high performance zif 8 molecular sieve membrane on hollow Ceramic Fiber via crystallizing rubbing seed deposition
Chemical Engineering Journal, 2013Co-Authors: Kai Tao, Chunlong Kong, Liang ChenAbstract:In this report, a continuous well-intergrown ZIF-8 membrane on hollow Ceramic Fiber tube was successfully synthesized by a novel crystallizing-rubbing seed deposition. It is shown that the obtained ZIF-8 membrane was compact and defect-free, with a thickness of about 5 lm. The obtained membrane displayed high H2 molecular sieve separation performance. Specifically, the H2 permeance reached an excellent value of 1.1 10 6 mol m 2 s 1 Pa 1, and the ideal separation factors for H2/CO2, H2/N2 and H2/CH4 were calculated to be 5.2, 7.3 and 6.8 at roomtemperature, respectively.We show that the fine seeds generated by crystallizing-rubbing play the key role for enhancing the heterogeneous nucleation of ZIF-8 crystals, which thus result in a high quality ZIF-8 membrane.

Improvement of thermal cycle characteristics of a planar-type solid oxide fuel cell by using Ceramic Fiber as sealing material
Journal of Power Sources, 2000Co-Authors: S Taniguchi, Mariko Kadowaki, Y. Miyake, Y. Akiyama, Tuchida Yasuo, Keishi NishioAbstract:The objective of this paper is to improve the endurance of solid oxide fuel cell (SOFC) against thermal cycles by reducing the stress caused by the difference in thermal expansion coefficients of alloy separator and electrolyte. The thermal cycle characteristics were improved by using a Ceramic Fiber for the sealing material. The Ceramic Fiber seemed to play the role of suppressing electrolyte-cracking by relaxing the stress set up during thermal cycles. The appropriate structure for the sealing material was investigated with 200 mm×150 mm×4 combined-cell single-layer modules. The glass was arranged around the internal manifold to suppress gas leakage, and the Ceramic Fiber was arranged around the electrolyte to prevent the glass from contacting the electrolyte. It was confirmed that the thermal cycle characteristics can be improved and that good cell performance can be maintained by adopting this gas seal structure.

strengths of Ceramic Fiber bundles theory and practice
Journal of the American Ceramic Society, 2017Co-Authors: Evan Benjamin Callaway, Frank W. ZokAbstract:The Weibull modulus and reference strength of Ceramic Fibers can be inferred from measurements of the tensile stress-strain response of a bundle of such Fibers. The goal of the present article is to address issues in the fidelity of results stemming from Fiber bundle tests and strategies to optimize outcomes. The issues are addressed through established theorems in uncertainty propagation, Monte Carlo simulations of Fiber bundle fracture, and experimental measurements on bundles of SiC Fibers of various length and surface condition. The study shows that optimal results are obtained when: (i) tests are performed on Fiber bundles with a gauge length that exceeds a critical value (specifically, that needed to prevent mechanical instabilities in the post-load-maximum domain); (ii) bundles are lubricated with a low-viscosity oil, to mitigate both inter-Fiber friction and dynamic coupling associated with release waves following Fiber fracture; and (iii) the Weibull parameters are obtained by directly fitting the measured stress-strain curves with the function predicted by Fiber bundle theory, rather than using methods based on either linear regression analysis of Weibull probability plots or fitting of the peak stress and strain alone.

mechanical behavior of a laminar Ceramic Fiber reinforced epoxy composite
Journal of the American Ceramic Society, 1992Co-Authors: Craig A. Folsom, Frank W. Zok, Fred F Lange, David B. MarshallAbstract:The mechanical properties of a noval laminar composite are investigated. The composite consists of dense alumina sheets bonded between sheets of a uniaxial carbon-Fiber-reinforced epoxy tape. The behavior of the composite in both flexural and tensile loading is characterized and the results are related to the properties of the constituents. The role of the interlaminar interface in composite behavior is also examined. Implications for the design of laminar composites with complex shapes are briefly discussed.
