1. Improving Thermoelectric Properties of Inorganic Clathrates by Atomic and Microscale Structure Engineering
Sammanfattning : As more countries are aiming for a carbon-neutral economy, technologies that utilize renewable energies are increasingly being considered. Thermoelectric materials enable the direct conversion between a thermal gradient and an electrical potential gradient, and are thus exploited for applications such as waste heat recovery. LÄS MER
2. Synthesis and Characterization of New Inorganic Thermoelectric Materials
Sammanfattning : With thermoelectric materials it is possible to convert a difference in temperature into electrical energy. This can be utilized for a more efficient use of available energy, eg. by converting waste heat from a combustion process. LÄS MER
3. Unlocking the potential of a caged star: Thermoelectric quaternary clathrates
Sammanfattning : Heat losses are an inevitable consequence of any energy conversion process, dictated by the second law of thermodynamics. This not only leads to an eternal struggle, via the pursuit of maximal efficiency, it also undermines our efforts to solve the two issues that pose the most significant challenges to modern society: climate change and the worlds surging energy need.

4. Structure and Thermoelectric Properties of Type-I Clathrates Ba8(AlxGa1−x)16Ge30
Sammanfattning : Thermoelectric materials enable the direct conversion between a thermal gradient and an electrical potential gradient, and can thus be exploited for electricity generation. One of the promising thermoelectric materials is type-I clathrates. LÄS MER
5. Atomic scale modeling of ordering phenomena in inorganic clathrates
Sammanfattning : Ordering phenomena in materials often have a crucial impact on materials properties. They are governed by the competition between entropy and energy. Accordingly simulating these aspects requires the construction of models that enable an computationally efficient exploration of the relevant configuration space. LÄS MER
