Nanocarrier-mediated delivery of double-stranded RNA (dsRNA) is a promising strategy for plant disease control. Our previous study has shown that the self-assembled ε-poly- l -lysine/carboxymethyl chitosan (ε-PL@CMCS) nanocarrier significantly improves the efficiency of RNA interference (RNAi) against Rhizoctonia solani AG3 TB. However, the molecular mechanisms underlying this enhancement and the potential ecological impacts on phyllosphere microbial communities remain unclear. In this study, we confirmed that ds RsGH1 @ε-PL@CMCS had no adverse effects on the growth and development of plants. Transcriptome analysis revealed that DEGs were significantly enriched in ‘SNARE interactions in vesicular transport’ pathway. Among them, ds RsGH1 @ε-PL@CMCS specifically upregulate the vesicle transport protein SEC22 in Nicotiana tabacum. Surface plasmon resonance (SPR) assay demonstrated that the ds RsGH1 @ε-PL@CMCS binds to SEC22 protein with 7.6-fold higher affinity than that of the naked ds RsGH1 . Silencing SEC22 in the ds RsGH1 @ε-PL@CMCS treatment reduced the silencing efficiency of RsGH1 from 53.3% to 39%, confirming its essential role. Concurrently, high-throughput sequencing revealed that SIGS treatments did not disrupt bacterial community structure but increased fungal diversity and suppressed the pathogen, while enriching beneficial fungi such as Tulasnella . Our findings elucidate a molecular link between nano-bioprotectant ds RsGH1 @ε-PL@CMCS-enhanced RNAi and host vesicle transport, while confirming the biocompatible and microbiome-modulating potential. This provides a dual perspective for developing efficient and sustainable RNAi-based strategies for protecting plants.

Semiconductor catalyst with high photocatalytic activity can be exploited via heterojunction. In this study, a new S-scheme SrTiO 3 /porous ZnO composite was rationally devised, successfully prepared by utilizing a two-step pyrolysis of SrTiO 3 /ZIF-8, and analyzed by various characterization technologies including XRD, SEM, TEM, BET, XPS, PL, UV–vis DRS, and photoelectrochemical and DFT theoretical calculations. A porous structure, tight contact, and a heterojunction formed between SrTiO 3 and porous ZnO (ZnOT) can be observed by SEM and TEM images. BET testing indicates that the SrTiO 3 /porous ZnO composite (S3ZT) shows the highest specific surface area (30.37 m 2 /g). The band gap values (E g ) of SrTiO 3 and ZnOT are around 3.17 and 2.95 eV, which agree with those obtained from DFT calculations. Compared to other samples, the SrTiO 3 /porous ZnO composite (S3ZT) shows higher light absorption and lower transfer resistance as demonstrated by UV–vis DRS and EIS results. S3ZT presents a superior photocatalytic efficiency of 48.8% in degrading 5 mg/L methyl orange (MO) irradiated by 1 h UV–vis light, which are 7- and 1.5-fold higher than pristine SrTiO 3 and ZnOT, respectively. Moreover, based on Mott-Schottky theory, active species trapping experiments, XPS determination, and DFT calculations (energy band gap and work function), it was shown to be reasonable to utilize the S-scheme charge migration process for an explanation regarding the better photocatalytic activity of SrTiO 3 /porous ZnO composite. Overall, this work will provide an effective protocol for devising and preparing semiconductor photocatalysts with S-scheme heterojunction by utilizing the superior characteristics of MOFs.

The application of solar interfacial evaporation technology in clean water production has garnered increasing attention in recent years, with thin-film evaporation being considered one of the most efficacious strategies to address the growing demand for high evaporation rates at moderate temperatures. This investigation presents the design of a Janus nanofiber film based on a self-pumping effect, comprising a hydrophobic layer (TPU) and a hydrophilic layer (PVA-(ε-PL)@MXene). This structure creates a self-pumping effect that promotes unidirectional transfer of liquids, effectively increasing water transfer efficiency and evaporation, achieving a maximum evaporation rate of 1.56 kg m–2 h–1 while maintaining 1.52 kg m–2 h–1 after multiple cycles. This Janus nanofiber film exhibits high performance in the 200–2500 nm range, demonstrating strong light absorption with an absorption efficiency of 87.69%, and rapidly increasing from room temperature to 57.8 °C in 3 min under 1 kW m–2. Furthermore, TPU/PVA-(ε-PL)@MXene exhibited substantial antimicrobial activity against E. coli (89.77%) and S. aureus (53.96%), attributed to the inhibitory effect of ε-PL on the biosynthesis of proteins and enzymatic biomolecules.

Insufficient bone regeneration and bacterial infection are two major concerns of bone repair materials. Poly-L-lactic acid (PLLA) have been widely used in bone tissue engineering (BTE), however, lack of osteogenic and antibacterial properties have greatly limit its clinical application. Herein, PLLA membrane was firstly treated with polydopamine (PDA), and then modified with ε-polylysine (ε-PL) and alginate (ALG) via layer-by-layer method. The (ε-PL/ALG)n composite layer coated PLLA ( [email protected] (ε-PL/ALG)n) could facilitates the adhesion and osteoblast differentiation of MC3T3-E1 cells. Furthermore, [email protected] (ε-PL/ALG) n presents an effective antibacterial efficacy against S. aureus and E. coli , and the bacterial survival rates of S. aureus and E. coli on [email protected] (ε-PL/ALG) 10 were 21.5 ± 3.5 % and 13 ± 2.1 %, respectively. This work provides a promising method to design PLLA materials with osteogenic and antibacterial activity simultaneously. Furthermore, the method is also an optional choice to construct multifunctional coatings on the other substrate.

In order to obtain the advanced photocatalyst with high performance for removing the gaseous formaldehyde, a new strategy with amination of titanium dioxide (TiO 2 ) and combination with reduced graphene oxide (rGO) is proposed in this work. TiO 2 was first aminated into amino-TiO 2 and then combined with rGO by an electrostatic self-assembly process to form the amino-TiO 2 /rGO photocatalysts. The structure and morphology were characterized by XRD , FTIR, and SEM, respectively. Physicochemical properties were measured by EIS, XPS , ESR , PL , and photocurrent measurements. The mechanism of the photocatalytic reaction was studied. Optimal amino-TiO 2 /rGO catalyst exhibits high catalytic activity and recyclability. The reaction rate constant of HCHO over this catalyst is approximately 9.8 × 10 −3 L mol −1 ·min −1 , which is 10.5 times higher than that of the commercial Degussa P25 TiO 2 . The analysis results from XPS and ESR indicates that the high catalytic activity could be mainly attributed to the imine formed by chemisorption of amino and HCHO. The reaction speed of formaldehyde photolysis increases as the concentration of HCHO on the photocatalyst surface increased. In addition, the introduction of graphene enhances carrier separation efficiency so that leads to more reactive radicals such as hydroxyl radicals (·OH) and superoxide radicals (·O 2 − ), leading to improved performance on formaldehyde photolysis. This could provide a useful method for highly efficient formaldehyde photocatalysis .

Two-dimensional (2D) evaporation systems could significantly reduce the heat conduction loss compared with the photothermal conversion materials particles during the evaporation process. But the normal layer-by-layer self-assembly method of 2D evaporator would reduce the water transportation performance due to the highly compact channel structures. Herein, in our work, the 2D evaporator with cellulose nanofiber (CNF), Ti 3 C 2 T x (MXene) and polydopamine modified lignin (PL) by layer-by-layer self-assembly and freeze-drying methods. The addition of PL also enhanced the light absorption and photothermal conversion performance of the evaporator due to the strong conjugation and π-π molecular interactions . After the combination process of layer-by-layer self-assembly and freeze-drying process, the as-prepared freeze-dried CNF/MXene/PL (f-CMPL) aerogel film exhibited highly interconnected porous structure with promoted hydrophilicity (enhanced water transportation performance). Benefiting these favorable properties, the f-CMPL aerogel film showed enhanced light absorption performance (surface temperature could be reached to 39 °C under 1 sun irradiation) and higher evaporation rate (1.60 kg m −2 h −1 ). This work opens new way to fabricate cellulose-based evaporator with highly evaporation performance for the solar steam generation and provides a new idea for improving the evaporation performance of 2D cellulose-based evaporator.

In this work, up-conversion phosphor CaF2:Yb3
+, Er3+ was synthesized by the co-precipitation method. X-ray Diffraction (XRD) and Photoluminescence Spectra (PL) were used to characterize the samples. The effects of annealing temperature and
Yb3+ and Er3+ concentrations on the luminescence properties were discussed. Strong green and red light were obtained under 980 nm laser excitation, the optimal annealing temperature was 600 °C, while the optimal doping concentration was 8 mol% Yb3+ and
0.6 mol% Er3+. The green (540 nm and 552 nm) and red (652 nm and 669 nm) up-conversion luminescence peaks can be ascribed to the transitions of 4S3/2-4I15/2 and 4F9/2-4I15/2, respectively. The
up-conversion luminescence intensities of the green and red emitting peaks can be changed by adjusting the concentration ratio of Yb3+ and Er3+. Hence, it can potentially be used as the red light conversion agent. The dependence of up-conversion intensities (CaF2:Yb3+,
Er3+) on excitation power indicated that two-photon absorption processes were responsible for green and red luminescence.

The failure of any phase in continuous multi-link immune response process can cause unsatisfactory outcomes, which might be improved by all-cancer-immunity-cycle boosted strategy. Herein, a nanoplatform Mn/CaCO 3 @PL/SLC is developed, which is based on palmitoyl ascorbate (PA)-liposome (PL) loaded with Mn-doped CaCO 3 nanoparticles (Mn/CaCO 3 NPs) and carbonic anhydrase (CAIX) inhibitor SLC-0111. The nanoplatform comprehensively amplifies all immune stages including tumor-associated antigens (TAAs) release and presentation, T cells activation and infiltration , as well as tumor cells destruction. In detail, Mn-triggered lipid peroxidation facilitates TAAs release and subsequent T cells activation to initiate immunity cycle. Additionally, SLC-0111 and PA amplify the infiltration and tumor killing activity of these effector T cells. The former polarizes the immunosuppressive tumor microenvironment to an immune-active phenotype and the latter enhances the function of tumor-infiltrating T lymphocytes. Importantly, Mn augments the all-immunity-cycle by promoting cGAS-STING pathway activation. In summary, the Mn/CaCO 3 @PL/SLC nanoplatform is verified to boost anti-tumor immunity and achieve outstanding immunotherapeutic effects in eradicating tumor and preventing tumor metastasis. Such an all-cancer-immunity-cycle boosted strategy is meaningful for antitumor immunotherapy .

Mustard gas is a kind of erosive poison with great harm and used as a chemical weapon since World War. It has suggested that the photocatalytic technology is an effective method to eliminate it. Because the small difference in molecular structure between 2-CEES and Mustard gas, and the less toxic of 2-CEES, 2-CEES is often used as a simulator to evaluate the photocatalytic activity of catalysts. In this work, symbiotic mixture of Bi 2 WO 6 and Bi 6 O 6 (OH) 3 (NO 3 ) 3 ·1.5H 2 O nanosheets doped with Mo (Mo-B-B) have been synthesized by a facile hydrothermal treatment. The samples were characterized by XRD, DRS, XPS, SEM, TEM, Raman, and PL. The photocatalytic activity of the samples was evaluated by measuring the degradation of 2-CEES under visible light irradiation. The results showed that the doped Mo reduce the Eg of bare symbiotic mixture and improve the separation efficiency of photo-generated carriers that is beneficial to photocatalytic activity. The optimum amount of doped Mo is 5% that exhibits the best activity for degradation for 2-CEES.

KBaPO 4 :Eu 2+ /Sm 3+ phosphor was synthesized via the high-temperature solid-phase reaction method. The structural properties, surface morphology, and optical properties of the synthesized samples were obtained by the X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), and fluorescence measurements. The XRD patterns indicate that the crystal structure of KBaPO 4 has not been changed by co-doped with two rare-earth ions. Under the excitation of 400 nm, the Eu 2+ and Sm 3+ co-doped KBaPO 4 phosphors showed typical emission peaks at 430 (blue), 562 (yellow), and 600 nm (red). Meanwhile, with the increase of the Sm 3+ content, the photoluminescent (PL) emission intensity of Sm 3+ increased until the content reaches 0.12. However, the PL intensity of Eu 2+ ions gradually decreased, which indicated that there was a possible energy transfer between the two ions. Therefore, the obtained results indicated that Eu 2+ /Sm 3+ co-doped KBaPO 4 is a promising phosphor for the use in white light-emitting diodes with near ultraviolet chips.

The cumulative harm caused by pesticide residues to environmental safety and human health is enormous, and the sensitive and selective detection pesticide in very trace amounts is currently a challenge. Herein, the biosensors for the ultrasensitive detection of acetamiprid (ACE) were proposed. The conducting polymer composite of phaseoloidin doped poly(3,4-ethyloxythiophene) (PL/PEDOT) was prepared with high surface area, excellent conductivity and stability, which was followed by the functionalization with poly(amidoamine) of the third generation (PAMAM). ACE aptamers were immobilized onto the platforms (PL/PEDOT and PAMAM/PL/PEDOT) for the development of ACE aptasensors. The concentration of ACE can be measured through both the increase of differential pulse voltammetry (DPV) signal change and the increase of the chronoamperometry (CA) signal change from the reduction of hydrogen peroxide catalyzed by PL/PEDOT. The ACE aptasensor based on PAMAM/PL/PEDOT exhibited linear ranges of 0.1 pg mL −1 -10 ng mL −1 and 0.1 fg-1.0 pg mL −1 , the detection limits as low as 0.0117 pg mL −1 and 0.0355 fg mL −1 (S/N = 3) through DPV and CA, respectively. Significantly, the response sensitivity of DNA/PAMAM/PL/PEDOT/GCE was 3.11 times higher than that of DNA/PL/PEDOT/GCE (by CA mode), proving that the PAMAM dendrimer can greatly enhance the sensing performance.
