This research investigated the effect of strengthening in bamboo-reinforced concrete (CB) columns with pilecap systems by incorporated rebar to improve seismic performance as well as prevent cracking and early failure. The parameters observed were lateral load capacity, drift ratio, relative energy dissipation and collapse patterns. The test specimens consisted of 6 bamboo-reinforced concrete columns with a reinforcement area ratio (ρ_b) of 6 %. Among these specimens, three columns were strengthened with 6 mm steel (B6) and another with 8 mm steel (B8). The control specimens were bamboo-reinforced concrete columns without strengthening (CB) and steel-reinforced concrete columns (CS), with a reinforcement area ratio of 6 % and 1.4 %, respectively. Each column was tested and subjected to cyclic lateral loads according to ACI 375.1–19 and ASTM 2126–19 with a constant axial load of 54.85 kN. B6 and B8 had greater lateral load capacity, stiffness, ductility and drift ratio than CB and CS. B6 and B8 achieved an energy dissipation ratio greater than CB and almost the same as column CS. These results suggest that the connection points of bamboo-reinforced concrete column-foundation or beam-column connections should be reinforced to improve seismic performance. The application of bamboo-reinforced concrete portal structures in simple rural houses will require strengthening at the connection points to ensure livable and technically safe houses.

本文研究了竹材混凝土（CB）柱在桩承系统中加入钢筋的加固效果，以提高其抗震性能，防止开裂和早期破坏。观察到的参数包括横向承载能力、漂移比、相对能量耗散和倒塌模式。试件为6根竹筋混凝土柱，配筋面积比（ρb）为6 %。其中3根柱采用6 mm钢（B6）加固，1根柱采用8 mm钢（B8）加固。对照试件为未加固竹筋混凝土柱（CB）和钢筋混凝土柱（CS），加固面积比分别为6 %和1.4 %。按照ACI 375.1-19和ASTM 2126-19的要求，对每根柱进行循环横向载荷测试，恒定轴向载荷为54.85 kN。B6和B8的横向承载能力、刚度、延性和漂移比均高于CB和CS。B6和B8的能量耗散比大于CB，与CS柱基本相同。这些结果表明，竹筋混凝土柱-基础连接点或梁柱连接点应进行加固，以提高抗震性能。竹筋混凝土门式结构在简单农村房屋中的应用需要在连接点进行加固，以确保房屋的宜居性和技术安全性。

Molecularly imprinted polymers were employed for the purification and enrichment of flavonol glycosides and other flavonoid compounds to address the challenges of low content and structural similarity of polyphenolic flavonoids in plants, which render their separation very difficult. A magnetic molecularly imprinted polymer (MMIP) was synthesized via surface imprinting technology on Fe₃O₄@SiO₂ using vitexin as the template. Computational simulations identified methyl methacrylate (MMA) as the optimal functional monomer, with a template-to-monomer binding ratio of 1:6 and methanol as the most suitable porogen. Characterizations by TEM, XRD, VSM and FT-IR confirmed the successful synthesis of the MMIP under optimized conditions, which exhibited high adsorption capacity, rapid mass transfer and good regenerability. Binding experiments demonstrated that the MMIP had a maximum adsorption capacity of 16.1 mg/g. When directly applied to bamboo Leaves, the MMIP enabled the isolation of high-purity flavonoids, with HPLC successfully detecting six flavonoid compounds.

针对植物中多酚类黄酮含量低、结构相似等问题，采用分子印迹聚合物对黄酮醇苷类及其他类黄酮化合物进行纯化富集。以vitexin为模板剂，在Fe₃O₄@SiO₂上采用表面印迹技术合成了磁性分子印迹聚合物（MMIP）。计算模拟结果表明，甲基丙烯酸甲酯（MMA）是最佳的功能单体，模板与单体的结合比为1:6，甲醇是最合适的多孔剂。通过TEM、XRD、VSM和FT-IR表征，证实了在优化条件下成功合成的mip具有吸附量大、传质速度快、可再生性好等特点。结合实验表明，mip的最大吸附量为16.1 mg/g。当直接应用于竹叶时，MMIP可以分离出高纯度的黄酮类化合物，高效液相色谱法成功检测到6种黄酮类化合物。

The rising prevalence of micronutrient deficiencies globally necessitates innovative approaches for food fortification, particularly through the utilization of natural sources. We investigated the potential of bamboo shoot powder as a nutritional fortifier in enhancing the mineral content of common food items, specifically biscuits, salted snacks (namkeen) and noodles. The significance of food-to-food fortification is highlighted, which leverages locally available, nutrient-rich ingredients to improve dietary quality while aligning with cultural practices. The findings reveal that the incorporation of freeze-dried bamboo shoot powder significantly (P ≤ 0.05) enhances the mineral profiles of the fortified products, with notable increase in potassium content from 163.7 mg/100 g in control biscuits to 412 mg/100 g in fortified biscuits, representing a 152 % increase. Similarly, the fortified salted snacks exhibited a potassium level increase from 256.7 mg/100 g to 577.3 mg/100 g, a 125 % enhancement. In noodles, the potassium content increased significantly (P ≤ 0.05) from 160.7 mg/100 g to 603.3 mg/100 g, indicating a remarkable 275.5 % increase. Additionally, the calcium content in fortified noodle increased from 29.3 mg/100 g to 42.7 mg/100 g, while iron levels in the fortified noodles increased from 2 mg/100 g to 3.3 mg/100 g, marking a significant (P ≤ 0.05) 63.5 % enhancement. Our study underscores the importance of employing innovative processing techniques, such as freeze-drying, to preserve the nutritional integrity of bamboo shoots, making them a viable option for fortification strategies aimed at combating malnutrition. Overall, this research contributes to the ongoing discourse on food fortification and public health nutrition, highlighting the potential of bamboo shoot powder to enhance dietary quality and address critical nutritional gaps in modern diets.

全球微量营养素缺乏症日益普遍，需要采用创新的食品强化方法，特别是通过利用自然来源。我们研究了竹笋粉作为营养强化剂在提高普通食品（特别是饼干、咸味小吃和面条）中矿物质含量方面的潜力。强调了食物对食物强化的重要性，它利用当地可获得的营养丰富的成分来提高饮食质量，同时符合文化习俗。结果表明，冻干竹笋粉的加入显著（P ≤ 0.05）提高了强化饼干的矿物质含量，其中钾含量从对照饼干的163.7 mg/100 g显著增加到强化饼干的412 mg/100 g，增加了152 %。同样，强化咸味零食的钾含量从256.7 mg/100 g增加到577.3 mg/100 g，增加了125 %。面条中钾含量从160.7 mg/100 g显著提高到603.3 mg/100 g，显著提高了275.5 % （P ≤ 0.05）。此外,强化面条中的钙含量从29.3增加 42.7毫克/ 100 g  毫克/ 100 g,而铁水平强化面条从100  毫克/克增加到3.3 毫克/ 100 g,标志明显(P ≤ 0.05)63.5 %增强。我们的研究强调了采用冷冻干燥等创新加工技术来保持竹笋营养完整性的重要性，使其成为旨在对抗营养不良的强化策略的可行选择。总的来说，这项研究为食品强化和公共卫生营养的持续讨论做出了贡献，突出了竹笋粉在提高膳食质量和解决现代饮食中关键的营养缺口方面的潜力。

We investigated whether industrial transfer, an essential tool for optimizing factor allocation, contributed to the enhancement of total factor productivity (TFP) in China’s bamboo industry. To explore this relationship, we constructed a theoretical framework and employed a two-way fixed effects model. Industrial transfer was analyzed from two dimensions: changes in relative output value and changes in relative resource allocation. We found that: (1) The TFP of China’s bamboo industry was primarily driven by technological progress, with scale efficiency and technical efficiency playing a lesser role. (2) Industrial transfer, measured by relative output value change and relative resource change, significantly improved the TFP of the bamboo industry. This conclusion remained robust after accounting for endogeneity and conducting robustness tests. (3) The influence mechanism analysis revealed that in the transfer-in regions, industrial transfer boosted the TFP of the bamboo industry by optimizing the local industrial structure. However, in the transfer-out regions, it reduced land-use efficiency, hindering the development of the TFP in the bamboo industry. (4) The heterogeneity analysis revealed significant regional disparities in the effects of bamboo industry transfer on TFP. Specifically, the positive impact was more pronounced in central and western regions.

本文研究了产业转移作为优化要素配置的重要工具，是否有助于提高中国竹业的全要素生产率。为了探究这一关系，我们构建了理论框架，并采用了双向固定效应模型。从相对产值变化和相对资源配置变化两个维度分析产业转移。研究发现：(1)中国竹业全要素生产率主要受技术进步驱动，规模效率和技术效率的作用较小；(2)以相对产值变化和相对资源变化衡量的产业转移显著提高了竹产业的全要素生产率。在考虑内生性并进行稳健性检验后，这一结论仍然是稳健的。(3)影响机制分析表明，在转移区域，产业转移通过优化当地产业结构，促进了竹业全要素生产率的提高。但在外转地区，土地利用效率降低，阻碍了竹业全要素生产率的发展。(4)异质性分析表明，竹业转移对全要素生产率的影响存在显著的区域差异。具体而言，中西部地区的积极影响更为明显。

In the present study the effects of various parameters, including age of the culm, different heights of the culm and positions across the culm wall on the fibre characteristics of Ochlandra wightii were examined. The variation in fibre length, fibre width, lumen diameter and fibre wall thickness were recorded. Biometric properties such as the Runkel ratio, slenderness ratio, flexibility ratio and shape factor were analysed. Younger bamboo culms (below 1 year to 1–3 years) are better suited for pulp and paper production because of their desirable fibre qualities. The fibres of mature bamboo (more than 3 years) were less pliable, thicker and stiffer, reducing their suitability for use in papermaking.

本研究考察了不同的参数，包括茎龄、不同的秆高和跨秆壁的位置等，对白绒草纤维特性的影响。记录纤维长度、纤维宽度、管腔直径和纤维壁厚的变化。分析了龙克尔比、长细比、柔韧性比和形状因子等生物特征。较年轻的竹竿（1年以下至1 - 3年）更适合纸浆和纸张生产，因为它们具有理想的纤维品质。成熟竹子（3年以上）的纤维柔韧性较差，更厚、更硬，降低了它们在造纸中的适用性。

The incidence and severity of climate-related problems such as flooding, erosion and extreme heat are increasing across the globe. Such problems are in part attributed to the construction industry’s dependency on high CO₂-emission materials such as concrete and steel. Although there is a range of alternative materials, such as bamboo, which are in abundant supply, have low carbon footprints and are great thermal insulators, their use is quite low in Nigeria. We investigated how bamboo, specifically Bambusa vulgaris, from Abuja, Nigeria, could help meet the demands of building construction while being resilient to climate change. Laboratory tests were done to establish the physical, mechanical and durability properties of bamboo to evaluate its performance under different environmental conditions. Average water absorption percentages for fresh and dry bamboo samples were determined to be 16.0 % and 19.1 %, respectively, with moisture content averaging at 28.0 % and 17.7 %, respectively. The dry specimens had the greatest tensile strength, with a value of 84.8 MPa. The average compressive strengths were 13.7 MPa and 16.6 MPa for fresh and dry bamboo samples, respectively. We provide quantitative information on the physical and mechanical properties of Bambusa vulgaris, demonstrating its structural performance and environmental impact as well as its sustainability and potential ability to counteract the negative effects of climate change. Our research will assist in the formulation of building regulations and standards in addition to encouraging the use of bamboo in eco–friendly construction uses.

在全球范围内，洪水、侵蚀和极端高温等与气候有关的问题的发生率和严重程度都在增加。这些问题部分归因于建筑业对混凝土和钢铁等高二氧化碳排放材料的依赖。虽然有一系列替代材料，如竹子，供应充足，碳足迹低，是很好的隔热材料，但它们在尼日利亚的使用率相当低。我们调查了来自尼日利亚阿布贾的竹子，特别是普通竹子，如何帮助满足建筑建设的需求，同时又能适应气候变化。通过室内试验，建立了竹材的物理、机械和耐久性能，评价了竹材在不同环境条件下的性能。鲜竹和干竹样品的平均吸水率分别为16.0 %和19.1 %，平均含水率分别为28.0 %和17.7 %。干态试样抗拉强度最大，为84.8 MPa。鲜竹和干竹的平均抗压强度分别为13.7 MPa和16.6 MPa。我们提供了竹的物理和机械特性的定量信息，展示了它的结构性能和环境影响，以及它的可持续性和潜在的能力，以抵消气候变化的负面影响。我们的研究将有助于制定建筑法规和标准，并鼓励在环保建筑中使用竹子。

The production of bamboo charcoal in minimum viable reactors, made from reused paint cans and placed inside wood-burning stoves, represents an innovative and frugal solution for carbon sequestration in the form of biochar. We explore the potential of this approach in Brazil, a country with a strong tradition of using wood-burning stoves for cooking, and then discuss the implications of domestic biochar production for mitigating global warming. We also examine the social, environmental and agricultural benefits of small-scale bamboo biochar production in wood-burning stoves, including the use of the biochar as a fertilizer for gardens and backyards through soil incorporation, aimed at enhancing fertility and storing carbon over long periods. Each batch produced an average of 80 g of bamboo biochar with a carbonization time of 30 min. Based on the projection of 14 million Brazilian households using wood stoves, if this simple yet efficient technology was adopted it could sequester more than 200,000 tonnes of carbon annually in the form of biochar.

在最小可行反应器中生产竹炭，由重复使用的油漆罐制成，并放置在燃木炉内，代表了以生物炭形式进行碳封存的创新和节俭的解决方案。我们探索了这种方法在巴西的潜力，这个国家有着使用燃木炉灶烹饪的强大传统，然后讨论了国内生物炭生产对缓解全球变暖的影响。我们还研究了在木材燃烧炉中生产小规模竹生物炭的社会、环境和农业效益，包括通过土壤结合将生物炭用作花园和后院的肥料，旨在提高肥力和长期储存碳。每批平均产竹炭80 g，炭化时间30 min。根据对1400万巴西家庭使用木柴炉的预测，如果采用这种简单而高效的技术，每年可以以生物炭的形式吸收20多万吨碳。

Switching to bamboo cutlery in food delivery could reduce plastic pollution and associated carbon emissions in the life cycles. Current bamboo cutlery studies focus on comparing either disposable or reusable types with plastics but lack systematic comparisons of both types against plastics. This study fills that gap by using a life cycle assessment (LCA) approach to analyze and compare the carbon emissions of disposable and reusable bamboo cutlery versus plastic cutlery in food delivery scenarios. Under a single-use scenario, both disposable and some reusable bamboo cutlery items exhibited lower global warming potential (GWP) than plastic cutlery. Notably, reusable bamboo knives and forks reached break-even points with their plastic counterparts after only two uses. Sensitivity analysis showed that the GWP of disposable bamboo cutlery was most sensitive to energy consumption during processing (30.2 %), while for reusable bamboo cutlery, the use phase had the greatest impact (42.9 %). The emission reduction pathway scenario demonstrated that optimization of electricity supply during processing had a relatively limited effect due to constraints in China’s renewable energy share. In the context of food delivery, both disposable and reusable bamboo cutlery show strong potential as substitutes for plastic. For reusable products, ensuring sufficient frequency of use and improving recovery rates are key to maximizing environmental benefits. This study provides scientific evidence and data support for policymakers to enhance the “Bamboo as a Substitute for Plastic” strategy and promote sustainable development in the food delivery industry.

在送餐中改用竹制餐具可以减少塑料污染和生命周期中相关的碳排放。目前的竹筷研究侧重于一次性或可重复使用的竹筷与塑料的比较，但缺乏对这两种竹筷与塑料的系统比较。本研究通过使用生命周期评估（LCA）方法来分析和比较一次性和可重复使用的竹餐具与塑料餐具在送餐场景中的碳排放，填补了这一空白。在一次性使用情况下，一次性和一些可重复使用的竹餐具的全球变暖潜值（GWP）都低于塑料餐具。值得注意的是，可重复使用的竹刀叉在使用两次后就达到了与塑料刀叉的盈亏平衡点。敏感性分析表明，一次性竹餐具的GWP对加工阶段的能耗影响最大（30.2% %），而可重复使用竹餐具的GWP对使用阶段的能耗影响最大（42.9% %）。减排路径情景表明，由于中国可再生能源份额的限制，加工过程中电力供应的优化效果相对有限。在送餐方面，一次性和可重复使用的竹餐具都显示出替代塑料餐具的巨大潜力。对于可重复使用的产品，确保足够的使用频率和提高回收率是最大化环境效益的关键。本研究为决策者加强“竹代塑”战略，促进外卖行业可持续发展提供了科学依据和数据支持。

To ensure bamboo-based composites can withstand harsh environments, it is important to develop superhydrophobic and mildew-resistant coatings for the surfaces of the product. Achieving these functions on bamboo surfaces remains a challenging research problem. We applied a phytic acid (PA)-based hybrid coating to bamboo surfaces using a layer-by-layer self-assembly technique, and superhydrophobicity was further enhanced through modification with low surface energy substances. Scanning electron microscopy-Energy disperse spectroscopy (SEM-EDS) mapping results initially confirmed the successful creation of a microscale structure with improved hierarchical roughness on the bamboo surface. Following modification with octadecylamine (OA), the polyethyleneimine (PEI)/PA-Fe^3 + /OA/Bamboo demonstrated outstanding superhydrophobic performance, with a water contact angle reaching 151° and remaining above 150° without significant change over 2 min. Despite undergoing abrasion, scratch and tape peel tests, the PEI/PA-Fe³⁺/OA/Bamboo maintained high hydrophobicity, with a water contact angle remaining above 140°. Finally, phytic acid-based hybrid metal coordination complexes created a dense protective coating on the bamboo surface. This coating both prevented Aspergillus niger from accessing internal nutrients and inhibited its adhesion to the bamboo surface. Thus, the successful application of the superhydrophobic coating enhanced the mildew resistance of bamboo.

为了确保竹基复合材料能够承受恶劣的环境，开发产品表面的超疏水和防霉涂层非常重要。在竹子表面实现这些功能仍然是一个具有挑战性的研究问题。采用逐层自组装技术将植酸（PA）基杂化涂层应用于竹材表面，并通过低表面能物质改性进一步增强其超疏水性。扫描电子显微镜-能量分散能谱（SEM-EDS）制图结果初步证实了竹材表面微尺度结构的成功创建，并改善了层次粗糙度。经十八烷基胺（OA）改性后，聚乙烯亚胺(PEI)/PA-Fe3 + /OA/Bamboo表现出优异的超疏水性能，水接触角达到151°，在2 min内保持在150°以上，无明显变化。PEI/PA-Fe3+/OA/Bamboo经过磨损、刮擦和胶带剥离试验后，仍保持了较高的疏水性，水接触角保持在140°以上。最后，植酸基杂化金属配合物在竹子表面形成了致密的保护涂层。这种涂层既可以阻止黑曲霉获取内部营养物质，又可以抑制其在竹表面的粘附。因此，超疏水涂层的成功应用提高了竹材的抗霉性。

Despite growing interest in bamboo’s role in climate mitigation, the influence of elevation on the carbon storage potential of Dendrocalamus hamiltonii in non-forest areas remains poorly understood. To address this gap, we estimated its biomass carbon stock across four elevation zones (200–400 m, 400–600 m, 600–800 m, and 800–1000 m) in areas outside the forest in the Chure region, Central Nepal. Altogether 44 square sample plots, each 100 m² in area, were established. We utilized purposive sampling and non-destructive methods to measure bamboo culm diameters. Soil samples were taken from two soil depths: 0–5 cm and 16–30 cm using soil augers and core samplers. Findings showed a notable difference in average culm diameter, clump density and carbon sequestration potential across the elevation range. Clump density (418 ha⁻¹) and culm diameter (6.02 ± 0.26 cm) were higher at the 400–600 m elevation range. The total average C stock in Dendrocalamus hamiltonii was higher (86.41 M gha⁻¹) at the 400–600 m range, declining to 59.29 Mg ha⁻¹ at the 800–1000 m range. This study showed a significant difference in both aboveground C stock (AGCS) and soil organic carbon (SOC) along different elevation ranges (p < 0.001). Thus the findings highlight the promising role of Dendrocalamus hamiltonii Nees in C stock enhancement for climate mitigation in Nepal.

尽管人们对竹子在减缓气候变化中的作用越来越感兴趣，但海拔对非森林地区哈密顿树（Dendrocalamus hamiltonii）碳储存潜力的影响仍然知之甚少。为了解决这一差距，我们估计了尼泊尔中部Chure地区森林外地区四个海拔区域（200-400 m, 400-600 m， 600-800 m和800-1000 m）的生物量碳储量。共建立44个方形样地，每个样地面积为100 m2。采用目的抽样和非破坏性方法测定竹材直径。土壤样品取自两个土壤深度：0-5 cm和16-30 cm，使用土壤螺旋钻和岩心取样器。结果表明，不同海拔范围内的平均茎粗、丛密度和固碳潜力存在显著差异。400 ~ 600 m海拔范围内，丛密度（418 ha−1）和茎径（6.02 ± 0.26 cm）较高。400 ~ 600 M范围内，哈密石菖蒲总平均碳储量较高（86.41 M ha−1），而800 ~ 1000 M范围内，总平均碳储量为59.29 Mg ha−1。研究结果表明，不同海拔范围的地上碳储量（AGCS）和土壤有机碳（SOC）存在显著差异（p <； 0.001）。因此，这些发现强调了哈密顿树菖蒲在尼泊尔增加碳储量以减缓气候变化方面的有希望的作用。
