讲学题目1：Ceramic Integration Technologies for Energy and Environmental Applications: Technical Challenges and Opportunities
讲学时间：2009年7月2日9:00~10：00
讲学地点：邵馆2楼报告厅
讲学内容摘要：
Advanced ceramic integration technologies dramatically impact the energy and environment landscape due to wide scale application of ceramics in all aspects of alternative energy production, storage, distribution, conservation, and efficiency. Examples include fuel cells, thermoelectrics, photovoltaics, gas turbine propulsion systems, distribution and transmission systems based on superconductors, nuclear power generation, nuclear waste disposal, NOx and COx reduction technologies, and a wide variety of green manufacturing processes and technologies. Various ceramic integration technologies play a role in fabrication and manufacturing of large and complex shaped parts of various functionalities. However, the development of robust and reliable integrated systems with optimum performance requires the understanding of many thermochemical and thermomechanical factors, particularly for high temperature applications.
In this presentation, various challenges and opportunities in design, fabrication, and testing of integrated similar (ceramic-ceramic) and dissimilar (ceramic-metal) material systems will be discussed. Experimental results for bonding and integration of SiC based Micro-Electro-Mechanical-Systems (MEMS) LDI fuel injector, high conductivity C/C composite based thermal management system, solid oxide fuel cells system, and advanced ceramics and composites for turbine applications will be presented. Potential opportunities and need for the development of innovative design philosophies, approaches, and integrated system testing under simulated application conditions will also be discussed.
讲学题目2：New Biomorphic Ceramic Materials for Biomedical Applications
讲学时间：2009年7月2日10：30~11：30
讲学地点：邵馆2楼报告厅
讲学内容摘要：
During the recent years, there has been a great deal of interest and attention in the development of advance biomedical implant technologies and lightweight implant materials with enhanced mechanical properties, durability, and biological response. The remarkable biomechanical properties of tissues to be substituted or repaired, depends on their hierarchical structure which is an organized assembly of structural units at increasing size levels. Bimorphic silicon carbide ceramics, fabricated from bio-derived cellulose templates, are lightweight, tough and high-strength materials with interesting biocompatibility with natural tissues. These biomorphic ceramics mimic the natural structure of bone. Utilizing the innovative processing approaches and the outstanding mechanical properties of the starting templates, it is possible to develop scaffolds for bone substitution with a suitable structure-morphology to reach improved biomechanical performance. In this presentation, microstructure, chemical composition, and mechanical properties of different types of biomorphic silicon carbide ceramics will be presented along with the in vitro biocompatibility test data. The versatility of the system opens the door to a whole new generation of implants for biomedical applications.
