High-temperature processes related to energy conversion, industrial production and trans-portation cause the major part of the anthropogenic CO2 emissions and are, therefore, re-quired to be improved further. Thereby, advanced high-temperature functional materials play a key role in enabling increased operation temperature, life time and efficiency.

The symposium focuses on the close relationship between functionality of high-temperature materials and operation principles for application temperatures above 350°C. The presenta-tion of new materials and methods will be especially acknowledged. The contributions should include recent scientific and technological results on high-temperature materials related to their design, fabrication and application including miniaturized, wireless or micromechanical devices. Contributions should cover the following areas:

  • Novel and emergent materials for fuel cells, turbines and combustion systems,
  • Materials for gas, pressure and temperature sensors
  • Actor materials and integrated sensor actor systems
  • Active piezoelectric and electronic structures
  • Functional coatings including catalysts
  • Compatibility of functional materials

Surface engineering is a sub-discipline of materials science, which deals with the surface of solid matter. Applications can be found for example in chemistry, mechanical as well as and electrical engineering. Solids are typically composed of a bulk material covered by a surface, which acts as an interface to the surrounding environment. The surface layer can be affected by mechanical, thermal or chemical process effects and can be characterized by topography, residual stresses, work-hardening state and other microstructural changes. Additionally the effects on component service properties like fatigue, corrosion or wear resistance must be evaluated based on the mechanisms beyond. This symposium will include topics, which deal with such correlations and draw the attention to manufacturing processes from casting via forming, machining and removal, surface modification by heat, chemical, laser and plasma treatments as well as mechanical surface treatments, and coatings deposition.

Advances in functional materials are decisive in addressing current challenges for energy conversion. Thermoelectricity allows for the conversion of heat to electricity and vice-versa. In this symposium, we aim to cover all aspects of recent thermoelectric developments related to the materials synthesis and processing, thermoelectric properties measurements, calculations and simulations, design and fabrication of devices. Invited and contributed presentations will provide state-of-the-art research achievements in thermoelectricity. This symposium will be multidisciplinary as it will gather scientists from physics, chemistry, materials science and engineering fields of research.

We will provide a platform for discussion among scientists working at the forefront of mix ionic electronic conducting oxides for electrochemical conversion technologies: solid oxide fuel cells (SOFC) and membranes (ME). Works dealing with novel oxides and engineered microstructures such as composites, superlattices or core-shell materials will be encouraged. Thin film and bulk communities will be brought together to promote the exchange of knowledge and networking opportunities.

In future, the separation of energy generation and energy consumption is the precondition for flexible, decentralized and mobile energy concepts. Electrochemical energy storage systems will play an outstanding role due to their high degree of efficiency and the flexible application possibilities. The key challenge in the context of new electrochemical energy storage devices is the development of improved materials which are adjusted to specific applications. Common electrode materials can be modified in various ways to achieve an enhancement of thermal, mechanical, and chemical stability as well as improved electronic and ionic conductivity. This symposium addresses both experimental and theoretical work dealing with the design of electrochemical energy storage materials such as effect of doping elements; hierarchically structured materials; characterization and modelling of 3D structures; measurement of the electronic and ionic conductivities; process-structure-property relations; simulation methods for battery cells.

The unsustainability of our fossil fuel based society and economy is at the beginning of its end, as indicated by the recent advent of the Anthropocene epoch. Today, the critical supply of primary and secondary resources directly impacts the development and cost of advanced materials which form the basis for a number of latest green energy technologies. These technologies are in particular but not exclusively: Batteries, solar cells, fuel cells, catalysts, chemical energy conversion, thermoelectrics and magnets for e-mobility, wind turbines and refrigeration. The efficient utilisation or substitution of strategic metals with more sustainable and earth abundant elements is the big challenge for the Great Transition.
We invite contributions addressing the various levels of substitutionability and recyclability of critical elements in the different classes of functional materials. The aim is to develop new materials and efficient energy technologies with a reduced supply risk and enhanced environmental and social sustainability.

Research and development for advanced lithium and post-lithium (Na-, Mg-, ..) batteries require an integrated understanding of the materials´ electrochemical properties, the thermodynamic and kinetic behavior as well as the relationships to thermal and safety performances. This symposium will focus on both the individual properties of advanced battery materials and their behavior within cells and batteries in operation (regular and irregular uses, accidents). Besides materials electrochemical, thermodynamic and kinetic data, their heterogeneous reactions are of interest. Additionally, contributions are invited considering micro- and nanostructural properties and crystal chemistry of electrode materials e.g. related to environmental conditions and cell operating modes. Presentations will cover recent results from experimental investigations, theoretical approaches and simulations (ab initio, Calphad, phase field, …).

The structure of interfaces plays a key role in processing and performance of crystalline functional materials, such as sensors, ferroelectric actuators, dielectrics and ionic conductors. Mechanics of materials are affected by interfacial properties as well, e.g. in the case of dislocation-grain boundary interaction. However, not only the properties of materials depend on interfaces, but the formation of a microstructure as well, i.e. sintering and grain growth. Possible impact on microstructure and its evolution arise due to the boundary structure, local defect redistribution, segregation, space charge, mechanical stresses and the anisotropy of transport processes at interfaces. These effects and their interplay with the materials properties need to be understood on a fundamental level in order to optimize a material and its microstructure for a given application.
This symposium covers basic and applied science topics on all aspects of interfaces, microstructure evolution, thermodynamics and their relationship to the materials properties in functional materials. According to the complexity of this field, a complete understanding needs modelling and simulation studies corresponding to experimental research. Talks bridging the gap of experiments and simulation are highly encouraged. The overall focus is on functional ceramics, but other crystalline materials are considered as well.
