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

Chemical communications (Cambridge, England), 48(68), 8544-8546 (2012-07-19)
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.

Inorganic chemistry, 48(21), 10326-10329 (2009-09-29)
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

In December 2003, the USEPA released an amended list of 15 "candidate pollutants for exposure and hazard screening" with regard to biosolids land application, including Ba. Therefore, we decided to monitor soil Ba concentrations from a dryland wheat (Triticum aestivum
