6. Synthesis of Zeolites from Bolivian Raw Materials for Catalysis and Detergency Applications
Sammanfattning : Zeolites are very useful in many technological applications such as catalysis, separation and purification of gases and solvents, ion-exchange, etc. The production of zeolites is nowadays carried out with a variety of reagents, such starting materials render large scale production of zeolites expensive.

7. Surface Reactions During Atomization, Handling and Consolidation of Al-powders
Sammanfattning : Surface reactions during atomization and consolidation of pure Al and the alloys Al2Mg, Al5Mn2.5Cr, Al5Mn6Cr and Al8Fe2Mo were studied by using ESCA, SAM and SEM. The powders were analysed in the as-atomized condition and after exposure to humid atmosphere. The powders were atomized by using the USGA (Ultra Sonic Gas Atomization)-technique. LÄS MER
8. Synthesis and applications of low silica zeolites from Bolivian clay and diatomaceous earth
Sammanfattning : The aim of the present work was to develop synthesis routes to produce synthetic zeolites with industrial attractiveness from non-expensive Bolivian raw materials, such as clays and diatomite. In particular, the work was focused on the synthesis of low-silica zeolites with the LTA and FAU structures. LÄS MER
9. Degradation of acrylonitrile butadiene rubber and fluoroelastomers in rapeseed biodiesel and hydrogenated vegetable oil
Sammanfattning : Biodiesel and hydrotreated vegetable oil (HVO) are currently viewed by the transportation sector as the most viable alternative fuels to replace petroleum-based fuels. The use of biodiesel has, however, been limited by the deteriorative effect of biodiesel on rubber parts in automobile fuel systems. LÄS MER
10. Preparation and Evaluation of New Nanoporous Silica Materials for Molecular Filtration and for Core Materials in Vacuum Insulation Panels
Sammanfattning : Nanoporous materials for gas purification and thermal insulation have been studied and developed for application in many areas. It is known that a single adsorbent may not adequately control multiple contaminants. Further the utilization of nanoporous material as thermal insulator in building applications is limited due to high cost. LÄS MER
