The challenges in high value-added utilization of lignin own to its wide molecular weight distribution and complex physicochemical properties associated with it. How to narrow the molecular weight of lignin and elucidate the differences in physiochemical properties related to molecular weight of lignins is of crucial importance for lignin conversion processing. In this study, lab-made Kraft and ethanol lignins were fractionated into several narrower molecular weight distribution components through a designed solvent system. The yield, molecular weight distribution, structural characterization and their physicochemical properties of each fractionated lignin were analyzed comparatively. The results indicated that the yield of ethanol lignin is higher (8.44 %) than that of Kraft lignin (5.26 %). Kraft lignin shows lower molecular weight (Mw=2480 g/mol), higher hydroxyl content (4.29 mmol/g), and lower content of β-O-4 and β-5 bonds compared to ethanol lignin (Mw=3682 g/mol, 2.10 mmol/g). Meanwhile, the phenolic hydroxyl content in both ethanol and Kraft lignins increased with the decrease of molecular weight. Furthermore, ethanol lignin demonstrated higher antioxidant activity and much higher (65times) tensile strength of lignin-based polyurethane elastomer than that of Kraft lignin-based polyurethane elastomer.

Hemp decortication, a crucial step in fibre processing, traditionally uses dry stems with low water content. However, processing hemp in a wet state has gained attention as an alternative method, especially with the development of harvesting techniques that decorticate the stems directly in the field. We investigated the effects of stems' initial moisture content on hemp fibre functional quality using freshly harvested hemp stems from different varieties. The stems were subjected to wet and dry decortication processes to evaluate potential differences in fibre damage and biochemical composition. Our experiments involved utilising a laboratory roller-breaking device for the initial decortication of the fresh hemp stems in their wet state and subsequent mechanical separation to assess fibre bundle integrity. As a comparison, we performed the same procedure on stems that were first dried before processing. We found that wet processing resulted in higher lignin levels in the fibre bundles, containing a higher quantity of middle lamellas, where lignin or another biochemical marker is typically found. The analysis revealed significant damage to the fibre bundles during the wet decortication process, as evidenced by the destruction and fibrillation of the bundles, clearly visible in scanning electron microscope (SEM) images. Interestingly, the dry conditions led to more fractures between fibres, while wet conditions allowed fractures between bundles and the surrounding histological structure. These findings suggest that wet processing may render the material more ductile, resulting in more complex crack modes, including combined torsion and delamination, leading to fracture paths passing through the cross-section of individual fibres. Consequently, the fibre bundles from wet processing may exhibit more structural damage than dry-processed fibre bundles. In conclusion, our study's findings are important as they highlight the severe damage that can occur to the fibre bundles during the decortication and separation of freshly harvested, moist hemp stems.

With the massive consumption of energy resources and increasingly severe environmental problems, the development of renewable, environmentally friendly, highly efficient energy conversion and storage devices has become a top priority. Here, a microstructure modulation strategy was proposed to fabricate the oriented regenerated cellulose (ORC) dielectric composites with outstanding mechanical and dielectric properties via a combination of dissolution, crosslinking, stretching, and hot-pressing techniques. ORC films with a stretch ratio of 100 % (ORC-100 film) exhibit a significant increase in displacement values (2.96 µC/cm2), breakdown strength (404.04 MV/m), dielectric constant (14.37 at 1 kHz), and energy density (3.42 J/cm3 at 250 MV/m) as compared to the unstretched regenerated cellulose films. These enhancements are attributed to the anisotropic alignment of cellulose chains and the enhanced crystalline phase of cellulose II, both of which are significantly higher in ORC-100 film. This work offers a feasible and serviceable approach for the development of environmentally friendly cellulose dielectric composites with high performance.

The primary factors limiting the yield of late-sown rapeseed are poor germination, restricted seedling growth and weak cold resistance of seedlings. Seed pelletization is known for its convenience of carrying functional agents to improve seed germination and growth, but little research has been reported on late-sown rapeseed pelletization. Therefore, the rapeseed Huayouza-137 was used to pelletize with biochar and functional agents including 6-benzylaminopurine (6-BA), abscisic acid (ABA), salicylic acid (SA) and trehalose (Tre). Then these seeds were subjected to low-temperature incubator tests and 2-years late-sowing field experiment to study the effects on germination, seedling growth, cold resistance and yield. The results showed that: (1) Compared to the control, the highest yield was observed in Tre1 (DSR=1:50), which increased by 9.75 % in 2021–2022 and 5.88 % in 2022–2023. The 6-BA3 (DSR=1:300), ABA3 (DSR=1:150), SA3 (DSR=1:150) increased yield by 2.75 % ∼ 9.01 % in two growing season. (2) The 6-BA3, ABA3, SA3, Tre1 showed significant improvement in emergence and germination and the relative growth rate of seedlings was significantly higher. (3) Compared with TX0, the pelletizing treatments (6-BA3, ABA3, SA3, Tre1) significantly increased osmoregulatory capacity and enzymatic antioxidant capacity, and reduced membrane lipid damage and reactive oxygen species damage in seedlings during overwintering. (4) The redundancy analysis and correlation network analysis revealed the late-sown rapeseed yield was significantly and positively correlated with the relative growth rate and the cold resistance of seedlings during the overwintering. Overall, this study provides a innovative approach to improve late-sown rapeseed yield by biochar-based seed pelletizing.

The high-value utilization of lignin-containing biomass waste generated during processing has gained widespread attention with the growing demand for renewable resources represented by bamboo. Herein, the 3,4-dichlorophenyl isocyanate (DCPI) was employed for mechanochemical derivatization/dispersion of bamboo powder after low concentration alkali pretreatment, in which an ultrafine hydrophobic carbamylated lignin-contained cellulose nanofiber (CLCN)1 with a diameter of 2±1 nm was obtained. By adjusting the usage of DCPI and milling time, the nanometric defibrillation of lignin-contained cellulose can be promoted effectively, which further endow high stability of CLCN-suspension. Whereas, the CLCN-films possessed controllable optical properties, wettability and UV resistance, ensuring the haze above 80 % with a total optical transmissivity up to 86 % at 550 nm. Furthermore, it maintained a UV blocking efficiency exceeding 90 %, accompanied by a water contact angle of 86.4° and tensile strength of 83.26 MPa. This is conducive to expanding the application of lignin-containing biomass waste.

The growing demand for renewable energy and environmental sustainability has led to the exploration of biodiesel as an alternative to fossil fuels. In the meantime, sustainable biomass conversion is utilized by the biorefinery to generate a wide range of value-added products. Among the feedstocks for biodiesel production, Madhuca indica or Mahua, a non-edible oilseed emerges as a viable source. Despite the advantages, the oil cake produced in this process causes environmental pollution, when discarded. In this study, the sulfonated M. indica biomass produced as waste in a one-pot reactive extraction process undergoes calcination and is utilized as a novel heterogeneous catalyst for biodiesel production through the transesterification process. The thermophysical properties of the biodiesel produced were characterized by FTIR (Fourier transform infrared spectroscopy), GC-MS (Gas chromatography/mass spectrometry), H¹ and C¹³ NMR (Nuclear Magnetic Resonance) analysis. Response Surface Methodology (RSM) was used to optimize this process, and the optimum conditions for a maximum yield of 90.01 wt% were a temperature of 70°C, a methanol to oil molar ratio of 15:1, with a catalyst of 3 wt%. Additionally, the performance and emissions characteristics of the MME15 (a blend consisting of 15 % M. indica methyl ester and 85 % diesel) and commercial diesel were studied in a direct injection CI engine in a full load condition the MME15's CO and HC emissions were 28.3 % and 18.2 % lower, respectively than those of commercial diesel. For NO emissions compared with diesel, MME15 emits 2.56 % more. The techno-economical studies highlight the efficiency and significance of the biorefinery of M. indica biodiesel by using a sulfonated catalyst and the payback period was determined as 3.7 years using the Aspen Plus Economic Analyzer.

Purple corn (Zea mays L.) contains numerous anthocyanins, and its excellent antioxidant ability that could promote health. However, the research is insufficient about the antioxidant ablilty and the lipid lowering effect in vitro of purple corn anthocyanins with hot-processing. Therefore, purple corn were treated with heat processing methods (boiling, steaming, and baking), and researched on the anthocyanins in purple corn. Oleic acid can inhibit fat deposition and free radicals induced by HepG2 cells. The results showed that anthocyanins of purple corn have significant antioxidant effects and lipid lowering in vitro. With unprocessed sample as the control, the antioxidant capacity and lipid lowering effect were higher with baked purple corn than that with steamed and boiled in vitro. This study provides new ideas and insights to create a new product channel for purple corn.

The hygroscopicity of bamboo leads to shrinking and swelling, which affects the processing and utilization of bamboo and its products. To enhance the understanding of the shrinking and swelling behavior, high-resolution microscopy and the digital image correlation technique were combined to investigate the differences in shrinking and swelling during the desorption and absorption processes at various internodes (No.3, 8 and 13). In addition, the effects of factors such as fiber distribution density and the presence of the pith ring on shrinking and swelling were analyzed. The shrinking and swelling in the radial direction varied with internode position, exhibiting a quasi-linear tangential deformation and a saddle-shaped radial deformation. As the internode position increased, the position of the maximum value of differential shrinking/swelling shifted closer to the interior of the bamboo. Upon removing the pith ring, a reduction in hygro-deformation in the inner part of bamboo was observed, while the outer part experienced an increase. The extent of this influence was directly related to the development of the pith ring. When the moisture content exceeded 10 %, hysteresis was noted in both tangential and radial deformations, as well as in the presence of pith ring. The gradient coefficient of deformation showed a pattern of initially increasing and then decreasing along the height of the culm, peaking at internode No. 8. This study explores the hygro-deformation phenomenon of bamboo and the impact of gradient levels, providing insights for understanding the bamboo-water relations, and optimizing the manufacturing of bamboo-based productions.

When the moisture content exceeded 10 %, hysteresis was noted in both tangential and radial deformations, as well as in the presence of pith ring. The gradient coefficient of deformation showed a pattern of initially increasing and then decreasing along the height of the culm, peaking at internode No. 8. This study explores the hygro-deformation phenomenon of bamboo and the impact of gradient levels, providing insights for understanding the bamboo-water relations, and optimizing the manufacturing of bamboo-based productions.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"222 ","pages":"Article 120052"},"PeriodicalIF":5.6,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654064","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}

Biochar has been proven to be an effective method for enhancing sweet potato yield. However, limited research has been conducted on the molecular and physiological mechanisms underlying biochar's regulation of starch biosynthesis. This study aimed to investigate the transcriptome sequencing, which revealed the effects of short-term biochar application (STBA) on tuberous roots of sweet potato and the. We designed four STBA treatments: 0 t·hm−2 (CK), 5 t·hm−2 (X5t), 10 t·hm−2(X10t), and 20 t·hm−2(X20t), through a comprehensive analysis encompassing physiological data and RNA-seq analysis. The investigation included a comprehensive analysis integrating physiological measurements with RNA-seq data to elucidate the underlying mechanisms. The results showed that STBA enhanced the availability of nitrogen and potassium significantly, while also elevating the soil's pH levels. The 20 t·hm−2 STBA substantially enhanced sweet potato yields by 72.21 %, and the starch content of all STBA was not significantly different with CK. STBA decreased the sucrose, starch, glucose, and fructose content of tuberous root by 3–12 %, 1–5 %, 5–8 %, and 5–16 %. DEGs analysis identified distinct gene regulation patterns following biochar treatments, with the 5–10 t·hm−2 dosages predominantly down-regulating genes, including those in starch and sucrose metabolism pathways. WGCNA analysis uncovered 11 modules, highlighting biochar's influence on hormone signal transduction pathways, which was validated through qRT-PCR of five key genes. The study's findings light on the impact of STBA on the starch quality of sweet potatoes and inform biochar application strategies in agriculture.

Balancing efficient fractionation with the structural intactness of lignin in lignocellulose pretreatment remains challenging. An innovative strategy with selective lignin solubilization/extraction/stabilization was developed to efficiently fractionate high-quality carbohydrates and well-preserve lignin from wheat straw employing a bio-based ternary deep eutectic solvent comprising dimethyl isosorbide/ethylene glycol/oxalic acid. Ultrahigh pretreatment efficiency (90.7 %), delignification rate (92.2 %), and cellulose recovery (88.4 %) were demonstrated in 37 min. Furthermore, excellent enzymatic digestibility (91.9 %), conversion of inhibitor-free carbohydrate hydrolysates to microbial lipid (8.3 g/100.0 g wheat straw), and lignin with good UV-blocking performance were obtained. The mechanistic insights into delignification were elucidated through Hansen solubility theory, revealing that the lower relative energy difference, strong hydrogen bonding cohesion, and ethylene glycol incorporation enabled efficient utilization of the sugar platform without compromising the structural intactness of lignin. This lignin solubilization-oriented strategy complements green and efficient pretreatment methods for lignocellulose that target holistic valorization and contribute to closed-loop biorefineries.
