Summary: This study proposes a self-assembly strategy inspired by biological cooperative and mutual assistance behaviors, to enable the modular space robot to reorganize into different structures with different functions. The strategy utilizes the meta-module method to give nonmobile modules mobility and utilizes mutual assistance to achieve position and posture reachability of the assembly unit. An assembly planner is designed based on the motion characteristics of the meta-module and mutual assistance to obtain assembly sequences for self-manufacturing desired configurations.

Summary: Ultralong hydroxyapatite (HAP) nanowires have potential biomedical applications due to their similarity to bone composition and excellent properties. However, controlling their formation and the long synthesis time have been challenging. This study introduces an eco-friendly microwave hydrothermal method that uses adenosine 5'-triphosphate (ATP) as a bio-phosphorus source and water as the only solvent for rapid synthesis of ultralong HAP nanowires. The resulting nanowires show high flexibility, self-assemble into bundles, and have excellent bioactivity on chitosan scaffolds.

Summary: In this study, a NiO-Co3O4 ultrathin lateral heterojunction was developed using NiCo-based bimetal-organic layers as precursors. The atomic-resolution images revealed a unique continuous semi-coherent interface between NiO and Co3O4, which effectively facilitated electron transfer and raised the d-band center of Co3O4 towards the Fermi level. As a result, the *COOH intermediate could strongly bind on cobalt reactive centers, leading to a remarkable gas yield of 22.67 mmol h-1 in photocatalytic CO2 reduction over NiO-Co3O4. This work highlights the crucial roles of interface engineering in regulating carrier kinetics and surface reactions.

Summary: An S-scheme nanoparticle heterojunction of Co3O4-TiO2/C has been designed to enhance CO2 adsorption and accelerate interfacial electron transfer, thereby boosting photocatalytic CO2 reduction. The in situ confined growth of the nanoparticle heterojunction enables good particle dispersion and a small particle size, which makes the surface and active sites highly exposed and accessible for CO2 molecules. The Co3O4-TiO2/C nanoparticle heterojunction exhibits a higher specific surface area, larger CO2 adsorption capacity, and faster charge transfer compared to pure Co3O4 and TiO2/C, resulting in a significantly higher gas generation rate and remarkable turnover number of the photocatalysis.
