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
Sammanfattning : The forest industry is a large part of the Swedish economy and the export of pulp, paper and wood products constitutes 11% of the total Swedish export of goods. The main product of a pulp mill is purified cellulose, which has many great properties like biodegradability and non-toxicity. LÄS MER
Sammanfattning : This thesis explores the integration of functional electrospun micro- and nanofiber based materials in two fields of microsystem technology: fibrous scaffolds as cell culture substrates and fiber-reinforced metal matrix composites as thermal interface materials (TIMs).Electrospun structures have been found to carry great potential as biomimicking microenvironments for future tissue engineering and cell culture applications.

Sammanfattning : As the population gets older, the demands for new medical treatments increase since many of our most common diseases are related to age, including coronary heart disease, osteoarthritis and chronic ulcers. With this comes an increasing need for new biomaterial structures supporting and promoting tissue regeneration. LÄS MER
Sammanfattning : In this work, nanostructured biocomposite fibers and films with cellulose nanofibers (CNF), cellulose nanocrystals (CNC) and chitin nanocrystals (ChNC) were prepared using solutions mixing followed by electrospinning and melt compounding. The main processing challenges for these materials were to find parameters for: 1) fiber alignment in electrospinning, 2) feeding the nanomaterials into the extruder and 3) dispersion and distribution of the nanomaterials in the polymeric matrix.
