Die Fraunhofer Einrichtung IWKS ist Teil der Fraunhofer-Gesellschaft, die mit über 74 Instituten eine der führenden Organisationen für angewandte Forschung in Europa ist. Die Einrichtung widmet sich der Entwicklung neuer Recycling-Technologien und Substitute für knappe Roh- und Wertstoffe. Zudem werden ressourcenstrategische Studien durchgeführt, um die Verfügbarkeit von Rohstoffen im Gesamtprozess der Gewinnung, Nutzung und Nachnutzung bewerten zu können.

Polymer-derived ceramics (PDCs) can be obtained upon pyrolysis of suitable inorganic polymers in inert or reactive atmosphere.[1-3] An important characteristic of PDCs is the strong relationship between the molecular structure and chemistry of the polymers, their processing and the nanostructure and properties of the resulting ceramics.[2] They are nanoscopically heterogeneous and composed of nanodomains. This feature is controlled by the nature and organization of the segregated carbon formed during the polymer-to-ceramic conversion.[2,4,5] Due to their specific features such as tunable electrical, dielectrical, optical and thermal properties, PDCs can act as multifunctional materials performing multiple functions in a system.[1-5]

In response to the changing global landscape, energy has become a primary focus of the major world powers and scientific community. There has been great interest in developing and refining more efficient energy storage devices. One such device, the supercapacitor, has matured significantly over the last decade and emerged with the potential to facilitate major advances in energy storage. Supercapacitors, also known as ultracapacitors or electrochemical capacitors, utilize high surface area electrode materials and thin electrolytic dielectrics to achieve capacitances several orders of magnitude larger than conventional capacitors [1]. In doing so, supercapacitors are able to attain greater energy densities while still maintaining the characteristic high power density of conventional capacitors.

This project tries to incorporate available magnetization data into the deep learning model so that stable magnetic materials will be predicted, focusing on building a convolutional neural network model on the magnetization.
Expertise will be gained on GPU-computation, coding with Python, and possible experience on sophisticated density functional theory calculations, valuable for both future PhD studies and industrial positions.

In this project massive density functional theory calculations should be carried out to evaluate the thermal conductivities for both 2D and 3D insulators with large band gaps. Particular focus should hereby be on those cases with tunable structural phase transitions.
If time allows there will also be explorative calculations to get the interfacial thermal resistance.
