The advanced techniques of synchrotron radiation x-ray diffraction (SRXRD) and electron spin resonance (ESR) are used to analyze the size effects on their magnetic/superconducting...

Different morphosynthesis strategies for BaCO3 using natural polysaccharide-gum acacia (GA) as templating species are presented. The influence of GA with different functionalities such as -OH,...

BaCO3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.78–2.91 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. All C–O bond lengths are 1.30 Å.

Barium carbonate (BaCO3) materials with the controllable morphology of nanoparticles were selectively loaded into the lumen halloysite nanotubes (abbreviated as Hal) by a urease assisted...

BaCO3 crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two BaCO3 sheets oriented in the (0, 0, 1) direction. Ba2+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms.

Jul 1, 2008 · The BaCO 3 nanorods and nanoparticles have been characterized by X-ray powder diffraction (XRD), IR spectroscopy and also the morphology and size of the nanostructures have been observed by scanning electron microscopy (SEM).

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).

Jan 1, 2018 · The XRD peaks of BaCO 3 are in agreement with the orthorhombic structure and space group of Fd 3 ̄ m (JCPDS card 44-1487). In addition, the reaction between BaCO 3 and SnO 2 led to the formation of small amounts of an intermediate phase, cubic BaSnO 3 as indicated by the XRD line (110).

Jun 30, 2008 · A rational mechanism of rod-like shape assembled from nanoparticles was proposed. The products were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and selected area electron diffraction (SAED).

This simple method for fabricating novel BaCO3 nanostructures is presented here. X-ray diffraction was indexed on the orthorhombic polycrystalline structure of the prepared BaCO3.
