  1. 1. Exploring expandable microspheres as a novel pore former in gel-cast macroporous alumina

    Författare :Linnéa Andersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gel casting; macroporosity; Al2O3; near-net shape; expandable microspheres; layer-by-layer adsorption; polyelectrolyte; multilayer; colloids; X-ray micro-computed tomography; Lab CT; Organic chemistry; Organisk kemi;

    Sammanfattning : Expandable microspheres have been explored as sacrificial templates for the production of macroporous ceramics. Concentrated alumina powder suspensions that contain expandable microspheres have been consolidated by gel-casting. LÄS MER

  3. 2. Shaping Macroporous Ceramics : templated synthesis, X-ray tomography and permeability

    Författare :Linnéa Andersson; Lennart Bergström; Ludwig Gauckler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alumina; ceramic; CO2 capture; colloidal processing; expandable microspheres; gel casting; layer-by-layer; macroporosity; near-net shape; non-destructive evaluation; permeability; porosity; sacrificial templating; X-ray computed tomography; Chemistry; Kemi; Materials Chemistry; materialkemi;

    Sammanfattning : Macroporous ceramic materials have found widespread technological application ranging from particulate filters in diesel engines, tissue engineering scaffolds, and as support materials in carbon capture processes. This thesis demonstrates how the pore space of macroporous alumina can be manipulated, analysed in three-dimensions (3D) using visualisation techniques, and functionalised with a CO2-adsorbing material.

  4. 3. Towards Visual Literacy in School : Interactions between Students and Interactive Visualizations in Social Science Classrooms

    Författare :Ulrika Bodén; Linnéa Stenliden; Jörgen Nissen; Annika Lantz-Andersson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Design-based research; Interactive visualizations; Knowledge visualizations; Multimodality; Social science education; Socio-materiality; Visual analytics; Visual literacy; Designbaserad forskning; Interaktiva visualiseringar; Kunskapsvisualiseringar; Samhällsorienterande undervisning; Socio-materialitet; Visuell litteracitet;

    Sammanfattning : This compilation thesis explores how the double aspect of visual literacy is enacted in secondary schools’ social science classrooms when interactive data visualizations are employed. The aim is to map what characterizes ‘reading’ interactive data visualizations and ‘writing’ knowledge visualizations, as well as implications for a didactic design supporting students’ visual literacy.

  5. 4. Social determinants in asthma : population-based studies on asthma and respiratory symptoms in relation to occupation, occupational exposure and socioeconomic status

    Författare :Christian Schyllert; Anne Lindberg; Eva Rönmark; Martin Andersson; Magnus Ekström; Linnea Hedman; Ernst Omenaas; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asthma; Signs and Symptoms; Respiratory; Social Determinants of Health; Socioeconomic Factors; Epidemiology; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Background: Asthma is one of the most common chronic obstructive airway diseases among children and adults, with a prevalence between 6-11% in European countries. It is also the most common work-related occupational respiratory disease. LÄS MER
