Saleh, Muhammad Abdulkadir","doi":"10.1016/j.indcrop.2025.121956","DOIUrl":"https://doi.org/10.1016/j.indcrop.2025.121956","url":null,"abstract":"There has been significant interest in the use of green additives produced from bio-based materials within the lubricant industry. These additives are characterized by their non-toxic nature, cost-effectiveness, natural biodegradability, and diverse applications. The current study focuses on the synthesis of a Neem oil-derived homo-polymer, as well as a copolymer formed from Neem oil with Nanocrystalline cellulose (NCC). GC-MS analysis identified the fatty acid composition of neem oil, which was primarily dominated by the presence of oleic acid (∼19 %), which offers crucial reactive sites for the process of free-radical polymerization. This led to the formation of both homo-polymers and copolymers. Following this, FTIR confirmed the formation of both copolymer and homopolymer due to the absence of the olefinic peaks in the 1550–1680 cm⁻¹ region as opposed to their presence in the neat neem oil. The successful isolation of nanocrystalline cellulose (NCC) was validated through FTIR, which indicates a complete removal of the characteristic lignin peak around 1500–1600 cm⁻¹ and the hemicellulose carbonyl peak near 1735 cm⁻¹ , both of which are observable in the raw husk. The TGA analysis demonstrated the enhanced thermal stability of the copolymer, with about 5 % weight loss at 300°C in contrast to a 15 % loss for the homopolymer at the same temperature. The pour point and Viscosity Index of the base oil were analysed before and after the addition of the synthesized additives at different concentrations. Specifically, the polymers (both homo-polymer and copolymer) were evaluated at concentrations of 1 %, 2 %, and 3 % (w/v), whereas the NCC was assessed at 1 % and 2 % (w/v). The base oil containing 2 % copolymer was found to be optimal, yielding the highest Viscosity Index of 111.1 and a notably lower pour point of −14°C. These results confirmed the efficiency and applicability of synthesized NCC, a homo-polymer of neem oil, and copolymer as additives for lubricating oil to improve, specifically, its pour point and Viscosity Index.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"102 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145195046","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}

In this study, we present an efficient enzymatic cascade for the direct conversion of molasses into D-mannitol, a valuable sugar alcohol widely used in the food and pharmaceutical sectors. The cascade integrates three enzymes: invertase for sucrose hydrolysis, mannitol dehydrogenase (MDH) for D-fructose reduction, and glucose dehydrogenase (GDH) for in situ NADH regeneration via D-glucose oxidation, which simultaneously generates D-gluconolactone as a value-added coproduct. Two reaction formats were evaluated: a two-step system that sequentially optimizes enzyme-specific conditions, and a one-pot system enabling operational simplicity. The two-step method yielded 137 ± 13 mM D-mannitol, corresponding to ∼92 % conversion, while the one-pot system produced 123.1 ± 1.3 mM, corresponding to ∼95 % conversion under molasses conditions within 24 h. The molasses pretreatment was not essential for D-mannitol production. Enzymes maintained high catalytic activity in the complex molasses matrix, and glucose supplementation improved cofactor regeneration, eliminating residual D-fructose. This integrated strategy offers a sustainable and scalable platform for agro-industrial waste valorization by co-producing D-mannitol and D-gluconolactone, aligning with circular bioeconomy principles and advancing green bioprocessing technologies.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"28 3 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145195074","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}

Compared with the control, applications of MnO₂- and SiO₂-NPs markedly increased total flavonoid content (TFC) in <em>C. paliurus</em> leaves by 21.26–49.99 %, and enhanced per-plant flavonoid accumulation by 40.70–50.06 %. Conversely, applications of high-dose ZnO-NPs induced oxidative imbalance, resulting in a 30.25 % and 43.84 % decline in TFC and flavonoid accumulation respectively. Multi-omics profiling revealed that both MnO₂- NPs and SiO₂-NPs activated ROS-dependent pathways involving MAPK and glutathione signaling, while SiO₂-NPs may also promote flavonoid biosynthesis via enhancing carbon fixation and primary metabolism. The MYB-bHLH-WD40 complex (including <em>MYB113</em>, <em>bHLH42</em>, and <em>TTG1</em>) was identified as a central regulatory node, ranking among the top 10 contributors in O2PLS analysis and exhibiting strong correlations (cor &gt; 0.95) with flavonoid metabolites.

However, their accuracy is often limited because they struggle to capture the complex, nonlinear interactions among thermal factors. This study uses thermogravimetric analysis and derivative thermogravimetric analysis to examine the pyrolysis properties and thermal degradation behavior of flower stalk fibers from <em>Agave americana</em> waste under different heating rates (<em>β</em> = 5, 10, 15, 20, 25, and 30 °C/min). The results show a clear shift of both devolatilization zones to higher temperatures as <em>β</em> increases, with the first peak moving from 320°C at 5 °C/min to 350°C at 30 °C/min, and the second peak shifting from 410°C to 445°C over the same range. This shift is attributed to a decrease in heat transfer efficiency at higher <em>β</em>, which affects the thermal degradation kinetics. Artificial neural network (ANN) models, especially the architecture (5 × 17 × 1), were developed to model the pyrolysis process. The ANN model achieved a mean bias error of less than 2 %, a mean absolute error of less than 0.03, and a correlation coefficient of over 0.98, demonstrating strong agreement with experimental data. Comparisons with kinetic parameters obtained from Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose, and Starink methods indicated that the ANN slightly overestimated activation energies, with average predicted values of 135 kJ/mol compared to 125–130 kJ/mol from kinetic methods. The ANN also effectively predicted thermodynamic parameters, with enthalpy change values between 120–140 kJ/mol, Gibbs free energy around 110 kJ/mol, and entropy change values that varied slightly with minor deviations from experimental results.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"4 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145189387","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}

The surface of the superhydrophobic film had a micro/nano-scale structure similar to that of lotus leaves. The water contact angle (WCA) of superhydrophobic films reached 153°, and sliding contact angle (SA) was 5°. Owing to this unique structure, different liquid food droplets could roll off freely in a near spherical form on the chitosan phytate film surfaces, effectively reducing residue during container pouring.

Experimental results indicated that for temperatures below 160 °C, the drilling fluid properties exhibited a limited improvement following the inclusion of β-CDNSs. When the temperature was above 160 °C, hydrothermal carbonization occurred for an oil/water ratio below 9:1. The generated carbon spheres were adsorbed at the oil/water interface and served as emulsion stabilizers. These particles tended to form network structures and provided the desired rheological properties. They could also plug the micropores and reduce the permeability of the filter cake, thereby significantly reducing the filtration loss. The properties of conventional additives deteriorate gradually with an increase in the temperature; hydrothermal carbonization also changes the structure of β-CDNSs and generates carbon spheres above the critical temperature of 160 °C, which improves the performance of the invert emulsion drilling fluid.

Birch fibres are a major source of paper and fibre-based products. Tree age impacts the fibre structure, affecting the pulp quality produced from them. Understanding this effect is key to ensuring the sustainable use of wood. This paper presents the results of the most extensive study in Poland concerning the variability of selected parameters and structural indices of silver birch fibre structure depending on tree age. The study covered 23 locations in 3 age groups of 30, 50, and 70 years, where 414 trees were felled. A total of 12,420 fibres were measured. Tree age has a statistically significant effect on selected parameters and structural indices of silver birch fibres, except for the solids index. Mean fibre length, width, wall thickness, and slenderness ratio increased with tree age. Lumen width, Runkel ratio, rigidity index, Mühlsteph’s index, and flexibility coefficient values of 50-year-old trees differed from those of other age classes. Tree age has a relatively great and statistically significant effect on fibre diameter, wall thickness, and slenderness index. The study of the characteristics of birch wood aged 30, 50, and 70 years shows its high potential value in the pulp and paper industry. Due to the higher value and size of older wood, and for economic reasons, the paper industry uses wood from younger trees or older trees that do not qualify for industrial standards.","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"39 1","pages":""},"PeriodicalIF":5.9,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145189092","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}
