Particles of carbonated barium-calcium hydroxyapatite solid solutions (BaCaHap) with different Ba/(Ba+Ca) (X(Ba)) atomic ratios were prepared by a wet method at 100 degrees C and characterized by various means. The crystal phases and structures of the products strongly depended on

We discovered that micelles of a thermo-responsive polypeptide-based copolymer are able to direct growth of barium carbonate (BaCO(3)) in the form of nanobelts. The BaCO(3) nanobelts tend to grow around a formed crystal, and curl into a spiral superstructure.

In this paper, we report on biomineralization of BaCO(3) hierarchical architectures with self-cleaning ability. The phase structures of the obtained samples were characterized by X-ray diffraction (XRD). All of these complex nanostructures, including dendrite-like nanostructures, dumbbell-like nanostructures, and spherical nanostructures

Nanocrystal superstructures of barium carbonate (BaCO(3)) which exhibit unusual morphologies are obtained by the carbon dioxide vapor diffusion technique in the presence of poly(ethylene oxide)-block-eicosa aspartate (PEO-b-Asp(20)). The highly effective bioconjugate acts as a crystal growth modifier over a broad
