    Ceramic foams are prepared and coated with pre-ceramic polymers. These coating offers to tailor the surface properties like the wetting behavior in wide range by variation of the pyrolysis temperature. Due to the foams structure, they are useful for novel multi-phase mixing processes. This work shows the dependence of the phase dispersion of two immiscible liquid phases. This work shows the dependence of the phase dispersion of two immiscible liquid phases on the surface wettability of the foams.

    This work describes the use of the unusual silicon chemical vapor deposition precursor di-t-butoxydiacetoxysilane (DADBS), which allows the safe deposition of thin silica films in a controlled and reproducible manner at a lower thermal budget with a newly developed direct liquid injection – low pressure chemical vapor deposition system.

  3. Severe Plastic Deformation by Equal Channel Angular Pressing and Rolling: The Influence of the Deformation Path on Strain Distribution

    Rolling and equal channel angular pressing (ECAP), and the response offered by three materials were compared. The different strain paths of ECAP and rolling do not affect the strength, but rolling leads to smaller domain sizes and an accentuated texture, which induces elastic and plastic anisotropy. These processes operate at different strain rates; thus, in low stacking fault energy (SFE) materials, a more effective grain fragmentation by deformation- induced twins is observed after the ECAP process.

  4. Preparation of Ni-Encapsulated ZTA Particles as Precursors to Reinforce Iron-Based Composites

    Juanjian Ru, Yehua Jiang, Rong Zhou, Jing Feng, Yixin Hua and Qionglian Yang

    Ni-encapsulated ZTA particles as precursors to reinforce iron matrix composites are prepared by electroless deposition using a choline chloride-ethylene glycol (ChCl-EG) ionic liquid additive. The deposition sequence of the Ni coating layer is analyzed, and a schematic illustration is proposed. ChCl-EG plays the role of hindering the fast nucleation and crystal growth of Ni nuclei.

  5. Carbon Coated Alumina Nanofiber Membranes for Selective Ion Transport

    A novel type of ion-selective membranes based on alumina nanofibers with the diameter of ∼10 nm is proposed. A carbon layer deposited on the nanofibers by the CVD method provides electrical conductivity and ionic selectivity to the membranes. The potential applications of membranes include nano- and ultrafiltration of charged species. The nanofibrous structure with conductive carbon layer is perspective for realizing switchable ion-transport selectivity.
