MaterialDigital Initiative

The cover image illustrates the concept of advancing digital transformation within the MaterialDigital Initiative through workflows, as discussed in article number 2402149 by Jörg Schaarschmidt and co-workers. The projects within this initiative utilize various concepts and tools, applied to a broad range of material classes. A digital library, the PMD Workflow Store, has been established to disseminate these workflows enabling FAIR principles. The image shows an examplary workflow developed within StahlDigital, discussed in detail in article number 2402148.

Digitalization in Materials Science

Advanced materials solutions in innovative products require an intensive information and data exchange about materials along the entire value chain. The increasing digitalization of materials science, engineering and technology affords a highly reliable, fast exchange of data between different players. This special issue covers progress in the digital representation of materials and its adoption in academia and the industry. Further information can be found in the Guest Editorial by Peter Gumbsch and Pedro Dolabella Portella (article number 2500484).

Semantic Data Integrations

Data management in materials science traditionally relies on independent databases, making cross-domain analysis challenging due to the magnitude, diffuse character, and lack of specificity of relevant data. In article number 2401092, Bernd Bayerlein and co-workers discuss how subdomain data spaces—represented by ascending blocks—unlock their potential, making knowledge more visible, accessible, and interoperable. Semantic Web technologies enable structured access to heterogeneous data, tools, and knowledge through ontologies and cross-domain knowledge graphs.

Material Digital

The Initiative MaterialDigital was launched to bring together the emerging academic abilities and industrial needs for materials data in a federated national infrastructure. It comprises a central Platform MaterialDigital and a series of joint projects. Connected to the Platform the projects work on distinct materials systems, production chains and applications. This special issue (article number 2500484) presents the main results of these projects, fundamental work of the Platform and some related work.

NFDI-MatWerk

The vision of NFDI-MatWerk is to establish the leading and sustainable data infrastructure for Materials Science and Engineering, enabling seamless access to high-quality data and fostering a collaborative research environment. It is expected to connect new and existing tools and services via an interoperable workflow space described by harmonized semantics (article number 2500484).

Implantable Devices

In article number 2402632, Se Jin Oh, Amy Kyungwon Han, and co-workers present a superior vena cava (SVC) compressive shape-memory-alloy (SMA) implantable device, “SCS,” that is wrapped around the SVC and installed to regulate venous return in acute decompensated heart failure (ADHF). The SCS device operates through biocompatible SMA actuators and offers a potential long-term solution that minimizes thrombosis risk by avoiding direct blood contact, representing a significant advancement over current ADHF treatments.

Polymer Composites

In article number 2402179, Suprakas Sinha Ray and co-workers review the development of conductive inks derived from 2D nanomaterials. The work specifically explores how the addition of 2D nanomaterials, such as graphene and transition metal dichalcogenides, alters the rheology of different polymers for 3D printing. S. S. Ray designed the cover art in collaboration with the team at INMYWORK Studio.

The copper life cycle comprises numerous stages from the alloy production to the manufacturing and usage of engineered parts until recycling. At each step, valuable data are generated and stored; some are transferred to the subsequent stations. A thorough understanding of the materials’ behavior during manufacturing processes or throughout their product lifetime is highly dependent on a reliable data transfer. If, for example, a failure occurs during the service life, information about the manufacturing route can be of decisive importance for detecting the root cause of the failure. Additionally, the life cycle assessment hinges on the availability of data. Recording and storing interoperable structured data is, therefore, a thriving research field with huge implications for the economic strength of the manufacturing industry. In the KupferDigital project, it is demonstrated how an ontology-based data space can be utilized not only as an innovative method for storing and providing interoperable life cycle data but also as a means to enable automated data analysis and evaluation, leading to new insights and the creation of new knowledge using semantic data and technologies. This work illustrates how data recorded at different research facilities can be integrated into one single data space, allowing queries across heterogeneous sources.
