Ceramics and Computing: Modelling, Informatics, Machine Learning and Computational Materials Science: David Smith1; 1IRCER - University of Limoges
Computing in ceramics. Ceramics in computing. The aim of this paper is to explore the intimate relation linking ceramic science and technology with computing. Starting from a historical perspective, four different aspects will be examined: - Instrumentation, - Modelling, - Process control, - Machine learning.In particular, examples giving a European perspective are chosen. Finally future developments and prospects will be considered.

Advanced Microscopy and Data Analysis in Electronic Ceramic Research and Development: Elizabeth Dickey1; 1North Carolina State University
The ability to design the composition and microstructure of electronic ceramics for emerging technological applications requires sophisticated characterization techniques that can provide quantitative information about local structure and chemistry. Such structure quantification is particularly important to the fundamental understanding of properties in many electronic ceramics, where local heterogeneities associated with dopants or intrinsic lattice defects give rise to local inhomogeneities in charge, strain and polarization. Scanning transmission electron microscopy (STEM) provides an invaluable tool for probing such heterogeneities across several length scales, from picometer-scale lattice disorder to nanometer-scale grain boundary and interface segregation. This talk will review recent advances in STEM-based imaging and spectroscopy techniques, as well as advances in data analysis tools, which are driving the development of structure-processing relationships in electronic ceramics. Examples demonstrating the ability of STEM-based techniques to help interpret conductivity and polarization properties of modern electronic ceramics will be highlighted.

Nanochemical Approaches to Materials for Energy and Health Applications
: Sanjay Mathur1; 1University of Cologne
Chemical processing of functional ceramics has played a key role in converging disciplines, which is especially true for their bridge-building role in integrating the concepts of inorganic materials synthesis with fabrication and integration of ceramic device components. This talk will present application of superparamagnetic iron oxide nanoparticles for magnetic resonance imaging (MRI) and drug delivery applications, vapour phase synthesis and electrospinning of nanowires for application as electrode materials and in PEC water splitting reactions. Finally, the current challenges of integration of nanomaterials in existing device concepts will be discussed.

Ceramics in Higher Education Nowadays: New Pedagogical Formats Searching a Balance Between Material and Immaterial: Laura Montanaro1; Tatiana Mazali1; Paola Palmero1; 1Politecnico di Torino
First, an overview of the present European scenario of higher education on ceramics is summarised. Then, some results of innovative teaching experiences, focused on the reinforcement of standard materials engineering curricula by adding hybrid activities, also in non-technical areas, are analyzed. The more and more relevant impact of the digital revolution in the “material” production is discussed. A new relationship between immaterial and material, or even between virtual and real is establishing itself. The progressive spreading of the 3D printing/ additive manufacturing technologies requires a rethinking of the materials and components design, by combining in a synergic way the material culture and the immaterial, digital processes. This transformation is associated to profound implications in applied research, in craft and industrial production, as well as in education: ceramics technology is a paradigmatic example of the need of a new blend between artisan/human creativity and digitalisation, material culture and immaterial tools.

Industrial Refractory Ceramics: Challenges, Innovation and Visioneering: Dana Goski1; 1Allied Mineral Products Inc.
The performance of industrial refractory ceramics plays a critical role in the economic success of many high temperature processing industries. Some of the industry’s current challenges include integration of new materials into commercial manufacturable solutions, quantitatively predicting failure, moving toward clean and sustainable growth, application of computational design, data analytics and Industry 4.0. Challenges, selected innovative solutions and practical visions for the future will be shared.

Dense Powder Beds for AM of Ceramics: Jens Günster1; 1BAM
Many of the most successful and precise additive manufacturing (AM) technologies are based on the deposition layer-by-layer of a flowable powder. Still very important issues remain nowadays, hampering a completely autonomous production of parts and even restricting the freedom of design by means of these technologies. One of the major issues is the low density and stability of the parts during the building process, which implies the need of support structures: The powder bed surrounding the part has an essential role, since it should support the structure during building, until it’s ready for removal. Moreover, the microstructure of the powder bed is a template for the microstructure of the part produced. In this context, the use of submicron ceramic powders is still a challenge. Different approaches for the stabilization and densification of powder beds will be presented.

Advanced Ceramics and Composites for Nuclear Energy – Challenges and Future Prospect: Yutai Katoh1; 1Oak Ridge National Laboratory
Nuclear energy is anticipated to continue contributing to the energy portfolio across the world as one of the important sources of electricity. While the current fleet nuclear power plants demonstrate outstanding reliability, advanced materials are the key enabling technologies to enhance the safety, public acceptability, performance, and sustainability of the nuclear power. For example, silicon carbide-based ceramics and their composite materials are actively considered for fuels, core, and other structural functions in nuclear reactors. However, toward the use of these relatively new materials, there identified significant research and development opportunities. In this presentation, the current status and challenges of ceramic and composite materials technologies for nuclear power will be discussed with the main focus on silicon carbide and its composites. This research is sponsored by the U.S. Department of Energy, Office of Fusion Energy Sciences and Office of Nuclear Energy, under contract DE-AC05-00OR22725 with UT-Battelle, LLC.
