Application of Machine Learning to Mechanical Properties of Copper Graphene Composites [PDF]
arXiv, 2022 While copper-graphene (Cu/Gr) composites have been promising materials due to their theoretically high strength and conductivity, their design has been hampered by the large number of variables affecting their properties. We applied four different Machine Learning (ML) models to manually collected datasets compiling the yield strength and ultimate ...

KupferDigital: Ontology‐Based Digital Representation for the Copper Life Cycle
Advanced Engineering Materials, EarlyView.It is demonstrated how data from different stages in the life cycle of a copper product can be stored in an ontology‐based data space. In order to showcase the methods and tools used in the project, four use cases are presented that show how data from different sources can be semantically described and queried from a shared data space.

Polycrystalline MnBi as a transverse thermoelectric material [PDF]
arXiv, 2022 To assess the potential of polycrystalline MnBi as a transverse thermoelectric material, we have experimentally investigated its anomalous Nernst effect (ANE) by means of the heat flux method. We prepared MnBi samples by powder metallurgy; this technique allows the preparation of samples in arbitrary shapes with the possibility to tailor their magnetic
