In this paper, highly porous Si3N4 ceramics with high strength, homogeneous microstructure were fabricated by introducing a proper amount of nanometer carbon in the Si3N4 slurry by gel-casting. Scanning electron microscopy, X-ray diffraction, Archimedes water-displacement method and three-point bending tests were employed to analyze the microstructures and mechanical properties of the sintered bodies. It was shown by the XRD analysis that SiC particles were formed in the sintered bodies. The pillar β- Si3N4 morphology, homogeneous microstructure and the SiC particles as a reinforcement phase are the contributing factors for high porosity and good mechanical behavior.

A facile and novel method was developed to fabricate highly porous CeO2 surface on aluminum via a combination of homogeneous precipitation method and in situ growth process. After the introduction of CeO2 film, aluminum exhibited excellent superhydrophobicity with contact angle of 152.9±1.5 o and a sliding angle of 5 o. SEM image of the film showed that the resulting surface exhibits a hierarchical micro-Superscript text and nanostructure, which comprised of nanoleaves that grew perpendicular to the substrate and interleaved together to form a highly porous structure. This porous architecture, along with the low surface energy renders the aluminum superhydrophobicity.
