This study focuses on windmill palm materials, investigating their fiber bundles and single fibers to examine microstructure, chemical composition, mechanical properties, and thermal characteristics. Findings reveal that windmill palm fiber possess a multicellular structure, with spindle-shaped single fiber parallelly aligned to create the overall fiber. By eliminating lignin and hemicellulose, highly crystalline (76.5 %) single fibers can be isolated. By loading resin microspheres at both ends of the fibers, the mechanical properties of single fibers can be successfully tested. The windmill palm single fibers exhibited a tensile strength in the range of 263±127 MPa, demonstrating a robust resistance to breaking under tension. Additionally, these fibers showcased a tensile elongation of 25.1±10.2 %, indicating a notable capacity for deformation before failure. The large strain fracture of windmill palm fibers mainly originates from the high tensile elongation of single fibers for the low molecular chain orientation, followed by the stretching of the amorphous regions such as lignin and hemicellulose at the connections between single fibers.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142553044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the gradual depletion of wild <em>Scutellaria baicalensis</em> (WS) resources, artificial cultivated <em>Scutellaria baicalensis</em> (CS) has gradually become the main source of Radix Scutellariae. However, it is believed that WS has better quality, and there are some problems in the artificial cultivation process, such as unreasonable planting mode leading to quality decline, which makes the production of high-quality Radix Scutellariae become an urgent need. It’s proved that rhizosphere microorganisms can affect the growth of medicinal plants, the accumulation of secondary metabolites and the ability to resist stress. However, how CS and WS affect the quality formation through the recruitment of rhizosphere microorganisms remains to be further explained. Therefore, UPLC was performed to explore the differences of flavonoids in different growth modes of <em>S. baicalensis</em>. Amplification sequencing technology was used to analyze the differences of rhizosphere microorganisms in different growth modes. Functional prediction, co-occurrence network analysis and correlation analysis between rhizosphere microorganisms and pharmacologically active ingredient were also used to explore the effects of rhizosphere microorganisms on quality formation of CS and WS. The results showed that though compared with CS, the contents of flavonoids in WS decreased, the relative abundance of stress-resistant rhizosphere microorganisms in WS increased significantly, the stress-resistant and adaptive-related pathways of WS rhizosphere microbial communities were significantly up-regulated. In addition, many microorganisms enriched in rhizosphere of CS were significant positive correlation with baicalin and wogonoside. Therefore, CS has higher flavonoid content, while WS has stronger resistance to stress.

To analyze these factors, Response Surface Methodology (RSM) paired with Central Composite Design (CCD) was employed. The quadratic model was identified as the best fit for the experimental data, evidenced by a high determination coefficient (R²) of 0.99, with all model parameters proving significant. A comprehensive characterization of the catalyst was conducted using various techniques. The surface and pore properties were examined using N₂ adsorption-desorption measurements. X-ray diffractometry (XRD) was employed for structural analysis, while X-ray photoelectron spectroscopy (XPS) presented the binding information of the sample. Fourier transform infrared spectroscopy (FT-IR) provided insights into the functional groups present. Thermal gravimetric analysis (TGA) assessed the thermal stability of the catalyst. Results revealed that ZIF-8 significantly improved biodiesel production, with optimal conditions identified at a reaction temperature of 160 °C, a duration of 2.5 h, and methanol to oil (M/O) molar ratio of 26, resulting in a biodiesel yield of 85 %. This yield is close to the predicted value, demonstrating the reliability of the developed model. The kinetic analysis was performed under optimal reaction conditions. From this, the activation energy (E_a) and the pre-exponential factor (A) were obtained to be 14.5 kJ/mol and 3.4×10⁻⁷ min⁻¹, respectively.

This solution not only meets the assumptions of the \"Green Chemistry\" concept but also creates the opportunity to improve the properties of plastics while reducing their production costs.

In the case of both straw and pomace, an increase in growth time and an increase in the free density of the foams were observed with an increase in the amount of added plant material. The analysis of morphology and chemical structure of the obtained composites led to the conclusion that the cellular structure, skin thickness, and functional groups present in biofillers had a direct impact on the functional properties of ISF.
