The colloidal polystyrene (PS) was synthesized and decorated with silver nanoparticles (Ag NPs). The plasmonic Ag@PS nanocomposite was prepared by loading Ag NPs on PS microsphere through a seed-mediated in situ growth route. The property of Ag NPs deposited on the PS microsphere could be precisely controlled by adjusting the concentration of the chemicals used in the growth medium. The growth step is only limited by the diffusion of growing species in the growth media to the surface of the Ag seed. The Ag@PS prepared via the in situ growth method exhibited two advantages compared with the self-assembled PS/Ag. First, the high-density of Ag NPs were successfully deposited on the surface of PS as the electroless-deposited Ag seed process, which brings nearly three times SERS enhancement. Second, the rapid preparation process for in situ growth method (half an hour, 10 h for the self-assembled method). The PS/Ag could detect Nile blue A (NBA) down to 10–7 M by SERS. Furthermore, the plasmonic Ag@PS SERS substrate was used for pesticide identification. The on-site monitoring malachite green (MG) from fish was achieved by portable Raman spectrometer, and the limit of detection (LOD) was 0.02 ppm. The Ag@PS substrate has also shown capability for simultaneously sensing multiple pesticides by SERS.

It is still a challenging issue to achieve efficient and tunable fluorescent carbon dot (CD) powders. Herein, we report a novel and general solvothermal strategy to in-situ embedding CDs in trisodium citrate crystal matrix, and these CDs exhibit tunable emission from green to yellow and a high quantum yield up to 21.6% in solid state, comparable to that in solution. This intriguing fluorescence phenomenon may be caused by the space confinement from trisodium citrate crystal matrix, thus enabling CDs to effectively suppress the aggregation-induced luminescence quenching. The CD powders have been employed for fabricating white light-emitting devices on blue chips with adjustable color temperature. Moreover, solid-state lighting systems like flexible fluorescent films and plates have been demonstrated by using the CD powders as the luminescent medium. This work provides a facile way to achieve tunable solid-state fluorescence CD powders, which have promising applications in CDs-based luminescence devices.

In this work, a series of In(OH) 3 with abundant indium vacancies were synthesized by hydrothermal method using mixed solvent of ethylenediamine(En) and water for photocatalytic reduction of CO 2 with H 2 O vapor. The morphology, particle size, crystallinity, pore structure, and vacancy concentration of photocatalysts were successfully regulated by adjusting the ratio of En and water in mixed solvent, which were characterized by XRD, FT-IR, TG-DTA, SEM, HRTEM, UV–vis DRS, PL spectra, XPS, and EPR. Moreover, the effect of En/water ratio on the adsorption capacity to CO 2 and photo-electrical properties of In(OH) 3 were further investigated by in-situ FTIR, PL spectra, UV–vis DRS, CV, and EIS. In(OH) 3 prepared in mixed solution exhibited much higher photocatalytic activity for CO 2 reduction with H 2 O vapor compared to that prepared with water only solvent. The enhanced photocatalytic performance can be attributed to the special morphology, smaller particle size, larger BET surface area, and especially generated indium vacancies creating defect energy levels in the bandgap, which improved visible light absorption, carrier separation, and CO 2 chemisorption. This work paves the way to enable a non-visible-light response material with high visible-light photocatalytic activity by regulating vacancy concentration via a facile method.

Structural craniofacial abnormalities, particularly mandibular asymmetry (MA), are increasingly recognized as key drivers of orofacial pain and emotional comorbidities, although the underlying neural mechanisms remain unclear. This study aims to develop a preclinical MA model to investigate the dynamic interplay between craniofacial structural defects and neurobehavioral dysfunction. Longitudinal behavioral phenotyping including von Frey filaments test as well as open field and elevated plus maze tests reveals progressive sensory hypersensitivity and anxiety-like behaviors, with computational ethology revealing subtle but consistent alterations in the naturalistic behaviors. Whole-brain activity mapping reveal hyperactivation in the anterior cingulate cortex (ACC), whereas multi-omics profiling reveal cell type-specific transcriptional changes and synaptic reorganization within this region. Functional investigation including sparse labeling, electrophysiology, western blotting, and chemogenetics demonstrate that the ACC modulation regulated both pain and anxiety. These findings establish a causal association between structural craniofacial defects and maladaptive neural circuit remodeling, with the ACC emerging as a critical therapeutic target. The study provides a comprehensive framework for understanding how anatomical abnormalities translate into persistent neurological dysfunction and offers new avenues for mechanistically informed intervention.

Rechargeable metal–chlorine (Li/Na–Cl2) batteries potentially have a high energy density, but the significant amount of electrolyte consumed to produce active metal chlorides for reversible chlorine conversion severely limits their real electrochemical performance. Herein, we use a cathode with precast metal chloride in the graphene layers as the initial active material to save the sacrificial electrolyte and deliver a fundamentally different start-up operation mode for metal–chlorine batteries. Furthermore, the metal chloride confined by the graphene layers achieves in situ confining conversion with gaseous chlorine during long cycling, causing substantially improved cathode kinetics in a lean electrolyte. With this cathode, both Li/Na–Cl2 batteries demonstrate higher capacity and prolonged cycling performance. Typically, the obtained Na–Cl2 batteries could deliver a high areal capacity (3 mAh cm–2) and stable life over 300 cycles under lean electrolyte conditions (20–60 μL). This work demonstrates the practical significance of utilizing a graphene interlayer to confine metal chloride as an initial active material for rechargeable alkali-metal-Cl2 batteries.

Simple SummaryBactrocera dorsalisis a highly invasive polyphagous pest of fruit and vegetable, causing severe economic loss and trade restrictions by ovipositing inside hosts. Cryptic feeding habits of larval stages, strong flight ability of adults and prevalence of insecticide resistance reduce the efficiency of chemical control. Currently, the most cost-effective tool is olfaction-based trapping. Methyl eugenol (ME), a naturally occurring compound in some plants, alone or combination with insecticides has been widely used as a male attractant to monitor and controlB. dorsalispopulations for seven decades. Intense ME selection under laboratory conditions has resulted in the evolution of non- responsiveness inB. dorsalisand field management strategies based on ME has failed to eradicate recolonization ofB. dorsalisin some islands. However, the levels of ME responsiveness inB. dorsalisfield populations in China is unknown. In this study, we found that field populations had lower ME sensitivity compared to the susceptible strain. Furthermore, the results of olfactory organs, gene expressions and the bioassays showed that odorant binding protein (BdorOBP2, BdorOBP83b) and P450 may be involved in the lower sensitivity. The findings will guide the use of lures combined with insecticides and help to exploit molecular targets for the development of new attractants.AbstractBactrocera dorsalisis a notorious polyphagous pest in China, and its management strategies largely depend on methyl eugenol (ME), which has been widely used as an attractant to monitor and eradicateB. dorsalispopulations for seven decades. However, the non-responsiveness levels in fieldB. dorsalispopulations to ME is unknown. In this study, we monitored the response to ME in field populations from the four most heavily infested provinces in China, and the results showed that the populations had lower sensitivity to ME relative to GZS susceptible strain. The percent responsiveness of the lowest sensitivity population was 5.88-, 3.47-, and 1.47-fold lower relative to the susceptible strain at doses of 1, 10, and 100 µL of ME, respectively. Gene expression analysis and inhibitor assays further revealed that odorant binding protein (BdorOBP2, BdorOBP83b) and the P450 enzyme system may be associated with the lower response to ME. To our knowledge, this work is the first to report that the P450 enzyme system confers a lower responsiveness to lure insects. These findings provided valuable insights for exploiting ME non-responsiveness to protect sterile males from ME-based control strategies and the use of lures combined with insecticides.Keywords:methyl eugenol;non-responsiveness;odorant binding protein;P450;trapping

Engineering a versatile nanoplatform integrating imaging and therapeutic functions for efficient cancer treatment remains a grand challenge. Herein, a type of metal–organic framework (MOF)-based hybrid material for fluorescence imaging-guided synergistic phototherapy was prepared by in situ polymerization of a pyrrole (Py) monomer in the pores of a porphyrinic MOF. The resultant material (named PPy@MOF-525@HA) has a suitable size for cellular uptake, high degree of thermal stability and efficient photothermal conversion ability (η = 62.1%) upon near-infrared light irradiation, showing great potential for photothermal therapy. In addition, the porphyrinic MOF can trigger the generation of singlet oxygen (1O2) under the irradiation of visible light giving in vitro photodynamic therapy outcomes. Simultaneously, PPy@MOF-525@HA can also act as a contrast agent for cancer cell-specific targeting and fluorescence imaging to provide accurate guidance for cancer treatment. This work provides a promising platform for fluorescence imaging-guided synergistic phototherapy.

After transcription, most chloroplast precursor RNAs undergo further post-transcriptional processing including cleavage, editing, and splicing. Previous investigation has shown that the cleavage of the rpoA transcript and most editing sites, including accD - 1 , are defective in the knockout mutant of PDM1/SEL1, a PLS-type PPR protein, and that PDM1 is associated with the rpoA transcript. In this work, we found that the splicing of group II introns in trnK and ndhA is also affected in pdm1 . Co-immunoprecipitation mass spectrometry experiments were performed to identify proteins that are associated with PDM1. We obtained 126 non-redundant proteins, of which MORF9 was reported to be involved in RNA editing in chloroplast. Yeast two-hybrid assays showed that PDM1 interacts directly with MORF9, MORF2, and MORF8. RNA immunoprecipitation showed that PDM1 associates with the transcripts of trnK and ndhA , as well as accD - 1, suggesting that PDM1 is involved in RNA editing and splicing. Therefore, PDM1 is an important protein for post-transcriptional regulation in chloroplast.

Promising applications of lithium–sulfur batteries with high theoretical capacity are still severely limited due to the poor conductivity of sulfur, the polysulfide shuttle effect and volume expansion. Herein, low-cost and carbon/nitrogen-rich waste honeycombs are used to prepare in situ N-doped hierarchical porous carbon (INHPC) and firstly applied as a sulfur host by facile high-temperature carbonization combined with KHCO3 activation. The influence of mass ratios of the activator to honeycomb on the morphology and pore structure of the as-prepared carbon materials was investigated in detail. Among them, the optimized INHPC with a mass ratio of 4 : 1 presents block-like morphology with interconnected pore structure, while showing a high specific surface area of 1683.6 m2 g−1 and a large pore volume of 0.974 cm3 g−1. Moreover, the in situ N-doped carbon materials not only have good electronic conductivity but also strong chemical adsorption with polysulfide intermediates, hence effectively alleviating the shuttle effect. When used as the sulfur host, the as-obtained INHPC-4/S composite cathode with a sulfur content of 60 wt% delivers a high initial discharge capacity of 913.4 mA h g−1 and retains a reversible capacity of 538.3 mA h g−1 after 200 cycles at 0.2 C. Even at a current rate of 1 C, the first discharge capacity of 623.2 mA h g−1 can be obtained, simultaneously achieving the durable cycle life up to 500 cycles. These good electrochemical performances are ascribed to physicochemical synergistic adsorption of in situ N-doping and hierarchical porous structure as well as high ionic/electronic conductivity.

A novel 2D layered NbTiC solid-solution MXene was synthesized from its MAX phase via a wet chemical etching process. While ball milling the NbTiC MXene with MgH2, ultrafine bimetal NbTi nanocrystals were formed in situ with a grain size of 5 nm, which offer highly stable catalytic activity for the hydrogen storage reaction of MgH2. The MgH2-9 wt% NbTiC sample starts releasing hydrogen from 195 °C, which is 80 °C lower than that for the additive-free sample. At 250 °C, it releases approximately 5.8 wt% H2 within 30 min, and the fully dehydrogenated sample takes up 4.0 wt% H2 within 15 min even at 50 °C under 50 bar H2 pressure. DFT calculations reveal a charge transfer process from Ti atoms to Nb atoms in the NbTi cluster and a lower absolute value of the adsorption energy of H2 on NbTi. This would presumably benefit both the breakage of Mg–H bonding and the detachment of H2 from the NbTi surface, and consequently lead to good catalytic activity.

Solid-solution Li-ion cathode materials transform through a single-phase reaction thus leading to a long-term structural stability and improved cyclability. In this work, a two- to single-phase Li+-extraction/insertion mechanism is studied through tuning the stoichiometry of transition-metal Fe/V cations to trigger a transition in the chemical reactivity path. Tavorite triclinic-structured LiFe1−xVxPO4F (x= 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1) solid-solution powders were prepared by a facile one-step solid-state method from hydrothermal-synthesized and commercial raw materials. The broad shape of cyclic voltammetry (CV) peaks, sloping charge/discharge profiles and sloping open-circuit voltage (OCV) profiles were observed in LiFe1−xVxPO4F solid-solution cathodes while 0

The fluorescence labelling of plant hormone binding sites is an important analytical technique in research on the molecular mechanisms of plant hormone activities. The authors synthesised a jasmonic acid (JA)-conjugated ZnS:Mn quantum dot (QD) probe, with a cubic structure and average hydrodynamic sizes of about 17.0 nm. The maximum fluorescence emission of the probe was recorded at about 585 nm. The probe was used for fluorescence labelling of JA binding sites in mung bean seedling tissues. Analysis revealed that the probe exhibited high selectivity to JA binding sites and good performance in eliminating interference from background fluorescence in plant tissues. In addition, the probe did not exhibit any apparent biotoxicity, and is much more suitable than probes constructed from CdTe QDs for the analysis of biological samples.
