1. Urea Decomposition for Urea-SCR Applications
Sammanfattning : Volatile emissions produced by the combustion of fossil fuels may be converted on a catalyst to less harmful products. During lean combustion an excess of oxygen in the exhaust gases together with a catalyst effectively oxidizes carbon monoxide and hydrocarbons into carbon dioxide and water. LÄS MER
2. On the mechanism of Urea-induced protein denaturation
Sammanfattning : It is well known that folded proteins in water are destabilized by the addition of urea. When a protein loses its ability to perform its biological activity due to a change in its structure, it is said to denaturate. LÄS MER
3. Urea and Non-Protein Nitrogen Metabolism in Infants : With Special Reference to the Sudden Infant Death Syndrome (SIDS)
Sammanfattning : A large amount of non-protein nitrogen, in the form of urea and ammonium, is present in human breastmilk; however its physiological role in the infant is as yet not fully understood. It has been hypothesized that an insufficient enteric metabolism of urea could play a role in the sudden infant death syndrome (SIDS). LÄS MER
4. Computational Fluid Dynamics and Experimental Studies of the Urea-SCR System
Sammanfattning : Volatile emissions produced by the burning of fossil fuels may be converted on a catalyst to less harmful products. During lean combustion an excess of oxygen in the exhaust gases together with a catalyst effectively oxidizes carbon monoxide and hydrocarbons into carbon dioxide and water. LÄS MER
5. Corrosion of Stainless Steel in Diesel Exhaust Gas After-treatment Systems with Urea Injection
Sammanfattning : The demands on lowering the emissions from fossil fuel keep increasing. Together with higher demands of longer component lifetime and lighter vehicles for lower fuel consumption this has led to an increasing use of stainless steels in exhaust after-treatment systems. LÄS MER
