Summary Ethylene exerts a divergent role in modulating plant organ abscission. Spermidine (Spd) shares a common precursor for de novo biosynthesis with ethylene, but the antagonistic role between them in the regulation of plant organ abscission remains largely elusive. Here, RNA-sequencing of abscission zones from ethylene-treated sweet orange ( Citrus sinensis L.) fruit led to the identification of two ethylene-responsive factors (ERFs), CsERF113 and CsERF7. CsERF113 functioned in promoting fruit abscission and suppressed Spd accumulation, whereas CsERF7 exhibited an opposite trend. CsERF113 and CsERF7 were verified to act as a transcriptional repressor or an activator of CsSAMDC1 / 2 / 3 encoding S -adenosylmethionine decarboxylase (SAMDC), an enzyme responsible for Spd biosynthesis, by binding directly to their promoters in an ethylene-dependent manner. Moreover, CsSAMDC1 / 2 / 3 functioned to inhibit fruit abscission by promoting Spd synthesis. Interestingly, CsERF7 and CsERF113 transcriptionally repressed each other to modulate the ethylene-mediated downregulation of CsSAMDC1 / 2 / 3 , forming an antagonistic regulatory circuit that could be negatively orchestrated by exogenous Spd. Taken together, our results uncover that CsERF113 and CsERF7 integrate the ethylene signal to antagonistically regulate CsSAMDC1 / 2 / 3 -mediated synthesis of Spd and fruit abscission. This study provides important insights into understanding the molecular mechanisms by which ethylene and Spd antagonize to modulate fruit abscission.

High Mn 2+ doping concentration can lead to the formation of high-density defects/trap states, which serve as non-radiative recombination centers, seriously restricting the energy transfer efficiency from the host nanocrystals to Mn 2+ . Herein, we introduce Cd 2+ into Mn 2+ -doped CsPb(BrCl) 3 nanocrystalline (NCs) film to effectively suppress non-radiative recombination. The analysis of the structure and composition confirmed the phase and chemical composition of the Cd 2+ -Mn 2+ co-doped CsPb(BrCl) 3 NCs film. Steady-state and time-resolved photoluminescence (PL) spectra revealed the enhanced optical properties of the co-doped CsPb(BrCl) 3 NCs film. The Mn 2+ emission peak is studied in the temperature range of 80 K–300 K. Strong electron-phonon coupling causes an anomalous blueshift and linewidth broadening of the Mn 2+ emission peak with increasing temperature. Temperature-dependent PL spectra confirmed that the energy transfer between the exciton emission peak and the Mn 2+ emission peak was regulated through Cd 2+ doping, achieving the negative thermal quenching effect. This study utilized C 9 H 23 NO 3 Si (APTES) for the surface encapsulation of the NCs film to enhance their stability. Substituting Pb 2+ with Cd 2+ and Mn 2+ enhances the stability of the nanocrystals and alleviates lattice distortion within the [PbCl 6 ] 4- octahedral framework. The experimental results indicate that the Mn 2+ emission peak of the co-doped CsPb(BrCl) 3 NCs film retains 80.7% of its luminescent intensity after 31 days of storage in air, thereby confirming its excellent optical stability.

Developing materials that combine ultrahigh adsorption capacity with facile solid–liquid separation remains a central challenge in interfacial science for fluoride pollution control. Current research on metal-organic frameworks (MOFs) as adsorption carriers mainly emphasizes structural design, while byproducts generated during MOF synthesis are commonly regarded as useless impurities and consequently neglected. Herein, we report a previously overlooked crystalline byproduct, La(HCOO) 3 , which was initially formed via N , N -dimethylformamide (DMF) hydrolysis during the solvothermal synthesis of La-BDC and can be subsequently controllably synthesized by the deliberate introduction of formic acid. Owing to its uniform and well-defined particle size, La(HCOO) 3 can be readily separated from La-BDC by simple physical sieving, enabling its direct recovery. Inspired by this feature, we propose a “waste-to-resource” strategy by directly employing La(HCOO) 3 as a functional material for fluoride adsorption flotation for the first time. Under optimized conditions, La(HCOO) 3 exhibits a fluoride adsorption efficiency of 96.29% and a flotation separation efficiency of 94.22%, yielding a low effluent turbidity of 4.37 NTU and excellent selectivity. The adsorption process follows a monolayer chemisorption model with a maximum theoretical adsorption capacity of 206.61 mg/g, outperforming many deliberately designed adsorption carriers. Combined characterization and density functional theory (DFT) calculation reveal that fluoride adsorption is governed by the synergistic effects of ligand exchange and electrostatic attraction, while sodium dodecyl sulfate (SDS) enables efficient flotation recovery through chemical adsorption and electrostatic interactions with La(III) sites. This study reveals a novel approach for the interfacial valorization of MOF byproducts and a sustainable route for fluoride remediation.

Indole-3-acetic acid (IAA), one of the most important phytohormones, plays critical roles in plant growth, development, and stress response. However, minimally invasive and in-situ monitoring of IAA in living plants remains challenging due to the complex biological matrix and the lack of suitable in vivo sensing platforms. Herein, we report a minimally invasive microneedle electrochemical sensor for in vivo monitoring of IAA in plant leaves. A polymer microneedle array was fabricated and coated with a conductive Au layer, followed by electropolymerization of a molecularly imprinted poly(o-phenylenediamine) (poly-OPD) recognition film using IAA as the template molecule. The resulting microneedle sensor exhibited a selective electrochemical response toward IAA with good anti-interference capability against common electroactive plant metabolites. The sensor showed a linear response toward IAA over a wide concentration range with a low detection limit (0.44 μM). The microscale structure of the microneedles enabled minimally invasive insertion into plant tissues while maintaining structural integrity and stable electrochemical performance of the sensing platform. The developed sensor was further applied for in vivo monitoring of IAA fluctuations in tomato leaves under different physiological conditions. Distinct dynamic electrochemical response patterns were observed between normal and drought-stressed leaves, demonstrating the potential of the microneedle platform for plant physiological analysis and precision agriculture applications. This work provides a promising strategy for minimally invasive phytohormone sensing in living plants and expands the application of microneedle electrochemical devices in plant bioanalysis.

Based on our previous discovery that alkyl-side-chains in the aryl polymers have a positive effect on dielectric properties of the polymers, this work further investigates the side-chain effect by a hydrogenated bio-based cardanol monomer with a long pentadecyl alkyl side chain. The monomer was functionalized by introducing the thermocrosslinkable benzocyclobutene groups, and its cured product displayed a dielectric constant ( ε ) of 2.59 and a dielectric loss ( tan δ ) of 5×10 -4 at a high frequency of 10 GHz. In contrast, a controlling polymer with methyl side chain exhibited a ε of 2.84 and a tan δ of 1.4×10 -4 , respectively. Such data indicate that the long alkyl-side-chains can effectively improve the dielectric properties of the aryl polymers. Moreover, the cured hydrogenated bio-based cardanol also exhibited good hydrophilic properties with the water absorption of 0.16% even immersing it in boiling water for 96 h. These results imply that bio-based cardanol is a potential candidate for the preparation of the low- k materials used in microelectronic industry.

Background Asthma is a chronic disease characterized by airway remodeling, which results in a progressive decline in lung function. Senkyunolide A is one of the effective components of ligusticum chuanxiong Hort, it shows protective effects on many human diseases. However, the role of Senkyunolide A in asthma remains unclear. Results In our study, we established an asthma mouse model by ovalbumin (OVA) sensitization and challenge, and Senkyunolide A (20 mg/kg and 40 mg/kg) was given by intraperitoneal injection. For in vitro study, lung epithelial BEAS-2B cells were treated with TGF-β1 to induce epithelial mesenchymal transformation. Our study showed that Senkyunolide A (40 mg/kg) alleviated airway injury, inflammatory infiltration and airway remodeling induced by OVA in asthma mice. Meanwhile, Senkyunolide A (40 μM) recovered the high level of cell migration and profibrotic factors expression induced by TGF-β1. Mechanistically, Senkyunolide A abolished the effect of OVA or TGF-β1 on Smad2/3 phosphorylation at site Ser 465/467 /Ser 423/425 in mice or BEAS-2B cells and inhibited the activation of NLRP3 inflammasome induced by OVA. Conclusions In total, our study indicated that Senkyunolide A alleviated airway damage and airway remodeling in asthmatic mice and regulated the progress of asthma by inhibiting the TGF-β/Smad2/3 signaling pathway and NLRP3 activation.

Perovskite light-emitting diodes (PeLEDs) employing CsPbX 3 nanocrystals (NCs) face persistent challenges in balancing emission efficiency and spectral stability due to surface halide vacancies, which trigger nonradiative recombination, halide phase segregation, and self-doping effects. In this work, we address these limitations by introducing 3,5-dicarboxyphenylboronic acid (3,5-DA) as a multifunctional bidentate ligand additive. The unique coordination architecture of 3,5-DA, featuring multiple chelating groups, enables strong binding affinity to perovskite NC surfaces. This interaction effectively passivates halide vacancies while suppressing ion migration and defect formation. The optimized CsPb(Br/I) 3 NCs exhibit enhanced stability and suppressed nonradiative losses, enabling high-performance white LEDs (WLEDs). At a driving current of 10 mA, the fabricated WLEDs demonstrate a luminous efficiency of 10.32 lm·W −1 , a CIE coordinate of (0.3379, 0.3391), a correlated color temperature (CCT) of 5260 K, and an external quantum efficiency (EQE) of 6.48 %. This work provides a ligand engineering strategy to concurrently resolve efficiency-stability trade-offs in PeLEDs.

With the advancement of automotive intelligence and electrification, ethylene glycol (EG), as a critical component in antifreeze and coolant systems, has gained increasing industrial significance. However, the volatile nature of EG poses potential health hazards, making the development of high-performance EG gas sensors an urgent priority. In this study, a CuO-In(OH) 3 Type II p-n heterojunction was directly fabricated through a solvothermal method followed by 200°C annealing. The developed CuO-In(OH)₃-based gas sensor demonstrates exceptional EG sensing performance, exhibiting a response magnitude of 21.3 toward 50 ppm EG at 95°C – 7.9 times higher than that of pure CuO (2.7). Notably, the operating temperature was reduced from 120°C (pristine CuO) to 95°C while maintaining excellent repeatability (6 cyclic tests) and long-term stability (26-day continuous operation). The first engineered heterojunction, characterized by its nanoflower-cube hierarchical architecture, not only provides a novel strategy for designing efficient EG gas sensors but also demonstrates promising potential in environmental safety assurance.

The viscoelasticity of shear thickening fluid (STF), a crucial property in the protective composite applications, with different silica nanoparticle concentrations in ionic liquid, 1-butyl-3-methylimidizolium tetrafluoroborate ([C4min]BF4), was studied at different temperatures and with shear frequencies through oscillatory shear, respectively. All STFs present strain thickening behavior. With increasing silica nanoparticle concentration, the critical shear strain for the onset of strain thickening decreased, while the complex viscosity, storage modulus, and loss modulus increased significantly. The critical shear strain increased with an increase of temperature, while the complex viscosity, storage modulus, and loss modulus decreased notably. The critical shear strain was constant with increasing the frequency of strain, while the complex viscosity decreases slightly. The storage modulus and loss modulus were independent with frequency in the strain thickening region. Nanoparticle clusters leading to strain thickening were demonstrated. The viscoelastic response of STFs to varying silica nanoparticle content, temperature, and frequency investigated here will help to design the specific application of STFs in soft protective composites and damping devices.

The NASICON (Sodium super ion conductor)-type of Na 3 V 2 (PO 4 ) (NVP) has a great potential for energy storage application due to its high voltage plateau, three-dimensional (3D) ionic diffusion channel, perfect thermal stability, and high structural robustness. Here, Na 3 V 2 (PO 4 )-based composites with 3D porous carbon skeleton structure were synthesized via hydrothermal methods . After a series of hydrolysis and polymerization processes, transparent colloid mainly containing (NH 4 ) 4 Na 2 V 10 O 28 phase was formed. The 3D porous hydrogel with the (NH 4 ) 4 Na 2 [V 10 O 28 ]·10H 2 O phase was produced by adjusting the reaction time. The product has a lamellar structure , and its ion is suitable to grow the nanosheets , and the present PO 4 3- groups may be distributed in the (NH 4 ) 4 Na 2 [V 10 O 28 ]·10H 2 O phase of the interlayer structure, leading to the enhanced electronic conductivity . The 3D porous Na 3 V 2 (PO 4 )/C (NVP/C) with the size of 100–200 nm particles can be used as cathode for sodium ion batteries . The NVP/C delivers a specific capacity of 62.1 mAh g −1 at 10 C. The excellent stability of NVP/C can be obtained with 98% capacity retention after 140 cycles at 1 C. After 2000 cycles (5 C), the capacity is still 80.4 mAh g −1 , with the capacity retention of about 86%. Our encouraging results may boost further studies of SIBs device by smart engineering of the electrode materials.

The poor cycling performance of Li-rich manganese-based (LMR) cathodes is one of the challenges that need to be urgently overcome. Enhancing the stability of the layered structure responsible for lithium-ion diffusion is an effective way to improve the cycling performance. Layered structures are mainly formed during the high-temperature solid-phase reaction, whereas the prolonged and constant-high-temperature calcination conditions in conventional calcination procedure may pose a threat to the layered structural stability. Thus, in order to optimize the formation environment of layered structures under high-temperature solid-phase reaction, we have designed suitable temperature-controlled strategies for each stage of layered structure formation, gradual maturation, and post-treatment, respectively, referred to as the 3-stage calcination strategy. This calcination strategy contributes to the formation of a more ordered and stable layered structure, which significantly improves the cycling performance of LMR cathodes (capacity retention rate of 85.2 % after 200 cycles at 1C). The shortening of the constant high temperature calcination time helps to further reduce the production cost of the batteries . The design concept of this work is to regulate the formation process of layered structures in stages, which provides inspiration for the efficient and controllable synthesis of electrode materials with excellent structural stability at low production cost.

In this work, high stable perovskite solar cells (PSCs) based carbon counter electrode were fabricated in the air environment with 30% of humidity, in which the perovskite CH 3 NH 3 Pb(I 1- x Br x ) 3 were used as the absorber. We investigated the effect of the different Br-doping ( x = 0.00, 0.10, 0.15, 0.20, 0.25, 0.30) on the devices performance and found that the appropriate amount of Br-doping could effectively improve crystallinity of the perovskite film and enhance the light absorption. When the doping-ration x was 0.25, the device exhibited the best performance with the efficiency of 9.99% with active area of 0.2 cm 2 under the irradiation of 100 mW/cm 2 air mass 1.5 global (AM1.5G) sunlight. By electrochemical impedance spectroscopy (EIS) measurement, we found that the introducing of Br − into the perovskite film could reduce the carrier recombination loss . Finally, the stability test of the PSCs was carried out and the result showed that the device still keep 96.23% of the initial efficiency after being stored in the air for 56 days (1344 h), which show an excellent stability.
