    1. The Influence of Pixel Numbers and Image Centring upon Particle Size Analysis Accuracy (pages 71–75)

      Maurice Wedd

      Using image analysis as a reference method for particle sizing with measurement errors of less than 1 % is quite challenging. For this purpose a pixel array has been modeled to examine the influence, upon image analysis measurement accuracy, of pixel number, threshold levels and image centring.

    2. Experimental Determination of Liquid Spray Drop Morphology Qualitative Information from Laser-Diffraction Measurements (pages 76–88)

      Christophe Dumouchel, Sébastien Grout, Bertrand Leroux and Xavier Paubel

      The Laser-Diffraction Technique applied to sprays is sensitive to the drop shape. Comparison to image analysis and application of the recently developed surfacescale distribution is performed. This way a relationship between the mean-diameter series and the mean-scale series is established. This indicates that information on the droplet shape is available in the mean-diameter series reported by the laser diffraction.

    3. Indirect Fourier Transform and Model Fitting of Small Angle Neutron Scattering from Silica Nanoparticles (pages 89–99)

      Nathan Hould, Raul Lobo and Norman Wagner

      Version of Record online: 24 AUG 2011 | DOI: 10.1002/ppsc.201000006

      Small angle neutron scattering (SANS) patterns were interpreted using model fitting and indirect Fourier transform methods. Furthermore, by modeling the effective structure factor particle interactions are determined. An indirect Fourier transform is found to be a more robust method to calculate the radial distribution function for interacting particles.

    4. Inception and Trapping of ZnO Nanoparticles within Desilicated Mordenite and ZSM-5 Zeolites (pages 100–111)

      Arturo Susarrey-Arce, Miguel Angel Hernández-Espinosa, Fernando Rojas-González, Christopher Reed, Vitalii Petranovskii and Angel Licea

      Version of Record online: 13 JUL 2011 | DOI: 10.1002/ppsc.201000027

      ZnO nanoparticle inception within mordenite and zeolites was achieved via ion exchange followed by NaOH leaching and thermal treatment. ZnO particles were characterized by high resolution electron microscopy; further characterization included X-ray diffraction, thermogravimetric analysis, and N2 sorption as well as ICP-AE spectrometry and XPS. The final zeolite products are endowed with a twofold micromesoporosity.

    5. A Colloidal Silica Reference Material for Nanoparticle Sizing by Means of Dynamic Light Scattering and Centrifugal Liquid Sedimentation (pages 112–124)

      Olivier Couteau, Jean Charoud-Got, Hubert Rauscher, Fabio Franchini, François Rossi, Vikram Kestens, Katrin Franks and Gert Roebben

      Version of Record online: 24 AUG 2011 | DOI: 10.1002/ppsc.200900094

      A new nanoparticle reference material (RM) consisting of silica nanoparticles suspended in an aqueous solution is presented. Particle size distribution, homogeneity and stability are characterized thoroughly. The differences obtained by dynamic light scattering and centrifugation are discussed in detail.
