6. The synthesis, surface modification and use of metal-oxide nanoparticles in polyethylene for ultra-low transmission-loss HVDC cable insulation materials
Sammanfattning : Polyethylene composites which contain low concentrations of metal-oxide nanoparticles e.g. ZnO and MgO are emerging materials for the use in insulations of extruded high-voltage direct-current (HVDC) cables. LÄS MER
7. Surface reactions on metallic nanoparticles : Ligand adsorption, metal release, and reactive oxygen species generation
Sammanfattning : Humans are exposed daily to metallic nanoparticles (Me NPs) from multiple sources which can have both natural and anthropogenic origins. Such exposures take place via different routes including inhalation and skin contact and may result in adverse health effects. LÄS MER
8. Potential of Organosolv Lignin Nanoparticles as a Sustainable Flotation Reagent : Towards a Low-Carbon Footprint Mining Industry
Sammanfattning : The green transition is driving a steep increase in the demand for minerals, which has put the focus on more responsible and sustainable mining practices as there is a growing pressure on mining operations to minimise their environmental footprint, mitigate risks in neighbouring communities, and decrease the consumption of natural resources. In 2022, mineral froth flotation was used to recover 18 million tonnes of copper from copper ore, accounting for 80% of total copper mine output. LÄS MER
9. Biosynthesis, interactions, and structure of native lignin
Sammanfattning : Wood biomass is an important resource in the development ofstrategies towards replacement of fossil-based materials. Woodcomprises cellulose, hemicelluloses and lignin, in amounts thatvary between species. LÄS MER
10. Experimental and numerical investigations of hydrodynamic focusing of colloidal dispersions
Sammanfattning : Dispersed non-spherical particles are the fundamental constituent of many complex fluids. Such fluids are studied both for their industrial and scientific importance, and for their peculiar functional properties (mechanical, optical, thermal, fluidic). LÄS MER
