1. A comparative study of natural illites from different origins
Sammanfattning : .... LÄS MER
2. Surface reactions of natural illites from different origins
Sammanfattning : Studies of natural illites from different origins were performed, including surface acid-base properties, determination of total inorganic carbonates, and spectroscopic investigations of chemical and structural nature as well as alterations of surface properties by acid-base titration. Using surface complexation model, the fitting results showed that the acid-base behavior of aqueous illite surfaces was dominated by deprotonation procedure. LÄS MER
3. Tracking environmental changes of the Baltic Sea coastal zone since mid-Holocene
Sammanfattning : In this thesis, I used two coastal sediment sequences from SE Sweden to study how Baltic Sea coastal environment has changed since the mid-Holocene. The results show the coastal environment has been influenced by multi-stressors, such as climate change, shoreline regression and anthropogenic activities. LÄS MER
4. The role of biogeophysical feedbacks and their impacts in the arctic and boreal climate system
Sammanfattning : The physical environment in the northern high latitudes including the Arctic cryosphere has undergone dramatic changes due to anthropogenic greenhouse gas warming, which since pre-industrial times has been twice or more the rate of global mean warming. Global climate models predict that this accelerated warming will continue for at least the next few decades. LÄS MER
5. Injectable Composite Hydrogels Based on Metal-Ligand Assembly for Biomedical Applications
Sammanfattning : This thesis presents new strategies to construct injectable hydrogels and their various biomedical applications, such as 3D printing, regenerative medicine and drug delivery. These hydrogels cross-linked by dynamic metal-ligand coordination bonds exhibit shear-thinning and self-healing properties, resulting in the unlimited time window for injection. LÄS MER
