Safety concerns regarding traditional lithium-ion batteries have garnered widespread attention, and solid-state batteries, with their superior safety and energy density, have emerged as the primary direction for the development of next-generation rechargeable batteries. Among various solid-state electrolytes, PVDF–HFP-based polymer solid-state electrolytes have garnered significant attention owing to their good flexibility, excellent processability, and mechanical strength. However, their low room-temperature ionic conductivity limits their practical application. To address this, this study adopts a composite quasi-solid-state electrolyte approach by introducing nano-BaTiO 3 into the PVDF–HFP-based quasi-solid-state electrolyte system and employs UV light curing technology for rapid fabrication. This approach not only enhances the electrolyte’s ionic conductivity but also strengthens its mechanical strength. Experimental results indicate that the introduced nano-barium titanate may restrict the movement of polymer chains, producing a synergistic effect with the cross-linked network formed by UV curing. This enables the electrolyte to achieve an ionic conductivity of 7.01 × 10 −4 S cm −1 at room temperature. At a current density of 0.2 mA cm −2 , the system can operate stably for 2200 h. At a 0.2 C rate, the battery exhibited a capacity retention of 93.55% after 120 cycles. This study provides a feasible approach for the preparation of safe and highly stable quasi-solid-state electrolytes.

Our previous study found that CpG oligodeoxynucleotides 1826 (CpG 1826), combined with mucin 1 (MUC1)-maltose-binding protein (MBP) (M-M), had certain antitumor activity. However, this combination is less than ideal for tumor suppression (tumors vary in size and vary widely among individuals), with a drawback being that CpG 1826 is unstable. To solve these problems, here, we evaluate MF59/CpG 1826 as a compound adjuvant with M-M vaccine on immune response, tumor suppression and survival. The results showed that MF59 could promote the CpG 1826/M-M vaccine-induced tumor growth inhibition and a Th1-prone cellular immune response, as well as reduce the individual differences of tumor growth and prolonged prophylactic and therapeutic mouse survival. Further research showed that MF59 promotes the maturation of DCs stimulated by CpG1826/M-M, resulting in Th1 polarization. The possible mechanism is speculated to be that MF59 could significantly prolong the retention time of CpG 1826, or the combination of CpG 1826 and M-M, as well as downregulate IL-6/STAT3 involved in MF59 combined CpG 1826-induced dendritic cell maturation. This study clarifies the utility of MF59/CpG 1826 as a vaccine compound adjuvant, laying the theoretical basis for the development of a novel M-M vaccine.Keywords:MF59;CpG 1826;compound adjuvant;tumor vaccine;MUC1-MBP;dendritic cells

This study investigated the immunomodulatory effects of soft-shelled turtle (Pelodiscus sinensis) peptide (TP) and Chinese pond turtle (Chinemys reevesii) peptide (TMP) on the intestinal mucosal immune system (IMIS). The results demonstrated that TP and TMP improved holistic immunity by restoring the vital immune organ atrophy and proliferation capacity of spleen immune cells. Moreover, TP and TMP significantly increased the serum content of IgA and cytokines that are responsible for immune cell activation and antigen clearance. TP and TMP promoted intestinal B cell activation, class switching recombination, and antibody secreting processes in a T cell-independent manner to increase the SIgA content. Furthermore, TP and TMP enhanced the intestinal barrier by increasing the protein expression of tight junctions (TJs) and adhesion junctions (AJs) and ameliorating the intestinal morphology. Mechanistically, TP and TMP activated the AHR/IL-22/STAT3/IL-6 axis to enhance the IgA response and improve the intestinal barrier, indicating their potential in intestinal health modulation.

S-scheme heterojunctions can offer an effective strategy for spatially separating photogenerated charge carriers, thereby sig F nificantly enhancing photocatalytic performance. In this study, cadmium sulfide (CdS)/copper tungstate (C F uWO 4 ) (CdS/CW) S-scheme heterojunction photocatalysts with adjustable components were fabricated by decorating CdS nanorods with CuWO 4 nanoparticles. The optimal hydrogen evolution rate (2725.91 μmol g –1 h –1 ) of CdS/CW-10% with excellent cycling stability under visible light is 10.1-fold higher than pure CdS. Density functional theory calculations and photoelectrochemical analyses confirmed that the S-scheme charge-transfer mechanism from CdS to CuWO 4 is responsible for the enhanced photocatalytic performance by promoting charge separation. Additionally, the photothermal effect of CuWO 4 increased the local temperature of the photocatalyst, further accelerating the reaction kinetics. This study highlights a dual-enhancement approach based on interfacial charge modulation by constructing an S-scheme heterojunction and photothermal activation, providing valuable insights into the design of high-efficiency S-scheme photocatalysts for solar-driven hydrogen production.

Nickel nanoparticles (Ni NPs) encapsulated in carbon shells have shown promise in the electrochemical reduction of CO 2 to CO. The electronic regulation of the interface between Ni NPs and carbon shells plays a crucial role in reducing the energy barrier of the CO reaction path. We report the formation of a catalyst with hierarchical porosity (Ni NPs@NC) using a high-surface-area 3D Ni-MOF as the precursor. By correlating the pyrolysis temperature with structural changes and catalytic efficiency, structure-activity relationships were established. Because of the confined encapsulation of the Ni NPs by the N-doped carbon layer, the framework does not collapse during pyrolysis but also produces a high-density of exposed Ni-N active sites and better mass transport paths. Notably, the Ni NPs@NC-800 sample had an outstanding electrocatalytic performance for CO 2 reduction, achieving a maximum Faradaic Efficiency (FE) of 93% at −0.8 V vs RHE, and maintaining over 90% efficiency even after 48 h of continuous operation. Raman spectroscopy showed that the interface between the Ni NPs and the carbon shell play a critical role in stabilizing the critical COOH intermediate, promoting CO desorption and inhibiting the competing hydrogen evolution reaction. This work may provide insight for producing catalysts for efficient electrochemical CO 2 reduction over a wide potential range.

In this paper, a novel hydroxyethylcellulose (HEC)-assisted carbon-coating method was developed to synthesize LiFePO 4 /C composites. The structure and morphological transformation of the as-prepared samples were studied using a combination of X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy. The particles of the samples obtained were more homogeneous than the reference sample prepared without the addition of HEC and the coated carbon were more uniformly distributed on the LiFePO4 surface. In addition, the HEC-assisted sample exhibited higher capacities and better rate capability in the charge-discharge test, and the charge transfer resistance calculated from the electrochemical impedance spectra data was smaller.

The transparent and thermal developments of high-purity Al 2 O 3 doped with different levels of Nd 2 O 3 were investigated. Dopant levels ranged from 500–1500 ppm (Nd/Al atomic ratio). The samples were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, transmittance spectroscopy and specific heat measurement. Results revealed that with proper Nd doped, Nd 3+ ions solid dissolved in Al 2 O 3 lattice, resulting in small and uniform grain and high bonding vibration, which was beneficial to transparent and thermal properties. With 1000 ppm Nd doped, Al 2 O 3 translucent ceramics showed a total transmittance of 89% and thermal conductivity of 41.7 W/m/K, indicating a potential application as substrate for effective heat dissipation and multi emitting surface in LEDs module.

A basic anion exchange resin , Amberlite IRA-900, was loaded with Pd(C 3 H 5 )(C 5 H 5 ) by an easy metal-organic chemical vapor deposition (MOCVD) approach to give Pd@IRA-900 catalyst after reduction at room temperature . Ultraviolet-Visible spectroscopy results showed a red shift of the absorption peak of Pd 2+ after the Pd precursor was loaded on the resin, indicating that a chemical reaction occurred between the precursor and the support. Pd nanoparticles with 2.6 nm of average size were well dispersed on the support. The Pd@IRA-900 catalyst showed high activity for different kinds of aryl halides in Suzuki-Miyaura coupling reactions under mild and aerobic conditions. Excellent recyclability of Pd@IRA-900 catalyst was also observed in the Suzuki-Miyaura coupling reaction of iodobenzene and phenylboronic acid . A bifunctional catalyst Pd@IRA-900(OH) was synthesized by pretreating the ion exchange resin support with NaOH before Pd loading, which successfully catalyzed the Suzuki-Miyaura reaction of iodobenzene and phenylboronic acid without base under aerobic conditions.

Photoactive WO 3 is attractive as a photocatalyst for green energy evolution through water splitting. In the present work, an electrochemical anodic oxidation method was used to fabricate a photo-responsive nanotube array-like WO 3 /W (NA-WO 3 /W) photoanode from W foil as a precursor. Compared with a reference commercial WO 3 /W electrode, the NA-WO 3 /W photoanode exhibited enhanced and stable photoelectrocatalytic (PEC) activity for visible-light-driven water splitting with a typical H 2 /O 2 stoichiometric ratio of 2:1 and quantum efficiency of approximately 5.23% under visible-light irradiation from a light-emitting diode ( λ = 420 nm, 15 mW/cm 2 ). The greatly enhanced PEC performance of the NA-WO 3 /Wphotoanode was attributed to its fast electron–hole separation rate, which resulted from the one-dimensional nanotube array-like structure, high crystallinity of monoclinic WO 3 , and strong interaction between WO 3 and W foil. This work paves the way to a facile route to prepare highly active photoelectrodes for solar light transfer to chemical energy .

The semi-molten smelting process of a mixture of saprolitic and limonitic laterite ores was systematically investigated and the effect of slag basicity was deeply analyzed. The results indicate that the slag system can be located in the liquidus region of low melting-point diopside (CaMgSi 2 O 6 ) when slag basicity is kept at 0.3 and limonitic laterite mass fraction is not less than 10%. When the reduction temperature, C/O mass ratio, limonitic laterite mass fraction and slag basicity are kept at the optimum values of 1300 °C, 0.86, 20% and 0.3, respectively, ferronickel products with grades 6.42% Ni and 86.99% Fe are prepared. The recovery rates of Ni and Fe reach 88.60% and 72.25%, respectively.

Direct synthesis of dimethyl carbonate (DMC) from CO 2 is critical for achieving carbon neutrality, yet the sluggish formation and conversion of the key *CH₃OCOO intermediate-due to the difficulty of C-O coupling-limit high DMC yields. Herein, we developed a boric acid-assisted recrystallization strategy to fabricate grain-boundary-rich CeO 2 hollow nanospheres, which serve as an efficient catalyst for CO 2 to DMC synthesis. The introduction of grain-boundary (GBs) induced the electron redistribution, which led a decrease in the electron density of bulk Ce ions and created a localized electron-rich region at homogeneous interface. This unique electronic landscape promoted reactive methoxy formation and stronger CO 2 adsorption, thereby enabling more efficient coupling of *CH 3 O and *CO 2 to form the *CH 3 OCOO. Concurrently, the enhanced CO 2 adsorption facilitated the dissociation of *CH 3 OCOO and subsequent DMC formation. As a result, the 4%BCeO 2 -GBs achieved an advantageous DMC yield of 19.8 mmol/g. In the assistance of dehydrating agent, the catalyst delivered a remarkable 264.2 mmol/g DMC yield and 7.12% methanol conversion, which was 32 times higher than commercial CeO 2 . This study elucidated the intrinsic mechanisms governing *CH 3 OCOO intermediate behavior and offers valuable guidance for CO 2 converting into high-value organic chemicals.
