Due to the complexity of the actual polluted water components, the development of efficient and economical multifunctional materials has great significance and value in the remediation of polluted water. In this study, we have employed MoS2 nanosheets as a carrier to sequentially load magnetic Fe3O4 and ZnO nanoparticles via the electrostatic interaction, yielding a three-in-one MoS2/Fe3O4/ZnO (MFZ) composite nanosheet. The prepared MFZ could catalyze the conversion of H2O2 into hydroxyl radicals (•OH), induce intracellular oxidative stress in situ by nanosized ZnO or Zn2+, and produce photonic hyperpyrexia to promote the catalytic generation of •OH. In vitro antibacterial assays demonstrated that MFZ had high-performance multimodal elimination against Escherichia coli and Staphylococcus aureus in the presence of H2O2 and an 808 nm laser. Moreover, MFZ could also catalyze the rapid degradation of organic pollutants in water including tetracycline (TC), methylene blue (MB), Congo red (CR), methyl orange (MO), and rhodamine B (RhB), which was mainly attributed to the strong oxidization of •OH. Not surprisingly, MFZ displayed satisfactory capacity for killing pathogenic bacteria and removing organic pollutants in real polluted water samples, and importantly, the MFZ could be efficiently recovered by applying an external magnetic field. Therefore, the magnetically recoverable MFZ composite nanomaterial proposed in this work is a versatile and sustainable alternative for future water disinfection and purification.

The article presents the six major economic corridors envisaging as part of the Belt and Road Initiative (BRI) constituting the key framework for regional economic cooperation. Topics include laying a solid foundation for building a community of shared interests, destiny, and responsibility for humankind; focusing on policy coordination, connectivity of infrastructure, unimpeded trade, and financial integration; and facilitating the implementation of different policies for different regions.

Mobile communications have experienced rapid growth in China and play an increasingly important role in the country's economic development. However, there is still vast regional imbalance in China's communications industry which we will be exploring here, including examining what factors influence diffusion paths and cause these differences. Through a two-step estimate method, this paper successfully describes the differences in the diffusion paths of mobile communications in different regions of China. It evaluates the impacts of industry variables, intra-regional income gaps, macroeconomic factors (such as degree of urbanisation) and geographic effects of neighbouring provinces. Our work may be helpful to inform policymaking for effective and equitable development. [ABSTRACT FROM AUTHOR]
