Besides targeting low-voltage intercalation, NaTi2(PO4)3 (NTP) is a promising negative electrode material for non-aqueous sodium-ion batteries (SIBs). However, the low electronic conductivity of this material inhibits its potential applications. Herein, we report the controllable synthesis of four interesting porous NTP nanocubes via a one-pot solvothermal method. The as-synthesized products have shown excellent high-rate performance and cycling stability as SIB anodes. After 10 000 cycles at a 10C rate, 75.5% of the initial capacity is retained, which exceeds those of most of the reported SIB anode materials. Even at an extremely high rate of 100C, the NTP nanocubes can still deliver considerable reversible capacities after deep charging/discharging for 15 000 cycles. The superior electrochemical performances can be attributed to their unique nanostructures. We hope that such a finding of the new construction will enrich the NTP system and provide several possible candidates for SIB anodes.

Goat milk is nutritionally valuable and ranks as the second most consumed dairy in China, with Shaanxi Province being the national leader. However, systematic studies on regional quality variations, grading and spoilage mechanisms of it remain limited. In this study, 124 raw milk samples were collected from 14 major dairy goat breeding areas across Shaanxi. Our results revealed that significant spatiotemporal variations, and long-distance transportation affected milk quality by increasing microbial loads and reducing fat content ( P < 0.05). The grading model demonstrated high accuracy (91.8%) and reliability (AUC = 98.4%), with fat content being the most critical biomarker. Storage at 10 °C accelerated spoilage compared to 4 °C, with marked enrichment of Pseudomonas and Enterobacteriaceae . Multi-omics analysis identified seven genus-level microbial biomarkers and five key metabolites, which are linked to goat milk spoilage. This study provides a data-driven tool for raw goat milk quality assessment and grading, reveals core microbiological and metabolic mechanisms, and offers crucial insights for quality control in the dairy industry.

The 10-kDa chemokine interferon-gamma-inducible protein 10 (IP-10) is considered one of the most promising biomarkers for diagnosing both tuberculosis and COVID-19 infections. The blood samples of patients at different disease states contain different levels of IP-10, which need to be detected in a rapid, specific and ultrasensitive manner. Here, we report a bienzymatic chemiluminescence sandwich immunoassay (BCSI) assay for the ultrasensitive and stable detection of IP-10. In this assay, IP-10 is first efficiently captured using a double-antibody sandwich strategy. The detection antibody is linked to catalase (CAT) via a streptavidin–biotin signal amplification system to achieve highly efficient conversion of hydrogen peroxide (H 2 O 2 ) to oxygen and water. In the chemiluminescence (CL) reaction, horseradish peroxidase (HRP) acts as an efficient catalyst, and 4-bromophenol acts as an enhancer for the cyclic transition of HRP, which results in a strong and durable CL signal. The bienzymatic catalysis with CAT and HRP and the potentiation of 4-bromophenol enables the assay to be ultrasensitive and stable. The CL intensity was found to be well correlated with the detection of IP-10 at levels in the range of 0.71 to 125,000 pg/mL, which covers more than 6 orders of magnitude, with a detection limit of 0.63 pg/mL. The coefficient of variation was 1.49%, and the recovery range of IP-10 in serum was 86.21%-104.57%. This assay provides a wide linear range and high sensitivity and may be a promising method for the high-throughput detection of IP-10 in the diagnosis of tuberculosis and COVID-19.

Phosphorus with concentration above a few ppm in waters can easily cause eutrophication and poor water quality (e.g. algal blooming). In this study, we synthesized a non-porous gadolinium terephthalic acid (Gd-PTA) metal-organic framework (MOF) for efficient and rapid removal of phosphorus. Gd-PTA was prepared with gadolinium as the core metal center and terephthalic acid as the organic ligand, by which a well defined structure of new MOF was established. The adsorption isotherm and kinetics were well described by Langmuir isotherm equation and the intraparticle surface diffusion model, respectively. The maximum adsorption capacity was as high as 206.13- PO 4 3 − mg/g, which outperforms many reported and/or commercially available adsorbents (normmaly 5–150 PO 4 3 − mg/g). The adsorption was completed at the end of 10-min contact time, much faster than many reported adsorbents for uptake of anions (normmaly hours to days). The MOF performed very well in the uptake in phosphate containing solution with initial pH 3 to 9 and ionic strength (NaNO 3 ) of 0–1 M, and in the presences of competiting sulphate, nitrate, carbonate and humic acid (each with 30, 50, and 100 mg/L). The absorption of phosphate was mainly controlled by ion exchange between phosphate and organic ligand of MOF as well as the interaction between unsaturated metal center of coordination and phosphate. This study demonstrates that the newly developed MOF reported here is a promising adsorbent for cost-effective treatment of phosphorus in water and wastewater.

Royal jelly as a functional food has great potential to promote human health. As a unique ingredient in royal jelly, 10-hydroxy-2-decenoic acid (10-HDA) is a vital criterion to evaluate the quality of royal jelly. Current approaches for 10-HDA detection mainly rely on high-performance liquid chromatographic (HPLC), but it requires large-scale equipment and skilled technicians that are costly and time-consuming. Herein, we report a colorimetric sensing strategy for 10-HDA detection based on Ag(I) and tetramethylbenzidine (TMB), a widely used chromogenic reagent. Ag(I) can oxidize TMB to generate oxidized TMB (oxTMB) showing a light-blue color. Due to the chelation with Ag (I), the introduction of 10-HDA can prevent the generation of oxTMB that results in a color fading and a decrease in absorbance. This colorimetric sensing strategy enables highly sensitive detection of 10-HDA with a linear range from 1 μM to 10 μM and a limit of detection of 0.13 μM. More importantly, this 10-HDA assay allows for a visual readout either by a smartphone or the naked eye with low cost, convenience, and rapid response that has been successfully applied for evaluating the quality of royal jelly in actual samples. The sensing strategy developed in this work provides a new colorimetric approach that holds great promise as a point-of-care platform for the food industry.

Three types of metal-doped ETS-10 zeolites including Ni-ETS-10, Al-ETS-10, and Ga-ETS-10 were successfully synthesized by one-pot template-free hydrothermal treatments. The effect of doping metals on the crystallinity, morphology, textural property, and basicity of the produced zeolites was systematically studied. It was found that doping with an appropriate amount of Ni could enhance the crystallinity and basicity of ETS-10 zeolites in comparison with Al and Ga, and the Ni species mainly existed in two forms of framework coordination and exchange site connection within Ni-ETS-10. The catalytic evaluation by the liquid Knoevenagel condensation reaction of benzaldehyde with ethyl cyanoacetate confirmed the superiority of ETS-10 and metal-doped ETS-10 in comparison with the contrast base zeolites of NaY and KY. And the 0.4Ni-ETS-10 catalyst exihibted the best performance with 75.6 % yield of ethyl ɑ-cyanocinnamate (ECC) among all the synthesized (metal-doped) ETS-10 zeolites. It is reasonable to expect that the demonstrated work has important implications for the design and facile synthesis of new-type high-performance base zeolite catalysts.

Monodisperse silica nanospheres with different diameters between 100 and 700 nm were fabricated using a slightly modified Stöber process. Silica nanosphere monolayers in a hexagonal array based on hydrophobically modification were well deposited on top of a bare crystalline silicon solar cell by a Langmuir-Blodgett method. The antireflection effect of various diameter silica nanospheres coatings was simulated using Comsol Multiphysics simulations. Silica nanosphere hexagonal array coatings with four kinds of diameters were fabricated based on results of simulations. The efficiency of solar cells covered by silica nanospheres has improved significantly with a maximum of 11.41% at 119 nm diameter while that of the planar solar cells was 10.17%, which is attributed to the improved photocurrents arising from the broadband antireflection and optical absorption . The antireflection effects produced by Rayleigh (<1/10 wavelength) and Mie scattering (subwavelength) of different diameters silica nanosphere structures were discussed in detail.

Methyl caprylate is expected to be one of the main components of biodiesel due to its high cetane number and good oxidation stability. Details of the experimental speeds of sound in methyl caprylate are very scarce, especially in high-temperature regions. Therefore, the speed of sound in liquid methyl caprylate was measured by the Brillouin light scattering method in the temperature range of 298.22–608.38 K and at pressures of up to 10 MPa. The relative expanded uncertainty of the speed of sound is estimated to be less than 1.32% (coverage factor k = 2). The variation of the speed of sound with the temperature and pressure was analyzed. Besides, the correlation for the speed of sound as a function of temperature and pressure is presented based on the experimental data. The absolute average of relative deviation between the experimental data and the calculated results is 0.29%.

In this work, 9-mesityl-10-methylacridinium ion (Acr+-Mes) is found to act as an effective photocatalyst mimicking the function of oxidase. Upon visible light illumination, the excited Acr+-Mes is able to exhibit superior enzymatic catalytic activity for small molecular substrates as well as protein biomacromolecule (cytochrome c). The experiment results demonstrate that the Acr+-Mes oxidase mimic shows higher affinity to 3,3′,5,5′-tetramethylbenzidine (TMB) than natural horseradish peroxidase or the reported molecule oxidase mimic. The reaction mechanism is ascribed to the strong oxidation property of the long-lived electron-transfer state (Acr•-Mes•+) and the electron transfer from Acr•-Mes radical to dissolved oxygen to generate superoxide radicals, which can easily oxidize various substrates. On the basis of these observations, the light-activatable Acr+-Mes with an oxidase-like activity as the probe is utilized for cost-effective, sensitive, and highly selective colorimetric detection of two biothiols (L-cysteine and L-glutathione). The lowest detectable concentrations of L-Cys and L-GSH is 100 nM, which is lower than that of most of the reported methods for biothiols. Beyond this, we construct a series of visual molecular logic gates (AND, INH, and NOR) using the oxidase mimic-involved reaction systems.

High mechanical properties and flame retardancy of epoxy are important for its applications. A novel star-shaped flame-retardant 5,10-dihydro-phenohphosphazine-10-oxide functioned triazine (TRIDPPA) with high efficiency is synthesized, and its structure is characterized. TRIDPPA is used as the co-curing agent for diglycidyl ether of the bisphenol A/4,4-diaminodiphenyl methane system. The introduction of TRIDPPA greatly improves the flame retardancy of the cured epoxy resins. The epoxy resin (ER)/TRIDDPA1.0 resin acquires a limiting oxygen index value of 30.7% and UL-94 V-0 rating when the mass fraction of TRIDDPA is 1.0 wt% with only 0.086 wt% of phosphorus content. The cross-link density of ER/TRIDDPA1.0 is increased, and the glass transition temperature is improved by 5°C. Besides, tensile strength and toughness of ER/TRIDDPA1.0 are also enhanced.

Gold (Au) nanoparticles are promising photothermal agents with the potential of clinical translation. However, the safety concerns of Au photothermal agents including the potential toxic compositions such as silver and copper elements in their structures and the relative large size-caused retention and accumulation in the body post-treatment are still questionable. In this article, we successfully synthesized dendrimer-stabilized Au nanorods (DSAuNRs) with pure Au composition and a sub-10-nm size in length, which represented much higher photothermal effect compared with dendrimer-encapsulated Au nanoparticles due to their significantly enhanced absorption in the near-infrared region. Furthermore, glycidol-modified DSAuNRs exhibited the excellent biocompatibility and further showed the high photothermal efficiency of killing cancer cells in vitro and retarding tumor growth in vivo . The investigation depicted an optimal photothermal agent with the desirable size and safe composition.

A series of composite membranes (sPBIp3-CAUX) are prepared by using modified sulfonated polybenzimidazole with an optimal side link grafting degree of 30% as a polymer matrix and then doping with CAU-10-H. The hydrophobic alkyl side chains and hydrophilic sulfonic acid groups easily form microphase separated structures due to the polarity difference, which is conducive to the enhancement of proton conductivity. The introduction of CAU-10-H into the polymer effectively prevents the passage of vanadium ions because the vanadium ion transport path becomes more tortuous. The sPBIp3-CAU2 membrane has low vanadium permeability (3.1 × 10–9 cm2 min–1) and excellent ion selectivity (9.16 × 106 S min cm–3). In addition, the sPBIp3-CAU2 membrane shows good cell performance at 60 mA cm–2 with CE of 93.32% and EE of 83.03% compared with those of Nafion 117.
