  2. 1. Theoretical Modeling and Near-Infrared Spectroscopy Monitoring of Vial Lyophilization

    Author : Mikael Brülls; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-situ; simulation; monitoring; spectral peak area analysis; near-infrared spectroscopy; lyophilization; moisture; sublimation; vial; mathematical model;

    Abstract : The research documented in this thesis was directed towards lyophilization of pharmaceuticals in vials (vial lyophilization) and it was focused on the design and control of this process. Theoretical modeling has considerable potential to guide experimental studies, thereby decreasing development time and improving the possibilities to achieve an optimal and robust process design.

  4. 2. Formic acid adsorption and photodecomposition on rutile TiO2 (110) : An in situ infrared reflection absorption spectroscopy study

    Author : Andreas Mattsson; Lars Österlund; Gunnar Niklasson; Claes-Göran Granqvist; Håkan Rensmo; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : TiO2 based photocatalysis is an emerging green nanotechnology that can be used forremoval of pollutants from water and air. It has had an increased research interest, bothfrom an application and fundamental point of view, during the last decades. READ MORE

  5. 3. The initial atmospheric corrosion of copper and zinc induced by carboxylic acids : Quantitative in situ analysis and computer simulations

    Author : Harveth Gil; Christofer Leygraf; Johan Tidblad; Stuart Lyon; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atmospheric corrosion; copper; zinc; carboxylic acids; modeling; GILDES; in situ; quantification;

    Abstract : Degradation of metals through atmospheric corrosion is a most important and costly phenomenon with significant effects on, e.g., the lifespan of industrial materials, the reliability of electronic components and military equipment, and the aesthetic appearance of our cultural heritage.

  6. 4. Quantitative laser diagnostics of gas-phase potassium species in biomass combustion and gasification

    Author : Emil Thorin; Florian Schmidt; Markus Broström; Zhongshan Li; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical conversion; pyrolysis; phosphorus; single pellet; entrained-flow; in situ; spectroscopy; photofragmentation; imaging; numerical modelling; fysik; Physics;

    Abstract : Thermochemical energy conversion processes, such as combustion and gasification, are applied worldwide for generation of electricity, heat and synthesis of chemicals. Today, these processes are mostly run on non-renewable, fossil fuels and constitute a major source of carbon dioxide emissions. READ MORE

  7. 5. Carved Mountains and Moving Stones : applications of Near Infrared Spectroscopy for Mineral Characterisation in Provenance Studies

    Author : Claudia Sciuto; Johan Linderholm; Paul Geladi; Rachel Opitz; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; Raw materials; mineral characterization; material agency; Near Infrared spectroscopy; hyperspectral imaging; Energy-Dispersive X-ray Fluorescence; multivariate statistics;

    Abstract : The study of stone artefacts is a combination of anthropological archaeology and geology, rooted in analytical techniques for determining the materials’ composition, typological stylistic classification and interpretation of cultural patterns. In this thesis, the archaeology of materials is considered in the context of sites- and landscape transformation, economic history and development of techniques. READ MORE
