Solar‐driven CO2 reduction into value‐added C2+ chemical fuels, such as C2H4, is promising in meeting the carbon‐neutral future, yet the performance is usually hindered by the high energy barrier of the C─C coupling process. Here, an efficient and stabilized Cu(I) single atoms‐modified W18O49 nanowires (Cu1/W18O49) photocatalyst with asymmetric Cu─W dual sites is reported for selective photocatalytic CO2 reduction to C2H4. The interconversion between W(V) and W(VI) in W18O49 ensures the stability of Cu(I) during the photocatalytic process. Under light irradiation, the optimal Cu1/W18O49 (3.6‐Cu1/W18O49) catalyst exhibits concurrent high activity and selectivity toward C2H4 production, reaching a corresponding yield rate of 4.9 µmol g−1 h−1 and selectivity as high as 72.8%, respectively. Combined in situ spectroscopies and computational calculations reveal that Cu(I) single atoms stabilize the *CO intermediate, and the asymmetric Cu─W dual sites effectively reduce the energy barrier for the C─C coupling of two neighboring CO intermediates, enabling the highly selective C2H4 generation from CO2 photoreduction. This work demonstrates leveraging stabilized atomically‐dispersed Cu(I) in asymmetric dual‐sites for selective CO2‐to‐C2H4 conversion and can provide new insight into photocatalytic CO2 reduction to other targeted C2+ products through rational construction of active sites for C─C coupling.

We conducted a meta-analysis of 13 randomized trials comparing the efficacy of rosuvastatin versus atorvastatin in reducing concentrations of C-reactive protein (CRP). We searched PubMed, Ovid, and Elsevier databases until June 2014. Search terms included C-reactive protein or CRP, rosuvastatin, atorvastatin, randomized, randomly, and randomization; 13 trials (3798 patients) were included. Funnel plots for CRP were inspected to assess publication bias. The pooled analysis demonstrated the benefit of rosuvastatin over atorvastatin therapy for all 13 trials (mean difference [MD] = −0.11, which is standardized mean with no unit although the raw data before pooling is mg/L, 95% confidence interval −0.15 to −0.07, P < .0001) with no evidence of significant publication bias (I2 = 6.9%, P = .377). Subgroup analysis indicated a significant benefit of rosuvastatin over atorvastatin regarding the 1/1 dose ratio (MD = −0.14, 95% CI −0.21 to −0.06) and 1/2 dose ratio (MD= −0.11, 95% CI −0.16 to −0.05). Cumulative and influence analyses showed accuracy and stability for the estimation mentioned earlier. Our meta-analysis shows that rosuvastatin produces better reduction in CRP concentrations than atorvastatin at a dose ratio of 1/1 and 1/2 (rosuvastatin/atorvastatin), respectively.

Selective CO2 photoreduction to hydrocarbon fuels such as CH4 is promising and sustainable for carbon‐neutral future. However, lack of proper binding strengths with reaction intermediates makes it still a challenge for photocatalytic CO2 methanation with both high activity and selectivity. Here, low‐coordination single Au atoms (Au1‐S2) on ultrathin ZnIn2S4 nanosheets was synthesized by a complex‐exchange route, enabling exceptional photocatalytic CO2 reduction performance. Under visible light irradiation, Au1/ZnIn2S4 catalyst exhibits a CH4 yield of 275 μmol g−1 h−1 with a selectivity as high as 77 %. As revealed by detailed characterizations and density functional theory calculations, Au1/ZnIn2S4 with Au1‐S2 structure not only display fast carrier transfer to underpin its superior activity, but also greatly reduce the energy barrier for protonation of *CO and stabilize the *CH3 intermediate, thereby leading to the selective CH4 generation from CO2 photoreduction.

Light-driven oxidative coupling of methane (OCM) for multi-carbon (C 2+ ) product evolution is a promising approach toward the sustainable production of value-added chemicals, yet remains challenging due to its low intrinsic activity. Here, we demonstrate the integration of bismuth oxide (BiO x ) and gold (Au) on titanium dioxide (TiO 2 ) substrate to achieve a high conversion rate, product selectivity, and catalytic durability toward photocatalytic OCM through rational catalytic site engineering. Mechanistic investigations reveal that the lattice oxygen in BiO x is effectively activated as the localized oxidant to promote methane dissociation, while Au governs the methyl transfer to avoid undesirable overoxidation and promote carbon─carbon coupling. The optimal Au/BiO x -TiO 2 hybrid delivers a conversion rate of 20.8 millimoles per gram per hour with C 2+ product selectivity high to 97% in the flow reactor. More specifically, the veritable participation of lattice oxygen during OCM is chemically looped by introduced dioxygen via the Mars-van Krevelen mechanism, endowing superior catalyst stability.

Photocatalytic CO 2 cycloaddition is a promising approach for CO 2 value-added processes. However, the efficiency of plasmon-assisted CO 2 cycloaddition still needs to be improved and the reaction mechanism is unclear. Herein, g-C 3 N 4 /Ag (ACN-Ag) hybrids exhibited superior activity of CO 2 cycloaddition by coupling a semiconductor into the plasmonic system, in which the ACN grafting amino group by the formation of carbon vacancies can enhance CO 2 chemisorption; meanwhile, photo-generated electrons from ACN transfer to Ag to form high-energy electrons, which can activate propylene oxide, accelerating the ring-opening step. Importantly, photo-generated electron injection from ACN to Ag and the interaction between Ag nanoparticles and ACN were confirmed by single-particle photoluminescence spectroscopy. The wavelength-dependent activity demonstrated that the plasmon excitation is crucial for the reaction. Moreover, in situ single-particle PL quenching caused by propylene oxide and in situ electron paramagnetic resonance verified the activation of propylene oxide by ACN-Ag. This work is conducive to an in-depth understanding of the mechanism of CO 2 cycloaddition at the single-particle level and provides guidance for the organic synthesis.

Background: Pericardial Effusion (PEf) can occur with Acute Heart Failure (AHF)., Objective: To evaluate the effect of PEf size on the prognosis of patients with AHF., Methods: According to the maximum size of PEf, all patients were divided into five groups. The primary outcome was in-hospital mortality. The independent effect of PEf size was determined by binary logistic regression analysis. The curve in line with the overall trend was drawn by local weighted regression (Lowess)., Results: We included 192 patients with AHF complicated by PEf. As PEf size increased, in-hospital mortality increased significantly (Group 5 vs. Group 1: 34.8 vs. 8.9% p=0.042). After adjusting for confounders, there was no significant association between PEf groups and in-hospital mortality (Group 5 vs. Group 1: odd ratio (OR), 95% confidence interval (CI): 2.72, 0.41-18.22, p=0.298). However, when PEf size was analysed as a continuous variable, an independent association between increased risk of inhospital mortality and PEf size was observed (OR, 95% CI: 1.08, 1.00-1.16, p=0.037). The Lowess curve showed a positive relationship between PEf size and in-hospital mortality. Furthermore, as PEf groups increased, the length of hospital stay (Group 5 vs. Group 1 median and interquartile range: 16, 14-21 vs. 13, 8-17 days, p<0.001) was significantly prolonged. An association between PEf size with acute kidney injury (AKI) was not observed., Conclusion: The PEf size was independently associated with the increased risk of in-hospital mortality in patients with AHF., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)
