Zero-dimensional perovskite Cs 4 PbBr 6 nanocrystals have attracted considerable attention for their potential in optoelectronic and sensing applications due to their excellent optoelectronic properties and environmental stability. However, their non-emissive property has limited their development in luminescent applications. Fortunately, the reversible phase transition between Cs 4 PbBr 6 and CsPbBr 3 nanocrystals provides a promising strategy to address this limitation. This study investigates the phase transition mechanism induced by the micro-environment factors, with a particular focus on the evolution of optical properties. Small droplets of Cs 4 PbBr 6 nanocrystals were exposed to air, and real-time monitoring of their color changes and photoluminescent emission characteristics was conducted. The results reveal that the large surface area of the droplet facilitates solvent evaporation, which accelerates the phase transition of Cs 4 PbBr 6 nanocrystals, leading to a significant enhancement in photoluminescent brightness. By quantitatively correlating environmental humidity with the phase conversion rate, this work highlights the critical role of humidity in modulating the conversion kinetics. Furthermore, the study systematically explores the mechanism of tuning the photoluminescent emission peak by adjusting the surface ligands, which enables the development of an environment-responsive, color-changing optical device based on droplet dynamics.

The interfacial arrangement of surfactant molecules dictates the properties of adsorption films, rendering the molecular adsorption mechanisms fundamentally critical. This study integrates interfacial dilational rheology with molecular dynamics simulation to unravel the adsorption mechanism of renewable sorbitol-alkylamine surfactant (SAAS-C12) at air/water (A/W) and n-decane/water (D/W) interfaces. We report the first discovery that hydrogen-bond switching governs the precise modulation of interfacial film strength: at the A/W interface, the transition from intramolecular hydrogen-bonded rings (low-concentration, irreversible adsorption) to intermolecular hydrogen-bonded networks (high-concentration, reversible adsorption) drives a distinctive bimodal dilational modulus trend while confining relaxation processes to slow molecular rearrangement. At the D/W interface, n-decane molecules weaken the interaction between surfactant alkyl chains by competing with surfactant molecules via van der Waals forces, converting the high-concentration modulus maximum to a gradual-decay plateau and concurrently redirecting dominant relaxation toward rapid diffusion exchange. Clarifying the mechanism of the interfacial dilational modulus dominated by hydrogen bonds helps to design green surfactants with good foam performance, showing promise for sustainable applications in the food industry, pharmaceutical delivery, and enhanced oil recovery.

Catalytic activation of peroxymonosulfate (PMS) by transition metal oxide is an effective strategy for water pollution remediation. However, the application of manganese oxides (MnO X ) is hampered by particle agglomeration and manganese ions leaching during PMS activation process, which compromise catalytic efficiency and pose environment risks. To address these limitations, MnO X -embedded hydrochar composite (HC P -Mn) was synthesized via hydrothermal-co-calcination method, utilizing hydrochar as support matrix to mitigate MnO X agglomeration and metal leakage. Refractory antibiotic florfenicol and sulfamethoxazole were used as target pollutants to assess HC P -Mn’s removal efficiency in peroxymonosulfate (PMS) activation system. Crucially, this work provided a deep insight into mechanism of PMS catalytic activation by HC P -Mn, particularly synergistic interplay between MnO X and hydrochar. Comprehensive experimental and material characterization revealed that delocalized π-electron and carbonyl groups on hydrochar enhanced electron transfer, which could directly react with PMS and strengthen dual redox circulation of Mn(II)/Mn(III)/Mn(IV) constructed by MnO X , this synergy dramatically boosted production of sulfate radical (SO 4 ‧− ) and hydroxyl radical (‧OH) via PMS activation. Consequently, HC P -Mn exhibited a reaction rate 6.9-fold higher than manganese-free hydrochar, achieving > 90 % removal of both antibiotics in 60 min. Furthermore, HC P -Mn demonstrated exceptional robustness, influence of co-existing anions and pH variations on its removal efficiency were relatively limited, enabling effective removal in real water matrices and mixed- systems. Critically, HC P -Mn exhibited good chemical stability for controllable manganese leaching and over 80 % removal efficiency after five consecutive reaction cycles. This work integrated concept of π-electron, carbonyl groups and manganese’s valence circulation for promoting PMS activation, presented a feasible hydrothermal-co-calcination method to fabricate efficient and stable MnO X -embedded hydrochar composite, synergistic electron-transfer mechanism was verified and significant potential strategy for practical antibiotic treatment in water was proposed.

Plants perceive microbe-derived molecular patterns to initiate the innate immune system. The csp22 peptide, derived from bacterial cold shock protein, is uniquely recognized by cold shock protein receptor (CORE) in Solanaceae plants, yet the signaling pathway remains largely obscure. In this study, we identify that tomato csp22-activated kinase 1 (SlCAK1), belonging to the receptor-like cytoplasmic kinase subgroup VII, is essential for csp22-induced immune responses and resistance to bacterial wilt disease. SlCAK1 is rapidly recruited to the csp22 receptor complex, which results in SlCAK1 phosphorylation upon csp22 treatment. Notably, csp22-induced phosphorylation specifically occurs at the Ser60 residue in the N terminus of SlCAK1, which is critical for SlCAK1 function in immunity. Interestingly, the conservation of Ser60 is unique to Solanaceae plants. Taken together, our findings reveal the pivotal role of SlCAK1 in transducing csp22-triggered immune signaling and provide a novel activation mechanism for receptor-like cytoplasmic kinases that involves phosphorylation in the N terminus.

The triazine herbicides simetryn and prometryn may cause damage to nontarget crops due to persistent contamination of agricultural water. Photocatalysis is a promising technology for the degradation of agricultural pollutants. This study provides the first systematic integration of photocatalytic herbicide degradation with live plant bioassay validation using cost-effective Fe3O4/SiO2/TiO2 magnetic photocatalysts synthesized by a simple coprecipitation method suitable for large-scale production. The phytotoxicity of herbicide-containing water was evaluated using pak choi, a crop sensitive to triazines. Both herbicides were completely decomposed in water within 240 min after UV irradiation, and their phytotoxicity also disappeared. In the plant toxicity evaluation, prometryn exhibited temporary high toxicity exceeding that of the untreated 10 ppm solution during the photodegradation process. In previous photocatalyst studies, evaluations relied on either chemical analysis or biological tests. In this study, we developed a new rapid toxicity screening technique using plant seedlings and established a safety evaluation protocol integrating chemical analysis and plant toxicity tests. This method represents the first approach to comprehensively evaluate the safety of agricultural water.

Dysregulation of cytoskeletal proteins has been found in response to DNA damage stress, yet the functional role of cytoskeletal proteins in DNA repair remained unexplored. Here, we found that DNA-damaging agents induced substantial upregulation of smooth muscle-specific cytoskeletal protein smoothelin (SMTN) in colorectal cancer (CRC) cells. Silencing SMTN abrogated G2/M arrest, exacerbated DNA damage, and markedly enhanced the chemosensitivity of CRC cells to various DNA-damaging agents. Notably, SMTN could rapidly accumulate at DNA damage sites within 1 min after laser irradiation, which was indispensable for the initiation of homologous recombination (HR) repair. Mechanistically, SMTN stabilized RAD51 by disrupting its interaction with its E3 ubiquitin ligase HUWE1, thereby maintaining the process of HR repair. To explore the therapeutic role of SMTN, customized cell membrane infused biomimetic liposomes were constructed to ensure rapid delivery of SMTN siRNA specifically into HCT-116 cells, yielding significantly enhanced anti-cancer effects of irinotecan and fuzuloparib both in vitro and in vivo . To summarize, our findings revealed a novel function of SMTN in DNA damage repair and provided a therapeutic strategy of targeting SMTN to enhance the efficacy of DNA damage agents.

Reduced nicotinamide adenine dinucleotide (NADH) salvage pathway reconstitution is a crucial step toward autonomous artificial cells. In living systems, D-ribose is a fundamental precursor intricately involved in the synthesis of nucleotides, nucleic acids, and critical metabolic pathways. An NADH synthesis pathway in artificial cells starting from D-ribose was constructed with five-enzyme cascade containing ribokinase, ribose-phosphate pyrophosphokinase, nicotinamide phosphoribosyltransferase, nicotinamide mononucleotide adenylyltransferase, and formate dehydrogenase (RK, RPPK, NAMPT, NMNAT, and FDH), which efficiently converted 10 mM D-ribose into 415 μM NADH within 80 minutes under optimized conditions. The produced NADH was further used to drive the amino acid metabolism, i.e., to convert NH4+ and α-ketoglutarate to glutamate by introducing additional glutamate dehydrogenase (GDH) inside artificial cells. The successful reconstitution of NADH synthesis pathway lays the foundation for fabricate artificial cells with complicated metabolic net works.

Brassica napus (oilseed rape) is sensitive to boron (B) deficiency and exhibits young leaf curling in response to low-B stress at the seedling stage, which leads to reduced photosynthesis and plant growth. So far, no gene has been identified to be involved in B deficiency induced leaf curling. Our previous results showed the transcription factor BnaA1.WRKY53 might be involved in B-deficiency tolerance. However, altered BnaA1.WRKY53 expression does not influence B concentration in shoot, root and leaf cell walls, which suggests BnaA1.WRKY53 might be involved in other biological processes. Indeed, phenotypic and anatomical analyses revealed that BnaA1.WRKY53 negatively regulated the leaf curling induced by leaf epinasty by suppressing the overexpansion of palisade cells under B deficiency. Further transcriptome enrichment analysis of differentially expressed genes (DEGs) between wild-type and BnaA1.WRKY53 overexpression line showed auxin response pathway was enriched. In addition, Arabidopsis DR5::GFP auxin reporter line showed B deficiency caused predominant auxin signal accumulation in the adaxial side and concomitant adaxial cell expansion, which indicated that B deficiency may induce leaf curling by altering auxin distribution. Phytohormone quantification and gene expression analysis demonstrated that BnaA1.WRKY53 prevent auxin overaccumulation in leaves by suppressing auxin biosynthetic genes under B deficiency. Furthermore, exogenous 1-naphthlcetic acid (NAA) treatment experiments revealed that high auxin could induce leaf curling and BnaA1.WRKY53 expression. Overall, these findings demonstrate that auxin and the transcription factor BnaA1.WRKY53 synergistically regulate leaf curling to maintain an optimal leaf area under B deficiency, and providing novel insights into the resistance mechanisms against B-deficiency-induced leaf curling in oilseed rape.

Legumes are important sources of dietary lipids, and lipidomic analysis of legumes using UPLC-QTOF-MS is crucial for human health. This study characterized and compared the lipid profiles of black soybean, mung beans, chickpeas, peas, fava beans, cowpeas, adzuki beans, and kidney beans, and investigated the effects of soaking and cooking. Sixteen subclasses comprising 520 lipids were identified, with 170 differential lipids among the eight legume types. Soaking for 12 h decreased the fatty acids (FAs) and lysophospholipids (LPLs), and increased the triacylglycerols, ceramides, phosphatidylethanolamines, diacylglycerols (DGs), monogalactosyldiacylglycerols (MGDGs), phosphatidic acids (PAs), phosphatidylinositols (PIs), and phosphatidylserines (PSs). Cooking for 20–55 min reduced the LPLs, FAs, phosphatidylglycerols, and sphingomyelin 42:8;O2, but increased the MGDG 36:4, MGDG 36:3, MGDG 36:2, digalactosyldiacylglycerol (DGDG) 36:4, DGDG 36:5, PA, PI, and PS levels. These findings offer valuable insights for legume selection and authenticity assessment and elucidate the effects of soaking and cooking on legume seed lipids.

Photocatalytic water splitting is hindered by flammable H 2 /O 2 cogeneration and energy-intensive post-separation. Herein, a Ru/WO 3 -MWCNTs ternary composite is designed to address these bottlenecks via a hydrogen spillover-based strategy: direct H* storage instead of gaseous H 2 generation to achieve H 2 /O 2 separation. Photogenerated H* from Ru active sites migrate through WO 3 , then is immobilized on MWCNTs as C H bonds for hydrogen storage, enabling exclusive O 2 release during photocatalysis. This composite exhibits an oxygen evolution rate (OER) of 645.28 μmol g −1 h −1 (outperforming binary counterparts) with no detectable gaseous H₂ during irradiation, alongside a stable H₂ storage capacity of 2.23 wt%. The stored hydrogen is thermally releasable, and the entire cycle of photocatalytic water splitting (hydrogen storage with O 2 evolution) and thermal H 2 release maintains excellent cyclic stability. This work establishes hydrogen storage-aided in-situ H 2 /O 2 separation as a universal strategy for addressing the core bottlenecks in photocatalytic water splitting.

The practical application of LiBH 4 for solid-state hydrogen storage is hindered by its sluggish kinetics and high thermodynamic stability. To address these challenges, we constructed a multiphase catalytic system within LiBH 4 by incorporating nano-BaTiO 3 and carbon nanotubes (CNTs) through ball milling. The composite of LiBH 4 , 20 wt% BaTiO 3 and 20 wt% CNTs exhibits significantly enhanced dehydrogenation properties, with an initial temperature as low as 223 °C and a peak desorption temperature of 353 °C, releasing 8.2 wt% H 2 at 500 °C. The modified composite demonstrates markedly improved reversibility and kinetics, evidenced by a retained capacity of 4.1 wt% after the 6th cycle and a substantially decreased activation energy of 123 kJ mol −1 . During the first dehydrogenation, LiBH 4 reacts in-situ with BaTiO 3 to form Li 3 BO 3 , BaB 6 , and TiO 2 phases. These products, in conjunction with CNTs, form a multifunctional catalytic framework. Among them, BaB 6 serves as the nucleation site, TiO 2 acts as the active catalyst, and Li 3 BO 3 facilitates ion transport, collectively enhancing the reaction kinetics and cycling stability of LiBH 4 . Meanwhile, the CNTs provides dual functions of confinement and excellent thermal conductivity, which suppressing particle aggregation and enhancing thermal diffusion rate. Consequently, the composite exhibits a lower decomposing temperature, rapider kinetics, and enhances reversibility compared with the as-milled LiBH 4 . This work provides an effective strategy of in-situ engineering a multiphase interface to attain high-performance solid-state hydrogen storage materials.

Pectins, as health-promoting factors, often degrade during fruit post-harvest storage. Changes in structure and physicochemical properties of pectic polysaccharides from ‘Huangguan pear’ after 0, 3, and 5 months of 4 °C storage and their lipid-lowering activity were studied. The degree of methylation of pectic polysaccharides decreased from 79.31% to 71.88%. Galacturonic acid content decreased while side chains, molecular weight and viscosity increased, and surfaces became rougher. Decreased binding ability on four bile salts but enhanced inhibitory ability on cholesterol micelles, pancreatic lipase, and cholesterol esterase were displayed. Cell experiments showed pectic polysaccharides reduced total cholesterol and triglycerides levels by downregulating relative mRNA expression of fatty acid synthase (FAS) and sterol regulatory element-binding protein-1c (SREBP-1c), and pears with shorter storage exhibited higher protection against oxidative stress and lipid accumulation in HepG2 cells. Overall, pectin in fresher pears showed more comprehensive lipid-lowering effects, but pears with longer storage still have specific lipid-lowering values.
