Alkyl formates as reagents for reductive amination of carbonyl compounds

Alkyl formates in the presence of basic additives can serve as a reagent in the direct reductive amination of carbonyl compounds. The developed procedure can be applied to various aldehydes and ketones with electron donating and electron withdrawing ...

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

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

MAGNETIC ORDERING OF TWO-DIMENSIONAL ANTIFERROMAGNETIC FORMATES

, 1971
La formation de l'état magnétique ordonné de formiate de manganèse et de cobalt est étudiée par des mesures de la chaleur spécifique. Les résultats au-dessous de TN démontrent que le système des spins dans le plan A (100) est ordonné à grande distance et

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

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 ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Alcohols carbonylation to alkyl formates catalyzed by strongly basic resins

, 1998
Heterogeneous basic polymeric resins were checked as catalysts for the carbonylation of methanol and higher alcohols to alkyl formates and their activity compared with that of the conventional homogeneous systems.
