  1. Synthesis of Carbon Nanotubes from Propane**

    Mariusz Zdrojek, Jan Sobieski, Anna Duzynska, Ewa Zbydniewska, Wlodek Strupinski, Jacek Ratajczak and Jarosław Judek

    Article first published online: 9 APR 2015 | DOI: 10.1002/cvde.201404329

    Growth of high quality CNTs using pure propane is demonstrated over a range of growth temperatures (600–1100 °C). SWCNT and MWCNT volumes in the grown material can by tuned using the growth temperature. The SEM image shows CNTs grown at 900 °C with both SWCNTs and MWCNTs visible. Increasing temperature yields higher depositions of disordered carbon material besides NTs.

  2. Effects of Synthesis Parameters on Silicon Nanopowders Produced by CO2 Laser-Driven Pyrolysis of Silane

    Junli Kong, Xuegeng Li, Pingrong Yu, Dong Wang, Sen Zhang and Ziqi Xu

    Apparatus for producing silicon nanoparticles by CO2 laser-driven pyrolysis of SiH4 is presented. Effects of process parameters on the average particle size, size distribution, and shape of the nanoparticles are systematically investigated. Produced silicon powders are much smaller and more uniform in size than commercial products and those previously reported. Impressive productivity and yield are also discussed.

  3. ITO-induced Columnar Polycrystalline Silicon Thin Films by CVD**

    Jun Du, Xin Gu, Huaqiang Fu, Haizhi Guo, Jiao Liu, Qi Wu and Jianguo Zou

    Article first published online: 12 MAR 2015 | DOI: 10.1002/cvde.201407138

    CVD is used to prepare ITO-induced polycrystalline silicon thin films with SiH4 as the precursor. The growth of columnar polycrystalline silicon is demonstrated. The sheet resistance of the films ranges from about 167.3 to 466.2 Ω/sq. Light absorption increases, as does the detected transmittance, by about 18.4% − 30.5% for wavelengths less than 500 − 700 nm.

  4. CFD Simulations of Hydrodynamics of Conical Spouted Bed Nuclear Fuel Coaters

    Senem Şentürk Lüle, Uner Colak, Murat Koksal and Gorkem Kulah

    Article first published online: 2 MAR 2015 | DOI: 10.1002/cvde.201407150

    CFD simulations of conical spouted beds operated with high density (6050 kg m−3) particles are performed using two fluid method (TFM). The modelling capability of the TFM approach is investigated by comparing simulation and experimental results. Contours of the solid volume fraction from CFD simulation (a) and a snapshot from experiment (b) show similar gas-solid flow pattern.

    Titanium Dioxide Thin Films Deposited by Electric Field-Assisted CVD: Effect on Antimicrobial and Photocatalytic Properties** (pages 63–70)

    Luz Romero, Clara Piccirillo, Paula M. L. Castro, Christopher Bowman, Michael E. A. Warwick and Russell Binions

    Article first published online: 7 JAN 2015 | DOI: 10.1002/cvde.201407145

    Thin films of titanium dioxide are deposited via electric field-assisted aerosol CVD. The application of electric fields in the deposition leads to the production of highly oriented thin films that are demonstrated to have significantly enhanced dye degradation and antibacterial properties when compared to a film deposited without the application of electric fields.
