  2. 1. Particle dynamics during biomass devolatilization : Momentum exchange and particle dispersion

    Author : Angel David Garcia Llamas; Kentaro Umeki; Rikard Gebart; Per Gren; Peter Glarborg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; devolatilization; rocketing; PIV; PTV; Energiteknik; Energy Engineering;

    Abstract : Devolatilization is a heat-driven thermochemical process in which a liquid or a solid fuel releases mass in the form of volatile compounds after drying, as a result of the combination of endothermic and exothermic reactions. It differs from pyrolysis in that it does not require an inert atmosphere and that the reactant must be either solid or liquid. READ MORE

  4. 2. Bridging Single-Particle Characterisation Gaps of Optical Microscopy in the Nano-Submicron Regime

    Author : Erik Olsén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; holography; particle shape; dynamics; Optical microscopy; particle tracking; size estimation; iSCAT; material sensitivity;

    Abstract : As the practical importance of particles in the nano-submicron size regime continues to increase in both biomedical applications and industrial processes, so does the need for accurate and versatile characterisation methods. Optical scattering microscopy methods are commonly used for single-particle characterisation as they provide quick measurements at physiologically relevant conditions with detection limits reaching down to individual biomolecules.

  5. 3. Estimating Effective Interactions from Particle Trajectories

    Author : Kolbjörn Tunström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mori-Zwanzig projection; Force matching; United atoms; Multi-scale molecular dynamics; Coarse-graining; Molecular dynamics thermostat; Inverse Monte Carlo; Dissipative particle dynamics; Swarming;

    Abstract : The theoretical and practical understanding of molecular systems is strongly dependent on computer simulations. All-atom molecular dynamics techniques are capable of sim- ulating systems on the scale of millions of particles up to about 100 ns. READ MORE

  6. 4. Protein structure dynamics and interplay : by single-particle electron microscopy

    Author : Hans Elmlund; Hans Hebert; José Maria Carazo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biophysics; biochemistry; molecular; Biophysical chemistry; Biofysikalisk kemi;

    Abstract : Single-particle cryo-electron microscopy (cryo-EM) is a method capable of obtaining information about the structural organization and dynamics of large macromolecular assemblies. In the late nineties, the method was suggested to have the potential of generating “atomic resolution” reconstructions of particles above a certain mass. READ MORE

  7. 5. Eulerian-Lagrangian modeling of particle motion in exhaust gas aftertreatment systems

    Author : Henrik Ström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urea-SCR; particle trapping; flow-through filter; urea decomposition; diesel particulate matter; particle motion; particle filter; AdBlue-spray; Eulerian-Lagrangian modeling;

    Abstract : In the work to design and optimize new aftertreatment system devices for NOx reduction and particulate matter removal in lean engine exhaust (such as diesel exhaust), it is of great help to be able to perform quick, robust and reliable computer simulations of system performance. A suitable platform for such simulations is Computational Fluid Dynamics (CFD) software. READ MORE
