  1. 1. Porous Cerium Dioxide for Catalytic Applications

    Författare :Mats Lundberg; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; materialteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Materiallära; Material technology; catalysis; transmission electron microscopy; macroporous; mesoporous; cerium dioxide; zirconium dioxide;

    Sammanfattning : Mesoporous cerium dioxide with high crystallinity has been synthesized and studied by TEM, SEM, nitrogen adsorption, PXRD, AFM, and SAXS. The catalytic properties of the materials have been investigated The results of the catalysis experiments were correlated with high resolution TEM investigations of the corresponding material, and it was found that the exposed crystallographic facets play an important role in the conversion of carbon monoxide to carbon dioxide.

  5. 4. Kinh Settlers in Viet Nam’s Northern Highlands : Natural Resources Management in a Cultural Context

    Författare :Mats Lundberg; Anders Hjort af Ornäs; Hans Holmén; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Viet Nam; northern mountains; highlands; wet rice agriculture; upland agriculture; shifting cultivation; natural resources use; local knowledge; culture; ethnicity; Naturresurser; Vietnam; etniska grupper; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : This study deals with the Kinh (or Viet) majority people who have migrated from the lowland Red River Delta to the mountainous areas of northern Viet Nam, and their adjustment to a new social and physical environment. Its aim is to analyse the social and cultural consequences for these migrants when settling in communities populated with people who belong to the national ethnic minorities (the Tày, the Giay and the Ngan peoples).

  7. 5. Non-Exhaust PM10 and Road Dust

    Författare :Joacim Lundberg; Sigurdur Erlingsson; Mats Gustafsson; Sara Janhäll; Göran Blomqvist; Brynhild Snilsberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road Dust; Abrasion Wear; Road Surface Macro Texture; Mean Profile Depth; Mean Texture Depth; Emissions; Abrasion Wear Model; NORTRIP; PM10; Air Quality; Particles; Vägdamm; Vägslitage; Dubbslitage; Textur; Emissioner; Slitagemodell; NORTRIP; PM10; Partiklar; Luftkvalitet; Byggvetenskap; Civil and Architectural Engineering; 15 Road: Environment;

    Sammanfattning : Non-exhaust PM10 is an issue in the urban environment linked to health issues. Emissions of non-exhaust PM10 is relatable to pavement properties. Also of importance is resuspension of road dust stored from surfaces. This depends on the traffic and metrological conditions. LÄS MER
