“…BaCO 3 is also used in tuning the optical properties of rare earth materials, which have wide applications in biomaterials, lasers, light-emitting diodes, and optical communication. It is considered as one of the favored host materials for lanthanide doping [ 14 , 15 ]. It brings new physical and chemical stability, high transparency, and good moisture resistance properties.…”

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.

“…Although some successes have been achieved for carbon coating, the high rate capacity is still need further improvement because of the low Li ion transfer [22,23]. Introducing the porous structure into the electrode material could effectively provide Li ion rapid transfer channels to enhance rate capability of electrode materials, where the introduction of the porous structure could also provide large space to accommodate volumetric changes during electrochemical cycling [26][27][28][29][30][31][32].…”

Transition metal oxides have attracted lots of interest for lithium ion battery (LIB) due to the high theoretical capacity, however, the large specific volume change, low electrical conductivity and slow intrinsic lithiation/delithiation still limit the practical applications. In order to overcome the challenge, a novel type of high temperature annealing treatment for the synthesis of 3D porous FeOx nanocrystals embedded in a partially carbon matrix as an example for high-performance LIB is reported. The FeOx/carbon nanocomposites with coral-like architecture achieved at 700 °C (F700) exhibit good long term cyclability with a reversible capacity 1012 mAh g−1 remain after 500 cycles at 1.0 A g−1 and the high rate capacity with a reversible capacity of 233 mAh g−1 even at extremely high current density of 20 A g−1. These excellent electrochemical performances could be attributed to the 3D porous structure and carbon coating, which could not only provide excellent electronic conductivity and enough elastic buffer space to accommodate volume changes upon lithium insertion/extraction, but also effectively avoid agglomeration of the Fe3O4 nanocrystals and maintain the structural integrity of the electrode during the charge/discharge process.
