javad Jafari; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The rapid technological developments enforce us to live in an increasingly electronic world, and the revolutionary usage of conjugated polymers in electronics in the late 1970s accelerated these developments, based on the unique characteristics of conjugated polymers, such as low cost, easy processing, mechanical flexibility, large-area application and compatibility with a variety of substrates. Organic electronic devices are commercially available in the form of, for example, solar cells, transistors, and organic light-emitting diode (OLED) displays. LÄS MER
