  4. 23. Numerical modeling of dielectrophoresis

    Författare :Yuan Lin; Gustav Amberg; Olof Runborg; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 25. Role of respiratory supercomplexes : Electronic connection between complexes III and IV

    Författare :Agnes Moe; Peter Brzezinski; James A. Letts; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electron transfer; cytochrome c oxidase; cytochrome bc1; respiratory supercomplex; bioenergetics; membrane protein; biokemi; Biochemistry;

    Sammanfattning : In the final step of cellular respiration, electrons are transferred through the respiratory chain to reduce molecular oxygen to water. The energy released in this chain is used to maintain a proton electrochemical gradient across the cell membrane, which is used, for example, by the ATP synthase to produce ATP. LÄS MER
