2. Localized corrosion of stainless steels in chlorine dioxide bleach filtrate solutions
Sammanfattning : Stainless steels are extensively used in pulp bleach plantsbecause of their high corrosion resistance. However, alsostainless steels might suffer from corrosion and in bleachplants this is a problem. LÄS MER
3. Prevention of barium sulfate deposition in a D (Chlorine Dioxide) - stage : a chemical model

4. Porous Cerium Dioxide for Catalytic Applications
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. Molecular Beam Studies of Interactions Between Ice Surfaces and Atmospherically Relevant Molecules
Sammanfattning : The discovery of the ozone hole over Antarctica in 1985 was one of the environmental issues that attracted most attention worldwide in the end of the last century. The cause of the ozone hole formation was proven to be coupled to the emission of chlorofluorocarbons (CFCs). LÄS MER
