7. Corrosion initiation induced by sodium sulfate and sodium chloride particles on Cu and the golden alloy Cu5Al5Zn at simulated atmospheric conditions
University essay from KTH/MaterialvetenskapAbstract : Effects of sodium sulfate (Na2SO4) particle deposition on the atmospheric corrosion of copper (Cu) metal and a Cu-based alloy (Cu5Al5Zn) used in architectural applications were investigated at laboratory conditions compared with effects induced by sodium chloride (NaCl) and to some extent ammonium sulfate (NH4)2SO4 induced corrosion. Pre-deposited surfaces were exposed to repeated wet/dry conditions in a climatic chamber and the formation of corrosion products were assessed using light optical microscopy (LOM), scanning electron microscopy with elemental analysis (SEM/EDS), Fourier transform infrared techniques (FTIR microscopy) and cathodic reduction (CR).

9. Growth and phosphorus uptake of potato (Solanum tuberosum L.) in an alkaline soil as affected by mineral nitrogen forms and inoculation with phosphate-solubilizing bacteria and mycorrhizal fungi
University essay from SLU/Dept. of Biosystems and Technology (from 130101)Abstract : In soils with relatively high pH (pH > 7), potatoes (Solanum tuberosum L.) and other phosphorus (P) demanding crops might suffer from P deficiency despite P fertilization and significant reserves of P in the soil. Also, a high risk for P deficiency for potatoes may be expected when the soil is cold and the root system undeveloped. READ MORE

10. Livscykelanalys av behandlingsprocesser för flygaska från avfallsförbränning : jämförelse av Ash2Salt-processen med befintliga metoder
University essay from SLU/Dept. of Energy and TechnologyAbstract : EasyMining Sweden AB, a subsidiary to Ragn-Sells AB, has developed a new process for treatment of fly ash from municipal solid waste incineration called Ash2Salt, which enables recycling of salts; sodium chloride, potassium chloride, calcium chloride and ammonium sulphate. To compare this new process with some of today’s fly ash treatment processes available for Swedish and European fly ash a life cycle assessment (LCA) was performed. READ MORE
