  1. 21. Structure evolution of phase-separated EC/HPC films for controlled drug release

    Author : Pierre Carmona; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electron microscopy; coarsening; cellulose; phase separation kinetics; drug delivery; phase separation mechanisms; porous film; biopolymer; controlled drug release; confocal laser scanning microscope; spin-coating.;

    Abstract : Porous phase-separated ethylcellulose/hydroxypropylcellulose (EC/HPC) films are used to control drug transport out of pharmaceutical pellets. The drug transport rate is determined by the structure of the porous films that are formed as the water-soluble HPC leaches out. READ MORE

  2. 22. Advanced Optical Diagnostics in Particle Combustion for Biomass and Metal as Alternative Fuels

    Author : Shen Li; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics; Quantitative measurement; Iron powder; Biomass; High-speed imaging; Digital holography; 3D reconstruction; SEM; Fysicumarkivet A:2022:Li;

    Abstract : The energy sector is in urgent need for carbon-free strategies considering environmental pollutions and climate change impact. Two kinds of solid fuels, biomass and metal particles have been studied in this thesis aiming at CO2 emission reduction or zero carbon emission. READ MORE

  3. 23. Phenomena in wire based multi-layer laser welding and hybrid deposition

    Author : Jonas Näsström; Alexander Kaplan; Frank Brueckner; Sven Bengtsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Abstract : Several laser materials processing technologies using metal wire addition have been researched during the last decades. Especially in the field of joining, as well as in the field of Additive Manufacturing (AM), multiple major benefits have been reached, e.g. higher welding speeds and lower heat input. READ MORE

  4. 24. Estimation of forest parameters using 3D satellite data : stereogrammetry, radargrammetry and interferometry

    Author : Henrik Persson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Accurate data about the forest are needed both in climate research and forest management planning. This thesis focuses on using different types of three-dimensional (3D) satellite data sources to accurately estimate forest variables, primarily above-ground biomass (AGB) and tree height (H).

  5. 25. On the bone response to different implant textures. A 3D analysis of roughness, wavelength and surface pattern of experimental implants

    Author : Carin Hallgren Höstner; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surface modification; surface texture; roughness; surface evaluation; in vivo studies.;

    Abstract : PurposeThe purpose of the present thesis was to investigate the bone response to different isotropic, anisotropic and organised surface patterns.Material and methodsImplant surfaces have been modified with different techniques (abrasive blasting, turning, milling, photolithography or laser ablation).
