Symposia

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.

Ferromagnetic shape memory alloys (FSMA), piezoelectric (PZT) and multiferroic materials are functional materials of both high basic and technological interest. FSMA and PZT materials are widely used in different technological applications as, actuators, motors, sensors, benders, etc. Multiferroic materials have great potential for data storage application in hard disks.
Advances in FSMA are considered which focus on the role of internal stresses and quenched-in-defects on variants mobility and thermoelastic equilibrium for a modification of the martensitic transformation characteristics. In addition, great attention is paid on the potential application of the inverse magneto caloric effect for refrigeration.
Besides this, new results regarding to studies concerning to PZT, (type I and II) multiferroic and other functional materials are also welcome. 
In addition, novel experimental techniques for producing and characterizing these materials are of interest for this symposium

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, …).

Superconducting materials are an enabling technology for future sustainable energy production, transport and storage. Superconducting cables, motors/generators, magnet systems, bearings and many more applications are currently being developed. 
Over the last 30 years, several new medium and high-temperature superconducting materials have been discovered including the cuprates, MgB2 and Fe-based compounds. Nonetheless, significant effort is still required to develop new and better superconducting composite materials for energy applications and to develop cost-effective materials processing, micro-fabrication and cryogenic technologies. Moreover, identifying and improving vortex pinning mechanisms in these superconductors is a key enabler of enhanced critical current and consequently better real work performance, especially at high magnetic fields.
This symposium aims to bridge the gap between materials science and electrical engineering with a strong focus on energy-relevant applications and materials. This symposium will provide a forum for scientists and engineers at all levels from academia and industry to share their ideas, experiences, and latest research results.

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.
