  2. 1. Numerical modeling of dielectrophoresis

    Author : Yuan Lin; Gustav Amberg; Olof Runborg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dielectrophoresis; orientation of rotation; fluid particle dynamics; microparticle; molecular dynamics; hydrodynamics; particle-particle interaction; superimposed; mobility; Fluid mechanics; Strömningsmekanik;

    Abstract : We investigate the dielectrophoretic separation of microparticles. Two different models are formulated in two characteristic time scales. The first model mainly accounts for the orientation behavior and rotational motion of non-spheric microparticles. The concept of effective charge is suggested to calculate the finite size non-spheric particles. READ MORE

  4. 2. Molecularly Imprinted Matrices for Electrochromatography

    Author : Leif Schweitz; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical technology and engineering; capillary electrophoresis; enantiomer; film coating; microparticle; continuous bed; monolith; molecular imprinting; capillary electrochromatography; Kemiteknik och kemisk teknologi; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis deals with the combination of electrochromatography and molecular imprinting technology. Electrochromatography is characterised by high separation efficiency, simple instrumentation, and minute consumption of sample. READ MORE

  5. 3. Exploring the ecotoxicity of microparticle debris

    Author : Zandra Gerdes; Elena Gorokhova; Martin Ogonowski; Tamara Galloway; Stockholms universitet; []
