Compared with other fluorescent crystal phases, garnet has better structural stability in a glass matrix and renders precisely controllable emissions due to the abundant lattice control positions. In this work, we regulate the coordination field of Ce 3+ ion based on the co-substitution method and achieve the spectra regulation in the yellow–green range. We used Ba 2+ –Si 4+ cations to replace Y 3+ –Al 3+ cations in Y 3 Al 5 O 12 (YAG) matrix to obtain blue-shift of the emission peak from 552 to 539 nm. The centroid shift and crystal field splitting decrease with the decreasing covalency of the bond between the Ce 3+ ion and the surrounding anions owing to the higher electronegativity of Si 4+ ions than Al 3+ ions. The corresponding fluorescent films were prepared by a low-temperature co-sintering process based on the as-made Ba 2+ –Si 4+ co-substituted phosphor. X-ray powder diffractometer and scanning electron microscopy images showed that the fluorescence crystals were less eroded and evenly dispersed in the glass matrix. Spectral analysis showed that the garnet phase was protected by using lead-free borosilicate glass with a low melting point, and the quantum efficiency of phosphor-in-glass (PiG) retains 98% of the corresponding phosphor. By adjusting the ratio of garnet phosphor to commercial red nitride phosphors, a warm white fluorescence with a color rendering index of 80.3 and color temperature of 3899 K was obtained. The prepared warm white film has potential application value in the whole spectra field.

The reactions of a semirigid carboxylic ligand 5-(Pyridin-3-yl)isophthalic acid(H 2 pyip) with Mn(CH 3 COO) 2 /Zn(NO 3 ) 2 /Pb(NO 3 ) 2 afforded three new complexes: [Mn(pyip)(H 2 O) 2 ] n ( 1 ), [Zn(pyip)(H 2 O) 2 ] n ( 2 ), and [Pb(pyip)] n ( 3 ). Their structures have been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses, IR spectra, powder X-ray diffraction (PXRD), and thermogravimetric (TG) analyses. X-ray structure analysis reveals that complexes 1-2 showed identical 3D supramolecular architecture that just connect different metal centers. They all crystallize in hexagonal space group P6(5) and exhibit the same coordination mode. One of the H 2 pyip adopts bidentate chelate coordination mode, and the other coordinate carboxylate oxygen atom adopts the single dentate-bridging mode. Complex 3 adopts different coordination modes crystallized in monoclinic space group P2(1)/c compared to 1-2, combined bidentate chelate and chelating–bridging tetradentate coordination modes. A noticeable point in this paper is that compounds 1-3 exhibit preferable catalytic properties on degradation of Rhodamine B (RhB). Moreover, the luminescent properties were investigated.

The recently discovered Na 3 MnTi(PO 4 ) 3 cathode material has an extremely high theoretical capacity, but its poor cycling performance makes it challenging to apply. In this work, a series of NASICON-type Na 3+x MnV x Ti 1-x (PO 4 ) 3 /C (x = 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.8, 1) cathode materials were prepared by sol-gel method for sodium-ion batteries. X-ray diffraction (XRD) indicates that vanadium doping has increased the cell spacing within the material and the cell volume. From the results of X-ray photoelectron spectroscopy (XPS) and Energy dispersive X-ray spectroscopy (EDS) mapping images, it is shown that vanadium has been successfully doped into the material. Among them, the Na 3·3 MnV 0·3 Ti 0·7 (PO 4 ) 3 /C delivers an outstanding specific capacity (121.7 mAh g −1 at 0.1C, C = 135 mA g −1 ) and Na 3·4 MnV 0·4 Ti 0·6 (PO 4 ) 3 /C shows an excellent capacity retention (80.88 % after 1500 cycles at 1C). Notably, the coulombic efficiency of both materials during cycling is close to 100 %, indicating that these materials have great practical application value.

Garnet-type Li 7 La 3 Zr 2 O 12 (LLZO) ceramics has been considered as an ideal solid-state electrolyte for Li metal cells because of its high ionic conductivity and relatively stable interface with Li. However, it is electrochemically incompatible with some high-voltage cathodes, e.g. LiCoO 2 . In this work, a nanoscale Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) fast ion conductor was coated on LiCoO 2 (only 1 wt% LATP), bringing obviously enhanced interfacial compatibility with a composite electrolyte composed of Al, Nb-codoped LLZO and polyethylene oxide (PEO). A free-standing, flexible and ultrathin (20 μm) electrolyte membrane was successfully fabricated by a facile and scalable route, even though with a high ceramics content (67 wt%). Quasi-solid-state coin and pouch-type Li cells were assembled with the LATP-coated LiCoO 2 cathode, free-standing composite electrolyte and Li anode, together with soft interface modification by in-situ polymerization. The cells show stable cycling due to combined factors of enhanced electrode/electrolyte compatibility, ultrathin nature of the electrolyte membrane and the in-situ built soft interface. The pouch cells can be cycled for 300 cycles at 0.3 C and 60 °C with 80% retention. The pouch cells can endure abuse tests of bending, cutting and nail penetration. At a practical LiCoO 2 loading of 3 mAh cm −2 , the Li|LiCoO 2 pouch cell still shows stable cycling with 90% retention after 100 cycles at 60 °C (0.2 C charge/0.5 C discharge). This work provides a practical method to fabricate high-performance solid-state Li cells.

The Na 5 Tm 1 − x (Y 1/3 Yb 2/3 ) x (MoO 4 ) 4 ceramics (x=0-0.18) were successfully synthesized via the solid-state reaction method. XRD analysis revealed that they possessed a single-phase tetragonal scheelite structure belonging to the space group I4₁/a(88). SEM analysis demonstrated that the samples sintered at 600 °C exhibited a dense microstructure, with a relative density as high as 94.9% and an average grain size ranging from 2.172 μm to 2.424 μm. The relative density serves as an external factor influencing ε r and Q×f, while τ f is related to bond valence. The ionicity of the Tm-O bond, and the lattice energy and bond energy of the Mo-O bond are the intrinsic factors determining ε r , Q×f, and τ f , respectively. Raman spectroscopy provided an intuitive characterization of the vibrational properties of the [MoO 4 ] 2− tetrahedra within the ceramics. Although the pure phase Na₅Tm(MoO 4 ) 4 ceramic exhibited optimal dielectric properties (ε r =8.025, Q×f=18,967 GHz, and τ f = -101 ppm/°C) at 625 °C, the Na 5 Tm 0.91 Y 0.03 Yb 0.06 (MoO 4 ) 4 ceramic sintered at 600 °C demonstrated superior dielectric properties (ε r =7.82, Q×f=34,752 GHz, and τ f = -71.9 ppm/°C).

Sodium superionic conductor (NASICON)-type phosphates cathodes have attracted considerable attention due to their high operational voltage and robust three-dimensional (3D) framework; however, the poor intrinsic electronic conductivity and low energy density hinder their broader application. Herein, a novel NASICON-type Na 3 V 1.44 Fe 0.5 Mo 0.06 (PO 4 ) 3 cathode was designed through Fe/Mo dual-doping at the V sites of Na 3 V 2 (PO 4 ) 3 and synthesized via a conventional high-temperature solid-state method. The introduction of Fe 3+ activates the V 4+ /V 5+ redox couple at a high voltage plateau (∼ 4.0 V), while also generates additional Fe 2+ /Fe 3+ and V 4+ /V 5+ redox pairs. Meanwhile, the doing of Mo 6+ creates cation vacancies, effectively modulating the electronic structure of vanadium and promoting ionic transport kinetics. Benefiting from this dual-doping strategy, the Na 3 V 1.44 Fe 0.5 Mo 0.06 (PO 4 ) 3 cathode delivers a high capacity of 123.4 mAh g −1 at 0.2C and an impressive energy density of 406 Wh kg −1 within 2.2–4.2 V. Moreover, it exhibits outstanding cycling stability, presenting a capacity retention of 92 % after 2500 cycles at 30C. This work highlights a viable strategy for advancing high-performance NASICON-type cathodes through complex metal ion doping.

In late-stage type 2 diabetes mellitus (T2DM), impaired islet β cell function leads to absolute insulin deficiency, thereby disrupting blood glucose homeostasis. GLP-1, an incretin hormone, stimulates insulin secretion from islet β cells post-meals. This study investigated the effects of anthocyanin cyanidin-3-O-glucoside (C3G) on GLP-1 secretion using STC-1 (intestinal endocrine L cells) and NIT-1 (islet β cells). In a co-culture system, C3G treatment increased GLP-1 secretion in STC-1 cells, promoting insulin release in NIT-1 cells under high glucose. Mechanistically, C3G activated the PPARβ/δ-β-catenin-TCF-4 pathway in STC-1 cells, enhancing PG precursor transcription and GLP-1 synthesis.Inhibiting PPARβ/δ with GSK0660 blocked this C3G-induced upregulation. Overall, C3G stimulates GLP-1 secretion from intestinal L cells via this pathway, indirectly boosting insulin release from β cells. These findings enhance T2DM mechanism understanding and suggest the potential of C3G in GLP-1-based T2DM therapy.

BACKGROUND Phytohormones regulate plant growth, development, and stress responses. Strigolactones are a class of phytohormones that have attracted significant scientific interest because of their multifunctional roles in plant biology and ecological interactions. RESULTS In this study, 34 strigolactone mimics were efficiently synthesized by substituting pre-synthesized 5-chloro-3-methylfuran-2(5 H )-one with phenolics and benzenethiols. Most of the chemicals showed seed germination-promoting activities on corn, sorghum, soybean, and sunflower seeds. At a concentration of 100 mg/L, 3 s and 4 h showed a promotion rate of 56% and 63% on corn bud growth and 50% and 62% on sorghum root growth, respectively. The promotion rates of 3 s and 4 h on corn, sorghum, soybean, and sunflower root growth ranged between 35–48% and 46–71%, respectively. The effect on germination of the target compound exhibited a dose-dependent trend, increasing within the range of 0.01–10 mg/L and decreasing within the range of 10–100 mg/L. Optimal promotion rates for corn root and shoot growth at 3 s and 4 h were achieved at a concentration of 10 mg/L. 3 s and 4 h regulated the content of the abscisic acid, auxin, cytokinin, and gibberellin to promote plant germination. The binding energy of GR24 docking with strigolactone receptor proteins derived from Arabidopsis (AtD14) was −7.30 kcal/mol, while 3 s and 4 h were −7.96 and −8.05 kcal/mol, respectively. CONCLUSIONS The structure–activity relationships of 34 novel strigolactone mimics and docking simulations provided structural optimization strategies for designing new strigolactone mimics as plant growth regulators. © 2025 Society of Chemical Industry.

Fatty liver hemorrhagic syndrome (FLHS) has become a common and serious disease in intensive laying hen farming, seriously endangering the productivity and health of laying hens. Although probiotics have been recognized as an emerging candidate therapeutic strategy for liver disease, their effective substances and mechanisms for alleviating FLHS remain to be elucidated. In this study, corticosterone (Cort) was applied to induce FLHS in laying hens, and Lactobacillus plantarum ( L. plantarum 1–2-3) was used for the intervention. The results showed that L. plantarum 1–2-3 treatment significantly ameliorated Cort-induced hepatic steatosis and liver damage in laying hens, as evidenced by decreased levels of triglyceride (TG), total cholesterol (TC), aspartate aminotransferase, and alanine aminotransferase. Importantly, we found that L. plantarum 1–2-3 could biosynthesize gamma-aminobutyric acid (GABA) by expressing glutamic acid decarboxylase. Surprisingly, feeding GABA to laying hens replicated the effect of L. plantarum 1–2-3 in alleviating Cort-induced FLHS. GABA significantly down-regulated the mRNA expression of Acc , Fasn , Cd36 , and Gpam while upregulating the levels of Ppara and Cpt1a . An in vitro verification study showed that GABA decreased TG and TC content in Leghorn male hepatoma cells. Moreover, GABA significantly enhanced antioxidant enzyme activity, inhibited oxidative stress in hepatocytes, regulated the AMPK/NLRP3 signaling pathway, and reduced the protein expression of NF-κB, TNFα, and IL-1β. In conclusion, our study demonstrated that L. plantarum 1–2-3 could effectively alleviate FLHS in laying hens, while GABA was an important postbiotic for L. plantarum 1–2-3 to exert lipid-lowering and anti-inflammatory effects.

The rising demand for cost-effective and safe energy storage systems has ignited strong global interest in advanced cathodes that surpass lithium-ion batteries in practical applications. Herein, we propose a composite material in which five ions, Ti 4+ , Mn 2+ , Fe 2+ , Zr 4+ , and Mo 6+ , are doped into the lattice of Na 3 V 2 (PO 4 ) 3 and a uniform carbon-coating layer is applied to its surface, resulting in the formation of high-entropy doped Na 3 V 2 (PO 4 ) 3 @C materials (HENVP@C). When employed as the cathode material for Sodium-ion batteries (SIBs) and hybrid lithium/sodium-ion batteries (HLSIBs), HENVP@C shows remarkable Li + /Na + storage capabilities. The results of electrochemical performance tests on half-cells reveal that HENVP@C exhibits a high capacity, along with excellent cycle life and stability. High-entropy doping effectively stabilizes the NASICON structure of HENVP@C, enhances ionic conductivity, and optimizes ion diffusion kinetics, particularly improving its dual-ion pseudocapacitive storage capability. In addition, the surface carbon coating improves the electronic conductivity of the material. The insights presented in this work provide new ideas for designing cathode materials for SIBs and HLSIBs.

In this study, we developed a synergistic modulation strategy through in situ dual-anion/cation doping coupled with vacancy engineering, demonstrating a direct ammonia etching approach to synthesize Cu/S-In(OH) 3 with controlled indium vacancies (V In ) from CuInS 2 precursors. This in situ doping approach provides a uniform distribution of Cu cations and S anions throughout the material, overcoming conventional doping heterogeneity. Simultaneously, an indium vacancy (V In ) structure was precisely engineered and regulated through a growth limitation strategy. The synergistic interplay between the uniformly dispersed anions, cations and V In significantly suppresses the recombination of photogenerated carrier within In(OH) 3 , thereby allowing more carriers to participate in the surface catalytic reaction. Both experimental and theoretical analyses demonstrate that the introduction of V In into the defective states leads to a direct reduction in the band gap, significantly improving photocatalytic hydrogen evolution performance. The optimized Cu/S-In(OH) 3 with V In achieves a photocatalytic hydrogen production rate of 1.22 mmol g −1 h −1 , approximately 122 times higher than that of pure In(OH) 3 (0.01 mmol g −1 h −1 ). This work establishes a paradigm of integrating in situ doping and vacancy engineering strategies to rationally design In(OH) 3 -based materials, offering generalizable principles for advanced catalytic applications.
