The development of sustainable and high-performance phase change materials (PCMs) is essential for efficient thermal energy storage and management. In this work, pine wood and balsa wood were used as biomass precursors to fabricate porous carbon matrices through delignification, chemical activation, and carbonization. Polyvinyl alcohol (PVA) was introduced to reinforce the carbon framework and improve structural stability, while polyethylene glycol (PEG-4000) served as the phase change medium. The resulting shape-stabilized composite PCMs were systematically characterized using SEM, BET, FTIR, XRD, DSC, TGA, and thermal conductivity measurements

The SEM and BET analyses revealed that activation and carbonization significantly enhanced pore connectivity and surface area, providing efficient pathways for PEG impregnation. FTIR spectra confirmed physical encapsulation and hydrogen bonding interactions between PEG and the carbon matrix. DSC results demonstrated that the composites exhibited high latent heat values (up to 138.23 kJ·kg⁻¹) and stable melting–solidification behavior, with minimal influence from PVA content. Balsa-derived composites showed higher enthalpy and thermal conductivity (0.55 W·m⁻¹·K⁻¹) than pine-derived counterparts due to their more ordered porous structures. TGA results indicated improved thermal stability, with decomposition temperatures increasing from 194 °C for pure PEG to above 300 °C for the composites.

Overall, the incorporation of biomass-derived porous carbon effectively suppressed leakage, enhanced thermal conductivity, and maintained high latent heat storage, demonstrating strong potential for eco-friendly and durable thermal energy storage applications.

可持续和高性能相变材料（PCMs）的发展对于高效的热能储存和管理至关重要。本研究以松木和巴尔沙木作为生物质前体，通过脱木质素、化学活化和炭化制备多孔碳基质。引入聚乙烯醇（PVA）增强碳骨架，提高结构稳定性，聚乙二醇（PEG-4000）作为相变介质。通过SEM、BET、FTIR、XRD、DSC、TGA和导热系数等测试手段对所制备的形状稳定的复合PCMs进行了系统表征。SEM和BET分析表明，活化和碳化显著增强了孔隙连通性和比表面积，为PEG的浸渍提供了有效的途径。FTIR光谱证实了PEG与碳基体之间的物理封装和氢键相互作用。DSC结果表明，复合材料具有高潜热值（高达138.23 kJ·kg⁻）和稳定的熔融凝固行为，PVA含量的影响最小。巴尔沙衍生的复合材料由于其更有序的多孔结构，比松树衍生的复合材料表现出更高的焓和导热性（0.55 W·m⁻¹·K⁻）。TGA结果表明，复合材料的热稳定性得到改善，分解温度从纯PEG的194°C提高到300°C以上。总体而言，生物质衍生多孔碳的掺入有效地抑制了泄漏，增强了导热性，并保持了高潜热储存，显示出强大的生态友好和持久的热能储存应用潜力。

Luffa cylindrica fiber is widely used as an adsorbent for contaminants in water, but after use, it becomes chemical waste. This study investigates the thermal degradation of Luffa biomass after its modification with potential pollutants. The fiber was pretreated with saline water or diesel oil to simulate contamination and was compared to a reference fiber washed with deionized water. After drying, the samples were characterized using SEM/EDS microscopy. Subsequently, they underwent slow pyrolysis through thermogravimetric analysis and rapid micro-pyrolysis at 873 K. Thermogravimetric results under nitrogen indicate that these pretreatments affect the samples’ decomposition profiles. The presence of inorganic salts caused a slight catalytic effect during the decomposition of hemicellulose and cellulose under nitrogen, reducing the maximum peak decomposition temperature of hemicellulose by 38 K. Inorganic salts also exhibited inhibitory effects during the high-temperature combustion of biochar formed. In diesel-contaminated biomass, diesel can be practically removed without transformation before the Luffa fiber components begin to decompose at higher temperatures. The possibility of recovering an important fraction of diesel oil was also demonstrated in the micro-pyrolysis results. This study confirms that different pretreatments significantly affect Luffa decomposition mechanisms, suggesting that, in studies of biomass transformation, researchers must consider that initial cleaning processes can generate sample modifications. This method is also helpful for assessing the reuse of spent Luffa biomass for bioenergy generation.

丝瓜纤维作为水中污染物的吸附剂被广泛使用，但使用后成为化学废弃物。研究了丝瓜生物质经潜在污染物改性后的热降解情况。用盐水或柴油对纤维进行预处理以模拟污染，并与用去离子水洗涤的参考纤维进行比较。干燥后，用SEM/EDS显微镜对样品进行表征。随后，通过热重分析缓慢热解，并在873 K下进行快速微热解。氮下的热重分析结果表明，这些预处理对样品的分解曲线有影响。无机盐的存在对半纤维素和纤维素在氮气条件下的分解有轻微的催化作用，使半纤维素的最高分解峰温度降低了38 K。无机盐在生物炭高温燃烧过程中也表现出抑制作用。在柴油污染的生物质中，在丝瓜纤维成分在较高温度下开始分解之前，柴油实际上可以在不转化的情况下被去除。微热解结果也证明了回收柴油重要组分的可能性。本研究证实，不同的预处理对丝瓜的分解机制有显著影响，这表明，在生物质转化的研究中，研究人员必须考虑到初始清洗过程可能会产生样品修饰。该方法也有助于评估废弃丝瓜生物质用于生物能源发电的再利用。

Gold nanoparticles based on localized surface plasmon resonance (LSPR) have been widely used in solar energy applications due to their excellent photothermal conversion properties. However, conventional nanostructures exhibit single-peak spectral responses and limited photothermal conversion efficiency, necessitating structural innovations to overcome the inherent limitations. Therefore, we have designed a novel class of framework-confined Au based nanocomposite structures. Compared with their mono-dispersions (cubic frame, nanosphere, and nanocylinder), the photothermal responses of framework-confined nanoparticles in the wavelength range of 300–1100 nm are significantly improved. In particular, the photothermal conversion efficiency of framework-confined nanocylinders is as high as 92.2 %. Electromagnetic field analysis shows that a framework with a tip structure coupled to an internal monomer achieves a multimodal surface plasmon resonance, leading to significant absorption. This work provides valuable insights into the design of nanoparticles with different conversion.

基于局域表面等离子体共振（LSPR）的金纳米粒子由于其优异的光热转换性能，在太阳能领域得到了广泛的应用。然而，传统的纳米结构表现出单峰光谱响应和有限的光热转换效率，需要结构创新来克服固有的局限性。因此，我们设计了一类新型的框架约束金基纳米复合材料结构。在300 ~ 1100 nm波长范围内，与单分散体（立方体框架、纳米球和纳米圆柱）相比，框架约束的纳米颗粒光热响应显著提高。其中，框架约束纳米柱的光热转换效率高达92.2%。电磁场分析表明，具有尖端结构的框架与内部单体耦合，实现了多模态表面等离子体共振，导致显著的吸收。这项工作为设计具有不同转化率的纳米颗粒提供了有价值的见解。

Osteoporotic fracture healing is orchestrated by the dynamic interplay between osteoblasts and osteoclasts, with microRNAs (miRNAs) serving as pivotal regulators of bone metabolism. This study aimed to elucidate the role of miR-34a-5p in osteoporotic fracture repair and its underlying molecular mechanisms. In vitro investigations demonstrated that miR-34a-5p suppresses osteoclast differentiation by directly targeting Foxp1, while concurrently mitigating Foxp1-mediated inhibition of osteoblast differentiation. Transcriptomic profiling of MC3T3-E1 osteoblasts, revealed that miR-34a-5p modulates osteoblast differentiation predominantly via the Hippo/YAP signaling axis, a finding further corroborated by Western blot, underscoring its central role in osteogenic regulation. In an ovariectomized (OVX) mouse femoral fracture model, local administration of miR-34a-5p mimics at the fracture site markedly accelerated bone repair. Micro-CT assessment demonstrated significant enhancement in bone volume and trabecular microarchitecture, while histological evaluations confirmed the expedited progression of bone regeneration. Collectively, these findings establish that miR-34a-5p orchestrates osteoblast and osteoclast activity through Foxp1 targeting and directly promotes osteoblast differentiation via the Hippo/YAP pathway, providing mechanistic insights and identifying potential therapeutic targets for miRNA-based strategies in bone repair.

骨质疏松性骨折愈合是由成骨细胞和破骨细胞之间的动态相互作用精心策划的，而microrna （mirna）是骨代谢的关键调节因子。本研究旨在阐明miR-34a-5p在骨质疏松性骨折修复中的作用及其潜在的分子机制。体外研究表明，miR-34a-5p通过直接靶向Foxp1抑制破骨细胞分化，同时减轻Foxp1介导的成骨细胞分化抑制。MC3T3-E1成骨细胞的转录组学分析显示，miR-34a-5p主要通过Hippo/YAP信号轴调节成骨细胞分化，Western blot进一步证实了这一发现，强调了其在成骨调节中的核心作用。在去卵巢（OVX）小鼠股骨骨折模型中，在骨折部位局部给予miR-34a-5p模拟物可显著加速骨修复。显微ct评估显示骨体积和小梁微结构显著增强，而组织学评估证实骨再生加速进展。总之，这些发现表明miR-34a-5p通过Foxp1靶向调控成骨细胞和破骨细胞的活性，并通过Hippo/YAP通路直接促进成骨细胞分化，为基于mirna的骨修复策略提供了机制见解并确定了潜在的治疗靶点。

This research explores the incorporation of thermally activated tuff powder (ATP) into cementitious materials, with the aim of clarifying the mechanisms of microstructural reconstruction, improving pozzolanic reactivity, and establishing the link between tuff’s microstructural transformation and its pozzolanic behavior. The results indicate that the optimal thermal activation parameter for tuff is an activation temperature of 800 °C, under which the compressive strength of the cement-based material reaches 56.1 MPa, with an activity index of 106.3 %. The thermal activation process disrupts the crystalline phases in TF, promoting the dehydroxylation of silicate minerals and releasing highly reactive materials while significantly increasing the specific surface area, thereby providing more active sites for pozzolanic reactions. This study offers a theoretical basis and technical guidance for the efficient utilization of tuff resources and the development of high-performance supplementary cementitious materials (SCMs), thereby promoting the sustainable and performance-oriented advancement of cement-based materials.

本研究将热活化凝灰岩粉（ATP）掺入胶凝材料中，旨在阐明凝灰岩微结构改造的机理，提高凝灰岩的反应性，建立凝灰岩微结构改造与凝灰岩行为之间的联系。结果表明：凝灰岩的最佳热活化参数为活化温度为800℃，在此温度下，水泥基材料的抗压强度达到56.1 MPa，活性指数为106.3%；热活化过程破坏了TF中的结晶相，促进了硅酸盐矿物的去羟基化，释放出高活性物质，同时显著增加了比表面积，从而为火山灰反应提供了更多的活性位点。本研究为凝灰岩资源的高效利用和高性能补充胶凝材料（SCMs）的开发提供理论依据和技术指导，从而促进水泥基材料的可持续和高性能化发展。

Traditional composite phase change materials suffer from issues such as leakage and insufficient flexibility, which significantly impair their performance in human skin temperature regulation and wearable thermal management applications. This study employs a sol-gel synergistic method to integrate n-octadecane, n-decanoic acid, and a three-dimensional styrene-ethylene-butylene-styrene (SEBS) elastic network. This method results in the development of a phase change gel that combines leak-proof properties with flexibility. The SEBS framework securely locks the eutectic material within microscale pores, allowing the energy storage gel to maintain its integrity at temperatures as high as 80 °C. The material exhibits excellent tensile and compressive strengths, with stress values as high as 1.108 MPa and 1.120 MPa, respectively. This ensures that the material can deform freely without breaking when applied to the skin. In practical applications on human skin, the temperature of the wrist without the gel reached 45 °C within 120 s and continued to rise. In contrast, the temperature in the wearing area increased significantly more slowly, maintaining approximately 32 °C at 220 s and showing a noticeable temperature increase only after 600 s. These results demonstrate the material's excellent temperature control and insulation performance. This research has promising applications in high-temperature environments and localized thermal buffering.

传统的复合相变材料存在渗漏和柔韧性不足等问题，严重影响了其在人体皮肤温度调节和可穿戴热管理方面的应用。本研究采用溶胶-凝胶协同的方法将正十八烷、正癸酸和三维苯乙烯-乙烯-丁烯-苯乙烯（SEBS）弹性网络进行整合。这种方法可以开发出一种结合了防泄漏性能和灵活性的相变凝胶。SEBS框架将共晶材料安全地锁定在微孔内，使储能凝胶在高达80°C的温度下保持其完整性。该材料具有优异的抗拉和抗压强度，应力值分别高达1.108 MPa和1.120 MPa。这确保了材料在应用于皮肤时可以自由变形而不会断裂。在人体皮肤上的实际应用中，没有凝胶的手腕温度在120秒内达到45℃并持续上升。相比之下，磨损区域的温度升高明显要慢得多，在220秒时保持在32℃左右，仅在600秒后才出现明显的温度升高。这些结果表明该材料具有良好的温度控制和绝缘性能。该研究在高温环境和局部热缓冲方面具有很好的应用前景。

Understanding the mechanistic details of diesel particulate matter (DPM) oxidation is essential for optimising the regeneration process of diesel particulate filters (DPF). This study aimed to investigate the kinetics of DPM oxidation accelerated by Ag/Al₂O₃. Experiments were conducted using thermogravimetric analysis (TGA) at different heating rates. The activation energy was determined using the isoconversional method, the multi-step reaction was identified using the peak deconvolution technique, and the reaction models were selected using the master plot approach. The results revealed a multi-step transformation process with activation energies of 50–130 kJ/mol. The main role of Ag/Al₂O₃ was to supply active oxygen for light VOCs and to facilitate O₂ transport from the gas stream to the heavy VOCs sites.

了解柴油颗粒物质（DPM）氧化的机理细节对于优化柴油颗粒过滤器（DPF）的再生过程至关重要。研究了Ag/Al₂O₃加速DPM氧化的动力学。采用热重分析（TGA）对不同升温速率下的样品进行了实验。采用等转换法确定活化能，采用峰反褶积法识别多步反应，采用主图法选择反应模型。结果表明，这是一个多步转化过程，活化能在50 ~ 130 kJ/mol之间。Ag/Al₂O₃的主要作用是为轻VOCs提供活性氧，并促进O₂从气流向重VOCs部位的输送。对于固体碳的氧化，催化剂促进了活性氧的形成，改善了催化氧化反应机理。这项动力学研究为DPM的氧化行为提供了见解，有助于设计高效的DPF。

The temperature memory effect (TME) in MnCo_0.97Fe_0.03Ge shape memory alloy, fabricated as pellets via arc-melting, has been investigated once the martensite phase was stabilized at room temperature. The results revealed that TME appears during the reverse transformation of thermally induced martensite after incomplete transformation cycling, spanning the entire interval between the austenite start and finish temperatures. Although the reverse transformation temperature range can be broadened by kinetic interruption, restoring the sample to its relaxed state requires the completion of the transformation up to higher temperatures. This necessity must be considered for practical potential uses of these alloys as shape memory applications.

研究了电弧熔炼球团法制备的MnCo0.97Fe0.03Ge形状记忆合金在室温稳定马氏体后的温度记忆效应（TME）。结果表明，在不完全转变循环后的热诱导马氏体反向转变过程中出现了TME，并跨越了奥氏体开始和结束温度之间的整个区间。虽然通过动力学中断可以扩大反向转变的温度范围，但将样品恢复到松弛状态需要在更高的温度下完成转变。这种必要性必须考虑到这些合金作为形状记忆应用的实际潜在用途。

A concise power law reaction kinetic expression of reversible crystallization phase change was presented for use in global modelling of crystallization and nucleation kinetics of solid-liquid phase change materials (PCMs). This was developed as a closed form, wholly mechanistic expression of phase change kinetics essential to predict coupled heat-mass latent heat evolution in PCMs. This constituted a significant departure from the semi-empirical and phenomenological formulations that have so far dominated PCM sciences. Notably, the presented formulation expresses relative mass supersaturation as the fundamental driving force for phase change as opposed to relying on supercooling degree or temperature rate. In contrast to practice in the industrial crystallization process industry, it was postulated that crystal size population balances could be neglected in PCMs used for thermal storage due to averaging effects of crystal size population balances since the rates of latent heat evolution and heat transport are exclusively prioritized rather than yield of a desired crystal size.

A favourable formulation of the global power law crystallization kinetic model was obtained through evaluation against the 0D transient reference case derived from the cooling curve of manually seeded crystallization of 11 K supercooled 38.1 %mass NaCHO₂ aqueous solution, yielding NaCHO₂•3H₂O(s), under development as a cold storage PCM. Values of apparent activation energies of nucleation and crystal growth and their respective pre-exponential rate constants were obtained by least-squares fitting of experimental cooling curve data. The power law kinetic model was also validated under isothermal conditions using the JMAK equation.

本文提出了可逆结晶相变的幂律反应动力学简明表达式，用于固-液相变材料结晶和成核动力学的全局建模。这是一种封闭形式，完全机械的相变动力学表达，对于预测PCMs中耦合热-质量潜热演变至关重要。这构成了对迄今为止主导PCM科学的半经验和现象学公式的重大背离。值得注意的是，所提出的公式表示相对质量过饱和是相变的基本驱动力，而不是依赖于过冷度或温度速率。与工业结晶过程工业的实践相反，由于晶体尺寸种群平衡的平均效应，假设用于储热的pcm中可以忽略晶体尺寸种群平衡，因为潜热演化和热传输的速率是唯一优先考虑的，而不是期望晶体尺寸的产量。通过对11 K过冷38.1%质量的NaCHO2水溶液人工播种结晶生成NaCHO2•3H2O(s)的0D瞬态参考曲线进行评价，得到了一个较好的全局幂定律结晶动力学模型。通过对实验冷却曲线数据的最小二乘拟合，得到了成核和晶体生长的表观活化能及其指数前速率常数。利用JMAK方程在等温条件下验证了幂律动力学模型。

Valorization of petroleum slack wax for sustainable phase change materials with enhanced thermal energy storage 可持续性相变材料中石油松弛蜡的增值研究

This study valorizes slack wax, a petroleum refining byproduct, as a sustainable additive for paraffin-based phase change materials (PCMs). The limited heat storage of paraffin and the high cost of nanoscale additives hinder their application. We characterize composites using a refined T-History methodology, augmented by H-history analysis and polynomial interpolation for enhanced accuracy. Incorporating 20 % slack wax increases latent heat by 21 % (190–230 kJ/kg) while maintaining melting point stability (±0.2 °C). The composite demonstrates a sharper phase transition and excellent cycling stability (<1 % degradation after 15 cycles). Cross-validation of the Y- and H-methods revealed a minimal deviation in latent heat of <2 %, confirming the robustness of our measurements. Although thermal conductivity decreases by 17 %, this is offset by a 90 % cost reduction compared to nano-enhanced PCMs. The waste valorization benefits and high energy density make this material ideal for applications prioritizing storage capacity over rapid discharge, such as solar thermal storage and passive building temperature control. This approach provides a sustainable and economically viable pathway for large-scale PCM production, successfully repurposing industrial waste to advance thermal energy storage.

本研究对石油炼制副产物松弛蜡作为石蜡基相变材料（PCMs）的可持续添加剂进行了评价。石蜡的储热能力有限和纳米添加剂的高成本阻碍了它们的应用。我们使用改进的T-History方法来表征复合材料，并通过H-history分析和多项式插值来增强精度。加入20%的废蜡可增加21%的潜热（190-230 kJ/kg），同时保持熔点稳定性（±0.2°C）。复合材料表现出更明显的相变和优异的循环稳定性（循环15次后降解<； 1%）。Y-和h -方法的交叉验证显示潜热的最小偏差为<； 2%，证实了我们测量的稳健性。虽然导热系数降低了17%，但与纳米增强型PCMs相比，成本降低了90%。废物增值效益和高能量密度使这种材料非常适合优先考虑存储容量而不是快速放电的应用，例如太阳能蓄热和被动式建筑温度控制。这种方法为大规模PCM生产提供了一种可持续和经济可行的途径，成功地重新利用工业废物来推进热能储存。
