Piezo‐self‐Fenton system (PESF) has been emerging as a promising water treatment technology but suffering from unsatisfied H2O2 production efficiency. Herein, we rationally design a Bi12O17Cl2 piezo‐catalyst with multiple [Bi−O]n interlayers towards highly efficient H2O2 production. The introduction of [Bi3O4.25] layers initiates dual two‐electron pathway for H2O2 generation by altering the interlayer properties. It is found that the additional [Bi3O4.25] layers not only enhance the polarization electric field but also serve as active sites for triggering dual pathways of two‐electron O2 reduction and H2O oxidation reaction for H2O2 production. Therefore, the Bi12O17Cl2 exhibits an ultrahigh rate of H2O2 generation (7.76 mM h−1 g−1) in pure water. Based on the adequate H2O2 yield, a PESF was constructed for acetaminophen (ACE) degradation with an apparent rate constant of 0.023 min−1. This work not only presents a potential strategy of tuning the activity of bismuth based piezo‐catalysts but also provides a good example on the construction of highly efficient PESF for environmental remediation by using natural mechanical energy.

Phosphorus (P) availability in soil is often limited, posing a challenge for sustainable agricultural production. Phosphate solubilizing microorganisms (PSMs) have emerged as a promising biological approach to enhance soil P availability while minimize negative environmental impacts. Exploring the impact of PSMs on increasing soil available P is crucial for optimizing the utilization of insoluble P in soil and promoting sustainable agricultural practices. In this article, we provide a comprehensive review on the dynamics of soil available P, including its input, loss and transformation processes. Additionally, we draw a conclusion about how PSMs increase the availability of P in soil, including solubilizing inorganic P (Pi) and organic P (Po) by secreting substances such as protons, organic acids, inorganic acids, exopolysaccharides, hydrogen sulfide, siderophores and phosphatases. Notably, the factors influencing the P solubilizing activity of PSMs in soil are thoroughly discussed. Moreover, practical applications of PSMs for increasing soil P availability are summarized. Future research should focus on exploring novel PSM isolates, conducting long-term field experiments to assess the effects and potential risk of PSMs under diverse conditions, and investigating synergistic approaches with other P activators or beneficial microorganisms. This review will advance our understanding of PSMs and their practical application, enabling their widespread adoption in agricultural systems. [ABSTRACT FROM AUTHOR]

Osmotic energy, often referred to as "blue energy", is the energy generated from the mixing of solutions with different salt concentrations, offering a vast, renewable, and environmentally friendly energy resource. The efficacy of osmotic power production considerably relies on the performance of the transmembrane process, which depends on ionic conductivity and the capability to differentiate between positive and negative ions. Recent advancements have led to the development of membrane materials featuring precisely tailored ion transport nanochannels, enabling high-efficiency osmotic energy harvesting. In this review, ion diffusion in confined nanochannels and the rational design and optimization of membrane architecture are explored. Furthermore, structural optimization of the membrane to mitigate transport resistance and the concentration polarization effect for enhancing osmotic energy harvesting is highlighted. Finally, an outlook on the challenges that lie ahead is provided, and the potential applications of osmotic energy conversion are outlined. This review offers a comprehensive viewpoint on the evolving prospects of osmotic energy conversion., (© 2024 The Author(s). Advanced Materials published by Wiley‐VCH GmbH.)

Land use plays a critical role in managing water quality in a watershed, as it governs the import and distribution of nutrients. In addition to the land use, some rivers in Southwest China are encountering a new environmental stressor of damming, which is being driven by the national strategy of hydropower development. However, the coupling effect of land use and dams on nutrients remains poorly understood, challenging the effective management of riverine water quality. Therefore, this study examined the nutrients in the Nu, Yarlung Tsangpo (YT), and Lancang (LC) Rivers, which have no dam, 1 dam, and 11 dams, respectively, during different regulatory periods (spring and fall) to identify variations in nutrient control patterns influenced by land use and dams. The findings suggested that an increase in hydropower development contributed to a notable shift in nutrient patterns from land use regulation towards dam regulation and coupling effects. Land use dominated the nutrient variations of the Nu (27.4 %-32.8 %) and low hydropower development YT (25.2 %-30.9 %) Rivers during both seasons, but the primary contributors to the nutrient variations of the high hydropower development LC River were dams (17.9 %-41.6 %) and coupling effects (16.5 %-29.0 %). Dams transform nutrient levels and compositions through internal reservoir cycling, decoupling land use and nutrients. Partial least-squares structural equation model analysis further suggested that the coupling effects of the LC River were seasonal-specific, which was primarily attributed to hydrological variations that affected their interactions. During spring, the reservoir underwent a drainage mode characterized by high-level nutrients in the bottom water. Combined with the import of riverine nutrients, it exacerbated the increase of nutrients (synergistic effect). In contrast, the reservoir transitioned into a storage mode where it intercepted nutrients from the upstream and watershed during the fall, leading to a reduction in the previously observed increasing trend and an increase in nutrient variability (antagonism effect)., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Objective: It aimed to investigate the difference in clinical efficacy between posterior cervical endoscopic discectomy (PCED) and Fenestration laminectomy discectomy (FLD) in cervical disc herniation (CDH)., Methods: This retrospective study analyzed 100 CDH patients undergoing nucleotomy and assigned them into the FLD and PCED groups, 50 cases for each group. The differences in operation time, intraoperative blood loss, skin incision, off-bed time, and hospital stay were evaluated. Numeric rating scales (NRS), Oswestry disability Index (ODI), Japanese Orthopaedic Association (JOA), excellent and good clinical efficacy, quality of life (QoL) SF-36 score, and complication rate were compared., Results: The results showed that compared with the FLD group, the PCED group had increased operation time, decreased intraoperative blood loss, skin incision length, off-bed time, and hospital stay (P < .01). Compared with the FLD group, the PCED group had decreased NRS and ODI scores and increased JOA scores at 1 d, 3 d, 1 month, 3 months, 6 months, 12 months, and 24 months after operation (P < .05). Compared with the FLD group, the excellent and good rate of the PCED group increased significantly after 6 months, 1 year, and 2 years (52.0% vs 64.0%, 58.0% vs. 80.0%, 68.0% vs 90.0%, P < .05). Relative to the FLD group, the physical function, emotional function, vitality, social function, and mental health score of the PCED group increased obviously at 2 years after operation (P < .01). The postoperative complication rate was 0% in both FLD and PCED groups. PCED has good long-term clinical efficacy in the treatment of CDH, with excellent recovery and high safety., Conclusion: PCED showed favorable long-term clinical efficacy in the treatment of CDH, with excellent recovery and high safety. Compared to FLD, PCED resulted in reduced intraoperative blood loss, shorter incision length, and faster recovery. It also led to improved pain scores, functional outcomes, and quality of life measures. The absence of postoperative complications further supports the use of PCED as an effective treatment option for CDH.

Piezo-self-Fenton system (PESF) has been emerging as a promising water treatment technology but suffering from unsatisfied H 2 O 2 production efficiency. Herein, we rationally design a Bi 12 O 17 Cl 2 piezo-catalyst with multiple [Bi-O] n interlayers towards highly efficient H 2 O 2 production. The introduction of [Bi 3 O 4.25 ] layers initiates dual two-electron pathway for H 2 O 2 generation by altering the interlayer properties. It is found that the additional [Bi 3 O 4.25 ] layers not only enhance the polarization electric field but also serve as active sites for triggering dual pathways of two-electron O 2 reduction and H 2 O oxidation reaction for H 2 O 2 production. Therefore, the Bi 12 O 17 Cl 2 exhibits an ultrahigh rate of H 2 O 2 generation (7.76 mM h -1  g -1 ) in pure water. Based on the adequate H 2 O 2 yield, a PESF was constructed for acetaminophen (ACE) degradation with an apparent rate constant of 0.023 min -1 .
