trans-K3[TcO2(CN)4]

Acta Crystallographica Section E, 2010
The structure of the title compound, tripotassium trans-tetracyanidodioxidotechnetate(V), is isotypic with its Re analogue. The [TcO2(CN)4]3− trans-tetracyanidodioxidotechnetate anion has a slightly distorted octahedral configuration.

An Asymmetric Sodium Extraction/Insertion Mechanism for the Fe/V-Mixed NASICON Na4FeV(PO4)3

Chemistry of Materials, 2022
Vanadium multi redox reactions of V 4+/3+ and V 5+/4+ can contribute to significant capacity gain in positive electrodes for Na-Ion batteries, but the activation of V 5+/4+ redox couple is often accompanied by asymmetric and irreversible electrochemical ...

Magnetotactic Coccus Strain SHHC-1 Affiliated to Alphaproteobacteria Forms Octahedral Magnetite Magnetosomes

Frontiers in Microbiology, 2017
Magnetotactic bacteria (MTB) are morphologically and phylogenetically diverse prokaryotes. They can form intracellular chain-assembled magnetite (Fe3O4) or greigite (Fe3S4) nanocrystals each enveloped by a lipid bilayer membrane called a magnetosome ...

Off‐Stoichiometry Engineering of the Electrical and Optical Properties of SrNbO3 Using Oxide Molecular Beam Epitaxy

Advanced Functional Materials, EarlyView.
The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...
