Gadolinium gallium garnet has been emerging as a starlet for preparing efficient luminescent materials, while via crystal field engineering the luminescence properties of rare-earth activator in its solid solution phosphors were scarcely explored. In this work, Er 3+ -doped Gd 3 Zn x Ga 5-2x Ge x O 12 (GZG 5- 2x G:Er 3+ ) solid solutions were prepared by high-temperature solid-state reaction, where a hetero-valent co-substitution strategy was implemented via introducing Zn 2+ /Ge 4+ pair to replace 2 Ga 3+ sites. X-ray diffraction Rietveld refinements confirm all samples crystallized into pure garnet phase. Upon 381 nm excitation, Er 3+ concentration was spectrally optimized to be about 10%, substituting the Gd 3+ sites, and via the Zn 2+ /Ge 4+ co-substitution, luminescence intensity of GZG 2 G:10%Er 3+ increases by more than 3 times in comparison with that of the baseline GZGG:10%Er 3+ sample. All the GZG 5-2x G:10%Er 3+ solid solution samples color in bright green under illumination using an ultraviolet ~ 365 nm lamp.Thermometric properties of Er 3+ 2 H 11/2 -4 S 3/2 thermally coupled levels of were systematically studied on basis of fluorescence intensity ratio principle. The GZG 5-2x G:10%Er 3+ all can perform temperature sensing over a wide temperature range of 298-573 K with a maximum relative sensitivity (S r ) above 1.20% K -1 and an applicable minimum temperature resolution (δT) around 0.4 K. Continuous exploration of solid solution-manipulating luminescent properties would develop novel thermometry probes (particularly for activator with spin-allowed transitions) with higher S r and smaller δT for practical optical temperature sensing.

The high cost of conventional titanium feedstocks has severely constrained the industrial application of Ti–Al-based MAX-phase composites. This work presents a clean, cost-effective pathway for synthesizing Ti 4 Al(C, N) 3 /Al 2 O 3 composites directly from natural ilmenite concentrate. The synthesis encompasses two sequential stages: (i) the reduction and carbonitridation of pre-oxidized ilmenite in a hydrogen-rich atmosphere to yield a Ti(C, N, O) precursor, and (ii) pressureless sintering of the precursor with Al and Ti powders, followed by acid leaching to remove intermetallic byproducts. Through systematic parametric optimization, the precursor synthesis was established at 1150 °C for 70 min in a 4 vol pct CH 4 –80 vol pct H 2 –16 vol pct N 2 atmosphere, achieving a carbonitridation ratio exceeding 90 pct while suppressing detrimental carbon deposition. Subsequent pressureless sintering at 1500 °C for 4 h with a molar ratio of 2.2Ti(C, N, O):2Al:1Ti yielded the target composite. Mechanistic investigation, combining experimental characterization and density functional theory (DFT) calculations, reveals that the Al 3 Ti intermediate phase plays a dual critical role: it promotes deep deoxygenation of Ti(C, N, O) with in situ formation of Al 2 O 3 reinforcements, while simultaneously healing N vacancies in the MAX-phase lattice. Aberration-corrected transmission electron microscopy (AC-TEM) confirmed that the synthesized Ti 4 Al(C, N) 3 solid solution possesses a pristine hexagonal structure identical to that of phase-pure Ti 4 AlN 3 , with no observable lattice distortion or extended defects. This work presents a novel strategy for the economical and sustainable synthesis of high-performance Ti 4 Al(C, N) 3 /Al 2 O 3 composites.

Cyanidin-3- O -glucoside (C3G), a promising flavonoid with diverse biological properties, faces challenges in functional food application due to instability under various conditions. Therefore, this study aimed to develop a novel gum Arabic-coated nano-nutriosome (GA-C3G-NU) for promoting gastro-intestinal (GI) delivery of C3G and fortification of set-type yogurt (Ygr). The GI digestion study revealed that GA improved the stability of C3G-NU. After freeze-drying, FZD GA-C3G-NU maintained their nanosized, exhibited high encapsulation efficiency ≥90%, and an acceptable PDI ≤0.30. SEM analysis revealed crystal-like structure in GA-C3G-NU, while the XRD study confirmed their decreased crystallinity. Furthermore, the FZD GA-C3G-NU showed significantly controlled release profile ( p < 0.05) of C3G. The GA-C3G-NU didn't negatively affect the yogurt's properties. It maintained the desirable acidity while enhancing water holding capacity, color, texture, microstructure, and compatibility with lactic acid bacteria. Overall, GA-C3G-NU could be a promising carrier for enhancing C3G's gastrointestinal delivery, with potential use in dairy products.

This study developed an innovative colorimetric film by incorporating 1-butyl-3-methylimidazolium chloride (BmimCl) in a composite matrix containing red cabbage anthocyanins extract (RCAE), ferulic acid (FA), gellan gum (GG), and potato starch (PS) for real-time grass carp freshness detection. A comprehensive analysis was conducted on the rheological characteristics of film-forming solutions, mechanical properties, hydrophobicity, opacity, characterization of structure, sensitivity, and color stability of smart film. Significantly, the introduction of BmimCl led to multifaceted enhancements in film performance. The findings indicated that the flexibility of films added with BmimCl was enhanced and the elongation at break (EAB) was increased from 20.34 % to 28.36 %. The surface of films was smoother and denser, and the surface roughness was reduced from 1.7 μm to 1.2 μm. The peak intensities of the XRD and FT-IR patterns of films changed, indicating the formation of hydrogen bonds between BmimCl and film substrates. The GGPS-R-FA-B4 film presented the most pronounced color change in different pH environments and the most sensitive response to the variation of ammonia concentration in the environment. The color of GGPS-R-FA-B4 film exhibited a strong correlation with the quality change of fish, which could be used to distinguish the freshness, sub-freshness, and spoilage of grass carp. This study provided an effective method to enhance the accuracy and sensitivity of smart films for monitoring food freshness.

Acetaminophen (APAP) overdose causes acute liver injury (ALI) by triggering regulated hepatocyte death. While Imperata cylindrica (Imperatae Rhizoma) (IR) is used in traditional medicine for its hepatoprotective effects, its active compounds and their capacity to modulate this pyroptotic switch remain unknown. In the present study, friedelin (FRI) and 6-methoxyflavone (6-METH) were identified as the principal active compounds of IR, and their protective effects against APAP-induced ALI were evaluated in vivo and in vitro. The results showed that both FRI and 6-METH significantly ameliorated APAP-induced liver injury and reduced hepatocyte death. Mechanistically, their hepatoprotective effects were associated with AKT1-dependent activation of the PI3K/AKT pathway, accompanied by suppression of Caspase-3/ Gasdermin E (GSDME) signaling and attenuation of apoptosis and pyroptosis. Moreover, pharmacological inhibition or genetic silencing of AKT1 markedly weakened these protective effects. Taken together, these findings suggest that FRI and 6-METH are major hepatoprotective constituents of IR and that modulation of the AKT1-mediated Caspase-3/GSDME pathway may contribute to their protective actions against APAP-induced ALI. These findings validate its active compounds as promising therapeutic leads for ALI.

Baicalein, a naturally occurring flavonoid with well-documented anti-inflammatory and neuroprotective effects, has shown therapeutic promise in multiple models of neurological disorders. However, whether baicalein can counteract diquat-induced neurotoxicity remains uncertain. This study reveals that baicalein alleviates diquat-induced neuroinflammation and microglial pyroptosis in mice in a gut microbiota (GM)-dependent manner. In the in vivo experiments, multi-omics analyses demonstrated that baicalein elevates the GM-derived metabolite indole-3-propionic acid (IPA), which was sufficient to suppress pyroptosis. In parallel, IPA was identified as a critical mediator of baicalein's neuroprotective effects, as exogenous IPA administration recapitulated baicalein's protection, and baicalein treatment significantly elevated IPA levels. Mechanistically, through inhibiting the DEAD-box helicase 3 X-linked / GTPase-activating protein (SH3 domain) binding protein 1 pathway by in vitro experiments. Our study demonstrated that baicalein mitigates diquat-induced neuroinflammation, underscoring the therapeutic potential of targeting the GM to counteract herbicide-related neurotoxicity. Graphical

NASICON structured Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) has attracted widespread attention due to its simple preparation and excellent stability towards water and air. However, there are many problems such as high interfacial resistance between electrolyte and electrodes as well as low ionic conductivity of LATP. In this paper, the effect of F doping on Li ion diffusion channel in electrolyte was investigated in detail by density functional theory (DFT) calculation. The results show that F doping can effectively reduce the formation energy of Li vacancy. Meanwhile, it can also reduce the diffusion energy barrier and induce the high-energy Li ions at 36f site to carry out synergistic diffusion via various ways at the same time. Then, the F-doped LATP electrolyte was prepared successfully. Its ionic conductivity is as high as 0.358 mS cm −1 at room temperature . At the same time, the solid-state lithium metal batteries with F-doped LATP electrolyte shows a high capacity of 136.2 mA h g −1 at 0.5C and excellent cyclability for 200 cycles. These results demonstrate that F doping may be an effective way to improve the performance of LATP electrolyte.

A novel barium zinc borate contains π-conjugated [B3O6]3– anions and [B6O12]6– anion with edge-sharing BO4 tetrahedra, Ba6Zn6(B3O6)6(B6O12), has been successfully synthesized via a high-temperature solution reaction. In its structure, the isolated planar π-conjugated B3O6 groups are interconnected by ZnO4 tetrahedra via corner sharing to construct a [Zn3(B3O6)3]3– single layer parallel to the ab plane with the large Zn3B6 9-member rings. Two adjacent [Zn3(B3O6)3]3– single layers are interconnected by [B6O12]6– anions into a two-dimensional [Zn6(B3O6)6(B6O12)]12– double layer with 1D tunnels of Zn4B8 12-member rings along the a-axis. Neighboring such double layers are packed in an A–B–A–B... fashion along the c axis, and the Ba2+ ions act as counterbalance cations filling in the voids of double layers. All of the planar π-conjugated [B3O6]3– groups in Ba6Zn6(B3O6)6(B6O12) are in approximately parallel arrangement, producing large optical anisotropy and birefringence. The UV–vis–NIR absorption spectrum manifests that the UV cutoff edge for the title compound is below 200 nm. Ba6Zn6(B3O6)6(B6O12) possesses the largest birefringence (0.115@1064 nm) among the zincoborates reported. Its thermal stability, infrared spectrum, and theoretical calculations were also performed.

A noncentrosymmetric adduct, SbI3·(S8)3, is obtained by a facile solution method. It crystallizes in the trigonal space group R3m, and its structure features van der Waals force connected, isolated trigonal-pyramidal SbI3 and chairlike S8 units. SbI3·(S8)3 exhibits strong second-harmonic-generation responses around 4 times that of KH2PO4 (1.064 μm) and 1 times that of AgGaS2 (AGS; 2.1 μm) at 210–250 μm, respectively. Under both laser-radiation wavelengths, it exhibits type I phase-matching behavior. Its laser-induced damage threshold is measured to be around 26 times that of AGS under 1.064 μm. To better understand these optical data, theoretical calculations are performed to address its electronic structure and optical properties.

Black spot rot caused by Alternaria alternata is one of the major postharvest disease of apple fruit during logistic. This study evaluated in vitro inhibitory effect of 2-hydroxy-3-phenylpropanoic acid (PLA) at various concentrations on A. alternata and the possible mechanisms involved in its action. Results showed that different concentrations of PLA inhibited conidia germination and mycelial growth of A. alternata in vitro, and 1.0 g L −1 was the lowest effective concentration to suppress A. alternata growth. Moreover, PLA significantly reduced relative conductivity and increased malondialdehyde and soluble protein contents. PLA also increased H 2 O 2 and dehydroascorbic acid contents, but reduced ascorbic acid content. Additionally, PLA treatment inhibited catalase , ascorbate peroxidase , monodehydroascorbate acid reductase, dehydroascorbic acid reductase and glutathione reductase activities, whereas promoted superoxide dismutase activity. All these findings suggest that the possible mechanisms involved in the inhibitory effect of PLA on A. alternata included damaging the cell membrane integrity to cause electrolyte leakage and destroying reactive oxygen species balance.

Despite rapid development of perovskite nanocrystal (PeNC) light-emitting diodes (LEDs), it remains challenging to achieve efficient and stable blue PeLEDs , especially for pure-blue PeLEDs required for displays. Mixed halide CsPb(Br/Cl) 3 NC is a common strategy to achieve pure-blue emission, but suffers from low photoluminescence quantum yield (PLQY) and spectra instability. Here, a facile approach for the synthesis of high-quality pure-blue emitting CsPb(Br/Cl) 3 NCs is reported by introducing an organic sulfonate, phenyl trifluoromethanesulfonate (PTFMS), which works as an efficient surface passivator. As a result, the optimized PeNCs achieve a high PLQY of 85% and enhanced conductivity. Furthermore, the LED based on the optimized PeNCs is developed with pure-blue emission at 469 nm, which yields an external quantum efficiency (EQE) of 1.20% and luminance of 355 cd m −2 . More impressively, the device shows excellent spectra and operation stability under voltage bias , resulting from the suppressed ion migration channels by efficient defect passivation .

This work reports the design and preparation of novel organic (polyvinyl alcohol, PVA)-inorganic (neodymium nitrate, Nd(NO 3 ) 3 ) hybrid coatings on micro-arc oxidation (MAO) coating for magnesium (Mg) alloy corrosion protection . X-ray diffractometer , X-ray photoelectron spectroscopy, fourier transform infrared spectroscopy , field emission scanning electron microscope , Energy Dispersive X-ray spectrometer and surface roughness were applied to characterize the chemical composition and surface morphology of the coatings. The corrosion resistance of the coatings was evaluated by electrochemical and salt spray tests. The results suggested that the formation of PVA-Nd 3+ and PVA-Mg 2+ complexes promoted the enrichment of Nd 3+ on the surface, and thereby improved the sealing quality and compactness of the coating. Interestingly, when the coating was damaged, the Nd 3+ ions were transformed to their carbonates and covered the active sites, and thus exhibiting self-healing function. Further, the corrosion resistance of PVA-Nd 3+ modified MAO composite coating on AZ31 Mg alloy was improved.
