11. Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron
Sammanfattning : Compacted graphite iron (CGI) is rapidly becoming an attractive alternative material for engine components in the automotive industry, replacing lamellar graphite iron (LGI) in applications where high mechanical strength is desired. However, the gain in mechanical strength comes with a cost; thermal conductivity, process control and machining are three areas that are more challenging for CGI. LÄS MER
12. MAX phase thin films : unique multifunctional ceramics with the elements Ti, Si, Ge, Sn, and C
Sammanfattning : Mn+1AXn phases are ternary carbides or nitrides (X) consisting of an early transition metal (M), and (A)- group element (group III-V). They combine ceramic and metallic properties with high oxidation and thermal shock resistance as well as low resistivity. LÄS MER
13. Use of Biorecognition Elements or Their Mimics in New Flow Analysis Systems
Sammanfattning : We have evaluated capacitive and thermal transducers for recognition of bio- molecular interactions with different analytes. These assays were made in flow analysis systems because of the simplicity such methods provide. LÄS MER
14. Influence of solid solutions on the properties of some apatite-type calcium salts relevant to the production of phosphate and silicate cements
Sammanfattning : The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. LÄS MER
15. Dynamic higher order equations for structural elements
Sammanfattning : The subject of this thesis is to derive and evaluate governing equations and corresponding boundary conditions for solid isotropic cylinders and isotropic micropolar rectangular plates. This is achieved by a systematic power series expansion approach, by either adopting a generalized Hamilton's principle or a direct approach. LÄS MER
