1. Characterization of nano-scale materials for interconnect and thermal dissipation application in electronics packaging
Sammanfattning : This thesis focuses on studies of nano-scale materials in electronic packaging applications with respect to following aspects: surface analysis of nano-scale oxide of lead-free solder particles, and thermal performance and mechanical property studies of nano-scale fiber and metal composite-based thermal interface materials. The composition and thickness of the solder oxide have a direct impact on the quality of interconnects and the reliability of a packaged system. LÄS MER
2. Thermal Barrier Coatings : Durability Assessment and Life Prediction
Sammanfattning : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. LÄS MER
3. On modelling and simulation of perfused tissue during thermal treatment : thermal analysis of blood perfusion and lesioning during ablative neurosurgery
Sammanfattning : Thermal treatment means therapy for which heat is the therapeutic agent. During treatment, the tissue temperature is increased to an injurious temperature (higher than 43 °C for the most widely used treatments). The aim is to reach necrotic temperature in the treatment area and non-lethal temperature outside the same. LÄS MER
4. Functional Fibers for Biomedical and Thermal Management Applications
Sammanfattning : This thesis explores the integration of electrospun polymeric structures in two fields; fibrous scaffolds as cell culture substrates for biomedical applications and fiber carrier networks in metal matrix polymer composites as thermal interface materials in microsystems. Electrospinning has been found to carry great potential for a range of future biomedical engineering applications. LÄS MER
5. Thermal endometrial destruction by means of a balloon catheter : experimental and clinical evaluation of a new form of treatment for menorrhagia
Sammanfattning : Thermal endometrial destruction by means of a silicone balloon catheter is a new form of treatment for menorrhagia aimed at reducing menstrual blood loss. The purpose of the present work was to study, experimentally, the thermal effects on and the thermal conductivity of uterine tissue, to obtain a basis for the estimation of optimal treatment conditions by means of numerical analyses using a computer simulation model, to elucidate possible problems which may arise during the procedure, to evaluate how the patients tolerated this treatment and to judge which patients were suitable for this form of treatment and, finally, to study the uterine cavity after treatment and the long-term results of treatment.
