Growth of Millimeter‐Sized BaTaO2N Single Crystals by an NH3‐Assisted BaCl2 Flux Method

open access: yesAdvanced Functional Materials, EarlyView.
Millimeter‐sized BaTaO2N single crystals are successfully grown from a BaCl2 flux under NH3 flow. Their comprehensive characterization, including dielectric properties, is demonstrated, and the possible growth mechanisms are discussed. Abstract Perovskite‐type oxynitrides have attracted considerable attention due to their excellent photocatalytic ...

Insight into the Internal Structure of Biogenic, Synthetic and Geological Apatite by Electron Microscopy and X‐Ray Scattering

open access: yesAdvanced Functional Materials, EarlyView.
Apatite occurs in many forms in nature, e.g. in teeth and geological minerals. Internally, biological apatite contains nanocrystals that are also found in synthetically prepared calcium phosphate nanoparticles which are used in biomedicine, e.g. for gene and drug delivery and for bone regeneration. Abstract Calcium phosphate is the inorganic component (
