In order to avoid the complicated process of capturing carbon dioxide (CO₂) and embedding it underground, a fast CO₂ capture technique that allows for onsite elimination is required. This study investigates the potential of using electric/microwave arc plasma with metals to enhance CO₂ decomposition, which normally does not occur without ionization. The research explores the rapid interactions between various metals and CO₂ under atmospheric pressure. In the experimental setup, metals such as gold, copper, aluminum, magnesium, iron, zinc, titanium, and tungsten are exposed to microwaves to induce arc plasma in a controlled chamber. These interactions are analyzed using advanced characterization techniques such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), Raman spectroscopy, UV–Vis spectroscopy, and photoluminescence (PL) spectroscopy. Gas amount and content are monitored via gas chromatography (GC). The results show that microwave arc plasma effectively disintegrates CO₂, converting it into carbon and carbide. With rapid CO₂ disintegration and metal-induced carbon separation, several metals can be used. While Titanium (Ti) exhibited the fastest reduction rate, Tungsten (W) was identified as the most durable candidate due to its superior thermal stability and resistance to degradation. These findings suggest that electric/microwave arc plasma technology presents a promising and efficient method for CO₂ reduction, with potential implications for climate change mitigation strategies.

为了避免捕获二氧化碳并将其埋入地下的复杂过程，需要一种能够现场消除的快速二氧化碳捕获技术。这项研究探讨了使用电/微波电弧等离子体与金属来增强二氧化碳分解的潜力，这通常不会在没有电离的情况下发生。该研究探索了大气压力下各种金属与二氧化碳之间的快速相互作用。在实验装置中，金、铜、铝、镁、铁、锌、钛和钨等金属在受控室中暴露于微波中以诱导电弧等离子体。这些相互作用分析使用先进的表征技术，如扫描电子显微镜（SEM），透射电子显微镜（TEM），能量色散x射线光谱学（EDX），拉曼光谱，紫外-可见光谱，光致发光（PL）光谱。气相色谱法（GC）监测气体量和含量。结果表明，微波电弧等离子体能有效分解CO2，将其转化为碳和碳化物。随着二氧化碳的快速分解和金属诱导的碳分离，可以使用几种金属。钛（Ti）表现出最快的还原速率，而钨(W)由于其优异的热稳定性和抗降解性而被认为是最耐用的候选材料。这些发现表明，电/微波电弧等离子体技术是一种有前景的、有效的二氧化碳减排方法，对减缓气候变化战略具有潜在影响。

Shotcrete is a critical lining material for tunnel constructions. However, previous studies have struggled to simultaneously achieve excellent workability, rapid-setting, high early-strength and superior toughness. Inspired by nest-building behavior of canaries, this study integrates in-situ polymerization with the alkali-free accelerator (AC) to rapidly construct an organic–inorganic skeleton and optimize early-age performance. The results indicated that in-situ polymerization improved the workability of the mortar within 1 h. Hydration kinetic analysis demonstrated that AC promoted ettringite formation and released heat, triggering monomer polymerization. The polymerization process further enhanced cement hydration, generating a mutual activation effect. This synergy reduced the percolation threshold, significantly shortening the setting time. The accelerated hydration subsequently produced “mud-like” hydration products that filled the pore structure, resulting in a denser matrix. Consequently, the 6 h compressive strength reached 2.7 MPa, representing an 800 % increase compared with the Con, and the flexural strength exhibited remarkable improvements of 400 %, 84 %, and 22 % after 6 h, 1 d and 28 d of hydration, respectively. This study provides a novel strategy for designing high-performance shotcrete and promoting the high-quality development of tunnel constructions.

喷射混凝土是隧道施工中重要的衬砌材料。然而，以往的研究一直在努力同时实现优异的加工性、快速凝固、高早期强度和优异的韧性。受金丝雀筑巢行为的启发，本研究将原位聚合与无碱促进剂（AC）相结合，快速构建有机-无机骨架并优化早期性能。结果表明，原位聚合在1 h内改善了砂浆的和易性。水化动力学分析表明，AC促进钙矾石形成并释放热量，引发单体聚合。聚合过程进一步增强了水泥水化，产生了相互活化的效果。这种协同作用降低了渗透阈值，显著缩短了凝固时间。加速的水化作用随后产生“泥状”水化产物，填充孔隙结构，形成更致密的基质。结果表明，6 h抗压强度达到2.7 MPa，比Con提高了800%，水化6 h、1 d和28 d后，抗弯强度分别提高了400%、84%和22%。本研究为设计高性能喷射混凝土，促进隧道施工的高质量发展提供了新的策略。

Global CO₂ emissions, exceeding 40 billion tonnes annually, drive critical ecological challenges, necessitating effective mitigation strategies like carbon capture, utilization, and storage (CCUS). CO₂ mineralization, a promising CCUS pathway, utilizes alkali-rich industrial wastes such as carbide slag (CS) to form stable carbonate minerals, ensuring permanent CO₂ sequestration with minimal leakage risks. CS, primarily composed of Ca(OH)₂, offers high alkalinity and calcium content, making it an ideal precursor for CO₂ mineralization. Various carbonation methods, including direct, indirect and advanced techniques, could produce construction materials, high-value nano-calcium carbonates and energy storage solutions. Operational parameters such as temperature, concentration, humidity, and additives significantly influence carbonation efficiency and product properties. Direct carbonation yields CaCO₃ suitable for large-scale industrial uses, while indirect and advanced methods enhance product purity and functionality for specialized applications. This integration sequesters CO₂ while producing valuable by-products, thereby enhancing economic viability. This article provides a comprehensive analysis of CS carbonation mechanisms, methods, and applications, emphasizing the interplay between process parameters and product outcomes to optimize sustainable CO₂ management and material innovation.

全球二氧化碳排放量每年超过400亿吨，造成严重的生态挑战，需要采取有效的减缓战略，如碳捕集、利用和封存（CCUS）。二氧化碳矿化是一种很有前途的CCUS途径，它利用电石渣（CS）等富含碱的工业废料形成稳定的碳酸盐矿物，以最小的泄漏风险确保二氧化碳的永久封存。CS主要由Ca(OH)2组成，具有较高的碱度和钙含量，是理想的CO2矿化前体。各种碳化方法，包括直接、间接和先进的技术，可以生产建筑材料、高价值的纳米碳酸钙和储能解决方案。操作参数，如温度、浓度、湿度和添加剂显著影响碳化效率和产品性能。直接碳化生产CaCO3适用于大规模工业用途，而间接和先进的方法提高产品纯度和功能的专门应用。这种整合在产生有价值的副产品的同时隔离了二氧化碳，从而提高了经济可行性。本文全面分析了CS碳化的机理、方法和应用，强调了工艺参数和产品结果之间的相互作用，以优化可持续的二氧化碳管理和材料创新。

Lithium slag (LS) demonstrates synergistic reactivity and element complementarity in cement systems. However, LS exhibits low pozzolanic reactivity when blended with ordinary Portland cement (PC). This study designed a new kind of cleaner cementitious material via solid-waste and low-alkalinity activation. Four possible low-alkali activators were investigated: calcium aluminate (CA), sodium aluminosilicate (SS), sodium carbonate (SC), and sodium aluminate (SA), as well as their combinations for activating high-volume lithium slag cement (HVLSC) via microstructural evolution. Results indicate that the SS–SA considerably enhances C–(A)–S–H and N–A–S–H co-gel formation and promotes ettringite (AFt) nucleation, increasing compressive strength by 306 %, 123 %, and 108 % after 7, 14, and 21 days, respectively. The SC activator reduces fluidity in SC systems because CO₃²⁻ induces CaCO₃ precipitation. The SS–SA exhibits the best strength enhancing effect by leveraging the synergy of the Na⁺–SiO₃²⁻–AlO₂⁻ ternary system. This synergy optimizes the density of the gel network and considerably enhances the strength of HVLSC and reduces CO₂ emissions per unit strength by 52.2 % of the carbon dioxide emission per unit strength.

锂渣（LS）在水泥体系中表现出协同反应性和元素互补性。与普通硅酸盐水泥（PC）混合后，LS表现出较低的火山灰反应性。本研究设计了一种采用固废低碱度活化的新型清洁胶凝材料。研究了四种可能的低碱活化剂：铝酸钙（CA）、铝硅酸钠（SS）、碳酸钠（SC）和铝酸钠（SA），以及它们通过微观结构演化对高容量锂渣水泥（HVLSC）的活化作用。结果表明，SS-SA显著增强了C - (A) - s - h和N-A-S-H共凝胶的形成，促进钙矾石（AFt）成核，在7、14和21天后，抗压强度分别提高了306%、123%和108%。由于CO32−诱导CaCO3沉淀，SC活化剂降低了SC体系的流动性。利用Na+ -SiO32−-AlO2−三元体系的协同作用，SS-SA表现出最佳的强度增强效果。这种协同作用优化了凝胶网络的密度，大大提高了HVLSC的强度，并将单位强度的二氧化碳排放量降低了52.2%。

Although natural and recycled fibre-based insulation materials show promising thermal and acoustic performance, several challenges still limit their widespread adoption. This paper explores the properties and potential of recycled textile and natural fiber-based materials in enhancing building renovations. Specifically, it examines two types of insulation panels: those made from recycled textiles (Panels M) and those composed of kenaf and hemp fibers (Panels K). The study investigates various properties, including composition, density, thermal conductivity, acoustic performance, and fire response, highlighting the strengths and challenges associated with each material. The results reveal that while textile-based panels exhibit more variability in composition and performance, natural fiber panels are more uniform, making them a more predictable and reliable option. Thermal conductivity values ranged from 0.035 to 0.049 W/(m·K), with the natural fiber panels showing more consistent results. Acoustic performance, evaluated using both Sonocat sensor and the impedance tube also varied, with textile-based panel M45 performing particularly well approaching the Basotect performance (this latter used as a functional benchmark). Fire response, tested using Temperature Programmed Oxidation (TPO), indicated that kenaf-based panels demonstrated higher flammability compared to their textile counterparts. Furthermore, the study explored the effectiveness of fire retardants, finding that certain treatments helped suppress ignition.

尽管天然和再生纤维基绝缘材料表现出良好的热学和声学性能，但一些挑战仍然限制了它们的广泛应用。本文探讨了再生纺织品和天然纤维基材料在加强建筑改造方面的性能和潜力。具体来说，它检查了两种类型的绝缘板：由回收纺织品制成的（板M）和由红麻和大麻纤维组成的（板K）。该研究调查了各种性能，包括成分、密度、导热性、声学性能和火灾响应，突出了每种材料的优势和挑战。结果表明，虽然基于纺织品的面板在成分和性能上表现出更多的可变性，但天然纤维面板更加均匀，使其成为更可预测和可靠的选择。导热系数范围为0.035 ~ 0.049 W/(m·K)，与天然纤维板的结果更为一致。使用Sonocat传感器和阻抗管评估的声学性能也有所不同，基于纺织品的面板M45的性能特别好，接近Basotect的性能（后者用作功能基准）。使用温度程序化氧化（TPO）测试的火灾反应表明，与同类纺织品相比，红麻基板表现出更高的可燃性。此外，该研究还探讨了阻燃剂的有效性，发现某些处理方法有助于抑制着火。

High-content rubber-modified asphalt (HC-RMA), incorporating over 25 % waste tire rubber powder, delivers environmental sustainability alongside enhanced pavement performance. However, a rubber content exceeding 30 % typically induces excessive viscosity and phase separation. To address these issues, HC-RMA samples were prepared using rubber powder with Mooney viscosities ranging from 40 to 120 MU. Among these, the binder containing 40 % rubber powder with 40 MU viscosity (CR40D) showed a practical viscosity of 1.34 Pa s at 180 °C and demonstrated superior performance, including enhanced high-temperature rutting resistance and improved low-temperature crack resistance. Microscopic analyses (CLSM and AFM) combined with Delaunay triangulation confirmed that the CR40D formulation promoted the formation of a uniform, dense rubber particle network with increased crosslinking density. Molecular dynamics (MD) simulations identified a critical rubber content of 40 % by mass, at which optimal binder compatibility and the strongest intermolecular interactions (van der Waals forces up to 5.4 kJ/mol) were observed. Further increases in rubber content led to a notable decline in these interactions. In conclusion, incorporating 40 % low-Mooney-viscosity (40 MU) rubber powder optimizes the performance of HC-RMA. The resulting material is a high-performance, cost-effective, and eco-friendly paving binder with strong potential for sustainable road construction.

高含量橡胶改性沥青（HC-RMA），含有超过25%的废轮胎橡胶粉，在提高路面性能的同时实现了环境的可持续性。然而，橡胶含量超过30%通常会导致过度的粘度和相分离。为了解决这些问题，HC-RMA样品的制备使用了黏度为40 - 120 MU的胶粉。其中，含有40%黏度为40 MU的胶粉（CR40D）的粘结剂在180℃时的实际黏度为1.34 Pa s，表现出优异的性能，包括增强了高温车辙性能和提高了低温抗裂性能。微观分析（CLSM和AFM）结合Delaunay三角测量证实，CR40D配方促进了均匀、致密的橡胶颗粒网络的形成，并增加了交联密度。分子动力学（MD）模拟发现，当橡胶质量比为40%时，粘合剂相容性最佳，分子间相互作用最强（范德瓦尔斯力高达5.4 kJ/mol）。橡胶含量的进一步增加导致这些相互作用的显著下降。综上所述，添加40%低穆尼粘度（40 MU）的胶粉可优化HC-RMA的性能。由此产生的材料是一种高性能，具有成本效益和环保的铺装粘合剂，具有可持续道路建设的强大潜力。

The chitinous fibrous network of mycelium has recently been implemented as a sustainable packaging or leather alternative. Other endeavors are currently explored given the environmentally friendly biofabrication process, suitable mechanics, flame resistance, and insulative properties. In this proof-of-concept study, we explore the potential of mycelium (Pleurotus ostreatus) to form bio-blocks by propagating across cotton, polyester, and mixed shredded textile fabrics (MSTF). Biocomposites showed distinct colonization patterns as a function of inoculation condition and textile type. Cotton-based composites demonstrated good structural integrity, reaching a flexural strength of 82.5 kPa and a toughness of 3298 kJm⁻³. Polyester-based composites exhibited a similar flexural strength of 80.5 kPa but showed nearly half the toughness at 1414 kJ/m⁻³. Flammability tests revealed flame extinction after 30 s in cotton composites, with 40 % of the area burned, whereas polyester composites reduced the combustion rate by 76 %. A comprehensive life cycle assessment (LCA) focusing on environmental impacts shows a cradle-to-gate commercial-scale climate change potential of 0.05 and 4.28 kg-CO₂-equiv per kilogram of biobrick considering renewable-based and fossil-based energy mix scenarios, respectively. Our findings establish mycelium as an effective binding agent for textiles towards the formation of materials with complex forms benefiting from the inherent attributes of textiles.

菌丝体的几丁质纤维网络最近被用作可持续包装或皮革替代品。考虑到环境友好的生物制造工艺、合适的力学、阻燃性和绝缘性能，目前正在探索其他的努力。在这项概念验证研究中，我们探索了菌丝体（Pleurotus ostreatus）通过在棉花、聚酯和混合碎纺织品（MSTF）上繁殖形成生物块的潜力。不同接种条件和纺织品类型对复合材料的定殖模式有不同的影响。棉基复合材料具有良好的结构完整性，抗弯强度达到82.5 kPa，韧性达到3298 kkm−3。聚酯基复合材料的抗弯强度为80.5 kPa，但在1414 kJ/m−3时的韧性几乎是前者的一半。可燃性测试表明，棉复合材料在30秒后火焰熄灭，燃烧面积为40%，而聚酯复合材料的燃烧率降低了76%。一项关注环境影响的综合生命周期评估（LCA）显示，考虑到可再生能源和化石能源组合情景，生物砖从摇篮到大门的商业规模气候变化潜力分别为0.05千克和4.28千克二氧化碳当量。我们的研究结果表明，菌丝体是一种有效的结合剂，有利于纺织品形成具有复杂形式的材料，这得益于纺织品的固有属性。

Porous carbon fibers offer high specific surface area, rapid adsorption kinetics, and excellent structural durability, making them attractive for environmental and energy-related applications. However, converting polyolefin-based precursors such as high-density polyethylene into carbon fibers is challenging because severe structural collapse often occurs during carbonization. In this study, we propose a three-step stabilization strategy consisting of electron-beam irradiation, sulfonation, and phosphorylation, which enhances thermal stability and enables the formation of uniformly crosslinked fibers throughout the fiber cross section. Thermogravimetric analysis showed that the multi-acid stabilization produced a char yield comparable to that obtained by sulfuric-acid-only treatment (47.36% vs. 47.41% at 800℃). Tensile strength measurements after carbonization revealed that fibers treated with the multi-acid stabilization method exhibited approximately a 40% improvement compared to sulfonation-only fibers. Microstructural analyses using SEM, Raman spectroscopy, and XRD confirmed suppressed core collapse, reduced defect gradients, and improved crystallite ordering, which collectively facilitated enhanced mesopore development in the resulting porous carbon fibers.

多孔碳纤维具有高比表面积，快速吸附动力学和优异的结构耐久性，使其在环境和能源相关应用中具有吸引力。然而，将聚烯烃为基础的前体（如高密度聚乙烯）转化为碳纤维是具有挑战性的，因为在碳化过程中经常发生严重的结构崩溃。在这项研究中，我们提出了一种由电子束照射、磺化和磷酸化组成的三步稳定化策略，该策略增强了热稳定性，并使整个纤维截面上形成均匀交联的纤维。热重分析表明，多酸稳定法的焦炭产率与单酸稳定法相当（分别为47.36%和47.41%）。碳化后的拉伸强度测试表明，与磺化纤维相比，采用多酸稳定方法处理的纤维的拉伸强度提高了约40%。利用SEM、拉曼光谱和XRD进行的微观结构分析证实，该材料抑制了核心坍塌，降低了缺陷梯度，改善了晶体的有序性，这些共同促进了多孔碳纤维中孔的发育。

Cement-free construction materials are essential to reduce global carbon emissions, yet scalable alternatives remain limited. We report the development of a lignin-based biopolymer-bound soil composite (BSC), a novel cement-free material with mechanical properties comparable to lightweight concrete. To advance its scalability and environmental performance, we also used a systematic framework for solvent selection in lignin biocomposite fabrication. Applying this approach, we identified an acetic acid–water solvent system that speeds up manufacturing and enhances material quality. BSCs fabricated with this system exhibit increased strength (5.4 MPa vs. 3.7 MPa), attributed to acetylation of lignin. In addition, the acetic acid–water system dramatically reduces drying time compared with the alternative solvent, dimethyl sulfoxide (2 days vs. 14 days), enabling more efficient production. Life cycle assessment reveals additional CO

) relative to lignin biocomposite made using DMSO as the solvent. These improvements stem from solvent-induced modifications in lignin chemistry that enhance composite performance.

无水泥建筑材料对减少全球碳排放至关重要，但可扩展的替代品仍然有限。我们报告了木质素基生物聚合物结合土壤复合材料（BSC）的发展，这是一种新型无水泥材料，具有与轻质混凝土相当的机械性能。为了提高其可扩展性和环境性能，我们还使用了木质素生物复合材料制造中溶剂选择的系统框架。应用这种方法，我们确定了一种醋酸-水溶剂系统，可以加快生产速度并提高材料质量。由于木质素的乙酰化，用该体系制备的BSCs具有更高的强度（5.4 MPa vs 3.7 MPa）。此外，与替代溶剂二甲亚砜相比，乙酸-水系统显著缩短了干燥时间（2天vs. 14天），从而提高了生产效率。生命周期评估显示，与使用DMSO作为溶剂的木质素生物复合材料相比，额外的二氧化碳封存和材料成本降低70%（122-237美元/立方米，而409-933美元/立方米）。这些改进源于溶剂诱导的木质素化学修饰，增强了复合材料的性能。这项工作展示了材料设计和合理的溶剂选择如何为采用木质素基复合材料铺平道路，使其成为建筑环境中可扩展的、负担得起的低碳替代品。

This paper presents a detailed review of wood-cement composites, focusing on their material characteristics, mechanical performance, and evolution as a class of sustainable and cleaner construction material. Formed by combining wood particles with cementitious binders, these composites offer a unique alternative to conventional building materials by utilising renewable resources, supporting cleaner production practices, and reducing embodied carbon. The review is based on an extensive compilation of experimental data drawn from the literature, covering a wide range of studies that examine the effects of wood species, binder types, fabrication methods, and testing protocols on composite performance. Particular attention is given to the influence of binder composition, wood particle size, and mix ratios on key mechanical properties, including compressive strength, flexural strength, density, and toughness. These parameters are critically assessed to establish their role in governing the structural reliability and functional suitability of the composites. The review also addresses production techniques and standardised testing methods, identifying common challenges such as the chemical incompatibility between lignocellulosic materials and cement hydrates, and summarising approaches developed to mitigate these issues. Recent developments, including the use of alkali-activated binders, are examined for their potential to enhance material performance and support cleaner material development. By consolidating existing research and identifying gaps in current knowledge, this paper aims to support further technical advancement and inform the practical implementation of wood-cement composites in environmentally responsible construction.
