1. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants
Sammanfattning : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. LÄS MER
2. Human copper ion transfer : from metal chaperone to target transporter domain
Sammanfattning : Many processes in living systems occur through transient interactions among proteins. Those interactions are often weak and are driven by small changes in free energy. LÄS MER
3. Classical and Car-Parrinello Molecular Dynamics Simulations of Polyvalent Metal Ions in Water
Sammanfattning : The aqueous solvation of metal ions is one of the long-standing and complex problems in chemistry, with implications for and applications in a broad range of biochemical and electrochemical systems, where water is the all-pervasive medium.This thesis describes computer simulations of Al3+(aq), Fe2+(aq), Fe3+(aq) and Cu2+(aq).

4. Transition metal dissolution from Li-ion battery cathodes
Sammanfattning : Lithium-ion batteries (LIBs) have become reliable electrochemical energy storage systems due to their relative high energy and power density, in comparison to alternative battery chemistries. The energy density of current LIBs is limited by the average operating voltage and capacity of oxide-based cathode materials containing a variety of transition metals (TM). LÄS MER
5. Characterizing ions in solution by NMR methods
Sammanfattning : NMR experiments performed under the effect of electric fields, either continuous or pulsed, can provide quantitative parameters related to ion association and ion transport in solution. Electrophoretic NMR (eNMR) is based on a diffusion pulse-sequence with electric fields applied in the form of pulses. LÄS MER
