Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

Advanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Visible Opacities of S-type Stars: The d 3Φ–a 3Δ Band System of ZrO

The Astrophysical Journal
ZrO is a well-studied metal monoxide because of its astrophysical importance in characterizing S stars. The bands of the d ^3 Φ–a ^3 Δ system ( γ system) with ${v}^{{\prime} }\leqslant 4$ and v ″ ≤ 5 are rotationally analyzed using the PGOPHER program to

Theoretical determination of the spectroscopic constants of the MgC molecule

The Astrophysical Journal, 1991
The results for the spectroscopic constants of MgC obtained from full fourth-order many-body perturbation theory calculations are reported. Potential energy curves are shown along with finite-difference numerical restricted Hartree-Fock results for the dipole moment of MgC.

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

Advanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an
