  1. 11. Acoustic separation and electrostatic sampling of submicron particles suspended in air

    Författare :Ramin Imani Jajarmi; Etienne Robert; Lisa Prahl Wittberg; Laszlo Fuchs; Martin Wiklund; Klas Engvall; Jeremy Hawkes; Michel Cervantes; Mats Åbom; Olga Roditcheva; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic; separation; acoustophoresis; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : We investigate experimentally the effects of acoustic forces on submicron aerosol in a channel flow. This technique can potentially overcome some of the limitations of conventional separation systems and provide advanced manipulation capabilities such as sorting according to size or density.

  3. 12. Wet Low-Intensity Magnetic Separation: Measurement methods and Modelling

    Författare :Jan Stener; Holger Lieberwirth; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : In the mining industry, ferromagnetic particles (e.g. magnetite) are concentrated using wet low-intensity magnetic separation (LIMS). Mineral particles in suspension with water are pumped into the separator tank, and a magnetic concentrate is extracted by use of magnetic forces. LÄS MER

  4. 13. Deterministic Lateral Displacement for Cell Separation

    Författare :Si Hoai Trung Tran; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deterministic lateral displacement; Cell Separation; Open microfluidics;

    Sammanfattning : In the fields of medicine and biology, the separation of particles is a central step in many preparative and analytical processes. Deterministic Lateral Displacement (DLD) has been a promising technique in the field of microfluidic particle and cell sorting, specifically for label-free separation with several applications of sorting by size, morphology, and deformation reported in the literature over the last decade.

  5. 14. Particle-Induced Phase Separation in Aqueous Solutions containing Colloidal Particles and Adsorbing Polymers

    Författare :Martin Olsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; biopolymers; Polymerteknik; theoretical calculations; particle-induced phase separation; phase behaviour; surfactant; colloidal particles; adsorbing polymer;

    Sammanfattning : The influence of added colloidal particles on the phase behaviour of a polymer solution was investigated. Binary, quasi-binary and mixed polymer solutions were used in the study, where at least one of the polymers had an affinity for the surfaces of the colloidal particles. LÄS MER

  7. 15. Microfluidics Separation and Analysis of Biological Particles

    Författare :Jason Beech; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Point-of-care; Lab-on-a-chip; Microfluidics; Separation science; Deterministic Lateral Displacement; morphology; deformability; Fysicumarkivet A:2011:Beech;

    Sammanfattning : In the last decade, powerful communication and information technology in the form of the mobile phone has been put into the hands of more than 50% of the global population. In stark contrast, a lack of access to medical diagnostic technology with which to diagnose both communicable and non-communicable diseases will mean that many of these people will die of easily treatable conditions.
