1. Detection of nitrous oxide through IR-DFWM in gas flows with future application in ammonia flames
University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenAbstract : This thesis report on an investigation into the applicability of mid-infrared degenerate four-wave mixing (IR-DWFM) as a method to detect N\(_2\)O in ammonia flames. DFWM has previously been used for concentration measurements on other molecules, but has never, to the author's knowledge, been applied to measure N\(_2\)O in ammonia flames before. READ MORE

2. Transient Flow Simulations in Exhaust After Treatment Systems
University essay from Linköpings universitet/Mekanisk värmeteori och strömningsläraAbstract : The exhaust after treatment system is responsible for removing particulates and contaminants from the exhaust gases. The flow entering the SCR, a catalyst utilizing ammonia to reduce NOx emissions, was studied. The quality and distribution of flow entering the SCR plays an important role in the efficiency of the systems. READ MORE

3. Novel Ammonia Storage Materials for SCR Systems : Carbon Materials – Salt Composites
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : The emissions of nitrogen oxides (NOx) are a serious environmental problem due to its relationship with the formation of smog, acid rain and because they are dangerous for human and animal health. These gases are produced in high quantities in diesel engines used for automotive applications, and different strategies are being used to reduce them, among which are the Selective Catalytic Reduction (SCR) systems.

4. Graphene-based Coatings for Heat Exchangers
University essay from Lunds universitet/Centrum för analys och syntesAbstract : This master thesis is a part of a larger interwork between SP, KTH and Alfa Laval funded by the SIO graphene programme, which end goal is to formulate an anti-corrosion coating based on graphene or graphene related materials (GRMs). The investigation is partly based on an article “Novel anticorrosion coatings prepared from polyaniline/graphene composites” from 2012 by Chang et al in combination of knowledge acquired during a previous EU project, www.

5. An Interdisciplinary Study on Farm Based Biogas Production in Southern Brazil
University essay from Sektionen för ekonomi och teknik (SET)Abstract : Today the use of anaerobic digestion technique emerges as an alternative to the conventional treatment method of pig slurry to the pig producers in Brazil because of the energy demanding intensive pig production and the negative environmental impact that arises during storage and use. The end products of AD technique are biogas as an energy source and digestate that can be used as a fertilizer. READ MORE
