2. Synthesis–Structure–Property Relationships in Li- and Mn-rich Layered Oxides
Sammanfattning : The commercialisation of Li-ion batteries over the last decade has provided additional impetus for the improvement of existing energy storage technologies. Towards this, a major portion of the global efforts includes exploratory research aimed at the development of new material chemistries. LÄS MER
3. Investigating ageing mechanisms in electric vehicle batteries : A multiscale approach to material analysis
Sammanfattning : Electrifying passenger transport is a key strategy in combating global warming, with Li-ion batteries (LIBs) being the current go-to technology. Despite LIB’s satisfactory performance and carbon-neutral operation, lifetime and safety are still public concerns. LÄS MER
4. Harnessing Mesoporous Spheres - transport studies and biotechnological applications
Sammanfattning : Applications in controlled release and delivery calls for a good understanding of molecular transport within the carrier material and the dominating release mechanisms. It is clear that a better understanding of hindered transport and diffusion of guest molecules is important when developing new porous materials, e.g. LÄS MER
5. Aromatic Polymers Functionalized with Anionic and Cationic Groups for Ion Exchange Membranes
Sammanfattning : Fuel cells, redox flow batteries and some water desalination technologies such as reverse osmosis and electrodialysis require efficient ion exchange membranes to perform in an optimum way. Thus, by enhancing the properties of these membranes there is a possibility to improve this type of applications and technologies. LÄS MER
