They also synthesized BaTaNaVO, but structural refinement was absent.

We report on a spiral structure suitable for obtaining a large optical response. We constructed a structural mechanics model of the shape of the planar spiral structure when deformed and verified the effectiveness of the model. As a verification structure, we fabricated a large-scale spiral structure that operates in the GHz band by laser processing.

- Understanding reaction pathways is crucial for optimizing solid-state reactions, which have been challenging to study due to their complexity and technical limitations.
- Using advanced synchrotron X-ray techniques, researchers explored solid-gas reduction mechanisms in layered perovskite SrFeO, highlighting its potential as an environmental catalyst.
- The study found that while pristine SrFeO shows a predictable structural evolution, a Pd-loaded sample experiences a sudden change in its reaction pathway just before a phase transition, indicating a shift in the rate-determining step of the reaction.
