The global commitment to pivoting to sustainable energy and products calls for technology development to utilize solar energy for hydrogen (H 2 ) and value-added chemicals production by biomass photoreforming. Herein, a novel dual-functional marigold-like Zn x Cd 1 -x S homojunction has been the production of lactic acid with high-yield and H 2 with high-efficiency by selective glucose photoreforming. The optimized Zn 0.3 Cd 0.7 S exhibits outstanding H 2 generation (13.64 mmol h −1 g −1 ), glucose conversion (96.40%), and lactic acid yield (76.80%), over 272.80 and 19.21 times higher than that of bare ZnS (0.05 mmol h −1 g −1 ) and CdS (0.71 mmol h −1 g −1 ) in H 2 generation, respectively. The marigold-like morphology provides abundant active sites and sufficient substrates accessibility for the photocatalyst, while the specific role of the homojunction formed by hexagonal wurtzite (WZ) and cubic zinc blende (ZB) in photoreforming biomass has been demonstrated by density functional theory (DFT) calculations. Glucose is converted to lactic acid on the WZ surface of Zn 0.3 Cd 0.7 S via the photoactive species O 2 − , while the H 2 is evolved from protons (H + ) in H 2 O on the ZB surface of Zn 0.3 Cd 0.7 S. This work paves a promising road for the production of sustainable energy and products by integrating photocatalysis and biorefine.

Understanding the dynamic changes in antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is essential for evaluating the effectiveness of the vaccine and the stage for the recovery of the COVID-19 disease. A rapid and accurate method for the detection of SARS-CoV-2-specific antibodies is still urgently needed. Here, we developed a novel fluorescent lateral flow immunoassay (LFA) platform for the detection of SARS-CoV-2-specific IgM and IgG by the aggregation-induced emission carbon dots conjugated with the SARS-CoV-2 spike protein (SSP). The aggregation-induced emission carbon dots (AIE-CDs) are one of the best prospect fluorescent probe materials for exhibiting high emission efficiency in both aggregate and solid states. The AIE-CDs were synthesized and displayed dual fluorescence emission, which provides a new perspective for the design of a high sensitivity testing system. In this work, the novel LFA platform adopted the AIE carbon dots, which are used to detect SARS-CoV-2-specific IgM and IgG conveniently. Furthermore, this sensor had a low LOD of 100 pg/ml. Therefore, this newly developed strategy has potential applications in the areas of public health for the advancement of clinical research.

The quality of marinated meat could be assessed by the uniformity of marinade distribution within it. In this study, the diffusion behavior of sucrose inside the marinated beef was quantitatively characterized from 2D plane and 3D space using hyperspectral imaging (HSI) and finite element analysis (FEA), respectively. Visualization of sucrose content based on HSI showed that the distribution state of sucrose on marinated beef was not uniform. Subsequently, the diffusion behavior of sucrose in the 3D beef geometric model was simulated using FEA. Results revealed that the diffusion rate of sucrose on muscle tissues is significantly higher than other tissues, and the difference in diffusion behavior is the main reason for the inhomogeneous distribution of sucrose. The quantitative characterization of marinade diffusion behavior makes it possible to predict the marinade's transient distribution state, thereby determining the optimal marinade conditions for the meat. Therefore, the method proposed has practical significance for evaluating and regulating the quality of marinated meat products.

Identifying the components of Camellia oleifera honey and pollen and conducting corresponding toxicological tests are essential to revealing the mechanism of Camellia oleifera toxicity to honey bees. In this research, we investigated the saccharides and alkaloids in honey, nectar, and pollen from Camellia oleifera, which were compared with honey, nectar, and pollen from Brassica napus, a widely planted flowering plant. The result showed that melibiose, manninotriose, raffinose, stachyose, and lower amounts of santonin and caffeine were found in Camellia oleifera nectar, pollen, and honey but not in B. napus nectar, pollen, and honey. Toxicological experiments indicated that manninotriose, raffinose, and stachyose in Camellia oleifera honey are toxic to bees, while alkaloids in Camellia oleifera pollen are not toxic to honey bees. The toxicity mechanism of oligosaccharides revealed by temporal metabolic profiling is that oligosaccharides cannot be further digested by honey bees and thus get accumulated in honey bees, disturbing the synthesis and metabolism of trehalose, ultimately causing honey bee mortality.

Thermal barrier coatings with excellent thermal performance and corrosion resistance are essential for improving the performance of aero-engines. In this paper, (Y 3-x Yb x )(Al 5-x Sc x )O 12 (x = 0, 0.1, 0.2, 0.3) thermal barrier coating materials were synthesized by a combination of sol-gel method and ball milling refinement method. The thermal properties of the (Y 3-x Yb x )(Al 5-x Sc x )O 12 ceramics were significantly improved by increasing Yb and Sc doping content. Among designed ceramics, (Y 2.8 Yb 0.2 )(Al 4.8 Sc 0.2 )O 12 (YS-YAG) showed the lowest thermal conductivity (1.58 Wm −1 K −1 , at 800 °C) and the highest thermal expansion coefficient (10.7 × 10 −6 K −1 , at 1000 °C). In addition, calcium-magnesium- aluminum -silicate (CMAS) corrosion resistance of YS-YAG was further investigated. It was observed that YS-YAG ceramic effectively prevented CMAS corrosion due to its chemical inertness to CMAS as well as its unique and complex structure. Due to the excellent thermal properties and CMAS corrosion resistance, YS-YAG is considered to be prospective material for thermal barrier coatings.

Carbon nanomaterials have huge application prospects in the fields of materials science and biomedicine. Graphene oxide (GO) can be served as an excellent carrier with good loading capacity and biocompatibility. However, lamelayers of GO are prone to aggregation and difficult to stably disperse in solution. Only relying on the mesh graphene sheets as a carrier still cannot achieve a good loading efficiency. Therefore, oriented layered graphene oxide pad (OGO) is synthesized and used as a carrier for ligand fishing. The structure of OGO exhibits good reproducibility and recyclability, and its regular open channels and low pore curvature can effectively ensure a high density of fishing sites and flow speed, improving the loading capacity and storage stability. According to the amount of immobilized cell membranes protein (CMP), OGO can reach 1.5 to 2 times loading capacity of GO. The established CMP@OGO is stable within 48 h at 4 ° C, and the reuse rate of OGO is 93.04 ± 0.67%. Finally, salvianolic acid B, deoxyshikonin, and shikonin were identified as potentially active compounds in comfrey combined with a high-performance liquid chromatography-hybrid linear ion trap/orbitrap mass spectrometer. It can provide a promising platform for OGO to screen active compounds in high throughput.

Dopamine (DA) in bovine serum served as a vital physiological biomarker for evaluating livestock health status and conducting translational biomedical research. Accurate and rapid detection of DA was therefore essential for agricultural breeding monitoring and clinical biological analysis. In this work, a novel Hemin@P 2 Mo 18 nanocomposite with peroxidase-mimicking activity was successfully prepared via a facile, green solvent-free grinding strategy. The introduction of water-soluble H 6 P 2 Mo 18 effectively suppressed the aggregation of free hemin molecules and yielded solid-phase Hemin@P 2 Mo 18 . Relative to natural peroxidases, the synthesized Hemin@P 2 Mo 18 featured convenient recovery and excellent reusability. Given the excellent peroxidase-mimicking activity of Hemin@P 2 Mo 18 , a sensitive and selective colorimetric platform was constructed for DA detection. Moreover, the proposed approach showed high selectivity against common interfering substances and excellent stability under different conditions. It was successfully applied to the quantitative determination of DA in bovine serum samples with satisfactory recovery rates ranging from 96.8% to 100.2%. This study provided a green and efficient solvent-free grinding synthesis strategy for high-performance POM-based nanozymes. It also offered a feasible and practical approach for rapid biomarker detection in complex biological matrices, which showed great application potential in veterinary monitoring and biosensing analysis.

Ultra-high temperature ceramic matrix composites (UHTCMCs) are essential for thermal protection in extreme aerospace environments. The role of ultra-high temperature ceramic (UHTC) matrix architecture in governing thermal transport and ablation resistance remains insufficiently understood. In this work, high-thermal-conductivity C f /HfC-SiC composites with distinct matrix structures were fabricated via slurry infiltration (SI) and precursor infiltration and pyrolysis (PIP). The PIP route, enabled by molecular-scale precursor infiltration, yields a uniform HfC dispersion within the SiC matrix, establishing a continuous phonon transport network that delivers an axial thermal conductivity as high as 296 W/(m·K). In contrast, the SI route leads to localized HfC enrichment in inter-bundle pores, which, upon ablation, oxidizes into abundant HfO 2 particles that pin the SiO 2 melt, producing a dense and erosion-resistant oxide scale. Consequently, the SI-HfC composite exhibits a linear ablation rate of 0.042 μm/s and a mass ablation rate of 3.61 mg/s, with only a 9.31% degradation in axial thermal conductivity after 100 s ablation at 4.5 MW/m 2 , suffers less thermal conductivity degradation than the PIP-HfC (11.80%). This work elucidates the processing-microstructure-property correlations in UHTCMCs, providing a quantitative basis for route selection in high-thermal-conductivity thermal protection systems.

In the post-COVID-19 pandemic, the stockpiling of medicines by most households could pose a pollution risk as they may expire over time. In this study, an expired amoxicillin act as carbon source to prepare peroxide-like functional carbon dots nanozymes doped Fe (Fe-CDs). Importantly, a high-value treatment technique for expired drugs was proposed. To obtain outstanding catalytic performance, compared with other commonly doped metals, Fe-CDs catalyzed the oxidation of TMB by H 2 O 2 with the highest efficiency. In particular, the oxidation product of TMB (oxTMB) would be alleviated in the presence of antioxidants. Significantly, antioxidants could briefly cause the fading of oxTMB and the fading level was correlated with various concentrations of antioxidants. Importantly, a sequential injection strategy was introduced to control the fading process caused by antioxidants to improve the accuracy. Under the optimum condition, the limit of detection (LOD) was 0.13 mg/L (for ascorbic acid) with the linear concentration range from 0.5 to 15 mg·L −1 . Finally, the total antioxidant capacity (TAC) in human serum samples were evaluated successfully.

A magnetic stirrer‑assisted media milling (MS‑MM) method was developed for drug‑drug nano‑cocrystals. • MS‑MM showed a 60% lower theoretical energy consumption than conventional ball mill‑based milling based on rated power. • The nano‑cocrystals enabled synchronous and nearly 100% release of both drugs within 5 min. • Freeze‑drying with sucrose preserved cocrystal structure and stability for up to 90 days. Gefitinib (GTB) and dasatinib (DAS) are two tyrosine kinase inhibitors with synergistic potential, but their poor and disparate solubility hinders fast and synchronous release in combination therapy. While drug-drug nano-cocrystals offer a solution for synchronous and fast release of two drugs in combination, their development is limited by bottlenecks in low-energy and scalable preparation. Herein, a facile magnetic stirrer-assisted media milling (MS-MM) method was developed to fabricate GTB-DAS drug-drug nano-cocrystals for the first time. The formulation and preparation process of nano-cocrystal suspensions were optimized, validated, and successfully scaled up by 25-fold. Compared with conventional ball mill-based media milling, MS-MM showed a 60% lower theoretical energy consumption when compared on the basis of rated power. Comprehensive characterization (SEM, TEM, PXRD, DSC, FTIR) of the lyophilized powder confirmed the successful fabrication of GTB-DAS nano-cocrystals with cocrystal structure preserved. In vitro dissolution studies demonstrated that the nano-cocrystals integrated synchronous release and a high dissolution rate, achieving nearly 100% release of both drugs within 5 min. This work provides a facile, energy-efficient, and scalable platform for the development of compound formulations involving poorly water-soluble drugs. Facile and energy-efficient magnetic stirrer-assisted media milling (MS-MM) enables the preparation of GTB-DAS drug-drug nano-cocrystals with 60% lower energy consumption, uniform particle size (∼229 nm), preserved cocrystal structure, and synchronous, fast release (∼100% within 5 min).

Feeding is regulated not solely by intrinsic energy demands, but also by various environmental cues. Food sight and odor are two essential food-related cues that promote human eating; nonetheless, the underlying neural mechanisms remain unknown. Here, we show that during energy deficit, food sight inhibits the ventromedial hypothalamus (VMH) neuronal activity, thereby promoting feeding and food-associated contextual memory in mice. VMH neurons receive direct GABAergic input from the suprachiasmatic nucleus (SCN) that is rapidly activated by food sight. Either knockout of VMH RuvB-like 2 (RUVBL2) or inhibition of RUVBL2-expressing neurons in the VMH (VMH RUVBL2 ) promotes feeding and food-associated contextual memory. Interestingly, VMH RUVBL2 neurons exert these effects by sequentially projecting to the supramammillary nucleus (SuM) and the hippocampal dentate gyrus (DG). Together, this study identifies SCN GABA → VMH RUVBL2 → SuM→DG neural circuit underlying food sight-promoted feeding and food-associated contextual memory in mice.

Ascorbic acid (AA) plays an important role in many life processes. The chronic nutritional deficiency of AA will lead to the symptoms of scurvy. Therefore, the sensitive quantitative detection of AA is most important in the pharmaceutical analysis, food industry and diagnostic application. In this study, a dual-functional magnetic metal–organic frameworks (Fe 3 O 4 @SiO 2 @UiO-PBA) nanoparticles was synthesized by modifying phenylboronic acid to the surface of magnetic UiO-66-NH 2 via postsynthetic modification for selectively and sensitively florescent detection of AA. Due to the abundant amino groups and grafted phenylboronic acid, the proposed nanoparticles have the dual properties of hydrophilicity and boronate affinity. Under optimum conditions, the obtained Fe 3 O 4 @SiO 2 @UiO-PBA nanoparticles can detect AA within 30 s, and has a good linear relationship with the concentration of AA in the range of 5.0–60 μM with a detection limit of 2.5 μM (S/N = 3). In addition, the prepared Fe 3 O 4 @SiO 2 @UiO-PBA nanoparticles showed excellent selectivity and great potential application in the highly efficient determination of trace AA in vitamin C tablets. These results indicated that a convenient method was proposed to develop fluorescent probes for rapid and sensitive detection of trace AA in real samples.
