6. Atomic scale modeling of ordering phenomena
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 a computationally efficient exploration of the relevant configuration space. LÄS MER
7. Symmetry Breaking Ordering Constraints
Sammanfattning : Many problems in business, industry, and academia can be modelled as constraint programs consisting of matrices of decision variables. Such “matrix models” often have symmetry. In particular, they often have row and column symmetry as the rows and columns can freely be permuted without affecting the satisfiability of assignments. LÄS MER
8. Ordering in Crystalline Short-Chain Polymer Electrolytes
Sammanfattning : Polymer electrolytes are the most obvious candidates for safe "all-solid" Li-ion batteries and other electrochemical devices. However, they still have relatively poor ionic conductivities, which limits their wider adoption in commercial applications. LÄS MER
9. 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
10. Microstructure of Nickel-Chromium Superalloys
Sammanfattning : The microstructure of nickel-chromium superalloys has been investigated using several advanced microanalytical techniques; atom probe field ion microscopy (APFIM), transmission electron microscopy (TEM) together with energy dispersive X-ray analysis (EDX) and electron energy loss spectroscopy (EELS), secondary ion mass spectroscopy (SIMS) and optical microscopy (OM). The features primarily considered include precipitation, segregation and ordering. LÄS MER
