22. Modelling phosphorus dynamics in constructed wetlands upgraded with reactive filter media
Sammanfattning : Developing low-cost and effective technologies to upgrade phosphorus (P) removal from the catchment runoffs and rural wastewater treatment facilities is one of the main research agendas to save the Baltic Sea from eutrophication. In Sweden, the construction of the constructed wetlands has been one of the environmental objectives for wastewater quality improvement in the small communities. LÄS MER
23. Modelling and Experimental Investigation of the Dynamics in Polymer Electrolyte Fuel Cells
Sammanfattning : In polymer electrolyte fuel cells (PEFC) chemical energy, in for example hydrogen, is converted by an electrochemical process into electrical energy. The PEFC has a working temperature generally below 100 °C. Under these conditions water management and transport of oxygen to the cathode are the parameters limiting the performance of the PEFC.

24. Optimisation Challenges in Pressurised Hot Water Extraction of Polyphenols: Extraction and Degradation Kinetics
Sammanfattning : Pressurised hot water is an environmentally friendly alternative to hazardous organic solvents such as methanol and heptane. One of the many applications of using pressurised hot water extraction (PHWE) is to extract polyphenols from plants. The challenges in PHWE lies with the optimisation of extraction yield. LÄS MER
25. Multiscale modelling of total pressure effects on complete methane oxidation over Pd/Al2O3
Sammanfattning : The models used in heterogeneous catalysis are becoming more advanced and the literature shows an increased interest in incorporating the atomistic scale into microkinetics. Coupling kinetics based on first-principles calculations to macroscopic effects can pave the way towards more comprehensive modelling methods and to tailored catalyst designs. LÄS MER
