The development of carbon dioxide (CO2) separation technology is crucial for mitigating global climate change and promoting sustainable development. In this study, we successfully synthesized an array of cross‐linked poly(vinyl alcohol) (PVA) membranes, xALD‐PEG‐ALD‐c‐PVA, with enhanced CO2/N2 separation performance by employing dialdehyde polyethylene glycol (ALD‐PEG‐ALD) as a cross‐linker. The formation of the cross‐linked network structure not only inhibits the crystallization of PVA but also disrupts hydrogen bonding and thus increases fractional free volume of PVA chains. Under the synergistic effect of these multiple factors, the cross‐linked PVA membranes exhibit a significantly improved CO2 permeability. Moreover, they maintain high CO2/N2 selectivity, attributing to the CO2‐philic characteristic of ethylene oxide groups in the cross‐linked structure. At the ALD‐PEG‐ALD content of 1.6 mmol g−1, the xALD‐PEG‐ALD‐c‐PVA membrane demonstrates a CO2 permeability of 41.4 barrer and a CO2/N2 selectivity of 57.4 at 2 bar and 25°C. Furthermore, compared with the pristine PVA membrane, xALD‐PEG‐ALD‐c‐PVA membranes manifest superior mechanical properties and outstanding separation performance for a CO2/N2 (15/85, vol%) gas mixture. The excellent combination of permeability and selectivity makes xALD‐PEG‐ALD‐c‐PVA membranes highly promising for various CO2 separation applications. [ABSTRACT FROM AUTHOR]

Ciprofloxacin (CIP, C17H18FN3O3), one of the main pollution sources detected in water, has raised intense issues. In order to resolve this issue, it is essential to achieve efficient degradation of CIP under visible light. Herein, a set of two-dimensional composites MoS2/Bi2MoO6 were constructed, and proved via XRD, FT-IR, SEM, TEM, and XPS, respectively. In addition, the results recorded that when the optimized composites 0.5%-MoS2/Bi2MoO6 were applied, the degradation rate of CIP was up to 91% at 120 min under the irradiation of visible light (> 395 nm) which was superior to that of the pure MoS2 or Bi2MoO6. UV–Vis DRS, photocurrent, and electrical impedance analyses indicate that the outperformance of 0.5%-MoS2/Bi2MoO6 is due to the optimized band gap and specific surface area. More importantly, a photocatalytic mechanism was proposed based on the analysis of GC–MS (according to the references (Dang et al. in Chem Eng J 422(15):130103, 2021; Zhu et al. in Environ Sci Pollut Res Int 30(11):28874–28888, 2022)) and active species. The result was manifest: CIP was degraded progressively under the attack of photocatalytically generated h+,.O2−. This work opens up a category for the construction of efficient Bi2MoO6-based composites and proposes a hypothetical mechanism and pathway for CIP degradation. [ABSTRACT FROM AUTHOR]

Purpose: Breast cancer is the most common cancer type worldwide, with its survivors often experiencing physical and psychosocial health problems. Wearable device use is an innovative and effective way to promote physical activity and improve health‐related outcomes in breast cancer survivors; however, the current evidence is unclear. We aimed to determine the effects of wearable devices on physical activity and health‐related outcomes in breast cancer survivors. Methods: PubMed, Embase, Web of Science, and Cochrane Library databases were searched to identify eligible studies from inception to September 2022. Additional relevant studies were obtained from the reference lists of the identified studies. Two reviewers independently screened the eligible studies, appraised the risk of bias, and extracted the data. Meta‐analysis was conducted using Review Manager version 5.3. Findings: Sixteen randomized controlled trials were included. Physical activity tracking and pedometer‐based interventions improved moderate‐intensity physical activity (standardized mean difference [SMD] = 0.32, 95% confidence interval [CI]: 0.17–0.46, p < 0.0001), moderate‐to‐vigorous physical activity (SMD = 0.85, 95%CI: 0.38–1.32, p = 0.0004), total physical activity (SMD = 0.51, 95%CI: 0.12–0.90, p = 0.01), quality of life (SMD = 0.17, 95%CI: 0.03–0.31, p = 0.01), physical function (SMD = 0.21, 95%CI: 0.04–0.38, p = 0.02), and mood state profiles (SMD = −0.58, 95%CI: −1.13 to 0.02, p = 0.04) in breast cancer survivors. However, the effects of low‐intensity physical activity, vigorous‐intensity physical activity, fatigue, anxiety, depression, and sleep quality could not be ascertained. Conclusions: Physical activity tracking and pedometer‐based interventions were effective in increasing physical activity and improving health‐related outcomes in breast cancer survivors. Implications for nursing practice: This review offers availability of credible evidence supporting the potential usefulness and effectiveness of wearable physical activity trackers on physical activity and health‐related outcomes in breast cancer survivors.

Searching for a stable and efficient photocatalyst still presents a variety of challenges, when photocatalytic technology is widely used today. In this paper, oxygen-vacancy BiOCl with different masses was loaded on Bi4O5Br2 nanosheets by a simple two-step method. The UV–Dis spectrum showed that the absorption range of the complex to visible light was larger than that of the two pure substances. In addition, the PL, i – t and EIS characterization prove that the formation of heterogeneous interface between the two materials accelerated the charge transfer in the semiconductor, eventually making photocatalytic efficiency significantly increased. The results showed that the 1 wt.% Ov-BOC@BOB has the best degradation performance, which was seven and four times than that of Ov-BOC and BOB within 120 min, respectively. Free radical capture experiment further confirmed that the charge transfer between oxygen-vacancy BiOCl and Bi4O5Br2 conforms to the Z-type transfer mechanism, such a charge-transfer mechanism would leave behind strongly reducing electrons and strongly oxidizing holes, respectively. The degradation rate of ciprofloxacin (CIP) was not significantly reduced after five cycles of experiments, indicating that the compound had good stability. This study provides a feasible idea for exploring stable and efficient photocatalysts. Z-type heterojunction of BiOCl@Bi4O5Br2 with oxygen vacancy was prepared. The construction of heterostructures facilitates the separation and transfer of photogenerated charges. Free radical capture experiment further confirmed that the charge transfer between oxygen-vacancy BiOCl and Bi4O5Br2 conforms to the Z-type transfer mechanism. [ABSTRACT FROM AUTHOR]
