Vacancy-ordered double perovskites have emerged as promising candidates for single-component white light-emitting diodes (WLEDs) owing to their intrinsic broadband emission, dopant-induced color tunability, and stable optoelectronic properties. However, their practical application is limited by the difficulty of obtaining high-quality crystals, as the typically rapid and poorly controlled crystallization processes tend to induce lattice disorder and defect formation. In this work, we report a 4-mercaptobenzoic acid (4MBA)-assisted coprecipitation strategy to synthesize high-quality 3%Sb 3+ -doped Cs 2 ZrCl 6 (CZC:3%Sb (4MBA)) microcrystals (MCs). Despite its non-coordinating nature with the crystal surface, 4MBA functions as an effective kinetic regulator that retards crystallization and enhances growth control, thereby suppressing lattice disorder and defect formation to improve crystal quality. As a result, the optimized CZC:3%Sb (4MBA) MCs achieve a photoluminescence quantum yield (PLQY) of 88%, twice that of the unmodified MCs, while concurrently ensuring excellent ambient and thermal stability. Fabricated WLEDs based on CZC:3%Sb (4MBA) MCs exhibit warm white emission with a high color rendering index (CRI) of 94 and maintain stable operation over 14 h. This work presents an effective strategy for regulating crystal growth to enhance the optical performance of lead-free vacancy-ordered double perovskites, paving the way for high-performance, single-component WLEDs.

Agarwood is a resinous heartwood valued as both a fragrance and a medicinal resource. Here, agarwood samples from four major producing regions (Hainan, China; Vietnam; Indonesia; and Malaysia) were systematically compared using headspace solid-phase microextraction coupled with comprehensive two-dimensional gas chromatography–time-of-flight mass spectrometry (HS-SPME–GC×GC–TOFMS). Tentative identifications were assigned against NIST 2020 with retention indices (RI) calculated from a C7-C30 n-alkane series. After de-duplication across 12 samples, 1990 non-redundant volatile features were obtained. Hydrocarbons (22.0–36.1%) and alcohols (6.5–15.0%) predominated, followed by aldehydes, ketones and esters. Principal component analysis and OPLS-DA achieved clear origin-based discrimination. Relative odor activity value (ROAV) analysis highlighted vanillin, ( E )-2-nonenal, heptanal, 2-undecanone, 2,3-butanedione and 2-ethylhexanol (ROAV ≥ 1) as key aroma-impact volatiles underpinning sweet, fruity and woody notes. These results establish a volatile–aroma linkage for agarwood and provide a chemical basis for origin authentication, industrial quality grading, and standardization of agarwood-derived ingredients.

Mini/Micro-LED backlight systems require color conversion layers that combine submicron size with high absorption efficiency. However, commercial phosphors are difficult to meet this demand due to their relatively large particle size. The Cs 2 MnF 6 system demonstrates a unique advantage due to its intrinsic high absorption efficiency. In this study, submicron-sized Cs 2 MnF 6 was successfully prepared via anti-solvent synthesis method. Furthermore, a Si 4+ reverse doping strategy was employed (Cs 2 MnF 6 :Si 4+ ) to effectively suppress concentration quenching. At the optimal doping concentration, the emission intensity reaches 3523 times that of the undoped Cs 2 MnF 6 host. Subsequently, surface passivation treatment was applied with a Mn 4+ -free Cs 2 SiF 6 coating. This treatment not only suppressed surface quenching, further increasing the luminescence intensity, but also significantly improved the material's moisture resistance. The finally obtained Cs 2 MnF 6 :Si 4+ @Cs 2 SiF 6 phosphor has an average particle size of approximately 800-900 nm and a high absorption efficiency of 48.4%. Its luminescence intensity is 4.25 times that of the un-passivated sample. And this material retained 75% of its initial luminescence intensity after 240 minutes of immersion in deionized water. In contrast, the untreated sample remained only 16.4%. These advancements highlight the significant potential of this material in mini/micro-LED backlight systems, offering new possibilities for the development of next-generation display technologies.

As a bridge between innate sensing and adaptive immunity, the functional state of dendritic cells (DCs) is a critical determinant of protective immune responses. Inflammasome activation can induce a “hyperactive” state characterized by highly activated DCs with preserved viability, enhanced antigen presentation, migration capacity, and IL-1β secretion, representing an ideal condition for eliciting robust cytotoxic T lymphocyte (CTL) responses. However, attempts to apply this state in cancer vaccines face constraints including safety concerns, formulation complexity, and limited control over stimulation strength. Here, we develop a lipid nanoparticle (LNP) platform that combines plasmid DNA (pDNA) with fatty acids to optimize the inflammasome activity and direct DCs toward hyperactivation. Following the establishment and screening of the fatty acid-incorporated plasmid lipid nanoparticle (FA-pLNP) library, a palmitic acid formulation designated PA15 is identified as the lead candidate to induce DC hyperactivation. Mechanistic studies reveal that pDNA provides nuclear factor kappa B (NF-κB)-mediated priming, while palmitic acid promotes NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome assembly, enabling effective interleukin-1β (IL-1β) release and subsequent immune activation. Therapeutic vaccination with PA15 demonstrated significant antitumor efficacy in mouse tumor models. Collectively, this work provides a practical strategy for inducing hyperactive DCs and establishes a general design principle for next-generation cancer vaccines.

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. Download: Download high-res image (295KB) Download: Download full-size image To address fossil fuel-driven environmental challenges, we developed a dual-strategy synergy for solar-driven water oxidation: external electron injection via a hybrid nanogenerator and internal interfacial engineering via a polydopamine (PDA) molecular bridge. 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.
