Title: Materials selection for the next generation thermal barrier coatings
Abstract: One of the major successes of engineered ceramics has been the development of the thermal protection system for high-temperature gas turbines. For the last twenty-five years, the ceramic material of choice as a thermal barrier coating has, and continues to be, yttria-stabilized zirconia containing 8 weight percent yttria (8YSZ). As the development of more efficient gas turbines proceeds there is a need for an oxide coating that can sustain higher operating temperatures than 8YSZ. However, no existing oxide has the required combination of low thermal conductivity, adequate fracture toughness, low optical absorption in the infra-red and high temperature stability as well as compatibility with alumina that forms on superalloys at high temperatures. In this presentation, I will discuss the design requirements for the next generation gas turbines as well as a number of approaches being taken to identify suitable oxide systems. As part of the presentation, I will also describe our recent work on the basis for selecting oxides with exceptionally low thermal conductivity at high temperatures as well as studies of the YTaO4-ZrO2 system which we believe has particular promise for future coatings.

Bridge Building Award
Sanjay Mathur, chair, Institute of Inorganic Chemistry, University of Cologne, Germany
Title: Chemically processed nanostructured ceramics: Opportunities for energy and health applications
Abstract: Chemical nanotechnologies play a key role in converging physical and life sciences and engineering ceramics. Chemical processing enables facile and efficient synthesis and assembly of nanocrystals of precisely defined chemical compositions that can be engineered for energy and health applications. Metal oxide nanostructures inherit promises for substantial improvements in materials engineering mainly due to improved physical and mechanical properties resulting from the reduction of microstructural features by two to three orders of magnitude, when compared to current engineering materials. This talk will present how chemically grown nanoparticles, nanowires and nanocomposites of different metal oxides open up new vistas of material properties, which can be transformed into advanced material technologies. The examples will include application of superparamagnetic iron oxide nanoparticles for magnetic resonance imaging and drug delivery applications, electrospinning of nanowires for application as electrode materials and vapour phase synthesis of nanolaminates for solar hydrogen production. Finally, the current challenges of integration of nanomaterials in existing device concepts will be discussed.

Title: Regenerative engineering: The theory and practice of a next generation field
Abstract: The next ten years will see unprecedented strides in regenerating musculoskeletal tissues. We are moving from an era of advanced prosthetics, to what I term regenerative engineering. In doing so, we have the capability to begin to address grand challenges in musculoskeletal regeneration. Tissues such as bone, ligament, and cartilage can now be understood from the cellular level to the tissue level. We now have the capability to produce these tissues in clinically relevant forms through tissue engineering techniques. Our improved ability to optimize engineered tissues has occurred in part due to an increased appreciation for stem cell technology and nanotechnology, two relatively new tools for the tissue engineer. Critical parameters impact the design of novel scaffolds for tissue regeneration. Cellular and intact tissue behavior can be modulated by these designs. Design of systems for regeneration must take place with a holistic and comprehensive approach, understanding the contributions of cells, biological factors, scaffolds and morphogenesis.

Title: Next generation diesel particulate filter (DPF) development and implementation strategy
Abstract: Over 30 years have passed since application of the first patent of DPF and over 10 years have passed since the first series production by IBIDEN. During these years there were some progresses in the technology. Recently emission regulation has become stringent more and more regarding both particulate matter (PM) and NOx worldwide. For diesel passenger car (PC), SCR coated DPF system is considered as one of the promising options for future emission after-treatment system by the benefit of downsizing. To integrate the SCR catalyst into DPF, it is necessary to design the DPF substrate so as to have higher porosity and larger pore size compared with the conventional DPF. However it leads to loss of robustness, so by the oxidation layer formed on the SiC particle that composes DPF, we succeeded to improve the strength of DPF substrate. For diesel heavy duty (HD), PM regulation became tighter and DPF has come to be used in EU and Japan. In diesel HD the fuel consumption is emphasized but a demand of robustness is comparatively low. So the effort to realize the low pressure loss substrate has been made with thin wall DPF for future system. In both PC and HD, the roadmap of the exhaust gas after-treatment system can be estimated from the engine characteristics and the regulations. To meet the roadmap, development goals of the substrate and the catalyst are set and the development has been promoted. We studied DPF substrates and SCR solutions that can be leading this field.

Title: Nanocrystalline ceramics: A thermodynamic perspective to enable design and control
Abstract: Nanocrystalline ceramics (nanoceramics) refer to a class of ceramic systems where crystallite sizes are at the nanoscale, such as in nanoparticles, bulk polycrystalline structures, or even composites like metal-ceramics. This class has intrigued the scientific community already for many years due to their unique and unexpected properties that emerge largely from the inherent great interfacial areas in the form of surfaces and grain boundaries. From a thermodynamic perspective, the energetic contribution of interfaces to the total energy of the system is responsible for differences in polymorphisms as compared to bulk microscale, as well as an increased thermo-instability due to elevated driving force for coarsening. Recently, highly sensitive microcalorimetric techniques have been able to depict the energetic contributions from interfaces and enabled quantification of the effects on nanoceramics’ behavior. This creates an unprecedented possibility of designing nanoceramics to meet targeted polymorphs and test mechanisms to increase nanostability on a thermodynamics basis./p>
