Soils and groundwater are often contaminated by complex organic mixtures also called Non Aqueous Phase Liquids (NAPLs). Several techniques such as drilling, monitoring of soil gas or injection tracers traditionally used to quantify NAPLs in aquifers but perform. The use natural 222Rn could be an easy cheap alternative. This method requires the knowledge radon NAPL-water partitioning coefficient...

conflagration of forests and rangelands is one of the most frequent events in iran. it is regarded as one of the most important parts of land degradation that occurred due to range destruction and desertification. this study was conducted in boroujerd, lorestan province in west of iran in 2013 to determine the fire risk model. the data prepared for the study area involved the vegetation types, ...

2-Propanol/acetone is a promising LOHC (Liquid Organic Hydrogen Carrier) system for fuel cell reactions. In this paper six different concepts 2-propanol/acetone are evaluated in Matlab simulation with respect to their thermodynamic integration and technical feasibility. Four of the use direct 2-propanol while other two first release molecular hydrogen from subsequently cell. The presented liqui...

Solid oxide fuel cells are high temperature electrochemical devices for direct conversion of fuel and oxidant to electricity and heat. The high temperature and dual atmosphere creates challenges for the materials in solid oxide fuel cell stacks. In this thesis SOFC stack materials were studied and developed. SOFC stacks are assembled at room temperature, then heated up, conditioned and operated...
