A CdS-WO 3 S-scheme heterojunction material modified by CQDs was constructed through simple methods, which effectively increases the photocatalytic degradation rate of single CdS. In the composite material, CdS acts as a reducing photocatalyst (RP) and WO 3 acts as an oxidizing photocatalyst (OP), forming an S-scheme heterojunction. In order to solve the photocorrosion problem of CdS, carbon quantum dots (CQDs) were loaded onto CdS. The CQDs possess a high work function, enabling them to facilitate electron transfer, enhance the migration of photogenerated carriers, and suppress electron-hole pair recombination, thus improving photocatalytic performance. The characterizations of XRD, TEM, element mapping, and XPS confirmed the successful synthesis of the CQDs-CdS-WO 3 composite. The material not only exhibited a photocatalytic degradation efficiency of 89.7% and 58.8% towards norfloxacin and tetracycline, respectively, but also revealed a certain degradation capability toward methylene blue and methyl orange. The primary active substances relevant in this degradation process are h + , 1 O 2 , H 2 O 2 , • O 2 − , and • OH. After multiple cyclic experiments, the material still maintains stable crystalline structure and degradation activity. Therefore, the successful preparation of this composite material provides a new method for photocatalytic decomposition of antibiotics and organic dyes.

Coating the charged aromatic polymers on ultrafiltration membranes is a feasible strategy to fabricate antifouling nanofiltration (NF) membranes. However, these NF membranes haven’t achieved high rejection and also are very limited because such polymers should be soluble in commonly polar solvents. Sulfonated poly(arylene ether ketone)s (sPAEKs) generally show poor solubility in commonly polar solvents due to their rigid polymer backbones, thus they could not be employed as the coating materials of NF membranes at present. Herein, the soluble sPAEKs in commonly polar solvents are synthesized by attaching methyl side groups to their polymer backbones. Accordingly, these sPAEKs could be coated on ultrafiltration membranes to prepare the antifouling NF membranes. Moreover, the Lewis acid-base interactions between the carbonyl and cation of the sPAEKs coating layer could improve rejection. Besides, their hydrophilic sPAEKs coating layer is favorable for improving permeability. Therefore, the sPAEKs coating layer endows the as-made membrane with excellent nanofiltration performances, such as an antibiotic rejection of 98%, a flux of 31.8 LMH/bar, an antibiotic/NaCl selectivity of 43.6, and a flux recovery rate of 98% for the foulant of bovine serum albumin. It still showed excellent resistance to chlorine oxidation because of the aromatic backbone of the sPAEKs coating layer. This fabrication strategy paves a facile way to achieve high performance NF membranes.

Heterogeneous catalysis promises to accelerate sulfur-involved conversion reactions in lithium-sulfur batteries. Solid-state Li2S dissociation remains as the rate-limiting step because of the weakly matched solid-solid electrocatalysis interfaces. We propose an electrochemically molecular-imprinting strategy to have a metal sulfide (MS) catalyst with imprinted defects in positions from which the pre-implanted Li2S has been electrochemically removed. Such tailor-made defects enable the catalyst to bind exclusively to Li atoms in Li2S reactant and elongate the Li–S bond, thus decreasing the reaction energy barrier during charging. The imprinted Ni3S2 catalyst shows the best activity due to the highest defect concentration among the MS catalysts examined. The Li2S oxidation potential is substantially reduced to 2.34 V from 2.96 V for the counterpart free of imprinted vacancies, and an Ah-level pouch cell is realized with excellent cycling performance. With a lean electrolyte/sulfur ratio of 1.80 μL mgS–1, the cell achieves a benchmarkedly high energy density beyond 500 Wh kg–1.

Anion exchange membranes (AEMs) are central to clean-energy electrochemical technologies, yet achieving high hydroxide conductivity together with dimensional and alkaline stability remains challenging. Here we implement a straightforward branching strategy in poly(arylene 3-piperidinium)s by incorporating two trifunctional units, i.e., triptycene and 1,3,5-triphenylbenzene, into the polymer backbone. This architecture suppresses water uptake and swelling without compromising the membrane's ion-transport efficiency and chemical durability. Compared to linear membranes, the branched membranes exhibit a 34−36% reduction in water absorption. Triptycene-based branched AEMs achieved superior performance, including suppressed swelling (<18% at 80 °C), high conductivity up to 191 mS cm −1 at 80 °C, and improved alkaline stability, remaining intact in 1 M NaOH for at least 2000 h. Importantly, a water electrolyzer based on B-PT3Pip-3%Trip demonstrated a current density of 6.9 A cm −2 at 2.0 V and 80 °C, and can operate stably under 1 A cm −2 at 60 °C for 1000 h with a voltage decay of only 81 μV h −1 . The synthetic simplicity of the branching strategy, together with the combination of suppressed swelling, high conductivity, and long-term durability, makes branched poly(arylene 3-piperidinium) AEMs highly promising for AEM water electrolysis applications.

S-modified MnO 2 /Ni(OH) 2 hollow nanosheets were constructed for enhanced UOR. • Requires 1.30 V at 10 mA cm −2 and remains stable for 48 h. • MnO 2 phase transformation promotes the generation of Ni 3+ active species. • S-modification enhances urea adsorption while suppressing competitive OH − adsorption. The urea oxidation reaction (UOR) provides an alternative anodic process for electrochemical hydrogen generation, but developing catalysts with high activity and sustained performance remains challenging. In this study, we report an S-modified nickel-based catalyst with a hollow nanosheet architecture (α/γ-MnO 2 /Ni(OH) 2 -S), demonstrating enhanced UOR performance in alkaline media. α/γ-MnO 2 /Ni(OH) 2 -S attains a current density of 10 mA cm −2 at a potential of 1.30 V and maintains reliable durability for 48 h without significant degradation. The improved activity and durability are associated with the hollow nanosheet structure, the phase transformation of MnO 2 , and S-modification, which facilitate mass transport and charge transfer, modulate the electronic structure of Ni(OH) 2 to promote the formation of Ni 3+ active species, and enhance the electrochemical response to urea at different concentrations. This research establishes a practical avenue for constructing advanced nickel-based UOR catalysts through rational structural optimization, phase regulation, and surface modification.

Bisphenol S (BPS), as an environmental pollutant, poses a potential threat to reproductive system health. In this study, we added BPS to primary human endometrial stromal cells (hEnSCs) to detect the acute injury it causes and its long-term effects on the endometrium. The results showed that short-term treatment with BPS can significantly promote oxidative stress and apoptosis of hEnSCs, while long-term treatment can cause excessive senescence of hEnSCs and reduced receptivity. In addition, the culture medium of senescent cells treated with BPS can induce senescence of young hEnSCs. Studies have reported that secondary senescence can be alleviated, and we utilised the autophagy activator Rapa to treat secondary senescence of hEnSCs. We found that Rapa can inhibit the senescence of young cells induced by the culture medium of senescent cells treated with BPS. Therefore, autophagy activated by Rapa can attenuate the secondary senescence of hEnSCs induced by BPS-treated culture medium.

Aqueous Zn─S batteries are promising energy storage systems with high theoretical capacity and low cost. However, the direct conversion between S and ZnS at the cathode suffers extremely sluggish reaction kinetics, which further decay rapidly upon the increase of current density and active material loading. Facing these challenges, we herein present a bi-directional redox mediator strategy and identify a self-adjusted Cu-based candidate. It possesses two redox couples whose potentials are on either side of the thermodynamic redox potential of S/ZnS reaction while between its kinetic oxidation and reduction potentials. These alignments enable the bi-directional mediator to catalyze the charge and discharge processes using either redox couple, respectively. As a result, the sulfur cathode reaches a high capacity of 1629 mAh g −1 at 0.1 A g −1 . It also maintains 880 mAh g −1 after 500 cycles at 1 A g −1 , superior to rapid decay to 148 mAh g −1 after only 28 cycles with the mediator free cathode. Furthermore, with a high sulfur loading of 7.3 mg cm −2 and lean electrolyte of 7 µL mg S −1 , the Zn─S battery achieves a high areal capacity over 10 mAh cm −2 .

Two types of poly(ionic liquids) (PILs), namely linear PILs (LPILs) and reticulated cross-linked network PILs (RPILs), were synthesized and evaluated for the adsorption of gold thiosulfate complex ([Au(S 2 O 3 ) 2 ] 3− ) from thiosulfate solutions. Experimental results showed that the adsorption of [Au(S 2 O 3 ) 2 ] 3− on the PILs followed the pseudo-second-order kinetic model, indicating that the adsorption process was dominated by chemical adsorption. In terms of adsorption thermodynamics, the bromide-based LPIL fitted the Hill adsorption model, whereas the other PILs followed to the Freundlich model. The main interactions between the PILs and [Au(S 2 O 3 ) 2 ] 3− were electrostatic attraction and anion – π interactions, and ion exchange dominated the gold adsorption process. The RPILs exhibited higher gold adsorption capacities than the LPILs. However, gold desorption was more readily achieved with LPILs, primarily owing to their weaker affinity for gold species. In addition, the perchlorate-based LPIL showed good adsorption selectivity and recyclability toward [Au(S 2 O 3 ) 2 ] 3− . This study provides a promising strategy for the efficient separation and recovery of gold from thiosulfate media.

PEDV infection induces intracellular iron accumulation in host cells. • Iron promotes CoV replication by enhancing Fe-S cluster-dependent RdRp activity. • TEMPOL suppresses CoV replication by disrupting viral Fe-S cluster integrity. • TEMPOL exhibits broad-spectrum anti-CoV activity in vitro and in vivo. • TEMPOL effectively counteracts iron-exacerbated viral pathogenesis in vivo. Coronaviruses (CoVs) can cause severe respiratory and enteric diseases, posing major threats to human health and the livestock industry. However, the host metabolic mechanisms underlying viral replication remain unclear. Using porcine epidemic diarrhea virus (PEDV) as the primary model, this study investigated the role of iron metabolism in CoV replication and its mechanisms. Our results showed that PEDV infection markedly induced intracellular iron accumulation, while exogenous iron supplementation enhanced viral replication and iron chelation suppressed it. Mechanistically, iron enhances viral replication by promoting the formation of iron-sulfur (Fe-S) clusters, essential cofactors for the viral RNA-dependent RNA polymerase (RdRp). Based on these findings, we further evaluated the antiviral activity of TEMPOL, a small molecule targeting viral Fe-S clusters. TEMPOL reduced RdRp activity and effectively inhibited PEDV replication. Moreover, TEMPOL exhibited broad-spectrum antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), infectious bronchitis virus (IBV), and porcine deltacoronavirus (PDCoV). Importantly, TEMPOL effectively reversed FAC-promoted viral pathogenesis, alleviating tissue lesions and clinical symptoms across multiple CoV animal models. Collectively, this study reveals a key role of iron metabolism in CoV replication and suggests that targeting viral Fe-S clusters may provide a novel strategy for anti-CoV therapy against diverse CoVs.

Hydrogen production via photocatalytic water splitting holds great promise for efficient solar energy conversion. While ZnIn₂S₄ (ZIS) exhibits a suitable band structure for visible-light-driven hydrogen production, its practical application is significantly limited by low charge separation efficiency and poor stability. This work pioneers an acousto-hydrothermal strategy utilizing high-frequency ultrasonic atomization to synthesis structurally optimized ZIS. Systematic characterization reveals that ultrasonic cavitation compresses crystal lattices to enhance Zn 3d-S 3p orbital hybridization, assembles nanosheets with a 20 % increased surface area, leading to enhanced charge separation efficiency. The optimized ZIS demonstrates significantly enhanced photocatalytic activity and stability. It achieves a remarkable hydrogen evolution rate of 51.8 mmol g⁻¹ h⁻¹ under 455 nm visible light irradiation, representing an 86 % improvement over pristine ZIS. After a 15 h reaction, the catalytic system produces 8.3 mmol of H₂ (185.9 mL at standard conditions). This work presents an innovative strategy for designing nanosheet-based materials to achieve high-efficiency photocatalytic hydrogen evolution.

In this work, an agarose-polyacrylamide hydrogel electrolyte (APE) with an interpenetrating and hierarchically porous network is introduced to reconstruct solvation and interface dynamics for a high-performance Zn-S batteries. This structure results in a high ionic conductivity of 42.1 mS cm −1 and a Zn 2+ transference number of 0.64. Molecular dynamics reveal that most H 2 O and SO 4 2− are excluded from the outer Helmholtz plane, forming an optimized electric double layer on Zn surface. Consequently, a prolonged 1200 h Zn plating/stripping behavior is obtained with 1 mAh cm −2 at 1 mA cm −2 , and a high Zn plating of 20 mAh cm −2 at 5 mA cm −2 . Furthermore, APE modulates the nucleation mode of ZnS, converting the originally sluggish and non-uniform progressive nucleation into a rapid and uniform instantaneous nucleation. As a result, this hydrogel Zn-S batteries deliver a capacity of 895 mAh g −1 and 91% capacity retention within 300 cycles at 5 A g −1 .

The accelerating demand for sustainable, high-rate, and durable energy storage underscores the need for carbon electrodes that simultaneously offer balanced micro–mesoporosity for rapid ion transport and robust heteroatom functionalities for enhanced interfacial chemistry. In the present work, we convert bitumen asphaltenes and recycled cellulose acetate into N/S co-doped hierarchical carbons via ammonium persulfate-assisted co‑carbonization and KOH activation. The optimized carbon combines an ultrahigh specific surface area of 3527 m 2 g −1 , balanced micro–mesoporosity, and uniformly distributed electroactive N/S species (pyridinic/pyrrolic N, C S, SO x ), enhancing conductivity and pseudocapacitance. In three-electrode tests, the electrode delivered 382.5 F g −1 at 0.5 A g −1 with 74% retention at 10 A g −1 . The symmetric aqueous device achieved a specific capacitance of 288.2 F g −1 at 0.5 A g −1 , energy densities of 10.01 Wh kg −1 at 257.4 W kg −1 and 5.42 Wh kg −1 at 6728.3 W kg −1 , and 108.7% capacitance retention after 10,000 cycles at 5 A g −1 . This study advances sustainable energy storage by enabling low-cost, high-performance supercapacitors and promoting solid-waste recycling.
