Temporary plugging and diverting fracturing is an effective strategy to enhance fracture network complexity and expand the stimulated reservoir volume. However, in ultra-deep reservoirs, temporary plugging agents face a critical contradiction between maintaining high pressure-bearing capacity and achieving rapid deplugging under ultra-high temperatures, as dense structure is usually accompanied by slower degradation rate. And also, after deplugging, fractures tend to close under ultra-high in-situ stress, significantly reducing conductivity. Inspired by the stage-specific functionality and core utilization strategy of chia seeds, this study proposes an innovative, resource-efficient “soft shell–rigid core” plugging structure. A dense yet rapidly self-degradable soft shell, formed from high-temperature-resistant polymers and degradable crosslinkers, is employed to encapsulate a high-strength core to form a core–shell structure. This design balances high pressure resistance with rapid degradation, while providing sustained fracture support post-deplugging. The prepared Gel@CP undergoes a sequential process of “injection-plugging-degradation-fracture support.” It exhibits excellent fluid compatibility and suspension stability in the carrier fluid (static >3 h). Under 200 °C and 170,000 ppm salinity, the material reaches a maximum plugging pressure of 21.5 MPa, maintains 20 MPa for over 240 min, and shows a degradation rate above 99.9 % within 12 h, converting into environmentally benign water-soluble polymer fragments. After degradation, the exposed CP core effectively supports fractures, maintaining conductivity above 876 mD·cm under 70 MPa closure stress. This delicate biomimetic core–shell design endows this material with superior performance simultaneously in pressure bearing, fast degradation, and post-deplugging fracture support, which is reported for the first time, providing an innovative, sustainable, and practical solution for temporary plugging and propping under extreme reservoir conditions.

Polydopamine (PDA) interlayer enables ligand-bonded, electronically coupled interface for efficient charge transfer. • The photoanode displays 5.47 mA/cm 2 at 1.23 V RHE with 84.4% charge injection and 95.03% Faradaic efficiency, exhibiting excellent stability. • A triboelectric nanogenerator-electromagnetic generator (TENG-EMG) hybrid enables self-powered water oxidation under wind for off-grid H 2 production. Photoelectrochemical water oxidation is limited by sluggish interfacial charge transfer and fragile catalyst photoanode contacts. We introduce a polydopamine (PDA) interlayer that bridges NiFeOx and cobalt-doped bismuth vanadate (Co:BiVO 4 ), forming an intimate and ligand-bonded interface with strong electronic coupling. The bridge strengthens the interfacial electric field (IEF) strength, accelerates carrier separation and transfer, suppresses surface recombination, and stabilizes oxygen evolution intermediates, lowering kinetic barriers and external bias. First principles density functional theory with crystal orbital Hamilton population shows optimized adsorption at Fe sites and a reduced barrier at the rate-determining step, consistent with performance. Under air mass 1.5 global (AM 1.5 G) illumination, the optimized photoanode delivers 5.47 mA/cm 2 at 1.23 V versus reversible hydrogen electrode (vs. RHE) and 95.03% oxygen Faradaic efficiency with excellent stability. Because the electrode operates under low energy input, we demonstrate a closed-loop self-powered system in which a compact triboelectric and electromagnetic harvester, with wind-to-electricity conversion 49.5%, supplies sufficient power for continuous water splitting under ambient wind, achieving near stoichiometric gas evolution.

Specifically, the PDA bridge covalently links NiFeOx and Co-doped BiVO 4 , constructing a robust heterointerface with an enhanced interfacial electric field that accelerates charge separation, suppresses recombination, and stabilizes OER intermediates. Complementing this internal optimization, a compact hybrid wind harvester provides continuous, self-powered electron injection, enabling bias-free H 2 /O 2 co-evolution at near-stoichiometric ratios under wind conditions. This synergistic approach yielded a photoanode current density of 5.47 mA/cm 2 at 1.23 V (vs. RHE) with 95% Faradaic efficiency and exceptional long-term stability. By overcoming both interfacial fragility and external power dependence, this work offers a scalable, materials-agnostic blueprint for off-grid hydrogen production in resource-limited settings.

Male infertility is increasingly linked to impaired spermatogenesis, with emerging evidence implicating the umami taste receptor T1R1/T1R3 in male reproductive regulation. This study explored its role in regulating autophagy during spermatogenesis in Xiang pigs. Immunofluorescence confirmed T1R1/T1R3 co-localization in spermatogenic cells. Knockdown of TAS1R3 by RNAi triggered robust autophagy, characterized by increased autophagosomes, mitochondrial swelling, a significant accumulation of 2 C (diploid, spermatogonia) cells (increasing by ~21%), a corresponding reduction 4 C (tetraploid, spermatocytes) cells (decreasing by ~11%), a marked upregulation of Beclin 1 protein (by ~8.0-fold) and the LC3-II/LC3-I ratio (by ~2.9-fold), downregulation of mTOR , and suppression of key spermatogenic genes ( POU5F1 , SYCP3 , STRA8 ). Conversely, the receptors activation by its natural ligand L-glutamate (L-Glu) suppressed autophagy, reducing Beclin 1 levels and the LC3-II/LC3-I ratio to approximately 0.7-fold of the control. This activation improved cellular function, upregulated mTOR, increased 1 C (haploid, spermatids) cell populations, and downregulated STRA8 . Under H₂O₂-induced autophagy, L-Glu restored T1R3 expression, thereby reversing excessive autophagy and calcium overload, and rescuing the expression of autophagy-related ( BECN1 , mTOR ) and spermatogenesis-related genes ( SYCP3 , STRA8 ). In vivo experiments, dietary supplementation with 0.5% L-Glu significantly increased seminiferous tubule diameter and epithelium thickness in Xiang pig testes, upregulating T1R1 and the autophagy substrate p62/SQSTM1. In conclusion, T1R1/T1R3 regulates spermatogenesis by modulating autophagy. Activation by L-Glu mitigates autophagic damage and promotes spermatogenesis, offering a novel strategy for enhancing male fertility by targeting T1R1/T1R3.

Fossil solvent is replaced with edible vegetable oil in interfacial polymerization. • Soya-bean oil is optimal due to its well film-forming ability and low viscosity. • Soya-bean oil-based NF membrane exhibits thick PA layer with high salt rejection. • Soya-bean oil can act as green substitute for greener TFC membrane production. Despite the prevalent use as organic phase in interfacial polymerization (IP), conventional fossil solvents such as n-hexane are toxic, volatile and flammable, raising growing concerns about their safety. Regarding this issue, hereon we employ edible vegetable oils as a green organic phase to replace fossil solvents for the preparation of thin film composite (TFC) nanofiltration (NF) membranes. Five candidates including soya-bean oil, peanut oil, corn oil, flaxseed oil and olive oil were selected for exploration. Characterization demonstrates that soya-bean oil is the optimal selection, which can be attributed to its superior film-forming ability, low viscosity and facile removability. The selectivity of the soya-bean oil-based TFC NF membrane can be further improved by regulating IP parameters. Compared to the membranes fabricated with n-hexane and Isopar G, the soya-bean oil-based NF membrane exhibits a much thicker polyamide (PA) layer with thickness around 161 nm. This structural characteristic enables excellent desalination performance, with salt rejection exceeding 98% for MgSO 4 and 99% for Na 2 SO 4 . However, the increased thickness also results in a relatively lower water permeability of about 3.5 L m −2 h −1 bar −1 . Our study demonstrates the feasibility of using soya-bean oil as a substitute for conventional fossil solvents in IP reaction. It thereby offers a promising alternative for enabling greener production processes in TFC NF membrane manufacturing. Download: Download high-res image (180KB) Download: Download full-size image

Two-dimensional tin sulfide (SnS 2 ) shows great promise as a NO 2 gas-sensing material due to its large specific surface area and suitable band structure, yet its selectivity and detection limit remain inadequate. Herein, PdS/SnS 2 composite with PdS nanoparticle inlaid in lettuce-like structure SnS 2 was synthesized via a facile microwave-assisted method for room-temperature NO 2 detection. The optimized PdS/SnS 2 composite exhibits that the response value to 5 ppm NO 2 reached 2560% at room temperature under 50% relative humidity, which is approximately 10.7 times that of pristine SnS 2 (238%). Importantly, its experimental limit of detection (LOD) for NO 2 is as low as 800 ppt, while the theoretical LOD is below 164 ppt. Furthermore, it also shows outstanding reversibility and repeatability (RSD < 5%), and high selectivity (response ratio > 40) against interfering gases. The enhanced sensing performance is attributed to the synergistic effect of the PdS/SnS 2 heterojunction and sulfur vacancies, which promotes NO 2 gas adsorption on the material surface and electron transport inside the material. This study provides a feasible strategy for designing high-precision and ultra-trace NO 2 sensors with ppt-level detection capabilities at room temperature.

The coexistence of high-value pigment copper phthalocyanine (CuPc) and synthetic dyes in textile wastewater presents a dual challenge of environmental pollution and resource wastage. Herein, a novel singlet oxygen ( 1 O 2 )-dominated self-derived catalytic system was developed to simultaneously degrade rhodamine B (RhB) and recover valuable CuPc. Instead of requiring of the addition of external catalysts, wastewater-borne CuPc acted as an efficient heterogeneous activator for peroxymonosulfate (PMS). The system achieved 93.1% RhB removal within 30 min with an apparent rate constant of 0.089 min −1 , significantly outperforming the individual systems. Mechanistic studies combined with theoretical calculations revealed that the unique Cu-N 4 active sites facilitated PMS activation to generate 1 O 2 as the primary reactive oxygen species. This 1 O 2 -dominated pathway enabled the selective oxidation of electron-rich RhB while preserving the electron-deficient CuPc macrocycle, resulting in an over 80% recovery yield of CuPc. The system exhibited robust performance across a wide pH range (3.0-11.0) and in the presence of interfering anions. Moreover, the practical applicability of the system was further validated in simulated textile wastewater. This work provides a cost-effective, waste-derived catalytic strategy for complex textile wastewater treatment, promoting both pollution control and circular resource recovery.

The primary limitations of the oxygen evolution reaction (OER) electrocatalysts stem from poor electrical conductivity and insufficient accessibility of active sites. So highly productive catalysts are vital to lower the overpotential and enhance the kinetics of the sluggish OER. In this work, we present an effective OER electrocatalyst (NiS/N-CNT@Ni) and composites of Ni nanoparticles encapsulated in NiS/N-CNT fabricated via a simple two-step thermal treatment method. Meanwhile, due to the synergistic effect between NiS and nitrogen-doped carbon nanotubes (CNTs) and Ni, the NiS/N-CNT@Ni composites show higher OER electrocatalytic activity and better durability than commercial RuO 2 catalysts. Compared to commercial RuO 2 , the NiS/N-CNT@Ni catalyst demonstrates a lower overpotential (313 mV at 10 mA cm −2 ) and better stability. This study confirms that the NiS/N-CNT@Ni material not only exhibits a low overpotential but also presents a scalable, cost-effective synthesis strategy for high-performance composites applicable to energy conversion and storage.

In the clinical management of bacterial keratitis, antimicrobial delivery is limited by short ocular surface retention and low bioavailability. Meanwhile, free radical damage and severe inflammation caused by bacterial invasion remain key clinical challenges. To address these issues, we developed a novel metal-phenolic nanoparticles (FCTP), which were self-assembled from ferric ions (Fe 3 + ), curcumin, tannic acid, and ε-poly-L-lysine through metal-phenolic networks and electrostatic interactions, and were loaded onto a dissolvable microneedle (MN) system for the treatment of bacterial keratitis. In vitro assays demonstrated that the obtained FCTP nanoparticles exhibited a potent and rapid bactericidal activity by disrupting the bacterial biofilm. They can also scavenge excessive free radicals in the corneal cells. Moreover, FCTP nanoparticles regulated macrophage polarization from M1 to M2 by modulating phosphorylation of NF-κB pathway kinases, significantly inhibiting pro-inflammatory cytokines (IL-6, TNF-α) and upregulating anti-inflammatory IL-10. In Vivo experiments verified that FCTP-loaded dissolvable MNs penetrated the corneal barrier and biofilm. Compared with eye drops, the MN showed superior efficacy in eradicating bacteria, relieving ocular inflammation, and promoting corneal epithelialization with a single administration. Overall, this multifunctional nanoplatform provides a promising strategy for ocular diseases by targeting infection, oxidative stress, inflammation, and physiological barriers.

Nuclear energy has emerged as a vital clean energy source with super-high energy density. As a representative of fourth-generation nuclear reactors, High-Temperature Gas-Cooled Reactor (HTGR) generates substantial amounts of tetrahydrofurfuryl alcohol (THFA)-containing wastewater, for which effective treatment methods are rarely explored. Here, we present a selective and efficient approach employing anatase TiO2 as a photocatalyst to upcycle THFA into γ-hydroxybutyric acid (GHB), which can be used as a valuable bifunctional monomer to successful synthesize biodegradable poly(4-hydroxybutyrate). With optimized TiO2 catalyst, a THFA conversion of 87.6% and a GHB yield of 0.198 g/h/m2 were achieved. It was further elucidated that the •OH radicals generated by UV-excited TiO2 initiate the rapid transformation of THFA into GHB through two parallel pathways and the sluggish oxidation of GHB thereby facilitates its accumulation. The developed flow reactor could lead to the total conversion of THFA with GHB as main product that can be purified and separated, demonstrating the practical feasibility of the proposed strategy. This approach showcases the potential for converting THFA-containing wastewater into high-value chemicals through photocatalysis, offering an eco-friendly solution for THFA-containing wastewater treatment.

The practical application of high-energy-density potassium metal batteries (KMBs) is currently hindered by severe safety hazards derived from dendritic growth and the energy-diluting nature of electrochemically inactive components. Here we report a synergistic multi-functional strategy to construct an active separator (MoS 2 /PI), comprising a robust polyimide (PI) nanofiber skeleton and a kinetic-regulating MoS 2 coating. Corroborated by theoretical simulations and experimental characterizations, the potassiophilic MoS 2 layer effectively modulates the local electric field and minimizes the nucleation barrier, thereby orchestrating a uniform K + flux for dendrite-free deposition. Distinguishing this work from conventional inert barriers, the proposed design activates the separator into an energy-boosting component. Both the accessible carbonyl sites in the PI backbone and the MoS 2 coating participate in reversible potassiation. They contribute individual specific capacities of ∼7.0% and ∼21.2% relative to the KPB cathode, respectively, achieving a total capacity enhancement of ∼28.2%. Benefiting from this dual-active mechanism, the K||K symmetric cells exhibit ultra-stable cycling for over 4000 h. Potassium Prussian Blue (KPB)||K full cells equipped with the MoS 2 /PI separator deliver a superior capacity of 93.1 mAh g -1 , significantly outperforming those using commercial PP (69.3 mAh g -1 ) and GF (72.6 mAh g -1 ) separators. The device also demonstrates exceptional durability by maintaining 80.7% capacity after 1000 cycles, corresponding to a stable lifespan of 3270 h. This study validates the active separator strategy as a critical pathway for developing next-generation high-energy-density alkali metal batteries.

Achieving rapid demulsification of highly stable oil-in-water (O/W) emulsions with elevated water-to-oil ratios (＜100:1) at ambient temperatures poses a significant challenge in treating petroleum wastewater emulsions. Consequently, developing demulsifiers capable of lowering reaction temperatures, disrupting the oil-water phase equilibrium at high water-to-oil ratios, and exhibiting resistance to acids, alkalis, and salts is particularly crucial for addressing oil pollution issues in coastal regions. To address this objective, this study designed and synthesized a metal-organic framework crystal material-grafted hydroxypropyltrimethyl ammonium chloride chitosan (M-HACC) demulsifier, whose performance was subsequently evaluated. Results demonstrate that this demulsifier rapidly breaks high water-to-oil ratio (1000:1) emulsions at ambient temperature (30–35℃), achieving 99.0% demulsification efficiency within 30 min. For cationic CTAB-stabilized O/W emulsions, the efficiency reaches 99.0%. The demulsification efficiency of this demulsifier remains unaffected by acidic or alkaline conditions and high salinity. Within the pH range of 2–12, demulsification efficiency reaches 86.0 ± 4.0%, with optimal performance (99.0%) observed at pH = 7. Even at salinities ranging from 10 to 50 g/L, demulsification efficiency still achieves 95.0 ± 2.0%. Analysis of demulsification properties before and after grafting HACC indicates that M-HACC contains abundant oxygen-containing functional groups and positively charged moieties. At the oil-water interface, the emulsifying agent disrupts the interfacial film through hydrogen bonding and electrostatic attraction, ultimately achieving rapid demulsification and separation of highly stable O/W emulsions. The synthesized M-HACC demulsifier provides a rapid and effective solution to oil pollution in coastal waters.

The global spread of harmful algal blooms (HABs) has become a serious environmental problem, which urgently needs innovative control methods. This study explored the suppression efficiency of copper- and zinc-based metal-organic frameworks (MOFs) on growth and toxin production of the toxigenic microalga Alexandrium minutum . The physical characterization data confirmed that Cu-MOF has a higher surface area (1207 m 2 g −1 ) than Zn-MOF (56.9 m 2 g −1 ). Both materials could inhibit the growth of A. minutum with a concentration-dependent pattern. Comparatively, the Cu-MOF resulted in notable inhibition even at low concentrations. However, Zn-MOF stimulated growth at low concentrations but showed an inhibitory effect at higher doses (≥5 mg L −1 ). Both MOFs caused oxidative stress, alteration of cell membrane, and photosynthesis disruption. Additionally, transcriptomic findings revealed a major change of nutrient metabolism. Genes related to phosphorus uptake were mostly up-regulated, while those for nitrogen assimilation were largely down-regulated. The decrease in medium phosphorus and change in nitrogen levels also reflected this transcriptional response and demonstrated the imbalance in nutrient ratio. Furthermore, both MOFs, specifically at elevated concentrations, reduced overall production of paralytic shellfish toxins (GTX1, GTX4, GTX2 and GTX3). This study showed the potential utility of MOFs as targeted porous materials for HAB mitigation.
