1. Multifunctional Carbon Foams by Emulsion Templating : Synthesis, Microstructure, and 3D Li-ion Microbatteries
Sammanfattning : Carbon foams are among the existing electrode designs proposed for use in 3D Li-ion microbatteries. For such electrodes to find applications in practical microbatteries, however, their void sizes, specific surface areas and pore volumes need be optimized. LÄS MER
2. The Complex Nature of the Electrode/Electrolyte Interfaces in Li-ion Batteries : Towards Understanding the Role of Electrolytes and Additives Using Photoelectron Spectroscopy
Sammanfattning : The stability of electrode/electrolyte interfaces in Li-ion batteries is crucial to the performance, lifetime and safety of the entire battery system. In this work, interface processes have been studied in LiFePO4/graphite Li-ion battery cells. LÄS MER
3. A Darwinian Theory of International Conflict
Sammanfattning : This dissertation aims to advance the current understanding of the general conditions affecting the likelihood of military conflicts and wars between states. To that end, the dissertation develops a Darwinian theory of international conflict. LÄS MER
4. Molecular perspectives on goethite dissolution in the presence of oxalate and desferrioxamine-B
Sammanfattning : Iron, an essential nutrient, is primarily present in soils in the form of iron-bearing minerals characterized with low solubilities. Under iron deficient conditions, some plants and microorganisms exude a mixture of iron-complexing agents, including carboxylates and siderophores, that can cause minerals to dissolve and increase iron solubility.
