1. Semiconductor Hetero- and Nanostructures
Sammanfattning : In this thesis, chemical beam epitaxy was used to fabricate nm-sized crystalline structures. Most of the systems were based on heterostructures, i.e., combinations of different kinds of crystalline materials. LÄS MER
2. Metal and Semiconductor Nanocrystals for Quantum Devices
Sammanfattning : Aerosol technology was used to develop new methods for fabrication of size-selected, nanometer-sized particles of metals and semiconductors. Such particles were used to realize different types of quantum devices and nanometer-sized structures. LÄS MER
3. Nanostructured materials isolated from bio-residues, and their characterization
Sammanfattning : The use of natural components in nanocomposites has continuously increased, due to environmental problems that are growing day by day. The use of bio-residues from forest industries to develop new materials will not only alleviate ecological problems but also affect the economy of forest industries positively. LÄS MER
4. Dried nanofibrillated cellulose and its bionanocomposites
Sammanfattning : During the past decade there has been a growing interest in the reinforcement of synthetic polymers with cellulose nanowhiskers and nanofibrillated cellulose (NFC) obtained from plants or bacteria. Their beneficial mechanical properties like high stiffness and strength, in combination with their low mass allowed successful reinforcement of water based polymer dispersions (latexes) for the production of solution cast composite films.
