Summary: Hierarchical Co1-xS/MnS/NC nanowires were prepared successfully through a simple hydrothermal reaction and subsequent annealing of one-dimensional coordination polymer precursors. The heterostructure nanowires not only act as a buffer for volume expansion during charging and discharging but also significantly enhance electronic conductivity, leading to improved rate performance and cycling stability. The nanowires maintain a high capacity of 612.9 mA h g(-1) after 100 cycles at 0.5 A g(-1) and 544.6 mA h g(-1) after 200 cycles at 1.0 A g(-1) for SIBs.

Summary: Cu-based electrocatalysts with surface reconstruction play a crucial role in CO2 conversion into multicarbon hydrocarbons. Polycrystalline Cu nanoparticles with high-index facets derived from Cu2-xS showed excellent CO2 conversion performance. In situ X-ray absorption spectroscopy and OH- adsorption characterizations were used to study the changes in electrocatalytic performance during the two stages of desulphurization and surface reconstruction.

Summary: A novel light-triggered shape memory composite was reported by incorporating renewable biomass-derived carbon nanomaterials into acrylate polymers, without the need for deep purification. The functionalized carbon nanomaterials not only had stable dispersion in polymers, but also enhanced the mechanical properties of the composites by forming hydrogen bonds between the carbon nanomaterials and the polymers. Additionally, the composites exhibited excellent and stable thermal and photothermal responsive properties, making them promising candidates for shape memory applications in smart fabrics and intelligent soft robotics.

Summary: Compared with heterojunction composite, the heteroparticle provides a larger interfacial area between components and higher photoactivity. However, it is difficult for two or more substances to form synchronously on an individual particle due to their different thermodynamical property and stability. In this study, sulfonic resins are used to in-situ prepare the ternary Cu-Cu2-xS/C catalyst, which accelerates the electron transfer between Cu and Cu2-xS and exhibits superior photocatalytic activity for the reduction of Cr(VI).

Summary: This study proposes a method to synthesize a Mn2+- coordinated polymer precursor ligated by sulfur atoms with acetate counter ions. MnS/MnO decorated N, S-doped carbon nanoparticles are prepared by calcination of the Mn ion-coordinated polymer for the practical applications of catalytic reactions. The performance of the nanoparticles in catalytic oxidation reactions is mainly related to the MnO decorated outside the SNC particles compared to MnS formed inside the particles.

Summary: This study demonstrates that the energy consumption and costs associated with adsorbent regeneration in carbon capture can be significantly reduced by using photo-responsive hypercrosslinked polymers recycled from waste expanded polystyrene. UV light is used to enhance CO2 adsorption and visible light is used for desorption, showing good reusability. The low energy footprints and synthesis and operating costs of these photo-responsive polymers have the potential to reduce carbon capture costs and establish a green carbon capture process driven by light.

Summary: This study investigated the metabolic changes in host-microbial co-metabolism and gut microbiome in mice after infection with carbapenem-resistant Escherichia coli (CRE). Significant alterations in metabolites were observed in the feces and serum of the CRE group, as well as changes in the relative abundance of certain bacterial taxa. Furthermore, association analyses revealed specific bacterial taxa associated with the changes in fecal and serum metabolites. This study offers insights into the early-stage interactions between gut microbiota and host metabolism during CRE infection, potentially leading to innovative diagnostic and therapeutic strategies.

Summary: This paper examines whether prospect theory can explain stock market participation using panel data from a nationally representative survey in China. The empirical results show that individuals use expected income as a reference point when making investment decisions, with relative losses motivating excessive risk-taking and relative gains increasing risk aversion. These findings provide insights into the limited stock market participation among low-income individuals and the unwillingness of high-income individuals to hold stocks.

Summary: This paper evaluates the impact of a large-scale school meal program in rural China on the health and nutritional status of students aged 6-16 in compulsory education. The results show that program participation is associated with a higher child height-for-age, particularly among students in better health condition. However, the impact on the most disadvantaged students is small or not significant. There are no significant differences in effects across individual and household characteristics. The study suggests that more support is needed to achieve broader impacts that effectively reach all vulnerable students.
