16. Molten Salt Electrolytes for Calcium Batteries
Abstract : Batteries are in higher demand than ever before as well as increased requirements in terms of energy and power density. The desire for higher energy density has meant that electrolytes are pushed above their electrochemical stability limits and hence they decompose, but typically this is under control and a new beneficial phase is created at the electrode surface; the solid electrolyte interphase (SEI).

17. Early Hydration of Portland Cement
Abstract : The production of cement is responsible forapproximately 7 % of the total CO2 emissions caused by man. To compensate for high energyconsumption and CO2 emission, thus making the utilization of concrete more sustainable,several strategies can be used. READ MORE

18. Oxygen Storage Chemistry of Nanoceria
Abstract : The versatile redox chemistry of ceria (CeO2) originates from its Ce4f electron, which plays the key role in changing the oxidation state of Ce between +IV and +III. Ceria is, among other things, a material that can act as a powerful oxygen buffer with a high oxygen storage capacity (OSC). READ MORE

19. Direct conversion of methane-to-methanol: transition-metal dimer sites in small-pore zeolites: First-principles calculations and microkinetic modeling
Abstract : Direct conversion of methane to methanol is a highly desired reaction. Partially oxidizing methane into a liquid fuel at ambient temperature and pressure would enable utilization of natural gas and biogas to a much larger extent than what is possible today. READ MORE

20. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation
Abstract : This thesis presents the results of computer simulation studies of the structure, dynamics, and deformation of cross-linked polymer gels. Obtaining a fundamental understanding of the interrelation between the detailed structure and the properties of polymer gels is a challenge and a key issue towards designing materials for specific purposes.
