Summary: Freshwater scarcity is a critical global challenge, and atmospheric water harvesting (AWH) shows great promise for addressing this problem. Mesh-based fog harvesters have gained attention for their passive qualities, but their water yield has only developed modestly. Scientific understanding of passive fog collection processes is advanced, but practical application at scale still faces challenges. However, with advancements in manufacturing technology, particularly in mesh design, there are opportunities for further development.

Summary: To prevent the instability and safety risks of a post-capture spacecraft caused by vibrations and drifting motions, the proposed quadrilateral shape isolation system with an energy harvester is capable of simultaneously achieving broadband vibration isolation and energy harvesting. The operation principle is the energy localization effect, which is demonstrated through system dynamics investigation. Improvement guidelines for the dual performances are proposed based on parametric studies on mass ratios, equivalent stiffness and damping induced by quadrilateral shape structures, and mechanical and electrical parameters of the energy harvester.

Summary: A study designed and prepared MR-targeted glycosylated nano-hydroxyapatites (GHANPs) to reprogram macrophages into polarized M2s, promoting bone regeneration. The GHANPs induced macrophage M2 polarization and enhanced osteoblastic differentiation of stem cells. Mechanistic studies suggested that GHANPs might influence macrophage polarization through modulating cell metabolism. In vivo experiments using a rat cranial defect model demonstrated that GHANPs promoted bone regeneration and increased the ratio of M2/M1 macrophages during early bone repair. This study indicates the promising potential of the MR-targeted macrophage M2 polarization strategy in endogenous bone regeneration.

Summary: Intrinsic and dandelion-like microflower nano-rod structures of boron-doped ZnO thin films were successfully synthesized using an ecofriendly and cost-effective chemical bath deposition technique. The doping of boron decreased the optical band gap of ZnO and affected the arrangement of crystallites. The 1% B-doped ZnO film showed the lowest activation energy at both low and high temperatures, suggesting potential applications in gas sensors and solar cells.

Summary: The Laporte rule states that one- and two-photon absorption spectra of symmetric molecules should display alternatively forbidden electronic transitions. However, for organic fluorophores, the distinction between symmetric and non-inversion symmetric two-photon spectra is often unclear due to vibronic interactions. In this study, we use protonation to break and then reconstitute inversion symmetry in a symmetric diketopyrrolopyrrole, resulting in significant changes in two-photon absorption. Through experiments and calculations, we explain how low-frequency vibrational modes can lead to deviations from the Laporte rule and propose the system as an inversion symmetry switch for two-photon sensing applications.
