Plants have a limited ability to absorb green light. Additionally, the energy distribution of sunlight in the deep-red region is weak. These factors restrict the efficiency of plant growth and limit yield improvements. In this study, a novel deep-red phosphor material, KAl₁₁O₁₇: Cr³⁺, was designed and synthesized through a high-temperature solid-state method. This material exhibits deep-red light emission at a central wavelength of 697 nm under broadband excitation at 430 nm (near-ultraviolet) and 562 nm (green light). By leveraging a "light-cutting" mechanism, the phosphor converts underutilized green light into far-red light, which strongly aligns with the absorption peak of the plant photoreceptor P FR state. When applied as a thin-film coating, the material significantly enhances lettuce growth under controlled green-light irradiation. These findings demonstrate the potential of KAl₁₁O₁₇: Cr³⁺ in optimizing spectral distribution for energy-efficient agricultural lighting systems.

Graphical Due to the Sb- and O-cosubstitution , the Li 10 SnP 1.84 Sb 0.16 S 11.6 O 0.4 sulfide electrolyte with high ionic conductivity, broad electrochemical window, and high air stability was prepared for high-performance all-solid-state battery. Electrochemical measurement and postmortem analysis of cycled electrodes results revealed that the mechanism of improving cell stability is the inhibition of electrolyte side reaction in the cathode. Sb- and O-cosubstituted sulfide electrolyte was demonstrated to be a promising solid electrolyte for practical all-solid-state battery. The development of solid-state electrolytes with high ionic conductivity, broad electrochemical stability, and high air stability is the key to realizing the practical application of all-solid-state batteries. Herein, Sb- and O-cosubstituted Li 10 SnP 2 S 12 sulfide electrolytes are prepared for the first time. An appropriate amount of Sb and O substitution provides the optimized Li 10 SnP 1.84 Sb 0.16 S 11.6 O 0.4 electrolyte with the highest ionic conductivity of 2.58 mS ⋅ cm −1 at RT. Furthermore, the cyclic voltammetry analysis results demonstrate that the Li 10 SnP 1.84 Sb 0.16 S 11.6 O 0.4 electrolyte displays a broader electrochemical window of 1.4–5.0 V vs. Li + /Li than that of 1.7–2.4 V vs. Li + /Li for the nonsubstituted Li 10 SnP 2 S 12 . Moreover, benefitting from the soft acid Sb 5+ and hard base O 2− dual substitution, the air stability of electrolyte has been improved. Furthermore, the LiNbO 3 @LiCoO 2 /Li−In cell assembled with the Li 10 SnP 1.84 Sb 0.16 S 11.6 O 0.4 electrolytes exhibits a high initial discharge specific capacity of 124.7 mAh ⋅ g −1 at 0.05 C and maintains 85 % capacity retention after 200 cycles at 0.5 C and 25 °C, which is much higher than that of the cell assembled with the Li 10 SnP 2 S 12 electrolytes. XPS measurement results revealed that the mechanism of improving cell stability is the inhibition of electrolyte side reaction in the cathode. Sb- and O-cosubstituted Li 10 SnP 2 S 12 was demonstrated to be a promising solid electrolyte for practical all-solid-state batteries.

A new non-centrosymmetric silicate Ba5Y12Zn[O(SiO4)]8 (BYZSO), the first compound of the Ba–Y–Zn–Si–O system, was synthesized by a high-temperature solution method in an open system, and its structure was identified using single-crystal X-ray diffraction data. Structural analysis indicates that it crystallizes in the noncentrosymmetric space group I2m (no. 121) with lattice parameters a = 18.7014(6) Å and c = 5.3640(2) Å corresponding to a tetragonal crystal system and is composed of isolated [ZnSi4O16] and [SiO4] units. Meanwhile, the effect of the cation-to-silicon ratio on the Si–O framework was also studied by investigating the structures of barium-, yttrium-, and zinc-containing silicates found in the Inorganic Crystal Structure Database (ICSD). Experimental characterization demonstrates that it possesses a short ultraviolet cut-off edge of 204 nm (6.18 eV), a moderate second harmonic generation (SHG) response (0.3× KDP) at the maximum particle size, and excellent thermal stability. Besides, first-principles theoretical calculations were carried out to elucidate the relationship between the electronic structure and optical properties. In summary, this work is instructive for the synthesis and design of silicates with different dimensions in the Ba–Y–Zn–Si–O system.

The hydrogenolysis of cellulose-derived 5-hydroxymethylfurfural is essential for the production of fuels and chemicals from biomass. Herein, we fabricated a phosphorus-doped Pd/P-TiO2 catalyst for the hydrodeoxygenation of 5-hydroxymethylfurfural to 2,5-dimethylfuran. A large number of defects and electron-deficient Ti4+ sites (dTi4+) were formed by doping phosphorus into the TiO2 support, which could promote hydrogen spillover and reactant adsorption. Moreover, the spilled active hydrogen induced the formation of P–O(H)-dTi4+, which acted as a “Brønsted acidic site” to promote the activation of C–O bonds. Consequently, the Pd/P-TiO2 catalyst exhibited superb activity for the hydrodeoxygenation of 5-hydroxymethylfurfural to 2,5-dimethylfuran at mild conditions of 150 °C under 1 MPa H2.

The mixed phosphate Na₄Fe₃(PO₄)₂(P₂O₇) (NFPP) via synergistic coordination of mixed [PO₄]/[P₂O₇] anion groups achieves a flat voltage plateau at 3.2 V (vs. Na + /Na) and a theoretical specific capacity of 129 mAh g −1 , but its practical application is still limited by its inherent low electronic conductivity. Through structural integration of polyanion-type cathode materials, this study innovatively designed and constructed hierarchical Na₄Fe₃(PO₄)₂(P₂O₇)@C mesoporous microspheres (NFPP@CMMS). The NFPP nanocrystals uniformly embedded in a three-dimensional interconnected meso porous carbon matrix (pore size distribution: 2–5 nm). Such hierarchical meso/micro-nano architectures provided expansive ion-exchange interfaces, accelerating Na + de/intercalation kinetics while enhancing electronic conductivity and mitigating structural collapse during cycling. Consequently, the NFPP@CMMS delivers exceptional reversible discharge capacity (121 mAh g −1 at 0.1C), outstanding rate capability (72 mAh g −1 at 50C), and superior cycling stability (90.70 % capacity retention after 3500 cycles at 5C). This triple-synergy strategy—combining nano-confinement effects, interconnected mesoporous channels, and carbon-encapsulated network—provides a novel pathway for developing practical sodium-ion battery cathodes.

In this study, a series of Ni-CeO 2 /TS-1 (Titanium Silicalite-1) catalysts were synthesized for dry reforming of methane (DRM). Among them, 5Ni-10CeO 2 /TS-1 exhibited the highest catalytic performance with 89 % CH 4 and 93 % CO 2 conversions, 4.81 mol CH4 ·g Ni -1 ·h −1 and 4.99 mol CO2 ·g Ni -1 ·h −1 specific activities, 95.5 % H 2 /CO ratio after 50 h, accompanied by the good stability with 2.9 % CH 4 and 2.3 % CO 2 activity loss within 100 h. Combined with various characterizations, the structure–function relationship was also investigated. For the physical and morphological analysis, it was indicated that the appropriate CeO 2 content could effectively diminish, disperse the Ni nanoparticles, and maintain MFI backbone structure. For the electronic structure, the introduced CeO 2 could improve the amount and strength of the surface Ni-O-X (Ti or Ce) species by changing the interaction among Ni nanoparticles, TS-1 and CeO 2 . It led to more Ni nanoparticles in stronger electron-deficient state, as well as more medium-strength basic sites, favoring for the activation of CH 4 and CO 2 . However, Ni nanoparticles would be covered when excessive CeO 2 was introduced, preventing the exposure of the active sites. Therefore, only the suitable CeO 2 in the catalysts could significantly improve catalytic performance for DRM with long-term stability. Furthermore, the good anti-sintering and anti-coking properties of 5Ni-10CeO 2 /TS-1 were mainly dependent on the optimal amount of surface Ni-O-X species with high strength. In-situ DRIFTS (diffuse reflectance infrared spectroscopy) analysis demonstrated that the introduced CeO 2 could help catalyst favor for activating CH 4 and CO 2 molecules, and inhibiting the CH 4 overcracking and carbon accumulation, confirmed by the long-term measurement and structure analysis of spent catalysts.

Vaccinium dunalianumleaf buds make one of the most commonly used herbal teas of the Yi people in China, which is used to treat articular rheumatism, relax tendons, and stimulates blood circulation in the body. In addition, 6′-O-caffeoylarbutin (CA) is a standardized extract ofV. dunalianum, which has been found in dried leaf buds, reaching levels of up to 31.76%. Because of the uncommon phenomenon, it is suggested that CA may have a potential therapeutic role in hyperlipidemia and thrombosis. This study was designed to study the efficacy of CA on treating hyperlipidemia and thrombosis and the possible mechanisms behind these effects. Hyperlipidemia and thrombosis zebrafish models were treated with CA to observe variations of the integrated optical density within the vessels and the intensity of erythrocyte staining within the hearts. The possible mechanisms were explored using network pharmacology and molecular docking. The results demonstrate that CA exhibits an excellent hypolipidemic effect on zebrafish at concentrations ranging from 3.0 to 30.0 μg/mL and shows thrombosis inhibitory activity in zebrafish at a concentration of 30.0 μg/mL, with an inhibition rate of 44%. Moreover, network pharmacological research shows that MMP9, RELA, MMP2, PRKCA, HSP90AA1, and APP are major targets of CA for therapy of hyperlipidemia and thrombosis, and may relate to pathways in cancer, chemical carcinogenesis-receptor activation, estrogen signaling pathway, and the AGE–RAGE signaling pathway in diabetic complications.

Hepatocellular carcinoma (HCC) is a major cause of cancer-related deaths globally, and the need for effective systemic therapies for HCC is urgent. Our previous work reveals that Pin1 is a potential anti-HCC target, which regulates miRNA biogenesis and identifies API-1 as a novel Pin1 inhibitor to suppresses HCC. However, a great demand in HCC therapy as well as the limited chemical stability and pharmacokinetic feature of API-1 motivated us to find improved Pin1 inhibitors. Herein, we designed and synthesized diverse 6-O-benzylguanine derivatives and discovered API-32 as a novel Pin1 inhibitor with better stability and pharmacokinetic property over API-1. API-32 directly interacted with the Pin1 PPIase domain to inhibit Pin1 activity. API-32 significantly suppressed the cell proliferation and migration of HCC cells by blocking Pin1’s downstream signal. Moreover, API-32 exhibited an enhanced inhibitory function against the HCC tumor in mice models without obvious toxicity, making it a promising drug candidate for HCC treatment.

Alzheimer’s disease, a progressive neurodegenerative disorder of the central nervous system, presents a complex pathological mechanism that limits the efficacy of conventional single-target drugs. Utilizing the unique advantages of natural products in multi-target intervention, this study employed the active component 1- O -acetylbritannilactone (ABL) from Inula britannica L. as the parent structure. Guided by the multi-target directed ligands (MTDLs) strategy, four novel derivatives (ABL-1 to ABL-4) were successfully designed and synthesized by introducing acetylcholinesterase (AChE) inhibitory pharmacophores into the ABL scaffold. In vitro pharmacological evaluation demonstrated that ABL-2, ABL-3, and ABL-4 not only preserved the anti-neuroinflammatory activity of the parent compound but also endowed compound ABL with AChE inhibitory potency. Notably, ABL-4 displayed the most promising dual efficacy profile, achieving an AChE inhibition rate of 40.09 ± 0.73 % at 30 μM and an anti-neuroinflammatory activity (EC 50 = 8.43 ± 0.5 μM). Molecular docking simulations revealed that the dual-target synergistic mechanism of ABL derivatives arises from hydrogen bonding and π-π stacking interactions with key residues of both AChE and inducible nitric oxide synthase (iNOS). This work not only validates the feasibility of the MTDLs strategy in optimizing natural product scaffolds but also provides a structurally novel lead compound with significant potential for developing multi-target anti-AD therapeutics.

Xanthine oxidase (XOD) inhibition has long been considered an effective anti-hyperuricemia strategy. To identify effective natural XOD inhibitors with little side effects, we performed a XOD inhibitory assay-coupled isolation of compounds fromSmilacis Glabrae Rhizoma(SGR), a traditional Chinese medicine frequently prescribed as anti-hyperuricemia agent for centuries. Through the in vitro XOD inhibitory assay, we obtained a novel XOD inhibitor, 5-O-caffeoylshikimic acid (#1, 5OCSA) with IC50of 13.96 μM, as well as two known XOD inhibitors, quercetin (#3) and astilbin (#6). Meanwhile, we performed in silico molecular docking and found 5OCSA could interact with the active sites of XOD (PDB ID: 3NVY) with a binding energy of −8.6 kcal/mol, suggesting 5OCSA inhibits XOD by binding with its active site. To evaluate the in vivo effects on XOD, we generated a hyperuricemia mice model by intraperitoneal injection of potassium oxonate (300 mg/kg) and oral gavage of hypoxanthine (500 mg/kg) for 7 days. 5OCSA could inhibit both hepatic and serum XOD in vivo, together with an improvement of histological and multiple serological parameters in kidney injury and HUA. Collectively, our results suggested that 5OCSA may be developed into a safe and effective XOD inhibitor based on in vitro, in silico and in vivo evidence.Keywords:Smilacis Glabrae Rhizoma;5-O-caffeoylshikimic acid;potassium oxonate;hyperuricemia;XOD inhibitor

Efficient separation of water-in-oil (W/O) emulsions is essential for wastewater treatment, yet conventional electrospun membranes often suffer from poor mechanical properties, large inter-fiber pores and structural instability. Here, we propose a coaxial electrospinning strategy that combines a PVDF/CNC core with a PDMS shell to construct a hierarchical superhydrophobic membrane. The incorporation of CNC induces nonsolvent-driven microphase separation during electrospinning, generating spindle- and nanosphere-like surface structures while reinforcing the fibrous network. Meanwhile, the PDMS shell contributes to inter-fiber connectivity and enhances surface hydrophobicity. These synergistic effects result in an interlocked porous architecture that supports gravity-driven separation of W/O emulsions. At 4 wt% CNC, the membrane achieves a water contact angle of 158°, an average pore size of 1.93 μm and a flux of 2890 L m −2 h −1 , while maintaining over 94 % separation efficiency over 20 cycles. This work provides a sustainable strategy for tailoring structures for effective W/O emulsion separation.

Mercury ions (Hg 2+ ) are categorized as environmental pollutants, which distributed in water, soil, and food systems due to environmental contamination. Hence, designing a sensitive assay for the convenient determination of Hg 2+ is of great importance. Herein, S and O-doped graphite phase nitrogenized carbon quantum dots (S, O-C 3 N 4 QDs) was encapsulated within a europium -based metal-organic framework (Eu-MOF) to construct a novel ratiometric fluorescent nanoprobe for the quantitative detection of Hg 2+ . The native emission of S, O-C 3 N 4 QDs at 445 nm is used as a response signal, while Eu-MOF with fluorescence offers a reference signal at 619 nm. Hg 2+ exhibits high affinity for the surface functional groups of S/O-C 3 N 4 QDs, forming non-fluorescent chelation complexes that induce static quenching. This results in significant attenuation of the fluorescence intensity at 445 nm, while the emission at 619 nm remains invariant. A ratiometric fluorescence sensing platform was established based on the intensity ratio (F 445 /F 619 ) for the selective detection of Hg 2+ . The linear range of S, O-C 3 N 4 QDs/Eu-MOF of Hg 2+ was 0.25–35 µM and with a detection limit of 4.3 nM. The satisfying results demonstrate the effectiveness of the developed S, O-C 3 N 4 QDs/Eu-MOF-based fluorescence probe for Hg 2+ detection, highlighting its promising potential for environmental monitoring applications.
