Summary: Compounding carbon substrate materials with pseudocapacitive materials is an important strategy for making high-performance supercapacitor materials. In this study, surface-modified nano carbon black was developed by growing vertical graphene nanosheets on the surface, and MnO2 nanosheets were grown on the modified nano carbon black. The resulting nanocomposites showed high specific capacitance, rate performance, and cycling stability, indicating the potential of this method for the development of new materials for high-performance supercapacitors.

Summary: Mg-ion supercapacitors are promising electrochemical energy storage devices due to their low cost, safety, and long-term cycling stability. However, improving the energy density while maintaining high power density remains a challenge. In this study, cathode CoMn2O4 nanospheres embedded in N-doped graphene were prepared and exhibited excellent electrochemical performance in an aqueous Mg(ClO4)2 electrolyte. The flexible Mg-ion asymmetric supercapacitor showed high capacitance retention after 10,000 cycles, making it a potential candidate for flexible energy storage devices.

Summary: In this study, the BPN-DFO hydrogel was used to treat bone delay union and achieved satisfactory regeneration results in vitro and in vivo. The BPN-DFO hydrogel improved osteogenesis and neovascularization, and the improved bone regeneration was associated with the BMP/Runx2 pathway. This suggests that the BPN-DFO hydrogel has the potential to be a tissue engineering material for ischemic bone defect treatment.

Summary: Autogenous bone grafting is limited in treating critical bone defects due to its drawbacks, thus effective bone substitutes are needed. Inspired by the nacre architecture, a layered nano-hydroxyapatite/chitosan composite scaffold was designed and fabricated. The scaffold promoted osteogenesis and inhibited osteoclast activation, offering a promising platform for bone regeneration.

Summary: The hydrogen storage performance of MgH2 can be effectively improved by doping with a flake Ni nano-catalyst, achieving high hydrogen release and absorption rates at elevated temperatures. The addition of Ni also lowers the activation energies for hydrogen absorption and dehydrogenation, while forming Mg2Ni/Mg2NiH4 on the surface to act as a hydrogen pump, accelerating the reaction rates.

Summary: Electrocatalytic synergy is a functional concept that is often underestimated. This study demonstrates interphasic synergy in monometallic structures, showing the effective interaction between Ni(OH)2 and Ni-N/Ni-C phases for the hydrogen evolution reaction. The development of a Ni(OH)2@Ni-N/Ni-C hetero-hierarchical nanostructure significantly reduces overpotentials in alkaline media, making it a promising strategy for designing electrocatalysts in water splitting and other energy applications.

Summary: This study reports the application of a novel BiFeO3 (BFO)-black TiO2 (BTO) composite (BFOT) as a photocatalyst for the degradation of methylene blue. A p-n heterojunction photocatalyst was synthesized for the first time through microwave-assisted co-precipitation synthesis to increase the photocatalytic efficiency of BiFeO3. Photocatalytic studies on BFOT10, BFOT20, and BFOT30 showed better decomposition of methylene blue compared to pure-phase BFO. The BFOT30 photocatalyst exhibited the highest efficiency in reducing methylene blue under visible light.

Summary: A simple and eco-friendly method of phytic acid-promoted exfoliation of black phosphorus nanosheets (PA@BP NSs) is developed. The resultant PA@BP NSs are conjugated with cationic polyquaternium-2 (PQ), leading to the formation of PA-BP-PQ composite coatings on the polydimethylsiloxane surface. The PA-BP-PQ composite coating exhibits remarkable bi-modal (contact-killing and photothermal) antimicrobial therapy with good biocompatibility both in vitro and in vivo.
