Summary: A facile and robust interface reaction method was developed for the controllable synthesis of hierarchically structured flower-like MnO2 hollow microspheres at a low cost. The as-prepared flower-like MnO2 hollow microspheres exhibited excellent low-temperature catalytic activity for toluene oxidation due to their high specific surface area, abundant oxygen vacancies, high content of Mn4+, numerous acidic sites, and strong acidity. This work provides a new strategy for the facile construction of high-performance volatile organic compounds oxidation catalysts with industrial application prospects.

Summary: Silica hollow microspheres were prepared as biocompatible cell carriers using emulsified gelatin microspheres as sacrificial templates. SEM observations showed their spherical morphology with a hollow structure and a diameter of 50-200 μm. FT-IR spectrum revealed the presence of Si-O-Si bonds. Gelatin microspheres served as supporting matrix and sacrificial templates for the formation of hollow structure. The silica hollow microspheres were found to be biocompatible and supported cell attachment and proliferation when seeded with osteoblast MC3T3-E1 cells, indicating their potential as biocompatible cell carriers.

Summary: In this study, the distribution of rotigotine in golf ball-shaped microspheres (GSRM) was investigated. It was found that rotigotine existed in aggregated form and molecularly dispersed form in the microspheres. The distribution of palmitic acid in the microspheres was also demonstrated, with 10% on the microspheres' surface and 90% as small particles inside the microspheres. The release of rotigotine from GSRM involved the dissolution of phase-separated particles followed by osmotic release of molecularly dispersed rotigotines. The study established correlations between in vitro release testing and in vivo performance of GSRM.

Summary: This study investigated the stabilization mechanism of Pickering emulsion using mesoporous hollow silica microspheres (MHSMs) as stabilizers. The results showed that smaller particle size and shell thickness of MHSMs can improve the stability of Pickering emulsion, and MHSMs with intermediate hydrophobicity and suitable oil/water ratio are favorable for stability. Increasing the concentration of MHSMs within a certain range can enhance the stability of Pickering emulsion, with the optimal concentration being 1.25 mg/mL. This research opens up possibilities for the fabrication of functional materials through Pickering emulsions.

Summary: Designing hybrid metal sulfide-based anode materials is an effective method to enhance the performance of sodium-ion batteries (SIBs). However, the capacity of sulfide-based anodes decreases significantly due to volume expansion during charge/discharge processes. In this study, concaved NiS2@CoS2 nano-cubes (NCSC) were successfully prepared through chemical etching of Ni-Co coordination polymers (NiCoCP) precursor. The obtained NCSC anode materials exhibited a high specific sodium storage capacity of 848 mAh g-1 at 0.1 A g-1 and a stable cyclability of 572 mAh g-1 at 5 A g-1 after 830 cycles. This unique etching strategy provides a novel approach for the design and fabrication of high-performance anode materials for SIBs.

Summary: In this study, a vanadium dioxide/ graphene oxide (VO2(B)/GO) sample was constructed through hydrothermal route, which exhibited remarkable rate capability. The presence of oxygen vacancies in VO2(B)/GO weakened the electrostatic force, while GO prevented vanadium oxidation. The electrode showed a high reversible capacity of 423 mAh g-1 at 0.5 A g-1 and maintained long-life cycling properties at 15 A g-1. The combination of oxygen vacancies and GO contributed to excellent performance and prevented the collapse of VO2 structure during cycling. VO2(B)/GO also exhibited excellent performance in all-climate conditions (-15-60 degrees C).

Summary: Heterogeneous bimetallic sulfides Bi2S3/Mo7S8 nanoparticles anchored on MXene nanosheets (MXene@Bi2S3/Mo7S8) were prepared and exhibited remarkable rate capability and cycling stability for sodium ion battery. The unique structure between Bi2S3 and Mo7S8 and the high conductivity of Ti3C2Tx nanosheets effectively decreased the Na+ diffusion barrier and charge transfer resistance. The hierarchical architectures of Bi2S3/Mo7S8 and Ti3C2Tx also prevented re-stacking and agglomeration, as well as alleviating volume expansion during charge/discharge processes.

Summary: The recycling of thermosetting polymers, which cannot be reprocessed due to their covalently cross-linked structures, can be achieved through the implantation of dynamic covalent bonds. This study demonstrates the direct and catalyst-free ester metathesis of N-acyloxyphthalimide (NAPI) and its use in the creation of covalent adaptable networks (CANs). The NAPI metathesis reaction shows interesting kinetics, proceeds via a free radical chain mechanism, and allows for fast associative exchange at low dissociation.

Summary: Nickel/cobalt bimetallic nanocrystals were successfully synthesized by annealing the core-shell structure precursor. These nanocrystals demonstrated excellent catalytic activity in converting solid lithium sulfide into soluble lithium polysulfides and significantly reducing the energy barrier. The incorporation of hierarchically structured CNT-porous carbon frameworks allows for fast electron/ion transport due to their large surface area and active sites exposure. These nanocrystals, when used as a separator modifier in lithium-sulfur batteries, exhibit improved battery properties such as high specific capacity, outstanding rate capability, and long-term cycle stability.
