These devices, however, often rely on significant quantities of organic solvents or halogenated substances during manufacturing and encounter challenges related to cost and efficiency. In this work, a simplified layer-by-layer self-assembly technique was employed to design the coating, constructing a single-layer halogen-free intumescent flame retardant coating on the surface of wood pulp paper (WPP) through the interaction between phytic acid (PA, negative charge) and polyacrylamide (PAM, positive charge). Subsequently, a fluorine-free and environmentally friendly hydrophobic encapsulation layer was built over the flame retardant coating using a Polydimethylsiloxane-tetraethoxysilane (PDMS-TEOS) system. Notably, the modified samples exhibit multi-element synergistic flame retardant properties, with a limiting oxygen index (LOI) reaching 35.1 %, and reductions in peak heat release rate (pHRR) and total heat release (THR) by 66.4 % and 48.1 %, respectively, thereby ensuring fire safety during fuel recovery. Additionally, inspired by tree root penetration, a novel fuel recovery package was developed using waste cotton wool and modified paper, significantly enhancing the recycling efficiency of the modified paper. Overall, the hydrophobic, flame-retardant wood pulp paper constructed through this coating design demonstrates high flame safety and fuel recovery efficiency, offering promising prospects for marine environmental protection and sustainable development.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"222 ","pages":"Article 120078"},"PeriodicalIF":5.6,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654062","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}

However, conventional metal-supported catalysts often suffer from poor metal dispersion and particle agglomeration during lignin conversion, resulting in insufficient catalytic activity. To address these challenges, a novel biochar-encapsulated cobalt catalyst (Co@BC) was developed in this study for efficient lignin hydrogenolysis. The catalyst formed a unique thin carbon layer structure by encapsulating cobalt nanoparticles in biochar, which enhanced metal dispersion and prevented particle agglomeration. The performance of the catalysts was systematically evaluated at different calcination temperatures. Co@BC-650 showed the best results with a lignin liquefaction degree of 79.7 % and a monophenol yield of 19.1 wt%. This yield was significantly higher than that of the supported Co/BC-650 catalyst, which only reached 15.4 wt%. The thin carbon layer not only facilitated the reduction of cobalt species at 650 °C, but also provided antioxidant protection and maintained the stability of metallic cobalt, which was essential for H<sub>2</sub> adsorption and activation. In addition, Co@BC-650 exhibited excellent stability with little loss of activity after 3 cycles. This study provides an efficient and sustainable method for the selective production of monophenols from renewable lignin from industrial crops, which has the potential to be widely applied for biomass conversion and large-scale sustainable chemical production.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"222 ","pages":"Article 120076"},"PeriodicalIF":5.6,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653985","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}

This study presents a novel approach to fabricating metal-reinforced bamboo composite (MRBC) with exceptional performances, utilizing bamboo residues and nano-CuO without use of adhesives. The impact of raw material characteristics, including moisture content of bamboo powder and the amount of nano-CuO additive, on functional properties such as water resistance, flame retardancy and smoke suppression of MRBC was investigated. Also, the forming mechanism of MRBC was elucidated through examination of its microstructure, chemical composition, and thermal stability. Results indicated that the MRBC containing 20 wt% nano-CuO exhibited a high modulus of rupture (MOR) of 54 MPa, an impressive modulus of elasticity (MOE) of 9.3 GPa, a notable surface hardness of 44.4 kgf/mm, and low 24 h water absorption-thickness swelling of 6.5 %, all significantly surpassing those observed in conventional panels. The MRBC exhibited a tightly wrapped, adhered, and cross-linked process under high temperature and pressure conditions, facilitated by multiple synergistic effects such as lignin melting, hydrogen bond networking, physical structure entanglement, and material redox reaction, which contributed to a dense intertwined and consolidated structure. The MRBC demonstrated exceptional structural integrity throughout the combustion process, effectively mitigating potential damage caused by structural collapse due to the incorporation of nano-CuO, which also successfully suppressed smoke and toxic CO gas emissions during combustion. The MRBC showcased advantages of environmental friendliness, water resistance, high strength, flame retardancy and smoke suppression. These attributes position it as an optimal substitute for conventional panels and make it suitable for replacing metals in specific applications. Thus, it demonstrates significant market potential and promising prospects for sustainable development.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"223 ","pages":"Article 120053"},"PeriodicalIF":5.6,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, pH-shifting and/or ultrasonication remarkably strengthened sulfhydryl clusters and surface hydrophobicity, but decreased the disulfide bonds and lightness of CSMP.

The physiological regulation of ethylene-stimulated latex flow mainly involves processes such as alleviating laticifer plugging, prolonging latex flow duration, increasing laticifer turgor pressure, and enhancing latex stability.

This study aims to establish the link between these physiological changes and specific genes in the ethylene signaling pathway. We identified four ethylene dose-dependent response factors, namely HbRAP2.3, HbERF110, HbERF3, and HbERF1B, and a cluster of ethylene dose-dependent genes, including those encoding enzymes involved in latex stability, such as <em>HbPMCA4</em> and <em>HbGCL</em>, and those involved in latex coagulation, such as <em>HbGLU14</em> and <em>HbECH</em>. These genes exhibit a similar expression pattern with these ethylene dose-dependent response factors, and the promoter region of some contains the \"GCC-box\", the core sequence for ERFs binding. This suggests that they may be directly regulated by these ethylene dose-dependent response factors. Additionally, we cloned <em>HbRAP2.3</em>, which can activate the expression of latex flow-related genes <em>HbGLU14</em> and <em>HbECH</em>.
