K3NbF7's electrochemical characteristics in the NaCl-KCl molten salt system at the Mo electrode

Electrochemistry Communications
To explore the electrochemical behavior of Nb (IV) for form Nb metal, molten salt electrolysis was carried out in an NaCl-KCl melt containing K3NbF7 at 750 °C. It was discovered that Nb (IV) reduces in three stages: Nb(IV)➔Nb(III)➔Nb(II)➔Nb，and reduction

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Heavy metals in paddy fields in Taiwan: chemical behavior in soil and uptake by brown rice [PDF]

, 2009
Levels of cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) were measured in 19 individual paddy fields in Taiwan. Total, reactive, and available metal levels were measured using Aqua Regia, 0.43 N HNO3, 0.1 M HCl, 0.05 M ...

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

Present and potential future recycling of critical metals in WEEE [PDF]

, 2014
This report details current and potential recycling of critical metals in Waste from Electrical Electronic Equipment (WEEE). The term "critical metals" is used instead of "rare metals" because the concept incorporates not only supply but also demand. The

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 ...
