Medium chain triglycerides (MCTs) are regarded as an important ingredient for functional foods and nutraceuticals.Cinnamomum camphoraseed kernel oil (CCSKO) contains more than 95% medium chain fatty acids (MCFAs), which is a significantly higher level than palm kernel oil (62%) and coconut oil (55%). However, the safety assessment of CCSKO, as the only natural MCT oil rich in capric acid and lauric acid found so far in the world, has not been fully verified. The study aimed to investigate the 90-day sub-chronic oral toxicity and teratogenicity of CCSKO. In the sub-chronic oral toxicity study, no clinically significant adverse events occurred in male or female Sprague–Dawley (SD) rats with CCSKO daily administration for 13 weeks. Moreover, there were no dose–response relationships between CCSKO and body-weight gain, food intake and food utilization in male or female SD rats. No significant differences (p> 0.05) were found in the hematological properties or organ weights between the male and female SD rats. In the teratogenicity test, no toxicological signs were observed in either Wister pregnant rats or fetuses. The no-observed-adverse-effect level of CCSKO was determined to be more than 4 mL/kg body weight. These results suggested that CCSKO may be an excellent edible oil with high oral safety.

The main challenge to the use of vegetable oils as green lubricants is their oxidative stability. In this work, biolubricants with efficient antioxidant properties have been specifically designed and synthesized with the aim of maximizing the oxidative stability of vegetable oils by combining biophenols (p-coumaric, ferulic, and sinapic acids) with epoxidized ring-opened soybean oil in a single molecule. The synthetic products were named OIS-ESO-PCA (epoxidized ring-opened soybean oil grafted with p-coumaric acid), OIS-ESO-FA (epoxidized ring-opened soybean oil grafted with ferulic acid), and OIS-ESO-SA (epoxidized ring-opened soybean oil grafted with sinapic acid), respectively. Biophenols improve biolubricant antioxidant properties, addressing energy, and environmental challenges. The modified samples were characterized by Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance (NMR). The free radical scavenging activity of the oil samples was evaluated using the DPPH (1,1-diphenyl-2-trinitrophenylhydrazine) method and was found to be much higher than that of the soybean oil (SBO). The oxidation resistance and thermo-oxidative stability of the oil samples were evaluated based on pressure differential scanning calorimetry (PDSC), rotary bomb oxidation test (RBOT), and thermogravimetry (TGA). Compared with SBO, the oxidative induction time of OIS-ESO-PCA, OIS-ESO-FA, and OIS-ESO-SA increased by 118%, 296%, and 384%. The modified oils showed excellent antioxidant properties compared to the SBO. Therefore, biophenolic acid can be effectively used to improve the antioxidant properties of vegetable oils. Graphical Antioxidant capacity of bio-phenolic oil samples.

Pu’er raw tea, a representative tea with a positive correlation between quality and storage time, has a unique aging process. It can not only reduce the heavy astringent taste of newly produced tea, but also has a complex and fragrant aging aroma. However, the extremely slow natural aging process often takes years or even decades for quality transformation, along with the risk of termite infestation, odor absorption, etc. This study found that UV-C irradiation could significantly accelerate the aging process of tea. It enhanced the richness of the aroma, while reducing astringency and creating a smoother and mellower taste. The results of substances analysis revealed an increase in key aroma compounds such as alcohols, aldehydes and terpenes, and a decrease in catechin and caffeine with UV-C irradiation, which is consistent with the natural aging trend. An efficient and safe rapid aging technology of Pu’er raw tea has been successfully established.

Traditional scintillators rely on rigid inorganic matrices with high- Z elements, whose mechanical inflexibility restricts applications in multiple scenarios. Developing an efficient scintillator that combines inorganic properties with flexibility is a desirable yet highly challenging goal. We pioneered an inorganic metafabric scintillator paradigm through self-sustained slip system engineering, transforming brittle all-inorganic scintillation materials into ductile textile architectures, yielding intrinsically conformally flexible scintillators that adhere seamlessly to complex, curved surfaces. The ultimate all-inorganic scintillator delivers near-unity quantum yield, with scintillation output more than 10 times higher than that of previous polymer matrix–based flexible scintillators. Using these metafabric scintillators, a multimodal x-ray interactive wearable platform (X-Wear) was developed, and their applications in body-centered flexible detection and imaging, mobile health, visual radiation monitoring, and breathable radiation shielding were successfully demonstrated. This work offers a previously undefined paradigm for a scintillator system design strategy that maintains the high performance of inorganic scintillators while adding the functionality of being conformally flexible and wearable of fabrics.

Dynamic manipulation of terahertz waves is crucial for advancing rapidly evolving terahertz technologies. Recently, intercalation in 2D materials has emerged as a powerful strategy for tuning their physical and chemical properties, enhancing their potential for terahertz modulation applications. However, the terahertz-band response during intercalation and the underlying optical response mechanisms remain poorly understood. Herein, the tunable terahertz properties of the reduced graphene oxide films are investigated via ionic liquid intercalation and elucidate the associated terahertz response mechanism. The free charge carriers transport characteristics during the intercalation process are extracted using Drude–Smith model. The mechanism behind the terahertz response primarily stems from the intercalation of ionic liquid into the reduced graphene oxide films, resulting in an increase in the number of free carriers responding to terahertz waves. These results provide valuable insights for graphene-based tunable terahertz wave control and open a route toward exploring the intercalation mechanism in 2D materials.

Developing Pt-based core–shell catalysts with ultralow Pt loading, superior performance, and extended durability holds tremendous potential for advancing electrochemical energy storage and conversion technologies. However, current synthetic limitations persist in achieving atomically efficient Pt monolayer deposition on nonprecious metal substrates, hindering the maximization of Pt atomic utilization for cost-effective catalyst design. Here, we demonstrate a galvanic replacement strategy to synthesize tensile-strained platinum single-atom-layer (Pt SAL) on α-MoC substrates. The Pt SAL catalysts enable cooperative catalysis between adjacent Pt sites while maintaining nearly 100% atomic utilization efficiency. For alkaline hydrogen evolution, the Pt SAL/α-MoC catalyst exhibits optimized reaction energetics, reducing activation barriers for water dissociation, hydrogen adsorption, and H2 desorption compared to typical Pt/C. As a result, the Pt SAL catalysts exhibit superior hydrogen evolution reaction (HER) performance, with a mass activity of 1.71 A mgPt–1 at an overpotential of 50 mV, surpassing commercial Pt/C by 6.35-fold and single-atom catalysts by 7.68-fold. Remarkably, the Pt SAL catalysts reveal negligible activity decay after 10,000 cycles, with density functional theory (DFT) calculations attributing this stability to strong Pt–Mo interfacial bonding. In situ Raman spectroscopic studies reveal dynamic interfacial water restructuring that accelerates reaction kinetics. This work establishes a versatile synthesis approach for noble metal SAL catalysts and explores their role in designing high-performance electrocatalysts for heterogeneous catalysis.

MXenes have emerged as a highly promising material for next-generation patterned flexible sensing devices owing to their exceptional electrical conductivity, biosafety, and processability. In this study, we present a facile polyelectrolyte-assisted aerosol jet printing (AJP) strategy for fabricating MXene-based flexible sensors with largely improved printing quality for the applications in humidity and temperature sensing. By leveraging the electrostatic interactions network between sodium alginate (SA)-modified MXene ink and a chitosan (CS) substrate, the sensor achieves densely and stably packed MXene nanosheets with minimized defects. The intercalated SA molecules not only improve printing quality of AJP, but also enhance the humidity and temperature sensitivity of the MXene/SA patterns by modulating the interlayer spacing and functional groups within MXene layers. The resulting MXene/SA@CS sensor achieves a temperature coefficient of resistance (TCR) of 1.08% °C −1 (30–110 °C) and exhibits real-time responses to humidity changes from human motions with the largest 356 ± 9% resistance response rate and the shortest rapid response/recovery times (0.30 s/2.00 s). Its excellent antimicrobial properties and biocompatibility highlight the potential for wearable health monitoring and human-machine interfaces. Finally, the AJP-printed MXene sensors with programmable structures were successfully applied as a noncontact controller via finger movement detection.

The size dependence of metal nanoparticles is a critical factor affecting catalytic activity, as their geometric and electronic properties vary significantly with size. This study proposes a strategy combining rapid Joule-heating with solid-phase synthesis to prepare Cr/Sn-Beta bimetallic catalysts of various sizes via ultrafast thermal shock (UTS, heating rate: 1850 °C/s) and conventional muffle furnace annealing (MFA, heating rate: 5 °C/min). HRTEM results reveal that the bimetallic particle size of Cr/Sn-Beta catalysts prepared via UTS technique is only 2.55 nm, compared to 6.54 nm for catalysts obtained through conventional MFA method. Combined with XRD, BET, H 2 -TPR, UV–vis and FT-IR characterization, it is further confirmed that the ultra-high heating/cooling rate and second-short heating duration of the UTS method achieved efficient embedding of Cr and Sn within the zeolite micropores, which conferred precise tailoring of the particle size. The correlation between particle size and catalytic activity was investigated using the LA production from cellulose as a model reaction. In this work, the superior size effect of bimetallics nanoparticles prepared by UTS synthesis strategies was emphasized, providing insights into the geometry-activity relationship that will guide the rational design of catalysts in terms of morphology and particle size.

The introduction of noble metal nanoparticles effectively improves the photocatalytic performance of TiO2 due to the retarded recombination time of the photo-generated electron-hole pairs as well as raised charge transfer rate at interfaces within the composites. In this study, spherical TiO2 particles were prepared by sol-gel reaction and converted into anatase phase by calcination treatment. Ag nanoparticles were deposited on the spherical TiO2, yielding an optoplasmonic core-satellite composite structure. The coverage of Ag nanoparticles on the TiO2 surface was tuned by altering the duration of electroless plating. Due to the enhanced interaction between metal nanoparticle and dielectric component, the photodegradation of organic dyes was promoted accordingly. It was found that with proper Ag deposition degree, the optoplasmonic particle demonstrates the improved photocatalytic performance under ultraviolet and visible excitation. This composite particle was further evaluated in the experiments of practical copper electroplating solution, in which the optoplasmonic particles exhibit promoted photocatalytic activity. This developed structure is therefore a powerful candidate for the low-cost removal of organic additives.

Solvatochromic luminescent materials that can change their luminescence color upon solvent treatment have attracted considerable attention owing to their frontier applications in sensing and information encryption technologies. However, existing solvatochromic luminescent materials typically suffer from a slow response rate, limited color tunability, insufficient luminescence efficiency, and complicated synthesis process. Herein, a facile solvent-assisted and solubility-driven powder-to-powder strategy is developed for quick and mass synthesis of solvatochromic luminescent organic–inorganic manganese(II)-based halide microcrystals. The as-synthesized 0D green-emissive (TMA) 2 MnCl 4 (TMA: tetramethylammonium) and 1D red-emissive (TMA)MnCl 3 microcrystals can be reversibly converted into each other upon contact with different solvents. The solvent-induced phase transformations are accompanied by the strip of TMACl or MnCl 2 components, leading to the change of the coordination number of Mn 2+ and therefore the crystal field strength. Correspondingly, the emission color realizes a reversible switching between green and red. Notably, the phase transformation exhibits high selectivity toward solvents, and a fast response time in just 0.9 s from (TMA) 2 MnCl 4 to (TMA)MnCl 3 . The advances in these solvatochromic luminescent materials provide exciting opportunities for constructing a series of multicolor anti-counterfeiting and information encryption patterns. This work provides new insights for solvatochromic material design and promotes advanced encryption development.

The migration and accumulation mechanisms of trace elements (As, Pb, Cr, Cu, Ni, Zn, Mn) from coal fly ash in soil-plant systems critically constrain its sustainable utilization. Through integrated approaches including sequential chemical extraction, leaching experiments, electron probe microanalysis, and meta-analysis of bioconcentration data, this study reveals ash-type-dependent element levels with migration capacity: Mn > As > Zn > Cu > Ni > Cr > Pb, governed by their chemical speciation and mineral associations. Elements were classified into three activity groups based on activity and effective mass percentages, aligned with RAC risk levels. Divergent risk evaluations emerged: Nemerow index and ecological risk index indicated moderate pollution (Pz = 2.76) and slight risk (RI = 64.25) based on total content, highlighting differing RAC evaluation outcomes considering speciation. Meta-analysis of a robust bias-tested dataset demonstrated ash generally elevates trace elements in rice but not corn/wheat, with root accumulation exceeding shoots and application rates > 10–20 % significantly increasing concentrations. Crucially, by comparison between predicted values from pollution indices that based speciation concentrations and empirically measured elemental bioconcentration data, residual fractions (F3/F4/F5) positively correlated with plant bioaccumulation, whereas bioavailable fractions (F1/F2) dominated ecological hazards. These findings provide: (1) a speciation-based framework for environmental risk assessment prioritizing F1/F2, and (2) phytoremediation strategies targeting F3/F4/F5, enabling balanced coal ash reuse and risk mitigation through differentiated management of chemical fractions.

Developing highly efficient catalysts to reduce and convert CO 2 holds profound significance in addressing the global energy and environmental crises. In this work, an innovative hybrid photocatalyst is elaborately designed that integrates a metal–organic framework (MOF) and CdS quantum dots (QDs). The coordination and architecture structure of MOF crystals is readily modulated by increasing the number of benzenes in ligands, achieving a high coordination rate of Rh complex close to 100%. This structural optimization creates a hierarchical network featuring abundant exposed active sites and large pore size for fast mass diffusion. More importantly, the integrated CdS QDs refine the electronic state of Rh, further enhancing efficient electron transfer. Coupling with formate dehydrogenase (FDH), this hybrid photocatalyst not only demonstrates exceptional performance in converting CO 2 into formate but also simultaneously promotes the highly efficient regeneration of key coenzyme nicotinamide adenine dinucleotide phosphate (NADPH), with an outstanding yield of 85.6%. This work provides a straightforward and feasible method for regulating the coordination architecture and electron transfer of hybrid photocatalysts, offering valuable insights for developing highly active and robust catalysts.
