Ceramic Materials for Mass-Sensitive Sensors - Detection of VOCs and Monitoring Oil Degradation
Advances in Science and Technology, 2006Inorganic frameworks obtained by the sol-gel route can be templated by a molecular imprinting (MIP) approach to generate functional cavities. Such MIP ceramics show highly appreaciable properties for chemical sensor applications, because they are inherently chemically and thermally robust. In combination with mass-sensitive devices (e.g. quartz crystal

Ceramic matrix composite materials for thermal protection systems are required to maintain operational performance in extreme thermal and mechanical environments. In‐service inspection of materials capable of assessing the degree and extent of damage and degradation will be required to ensure the safety and readiness of future air vehicles.

Composites and Functionally Graded Materials, 1997
Abstract A physically-based damage model has been developed to predict the nonlinear behavior of cross-ply ceramic matrix laminates due to progressive failures. It has been shown to model the nonlinear stress-strain response of chemical vapor infiltrated (CVI) SiC/SiC composites under tension loading accurately.

Effect of TiN Addition on the Low Temperature Degradation of Ceramic Tool Materials 3Y-TZP
Key Engineering Materials, 2006Ceramic tool materials, 3Y-TZP added by TiN particles, were fabricated through hot-pressing techniques. The effects of TiN on their low-temperature degradation at 220# in air were investigated. It is shown that TiN can improve the stability of t-ZrO2 and inhibit the transformation from tetragonal to monoclinic phase, and that the content of TiN affects

Low-temperature degradation may affect zirconia restorations during their clinical service. Concerns have been raised about the effect of low-temperature degradation on the wear behavior of zirconia. Moreover, the wear resistance of this novel polymer-infiltrated ceramic-network material needs to be better evaluated.The purpose of this in vitro study ...

Zirconia-based bioceramics have been widely applied in the field of prosthodontics owing to its desirable mechanical performance, biocompatibility and aesthetics. However, the low-temperature degradation (LTD) of tetragonal zirconia (ZrO2) under intraoral condition can lead to the deterioration of mechanical properties of ZrO2 dental crowns, which ...

Abstract Improving the mechanical properties and maintaining the desired degradability of the bioceramic scaffold is always being a contradiction in the field of bone tissue engineering. To resolve this conflict, highly degradable mesoporous bioactive glass (MBG) was homogenously coated on the mechanically stronger hardystonite (Ca2ZnSi2O7, HT ...
