1. Experimental studies of ion transport in cementitious materials under partially saturated conditions
Abstract : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. READ MORE

2. Nanoconfined imidazolium ionic liquids
Abstract : Long-chain ionic liquids are attracting interest as alternatives to their short-chain analogues as electrolytes. At the same time, they are also considered as alternatives to mesogens and conventional surfactants as templates. READ MORE

3. Local Structure and Dynamics of Next Generation Electrolytes - linking microscopic and macroscopic properties
Abstract : The electrolyte is a crucial part of a battery in terms of performance, longevity and safety. However, the state-of-the-art electrolytes for lithium-ion batteries are based on organic solvents and Li-salts (typically at 1M concentration) which are volatile and degrade at higher temperatures.

4. Ionic Transport in Metal Oxides Studied in situ by Impedance Spectroscopy and Cyclic Voltammetry
Abstract : Ionic transport in metal oxides is crucial for the functioning of a broad range of different components, such as heat resistant alloys designed for high temperature applications and oxide electrolytes in solid oxide fuel cells. This thesis presents results from in situ electrochemical studies of properties related to ionic transport in metal oxides that are important for their applications as protective oxides and ionic conductors.

5. Transport of Radionuclides and Colloid Through Quartz Sand Columns
Abstract : Studies of the transport of radionuclides in the geosphere are one of the main tasks for performance assessment of a nuclear waste repository. A possible enhanced transport path for the radionuclides is the formation and transport of non-depositing colloids with a high affinity for radionuclides. READ MORE
