    1. Second Harmonic Generation Spectroscopy as a Method for In Situ and Online Characterization of Particle Surface Properties (pages 351–359)

      Lars Schneider and Wolfgang Peukert

      Article first published online: 23 FEB 2007 | DOI: 10.1002/ppsc.200601084

      Non-linear optical spectroscopy is an emerging technique for the investigation of colloidal interfaces. It is a non-invasive method which can be applied in-situ with real time resolution. This paper gives an overview of the fundamentals of this technique and its possible applications.

    1. Modeling Focused Beam Reflectance Measurement and its Application to Sizing of Particles of Variable Shape (pages 360–373)

      Andrea Vaccaro, Ján Šefčík and Massimo Morbidelli

      Article first published online: 20 DEC 2006 | DOI: 10.1002/ppsc.200600977

      A model for particle detection using FBRM is presented in the general case of particles of arbitrary convex shape. Shape dependent convolution schemes between measured chord length distributions and particle size distribution or particle mass distribution, respectively, are derived. Specific issues related to non-spherical particles as well as the role of weighting characteristic are discussed in detail.

    2. Particle Size Distribution Retrieval from Elastic Light Scattering Measurements by a Modified Regularization Method (pages 374–380)

      María L. Arias and Gloria L. Frontini

      Article first published online: 20 DEC 2006 | DOI: 10.1002/ppsc.200601083

      Retrieval of particle size distributions from Elastic Light Scattering measurements requires the solution of an ill-posed problem. In this paper classical regularization methods are compared to a new method due to Pike including a positivity constraint. Furthermore, a new method combining Thikonov regularization with Pikes method is presented. The effect of different inversion techniques on obtained size distributions is discussed in detail.

    3. Size and Shape Analysis of Sedimentary Grains by Automated Dynamic Image Analysis (pages 381–387)

      Daisy Tysmans, Philippe Claeys, Luc Deriemaeker, Dominique Maes, Robert Finsy and Marc Van Molle

      Article first published online: 10 NOV 2006 | DOI: 10.1002/ppsc.200500965

      The application of Automated Dynamic Image Analysis for measuring the size and shape of a large ensemble of sedimentary grains in a size range of 10 to 1,500 μm is presented. Projected area and perimeter are transformed into size-independent shape values. Statistical and systematic errors are discussed and a test to identify similarities and differences between grains is presented.

    4. Simulation and Statistical Analysis of Random Packings of Ellipsoids (pages 388–398)

      Alexander Bezrukov and Dietrich Stoyan

      Article first published online: 20 DEC 2006 | DOI: 10.1002/ppsc.200600974

      An algorithm for the generation of random packings of ellipsoids is presented. Resulting packings are characterized by their densities, pair-correlation and orientation-correlation functions. Furthermore a phase diagram in analogy to statistical physics is successfully applied.

    5. Measurement of Cake Strength in Potash Using a Centrifuge (pages 399–407)

      Yan Wang, Robert W. Besant, Richard W. Evitts and Allan T. Dolovich

      Article first published online: 10 NOV 2006 | DOI: 10.1002/ppsc.200601040

      A method for measuring the area- avareged tensile cake strength using a ring centrifuge is presented. This procedure is then applied to measure cake strength for a series of samples with potash fertilizer for varying initial moisture contents and drying kinetics.

    6. The Simulation of Electrostatic Spray Painting Process with High-Speed Rotary Bell Atomizers. Part II: External Charging (pages 408–416)

      Joachim Domnick, Andreas Scheibe and Qiaoyan Ye

      Article first published online: 10 NOV 2006 | DOI: 10.1002/ppsc.200601018

      A complete model for the simulation of electrostatically assisted spray painting is presented, including simulation of corona discharge, electric field, ion transport, flow field as well as particle charging and transport. Comparison of numerical and experimental results show good agreement, especially for integrating parameters, like resulting film thickness distribution on the target.
