To address the growing demand for fire safety in diverse scenarios, it is imperative to develop flame retardant wood with integrated properties such as moisture resistance, self-cleaning functionality, and enhanced weather durability. Wood was vacuum impregnated with biomass phytic acid (PA) and proteolytic product L-arginine (LA) to prepare a green flame retardant wood (PALA-Wood), and then SiO₂ nanoparticles were anchored to the flame retardant wood using 1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTES) modified Polydimethylsiloxane (PDMS) to obtain a super hydrophobic, flame retardant, and smoke suppression wood (PALA@FPS-Wood). In comparison with natural wood (NW), the PALA@FPS-Wood demonstrated self-extinguishing characteristics in the vertical combustion test, achieved the UL-94 flammability grade V-0, and exhibited a reduction in total heat release and total smoke production by 48.80 % and 81.82 % respectively. Furthermore, the limiting oxygen index exhibited rising from 20.3 % to 58.1 %. The modified wood as evidenced by a water contact angle (WCA) of up to 155.6°. The super hydrophobic coating effectively isolates the flame retardant from the external environment, The modified wood exhibited excellent leaching resistance even after 14d of immersion in water. More importantly, it can withstand different adverse environmental conditions. Consequently, the findings of this research provide an effective method for the preparation of high weather resistance flame retardant wood materials with potential applications in both indoor and outdoor settings.

Current cultivation and research on Watercore apples lack precise evaluation methods and non-destructive detection techniques for Watercore content. In response, this study exploits the intrinsic distribution characteristics of Watercore and utilizes a RIFE interpolation-based feature slice stacking method to reconstruct a 3D model of individual Watercore—a task unattainable using conventional approaches. Employing the complete 3D Watercore model as a reference, the study further integrates near-infrared spectroscopy with the GAF-ConvNeXt algorithm to achieve five-class non-destructive detection of Watercore. Experimental results demonstrate that the MIoU between the RIFE-interpolated features and the original Watercore features attains a value of 0.826, thereby indicating high reliability. The reconstructed 3D models typically exhibit a central void, multiple uniformly distributed independent pillar-like structures along the periphery, and a greater volume in the upper half relative to the lower half. Furthermore, the five-class detection accuracy achieved using the GAF-ConvNeXt algorithm attains 98.10 %, thereby offering a more precise and scientifically robust method for the non-destructive evaluation of Watercore content in apples.

The global sugar industry is developing alternative revenue streams through product diversification, as a strategy to deal with the volatility of global sugar prices. Techno-economic analysis was conducted on chemical products derived from furfural, by utilizing and expanding the available processing capacity at an existing furfural plant annexed to a sugarcane mill. The products 2-methylfuran (2-MF), 2-methyltetrahydrofuran (MeTHF), tetrahydrofurfuryl alcohol (THFAL), maleic anhydride (MA) and tetrahydrofuran (THF) were considered as potential derivatives from the 20 000 tons per year of furfural produced by the existing plant, for which Aspen Plus® process simulations were developed. The economic analysis revealed that furfuryl alcohol production was consistently the most profitable option, achieving the highest financial net gain of US$2 million per year, with marginal changes within the viable production scales. THFAL production also showed potential profitability, yielding an average net gain of 5 million US$ per year and 3/8 probability of success, which could be improved to an 8/8 probability with a 35 % increase in the selling price. In contrast, conversion of furfural the other products consistently exhibited net financial loss. Among these, 2-MF had the smallest financial net loss, becoming profitable with a 90 % increase in the current market price for a bio-based product. THF required a 110 % increase in biobased and 120 % in fossil-based prices, while 2-MeTHF needed increments of 140 % and 160 %, respectively. Furfural conversion into MA production became profitable with fossil-based market price increases of 230–300 %. The production of bio-based MA, MeTHF and THF may be more profitable when considering intermediates other than furfural for their production, such as 5-Hydroxymethylfurfural (5-HMF), 1,4-butanediol, bio-butanol, or levulinic acid.

In agriculture, Carbon Dots (CDs) have been shown to enhance plant photosynthesis, boost antioxidant capacity and increase stress resistance. Additionally, CDs can serve as pesticide carrier, to improve the stability, solubility and targeted delivery of pesticide molecules. In this study, novel weed-based CDs derived from Commelina communis were developed. Using peas, Chinese cabbage, and aphids as the test objects, the CDs can promote the growth of seedling, within a certain concentration range, where they can significantly increase the fresh weight of plants. This growth-promoting effect is mainly due to the facilitation of iron ion absorption and the synthesis of chlorophyll by the CDs, thereby enhancing plant photosynthesis. In addition, CDs-flonicamid nanocomposite can improve the adhesion of pesticides on the leaf surfaces, and enhance the control effect against aphids. This work lays a foundation for the development of innovative pesticide formulation based on the CDs and their broader application in agriculture.

The overuse of plastic products has resulted in severe environmental pollution, driving the need for sustainable alternatives. Bamboo presents a highly promising solution due to its eco-friendly, fast-growing, renewable, and biodegradable properties. However, current bamboo species are not yet meet the large-scale production demands, primarily due to challenges like prolonged vegetative growth, unpredictable flowering time and low genetic transformation efficiency, which hinder targeted genetic improvement. The emergence of Artificial Intelligence (AI) and Internet of Things (IoT) offers a potential breakthrough in developing specialized bamboo varieties for this purpose. This review explores the potential applications of AI in bamboo breeding, including predicting flowering time to accelerate breeding processes, managing large datasets for accurate forecasting, efficiently designing strategies for genetic transformation and gene editing, optimizing species selection for various applications, providing decision-making tools for bamboo introduction sites, and facilitating the rapid propagation of improved varieties. Additionally, it discusses the future challenges and solutions for integrating AI into bamboo breeding, such as establishing regional bamboo germplasm banks and databases, constructing comprehensive genetic datasets from diverse sources, identifying key genetic and environmental factors influencing bamboo traits, developing efficient breeding design methods, and enhancing intelligent cultivation, harvesting, and product processing. Future research should be focused on overcoming these challenges to accelerate the development of bamboo varieties that meet the sustainability goals of the "Bamboo as a Substitute for Plastic" initiative.

Aging was traditionally used to enhance the quality, active ingredients, and physiological activities of some traditional Chinese medicine such as Artemisia argyi leaves, but it is a time-consuming process. This study estimates the potential of using solid-state fermentation by Lactiplantibacillus plantarum as a faster alternative to aging. A. argyi leaves were subjected to solid-state fermentation, and the contents of flavonoids, polyphenols, and polysaccharides were measured. Antioxidant, anti-tyrosinase, and anti-xanthine oxidase activities were also assessed, alongside changes in essential oil composition. Results indicated that solid-state fermentation significantly increased flavonoid and polyphenol contents in fermented leaves, with levels comparable to or higher than those in aged ones. Antioxidant activities and enzyme inhibition abilities were significantly enhanced in fermented leaves compared to both aged and unfermented ones. The composition of essential oils in fermented leaves exhibited notable changes. These findings suggest that short-term solid-state fermentation with L. plantarum can effectively improve the active ingredients and physiological activities of A. argyi leaves, potentially offering a viable alternative to the traditional aging process. This approach could be applied to A. argyi leaves and other herbs requiring aging, improving efficiency in herbal medicine processing.

Precise tumor imaging and effective drug delivery remain significant challenges in cancer therapy. To address these challenges, a novel drug delivery system, Us-Fe NPs/PLA-PEG@PTX, was developed for combined MR imaging and anti-tumor therapy. Ultra-small Fe₃O₄ nanoparticles (Us-Fe NPs) were stabilized with citrate and modified with polylactic acid-polyethylene glycol (PLA-PEG) polymers to enhance biocompatibility and facilitate paclitaxel (PTX) incorporation. PTX was initially extracted from the bark of the Pacific yew tree. The system achieved an encapsulation efficiency of 72.3 % and a loading content of 6.74 %. PTX was released in a controlled manner at both neutral (pH 7.4) and mildly acidic (pH 5.5) conditions. MR imaging studies indicated potential for T1-weighted imaging. Us-Fe NPs/PLA-PEG@PTX demonstrated dose-dependent cytotoxicity (IC₅₀ = 0.06 μg/mL) against MDA-MB-231 cells. PEG modification reduced cellular uptake. Flow cytometry showed G2/M phase arrest and apoptosis induction, and confocal microscopy revealed microtubule disruption. These results suggest that Us-Fe NPs/PLA-PEG@PTX is a promising nano-platform for MR imaging-guided anti-tumor therapy.

High iron (Fe) supply can enhance Cd accumulation in the aerial tissues of poplars, but the underlying mechanisms remain unknown. Here, we exposed Populus cathayana to either 0 or 120 µM CdCl₂ in combination with either 50 or 200 μM FeCl₃ for 30 days. We found that high Fe supply alleviated Cd-induced decreases in the concentrations of Fe and photosynthetic pigments in the leaves of P. cathayana, thereby improving the photosynthesis and total biomass. Additionally, high Fe increased the Cd^2 + influxes on the root tips and promoted Cd translocation from the roots to the aboveground tissues of P. cathayana. Consequently, the concentrations and total amount of Cd were increased in the aerial tissues of P. cathayana after adding high Fe. Interestingly, in the roots of Cd-treated P. cathayana, the expression levels of genes involved in cell wall remodeling were altered upon supplementation with high Fe, whereas the expression of transporter genes remained unchanged. High Fe addition resulted in the reconstruction of root cell walls of Cd-exposed P. cathayana, which reduced the Cd deposition in root cell walls, thereby promoting Cd translocation from the roots to the aerial tissues. A regulatory network dominated by several transcription factors and miRNAs, such as MYB103, WRKY33, miR397, and miR858, probably modulated the high Fe-caused root cell walls remodeling. These results suggest that high Fe enhances Cd accumulation in the aboveground tissues of P. cathayana by reconstructing the root cell walls, which is probably modulated by a regulatory network at both transcriptional and post-transcriptional levels.

Steam reforming of bio-oil is a promising technology for the industrial-scale conversion of biomass into hydrogen energy, in which the catalyst plays the crucial role. This study proposes a Ni-Ca-Al-Ce-O catalyst, prepared by CaO loading onto Ni/CeO₂·Al₂O₃, and tested in the two-stage adsorption-enhanced reforming of biomass pyrolysis oil for hydrogen production. The effects of carrier type and Ni loading on the physicochemical properties of the Ca modified Ni-based reforming catalyst and its reforming performance were investigated, and its reusability was tested finally. The results revealed that more Ni metal active sites are available on CeO₂·Al₂O₃ compared to biochar as carrier. However, side reactions such as ketonization were significantly promoted due to the metal oxides in red mud (RM), resulting in a large amount of methane as a by-product over the Ni/RM catalyst. When Ca additive introduced on the well selected Ni/CeO₂·Al₂O₃, the selectivity of hydrogen in the reforming gas was enhanced. Meanwhile, more spinel NiAl₂O₄ was formed due to the interaction between NiO and Al₂O₃, which enhanced the stability and activity of the Ni-Ca-Al-Ce-O catalyst. With a Ca/Al ratio of 1:1, Ni was more uniformly dispersed, and the yield and selectivity of hydrogen reached 73.35 % and 76.90 %. In the reusability tests, the yield of hydrogen remained above 60 % after six runs, which was superior to that of similar reforming catalysts, suggesting that the proposed Ni-Ca-Al-Ce-O catalyst is reliable in terms of reusability.
