1. Covalent Graphene Functionalization for the Modification of Its Physical Properties
Sammanfattning : Graphene, a two dimensional monolayer carbon sheet with the atoms tightly packed in a hexagonal lattice, has exhibited so many excellent properties, which enable graphene to break several material records with regard to carrier mobility, strength yield and thermal conductivity to name a few. Therefore, graphene has been placed as a potential candidate to allow truly next-generation material. LÄS MER
2. Surface Modification of Cellulose by Covalent Grafting and Physical Adsorption
Sammanfattning : The interest in new environmentally friendly cellulose‐based productshas increased tremendously over the last years. At the same time theSwedish forest industry faces new challenges in its strive to increase the utilization of cellulose fibers in high‐value end‐products. LÄS MER
3. On Particle Transport and Turbulence Modification in Air-Particle Flows
Sammanfattning : The transport of particles by airflow was studied for two different flow cases, the transport of pulp fibres in a mat-forming process and the transport of pulp fibres and spherical particles in a horizontal pipe. The transport of pulp fibres in the mat-forming process is first considered. LÄS MER
4. Surface modification of III-V nanostructures studied by low-temperature scanning tunneling microscopy
Sammanfattning : In the past decade, driven by the demand for materials with high performance for next-generation semiconductor devices (e.g. LÄS MER
5. The dynamic surface nature of calcite and its role in determining the adsorptive stability toward hydrophobizing carboxylic fatty acids
Sammanfattning : Calcium carbonate has attracted a lot of interest over the centuries. Nowadays, mainly as mineral pigment and filler, it has a wide use in technological applications ranging from paper, construction, polymers, and environmental solutions to consumer goods. LÄS MER
