“…BaCO 3 has attracted much research recently due to its many essential applications in producing pigments, catalysts, optical glass, and electric condensers [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Moreover, it is a precursor for producing magnetic ferroelectric, superconductors, and ceramic materials [ 8 ].…”

A laboratory-synthesized triblock copolymer poly(ethylene oxide-b-acrylic acid-b-styrene) (PEG-PAA-PS) was used as a template to synthesize hollow BaCO3 nanoparticles (BC-NPs). The triblock copolymer was synthesized using reversible addition–fragmentation chain transfer radical polymerization. The triblock copolymer has a molecular weight of 1.88 × 104 g/mol. Transmission electron microscopy measurements confirm the formation of spherical micelles with a PEG corona, PAA shell, and PS core in an aqueous solution. Furthermore, the dynamic light scattering experiment revealed the electrostatic interaction of Ba2+ ions with an anionic poly(acrylic acid) block of the micelles. The controlled precipitation of BaCO3 around spherical polymeric micelles followed by calcination allows for the synthesis of hollow BC-NPs with cavity diameters of 15 nm and a shell thickness of 5 nm. The encapsulation and release of methotrexate from hollow BC-NPs at pH 7.4 was studied. The cell viability experiments indicate the possibility of BC-NPs maintaining biocompatibility for a prolonged time.

“…which is identified to be one of the potential candidates for a lot of technologically important applications such as microwave devices, spintronics, isolators, circulators and phase shifters, magnetic recording, radar-absorbent materials, permanent magnets, credit cards, etc. [27,28]. Based on the available literature reports of the title ferrite NPs, it could be noted that several polymorphic phases of the barium ferrites have been identified such as BaFe 2 O 4 (Orthorhombic-Cmc2 1 ), Ba 2 Fe 2 O 5 (monoclinic), BaFe 6 O 11 , Ba 3 Fe 2 O 6 (cubic), Ba 7 Fe 4 O 13 (cubic) and BaFe 12 O 19 (hexagonal-P6 3 /mmc) [28].…”

This research work probes into the crystallographic and magnetic structural stability of barium ferrite nanoparticles (BaFe 2 O 4 NPs) at dynamic shock waveexposed conditions. Barium ferrite NPs have been prepared by co-precipitation method and the structural stability of the title ferrite has been scrutinized subsequent to the impact of shock waves (Mach number 2.2) at different counts of shocks viz., 50, 100 and 150, respectively, and their performance on shock resistance has been analyzed by the techniques of X-ray diffraction (XRD), ultraviolet diffused reflectance spectroscopy (UV-DRS), and vibrating sample magnetometry (VSM). Based on the results of the observed analytical measurements, it is substantiated that the test sample has not undergone any of the crystallographic phase transitions even though it has the crystal structure of polymorphism which manifests as the viable witness for the structural stability of the test sample that has been also authenticated by the XRD results. Very few slight changes are observed in the optical and magnetic properties of BaFe 2 O 4 NPs at shocked conditions. More interestingly, the existence of mixed magnetic phase (ferro and anti-ferromagnetic) is witnessed at 50 and 100 shocked conditions because of the shock wave-induced directional disorder of the spin orientations of the test samples which is typically called ''kink behavior''. The observed results reveal that the divalent ferrite NPs of BaFe 2 O 4 have high shock resistance than that of the technologically important ferrites such as ZnFe 2 O 4 and a-Fe 2 O 3 NPs. Hence, the title material could be considered as a prospective candidate for the aerospace device fabrication because of the exceptional stability of its structure against the shock wave impact.
