Sammanfattning : AbstractDuring operation of a fourth generation reactor system it is necessarily not desirable to utilize an oxide fuel matrix as in light water reactor systems. One type of chemical compounds that has been suggested is nitride based nuclear fuel. LÄS MER
Sammanfattning : Contamination of surface and ground water from industrial wastes and anthropogenic activities represents one of the greatest challenges to the sustainable development of human society. Heterogeneous photocatalysis, a kind of advanced oxidation process characterized by the production of highly oxidative hydroxyl radicals, is a relatively novel subject with tremendous potential in water treatment applications.

3. Silver Alumina Catalysts for Lean NOx Reduction - Influence of Preparation Methods and Type of Reductant, with Transient Kinetic Modelling
Sammanfattning : The objective of this work was to compare three different preparation methods for silver alumina catalysts for lean NOx reduction. Characteristics such as catalytic activity with propene and n-octane as reductants, chemical state of the silver and silver dispersion were analyzed. LÄS MER
4. Towards more selective sorbents for extraction of drugs and biomarkers from biological fluids using molecularly imprinted polymers
Sammanfattning : Sample preparation has a critical role as a first step in analytical processes, especially in bioanalysis and environmental analysis. A good sample preparation technique should be robust and stable, regardless of the sample matrix. LÄS MER
Sammanfattning : Recent rapid development of electronics and electro-optical devices demands affordable and reliable materials with enhanced performance. Forming nanocomposites of already well-known materials is one possible route towards novel functional materials with desirable synergistic enhanced properties. LÄS MER
