11. Removal of Metal Ions from Wood Chips during Acidic Leaching
Sammanfattning : Wood chips are the main source of intake of non-process elements at kraft pulp mills. It would be advantageous to decrease the content of these elements in the chips prior to pulping. LÄS MER
12. Modeling ionic liquids with ePC-SAFT ─ properties and gas solubilities
Sammanfattning : Global warming is now widely recognized as being the biggest global issue facing human beings. Mitigating CO2 emission from fossil-fueled power plants as well as from transports has become an urgent and worldwide research topic, in which CO2 separation is often needed. LÄS MER
13. Improving cellulose fibre properties by controlled adsorption of xylans
Sammanfattning : Hemicelluloses are, together with cellulose and pectins, the polysaccharide constituents in the cell walls of higher plants. Xylans are the most common hemicelluloses, and are considered to be the second most abundant biopolymer in the plant kingdom. LÄS MER
14. Carbon-graphite fiber-reinforced polymers for implant suprastructures
Sammanfattning : Carbon-graphite fiber-reinforced polymers (CGFR) can be used as the core material for implant-retained prostheses as an alternative to metal frameworks. The purpose was to formulate and develop carbon-graphite fiber-reinforced polymers intended for implant suprastructures and to determine physicochemical, mechanical properties and possible cytotoxic effects.

15. Additive-Driven Improvements in Interfacial Properties and Processing of TMP-Polymer Composites
Sammanfattning : Efforts to address environmental concerns have resulted in new regulations designed to plan the reduction of plastic and synthetic polymer usage, necessitating the search for sustainable natural alternatives with comparable cost-effectiveness and mechanical performance. Thermomechanical pulp (TMP) fibres are one of the most affordable natural fibres that have no chemical refining in production, production have a high yield of 90-98% and TMP fibres have been demonstrated to improve the mechanical characteristics (strength, stiffness and toughness) of wood-polymer composites (WPCs) compared to the pure polymer.
