To address the limited activity and durability of oxygen evolution reaction (OER) electrocatalysts, we present an integrated in situ strategy for constructing a three-dimensional Ni-Co dendritic electrode matrix coupled with a surface amorphous Ni-Co-Fe layered double hydroxide (LDH) catalytic layer. A Ni-Co dendritic matrix (NCDEM) with enhanced electrolyte accessibility and mass transport properties is first fabricated via jet electrodeposition, followed by the in situ hydrothermal growth of Ni-Co-Fe LDH nanosheets to construct a Ni-Co-Fe dendritic electrode (NCFDE). The introduction of NaBO₂ during the hydrothermal process regulates surface etching kinetics and the Fe³ ⁺ coordination environment, promoting uniform nanosheet growth and triggering the crystalline-to-amorphous transition of the LDH structure. The amorphous LDH layer increases the accessible active surface area, facilitates the formation of reconstructed NiOOH active species during OER, and enhances structural stability during prolonged electrochemical operation. The optimized B2-NCFDE exhibits outstanding OER performance in 1 M KOH, requiring an overpotential of only 215.34 mV to achieve 100 mA cm⁻², with a Tafel slope of 38.29 mV dec⁻¹ and stable operation at 500 mA cm⁻² for 2000 h. Furthermore, the B2-NCFDE||B2-NCFDE electrolyzer achieves 100 mA cm⁻² at a cell voltage of 1.822 V and demonstrates excellent durability for overall water splitting. This work provides a scalable strategy that integrates electrode architecture engineering with amorphous LDH regulation for efficient and durable hydrogen production.

Biochar (BC)-mediated aerobic oxidation of arsenite (As(III)) has been reported, but the coupling among phenol-quinone redox cycling, O 2 activation, and pH-regulated H 2 O 2 formation remains insufficiently resolved. In this study, pine-sawdust-derived BC and molecular analogues of phenolic/quinoid moieties, hydroquinone (HQ) and 1,4-benzoquinone (BQ), were used to examine As(III) oxidation at pH 3.0, 7.0, and 9.5 under oxic and oxygen (O 2 )-limited conditions. Under oxic conditions, BC oxidized 42.4%, 21.6%, and 74.7% of As(III) after 24 h at pH 3.0, 7.0, and 9.5, respectively, whereas arsenate (As(V)) formation was negligible under O 2 -limited conditions. BC generated hydrogen peroxide (H 2 O 2 ) in air-equilibrated suspensions, with maximum concentrations of 88.5, 38.8, and 204.2 μM at pH 3.0, 7.0, and 9.5, respectively·H 2 O 2 -associated pathways contributed an estimated 69.2%, 77.2%, and 67.4% to As(III) oxidation at pH 3.0, 7.0, and 9.5, respectively. Superoxide dismutase suppressed O 2 •- generation without affecting H 2 O 2 accumulation or As(III) oxidation, indicating that O 2 •- primarily served as an intermediate in H 2 O 2 formation. Tert-butanol negligibly altered As(V) formation, consistent with the absence of detectable •OH. The BQ/HQ model system confirmed the chemical feasibility of quinone reduction, HQ re-oxidation by O 2 , and associated H 2 O 2 generation, but it should be interpreted as a molecular analogue rather than direct proof of the heterogeneous BC surface mechanism. Overall, BC mediates As(III) oxidation mainly via O 2 -dependent H 2 O 2 production promoted by phenol-quinone-like redox cycling, while the non-monotonic pH trend (pH 9.5 > pH 3.0 > pH 7.0) reflecting the combined effects of As(III) speciation, surface redox behavior, and H 2 O 2 availability.

In-situ preparing robust CoFe 2 O 4 /PCN PMS activator for multi-pollutant degradation. • Complete degradation TC within 3 min with the rate constant 24-fold higher than CN • Degradation intermediates, routes and toxicity were explored • Wide light absorption, exposed active sites, and charge behavior boost photocatalysis Facing the urgent environmental crisis, it is imperative to create an efficient and robust technology for treating diverse pollutants in aquatic environments. Herein, a CoFe 2 O 4 /PCN composite was designed via a facile in-situ growth method, in which CoFe 2 O 4 uniformly grows on carbon nitride. This architecture not only forms a close interface that facilitates efficient charge separation and migration, but also introduces abundant mixed-valence metal sites, that serve as superior active centers for peroxymonosulfate (PMS) activation and subsequent organic pollutant removal. Specifically, under visible light, the optimized catalyst can 100% degrade TC within 3 min (complete degrade rhodamine B within 20 s, methyl orange within 40 s, and methylene blue within 3 min), and the rate constant was 24-fold higher than pristine CN, surpassing most reported catalysts. The catalyst also demonstrates excellent recyclability and broad pH adaptability. The mechanism behind the performance enhancement stems from the significantly broadened light absorption (supported by UV–vis DRS), fully exposed active sites (evidenced by SEM/TEM/AFM and N₂ adsorption), and enhanced charge behaviors (supported by PCR, EIS, PL/TRPL and KPFM), especially caused by strong internal electric field. At last, the active species, degradation intermediates and their toxicity were investigated using TC degradation as a model, coupled with DFT theoretical calculations. This work proposes a rational design strategy toward constructing efficient and robust photocatalysts, revealing significant promise for water remediation.

Upconversion luminescent materials can convert near-infrared excitation into higher-energy emissions, showing great potential in applications such as temperature sensing and optical anti-counterfeiting. However, it remains challenging to simultaneously achieve high thermal stability, sensitive temperature response, and circularly polarized luminescence within a single system. In this work, chiral Bi 4 O 5 Br 2 : Yb 3+ /Er 3+ nanosheets were synthesized via a hydrothermal method combined with chiral modification and pH regulation, and their structural and luminescent properties were systematically investigated. The results indicate that pH regulation during precursor synthesis facilitates the optimization of the Bi 4 O 5 Br 2 morphology and improves its crystallinity, thereby promoting a more ordered crystal growth process. Subsequently, chiral induction introduces local lattice distortion while suppressing defect formation. The synergistic effect of both helps to significantly enhance upconversion luminescence performance. Under variable-temperature conditions, the 849 nm near-infrared emission ( 4 I 9/2 - 4 I 15/2 ) exhibits negligible thermal quenching over the temperature range of 293−533 K, in sharp contrast to the thermally quenched behavior of visible emissions. Based on this feature, a fluorescence intensity ratio (FIR) thermometry strategy was established, achieving high sensitivity with an absolute sensitivity ( S a ) of 20.73%/K and a relative sensitivity ( S r ) of 3.45%/K. Furthermore, the material exhibits pronounced emission intensity differences under circularly polarized excitation and detection. This enables the construction of a polarization-color synergistically tunable luminescent anti-counterfeiting system. This work provides a new strategy for designing multifunctional upconversion materials that integrate optical thermometry and polarization-based anti-counterfeiting capabilities.

Fe 2 O 3 /g-C 3 N 4 accelerates Fe redox cycling for efficient H 2 O 2 activation. • g-C 3 N 4 pumps electrons to Fe sites, boosting interfacial charge transfer. • Alkaline microenvironment uniquely steers ROS pathway toward O 2 •− generation. • Process yields 93.2% NO x removal, converting NO into valuable N-resources. To overcome the challenges associated with low-temperature industrial flue gas denitrification, this study presents a highly efficient Fe 2 O 3 /g-C 3 N 4 heterogeneous Fenton catalyst synthesized via a facile impregnation approach. This composite effectively activates H 2 O 2 for deep NO x elimination. Under optimal alkaline conditions, the Fe 2 O 3 /g-C 3 N 4 system achieved a remarkable maximum NO x removal efficiency of 93.2%, while demonstrating exceptional durability by retaining over 80% efficiency across five consecutive reaction cycles. Comprehensive experimental characterization coupled with density functional theory (DFT) calculations reveal that g-C 3 N 4 serves as an electron-rich reservoir. This framework systematically accelerates the rate-limiting Fe 2+ /Fe 3+ redox cycling on the Fe 2 O 3 surface through enhanced interfacial charge transfer. Crucially, the alkaline environment uniquely steers the reactive oxygen species (ROS) evolution pathway toward the highly selective generation of superoxide radicals (O 2 •− ). These predominant O 2 •− species rapidly oxidized NO to form peroxynitrite intermediates, thereby promoting the deep conversion of NO into recoverable nitrate and nitrite products. This work provides a robust and scalable strategy for low-temperature NO ₓ purification and offers new mechanistic insights into how the reaction microenvironment regulates radical selectivity.

Gastric cancer is a highly prevalent malignant tumor of the digestive system worldwide. Although andrographolide (AG) and coixol (CX) possess potential anti-gastric cancer effects, their clinical application is restricted by low bioavailability and poor targeting ability. Based on the meridian tropism theory of traditional Chinese medicine and the concept of “integrated drug and carrier”, this study constructed Bletilla striata polysaccharide-vitamin E succinate (BSP-VES) polymeric micelles co-loaded with AG and CX (AG&CX@BSP-VES) for synergistic targeted therapy of gastric cancer. In this study, AG&CX@BSP-VES was first systematically characterized in vitro to clarify its physicochemical properties, drug release behavior and hemolysis profile. Subsequently, using subcutaneous and orthotopic gastric cancer mouse models as research objects, in vitro cellular uptake and in vivo tumor targeting ability efficacy and biological safety of this drug delivery system were further evaluated. Results showed that the micelles were regularly spherical with a particle size of approximately 105 nm, exhibited favorable biological safety and asynchronous differential release characteristics, and could be specifically internalized by cells in vitro (which could be blocked by free BSP). In vivo, the accumulation of micelles in tumor masses was significantly higher than that in normal gastric tissues. Moreover, the cytotoxicity of the micelles against SGC-7901 tumor cells was remarkably higher than that of free AG or CX alone, which was attributed to enhanced cellular drug uptake and the synergistic effect between AG and CX. This study provides novel insights for the precise delivery of active ingredients from traditional Chinese medicine and individualized therapy of gastric cancer.

Cold plasma achieved dual pesticide reduction and quality modulation in cinnamon. • Structural modification promoted the release of aroma-related volatile compounds. • Volatilomics identified key markers for CP-induced aroma quality changes. • Untargeted metabolomics revealed carbohydrate-associated metabolite changes. • CP improved antioxidant capacity while preserving antibacterial functionality. To evaluate Cold plasma (CP) for pesticide residue control in spices, dried Cinnamomum cassia Presl bark pieces fortified with eight pesticides were used as a controlled postharvest model. Volatilomics and untargeted metabolomics were further used to explore the related quality-modulation mechanisms. CP promoted pesticide degradation, with higher removal efficiencies obtained at increased power and treatment time. The mean degradation percentages generally showed an upward trend with increasing plasma power and treatment time. Among the conditions examined, treatment at 1.3 kW for 10 min produced the highest mean degradation percentage for each of the eight pesticides, with values ranging from approximately 15% to 55% in fortified cinnamon bark. CP also altered the surface structure and water status of cinnamon, as indicated by stronger surface etching, reduced contact angle, and decreased bound water content. Volatilomic analysis identified 111 volatile organic compounds, mainly terpenoids. CP increased the detectable abundance of key flavor- and function-related compounds, including d -limonene, cinnamyl acetate, β-elemene, and α−/β−pinene, and 30 volatile markers were screened. Untargeted metabolomics identified 164 metabolites and 52 differential metabolites, which were mainly annotated to carbohydrate-related pathways. Meanwhile, DPPH radical-scavenging and FRAP reducing capacities were higher after CP treatment, whereas antibacterial properties remained generally stable. These results indicate that CP can reduce pesticide residues in cinnamon while improving volatile flavor release and maintaining functional quality, providing a basis for its application in green processing of spices and plant-derived foods.

Silybin is a clinically validated adjunct for liver disorders, yet poor absorption and rapid metabolism curtail its wider therapeutic use. Exploiting the distinctive hepatic distribution of glycyrrhetinic acid (GA) receptors, we augmented silybin B (SilB, an isomer of silybin) delivery by encapsulating it within GA-modified liposomes. We constructed a response-surface model to optimize liposome fabrication, identifying the optimal recipe: 5.89:1 lecithin/cholesterol, 100:2.13 lecithin/DSPE-PEG2000, and 12:5.05 lecithin/SilB. DSPE-PEG2000-GA was generated through amidation and substituted for DSPE-PEG2000 to yield GA-modified SilB liposomes (GSL). GSL exhibited 49.34 ± 0.25% encapsulation efficiency, 9.13 ± 0.04% drug loading, 148.881 ± 4.786 nm diameter, 0.269 ± 0.024 polydispersity index, and −23.433 ± 0.775 mV zeta potential. GSL remained stable for 7 days and sustained drug release for 24 h in PBS. GA-modified liposomes displayed accelerated HepG2 uptake and heightened murine hepatic retention, underpinning its superior therapeutic performance. GSL engaged non-alcoholic fatty liver disease on multiple aspects, suppressing lipid accretion, inflammation, and insulin resistance, and significantly surpassed free SilB in therapeutic magnitude.

The development of the high catalytic performance zinc-based catalyst featuring eco-friendly remains a considerable challenge in environmental treatment. Serving as a nitrogen-rich anchoring ligand, 3,5-diamino-1,2,4-triazole was adopted to construct a porous Zn-based catalyst through a facile grinding-assisted pyrolysis route. Zinc species served as both a pore-forming agent and active site, endowing the ZnNC with a zinc loading of 11.26 wt% with a specific surface area of 388.29 m 2 /g. The as-prepared ZnNC displayed outstanding performance in activating peroxymonosulfate (PMS), enabling complete degradation of the refractory contaminant carbamazepine (CBZ) within 15 min, and the apparent rate constant (k obs ) was 0.395 min⁻¹, surpassing the performance of most reported metal-based catalysts. Interestingly, the reaction at 0 °C was more favorable for the degradation of CBZ, which was attributed to the strengthened adsorption of CBZ on the ZnNC at low temperatures, differing from most previous reports that the degradation rate increased with rising temperature. Quenching experiments in combination with EPR characterizations revealed that 1 O 2 acted as the predominant reactive oxygen species (ROS) in the ZnNC/PMS system, endowing the catalytic system with wide pH adaptability and strong anti-interference capability against coexisting ions. Importantly, ZnNC maintained a relatively stable CBZ removal rate after five cycles and during 24 h of continuous operation, demonstrating its preliminary application potential. This work provides a viable and facile strategy for the rational construction of highly active and stable zinc-based catalysts for wastewater remediation.

ESCC samples show higher USP44 succinylation and lower expression vs adjacent non-tumor tissues. • CPT1A binds USP44 and specifically mediates its K543 succinylation, reducing USP44 stability. • K543 succinylation triggers USP44's ubiquitination-mediated degradation in ESCC tissues. • USP44 stabilizes CDK5RAP3 by K166 deubiquitylation, dependent on its catalytic C282 residue. • USP44 inhibits ESCC xenograft growth, lung and lymphatic metastasis by stabilizing CDK5RAP3. Ubiquitin-specific proteases (USPs) function in multiple types of tumor progression by controlling protein turnover. However, the regulatory mechanism of ubiquitin carboxyl-terminal hydrolase 44 (USP44) in esophageal squamous cell carcinoma (ESCC) remains incompletely understood. Here, we show that USP44 expression correlates with tumor size, tumor stage, and TNM stage in ESCC patients. In vitro gain- and loss-of-function experiments validate that USP44 acts as a tumor suppressor in ESCC. Xenograft assays further demonstrate that USP44 overexpression suppresses the growth of ESCC xenografts, as well as lymph node and lung metastasis. Analysis of collected ESCC tumor samples reveals downregulated USP44 expression and upregulated USP44 pan-succinylation, along with two opposing correlations: a negative correlation with Carnitine O-palmitoyltransferase 1 (CPT1A) and a positive correlation with CDK5 regulatory subunit-associated protein 3 (CDK5RAP3). Mechanistic studies identify CPT1A as a lysine succinyltransferase that specifically succinylates USP44 at lysine 543 (K543). Such CPT1A-mediated K543 succinylation triggers ubiquitination-dependent degradation of USP44, thus explaining the downregulation of USP44 observed in clinical ESCC samples. Moreover, ubiquitination proteomics combined with survival analysis identifies CDK5RAP3 as a key deubiquitination substrate of USP44. USP44 directly interacts with CDK5RAP3 and stabilizes CDK5RAP3 by removing its ubiquitin chains at lysine 166 (K166), in a manner dependent on the catalytic cysteine 282 (C282) within its USP domain. In rescue experiments, CDK5RAP3 overexpression reverses the promotion of malignant behavior in ESCC cells and the activation of the Wnt/β-catenin signaling pathway caused by USP44 silencing. Collectively, USP44 may serve as a promising therapeutic target for ESCC.

The catalytic hydrogenolysis of glucose to produce 1,2-propylene glycol (1,2-PG) has opened promising avenues for sustainable chemical production. However, traditional Ru-based catalysts suffer from issues such as high metal loading, poor dispersion, and a tendency to agglomerate under harsh conditions, leading to rapid deactivation. This work reports a highly dispersed, low-loading Ru catalyst supported on a magnesium–aluminum ferrite (MAFO) spinel to address these limitations. Strong covalent metal–support interactions (CMSI) between Ru species and the MAFO support not only achieve efficient stabilization of Ru nanoparticles but also promote their redispersion. Under optimized reaction conditions (518 K, 5 MPa H 2 , and 1 h), the Ru/MAFO catalyst achieves 100% glucose conversion and 59.3% selectivity to 1,2-PG. Notably, the catalyst maintains outstanding activity and stability after six consecutive reaction cycles. This study provides an efficient and robust catalytic strategy for 1,2-PG production from glucose, offering significant insights for designing high-performance and stable catalysts for biomass valorization.

FOLFOX has served as the standard chemotherapy regimen for advanced stages, specifically in the treatment of pancreatic, colorectal, and bladder cancers. However, the issues of excessive toxicity and prolonged treatment cycles persist. To address this limitation, we developed a novel methylated amino acid-modified lignin inspired by biological methylation, creating a pH-responsive charge-reversal drug delivery system for FOLFOX chemotherapy. This system stabilizes thymidylate synthase (TS) and combines with deoxyuridine monophosphate (dUMP) to demonstrate significantly improved therapeutic outcomes of FOLFOX against colorectal cancer (CRC). The FOLFOX-loaded nanodrug showed targeted antitumor activity against CRC and induced tumor cell death through multiple mechanisms, including apoptosis, necrosis, cell cycle regulation, DNA damage, and reactive oxygen species generation. Furthermore, the nano-formulation activated immune responses to enhance chemotherapeutic potency and effectively reducing renal toxicity associated with chemotherapy drugs. These findings suggest that protein methylation-mimicked lignin could be a valuable addition to current first-line chemotherapy options and holds promise for enhancing chemotherapy against solid tumors.
