1. Liquid phase sintering of W-Ni-Fe composites : liquid penetration, agglomerate separation and tungsten particle growth
Sammanfattning : The initial stage of liquid phase sintering, involving liquid penetration, agglomerate separation, particle spreading and growth has been investigated in experiments using tungsten heavy alloys. The particle composites used were produced by hot isostatic pressing (HIP) of pure powder mixtures of W-Ni-Fe-(Co). LÄS MER
Sammanfattning : Particle separation is one of the fundamental processes in wastewater treatment and a good understanding of the basic separation mechanisms ? sedimentation, flotation and filtration ? is critical in the design of wastewater treatment systems. Upgrading of treatment plants for enhanced primary treatment and effluent polishing are current examples of applications where effective, high-rate separation methods are of interest. LÄS MER
Sammanfattning : In a modern kraft pulp mill only about 45 % of the incoming wood is present in the pulp and it is mainly composed of cellulose. The remainder of the wood, which is dissolved in order to liberate the cellulose fibres, e.g., hemicellulose and lignin, ends up in the mill´s recovery boiler to recover the latent energy. LÄS MER
Sammanfattning : Dissolved Air Flotation (DAF) is a separation process in water and wastewater treatment. The removal function is based on reducing the density of the particle by producing aggregates of the particles and added micro-bubbles of air, thus lifting the aggregates to the water surface, where they can be removed as sludge.

Sammanfattning : The rise of MEMS and µTAS techniques has created a whole new family of microfluidic devices for a wide range of chemical and biomedical analyses to be performed on small Lab-on-a-chip platforms. The operations often include small samples of particle or cell suspensions on which separation, mixing, trapping or sorting is performed. LÄS MER
