Carbon emissions are the main driver of environmental pollution, necessitating urgent solutions. Addressing this issue requires developing efficient and cost-effective energy stability while preventing any rise in emissions. Innovation in technology is essential to accomplishing this objective. Power electronic technologies are extensively used to connect renewable energy sources to the grid reliably and efficiently, aiding in system control and grid decarbonization. However, the high penetration of renewable energy into the grid can lead to serious issues, including power quality deterioration. As a result, the global energy industry is increasingly implementing power quality improvement technology (PQIT) in large-scale renewable energy plants and grid systems to address these challenges. Yet, this transition introduces new challenges and issues. While there have been numerous reviews on PQIT, there is currently no comprehensive review addressing the configurations and energy management schemes of PQIT in the context of renewable integrations and grid decarbonization. To fill this gap, this manuscript presents an in-depth review of state-of-the-art PQITs, including structural analysis, model development, key findings, research gaps, and their applications in grid integration and decarbonization. This review specifically investigates how various PQIT structural configurations and control algorithms contribute to decarbonization targets. By mapping each technology’s operational role to key decarbonization outcomes, such as reduced emissions, improved energy efficiency, and enhanced renewable integration, the paper establishes a structured connection between technical developments in PQIT and their impact on grid sustainability. The overall discussion, analysis, identification of concerns, and recommendations aim to provide engineers, industries, and stakeholders with insightful information and suggestions for further research regarding the emerging possibilities of PQITs in grid decarbonization.
碳排放是造成环境污染的主要原因,需要紧急解决。要解决这一问题,就需要在防止排放增加的同时,发展高效和具有成本效益的能源稳定。技术创新对实现这一目标至关重要。电力电子技术被广泛用于将可再生能源可靠、高效地接入电网,有助于系统控制和电网脱碳。然而,可再生能源在电网中的高度渗透可能导致严重的问题,包括电能质量恶化。因此,全球能源行业越来越多地在大型可再生能源工厂和电网系统中实施电能质量改进技术(PQIT)来应对这些挑战。然而,这种转变带来了新的挑战和问题。虽然已经有很多关于PQIT的评论,但目前还没有针对可再生能源整合和电网脱碳背景下PQIT的配置和能源管理方案的全面评论。为了填补这一空白,本文对最先进的pqit进行了深入的回顾,包括结构分析、模型开发、关键发现、研究空白以及它们在电网集成和脱碳中的应用。本文专门研究了各种PQIT结构配置和控制算法如何有助于脱碳目标。通过将每种技术的操作作用映射到关键的脱碳结果,例如减少排放、提高能源效率和增强可再生能源整合,本文在PQIT的技术发展及其对电网可持续性的影响之间建立了结构化的联系。全面的讨论、分析、问题识别和建议旨在为工程师、行业和利益相关者提供有见地的信息和建议,以进一步研究pqit在电网脱碳中的新兴可能性。

Molecular property prediction is at the core of machine learning (ML)-driven materials and drug discovery. Effectively navigating the ML workflow requires careful consideration of molecular representations, input preparation strategies, and model architectures. This review aims to provide an intuitive understanding of information processing and input construction in different machine learning models, offering guidance on how different ML approaches align with various prediction tasks and molecular representations. The methodologies are broadly categorized into descriptor-based, string-based, and graph-based models, with greater emphasis placed on graph-based approaches due to their superior ability to capture molecular structure and spatial geometry. Within the string-based category, focus is given to transformers and large language models (LLMs), which are gaining increasing attention owing to their success in natural language processing (NLP). Among graph-based models, the emerging class of geometric graph neural networks (Geometric GNNs) is discussed in detail, as these models represent the current state of the art across multiple benchmark datasets in molecular property prediction.

Recent studies on developing in manufacturing processes with economic and environmental-friendly logics have shown that many researchers are inclined to replace inefficient techniques with the new and efficient ones. Meanwhile, the machining industry, with its wide range of different processes, has accounted for a large share of industrial production. Cutting fluid (CF) is an inseparable part of machining processes, which their detailed study can have comprehensive feedback, including production costs, product quality, and human and environmental health. Knowing that over 65 % of lubricants disposals return to the environment with no purification process, and increasing regulations over pollution, therefore, suitable lubricant is demanded to replace with risky and low-efficiency one. The use of nanofluids is a practical solution to problems in today's industry that has been proposed by many researchers around the world. The present study has carefully studied the impact of various nanofluids in different sectors of the machining industry. The challenges of nanofluids such as biological effects, cost of nanoparticle production, and process limitations such as nanoparticles instability, changes in properties at high temperatures, increasing viscosity and pressure drop in transmission line are among the most important factors in the advancement of nanofluids, which were reviewed in the present work. Among them and as an important issue that many researchers haven't studied very well is the instability of the nanoparticles, which leads to nanoparticles adhesion to each other and weakening of the Brownian motion. Therefore, the stability of nanoparticles in the nanofluid is greatly reduced and they deposited rapidly, which fluid environment becomes empty of nanoparticles. Surface active agents (surfactant) can be a solution to this harmful phenomenon, which in the work, it has been tried to explain this issue in detail.
最近对经济和环境友好型制造工艺的研究表明,许多研究人员倾向于用新的和高效的技术来取代低效的技术。与此同时,机械加工行业因其广泛的不同工艺,在工业生产中占有很大的份额。切削液(CF)是机械加工过程中不可分割的一部分,对其进行详细的研究可以得到全面的反馈,包括生产成本、产品质量以及人类和环境健康。由于超过65%的润滑油处理后没有经过净化处理就会返回环境,而对污染的监管也越来越多,因此需要用有风险和低效率的润滑油来替代合适的润滑油。纳米流体的使用是当今工业问题的一种实际解决方案,已被世界各地的许多研究人员提出。本研究仔细研究了各种纳米流体对机械加工行业不同部门的影响。纳米流体面临的挑战,如生物效应、纳米颗粒生产成本、工艺限制,如纳米颗粒不稳定性、高温下性能变化、粘度增加和传输线压降等,是纳米流体发展的重要因素,本文对这些问题进行了综述。其中,纳米颗粒的不稳定性导致了纳米颗粒之间的相互粘附和布朗运动的减弱,这是许多研究人员没有很好地研究的一个重要问题。因此,纳米颗粒在纳米流体中的稳定性大大降低,并迅速沉积,使纳米颗粒在流体环境中变得空无一物。表面活性剂(表面活性剂)可以解决这一有害现象,在工作中,已试图详细解释这一问题。

Rice is cultivated on approximately 165 million hectares in over 100 countries, serving as a staple food for >3 billion people. Asia accounts for ∼90% of global rice production, while rice contributes around 40% of India's food grain production. Traditional rice cultivation relies heavily on water resources (between 1000 and 2000 mm), consumes high labour and energy, and emits substantial amounts of methane gases. As estimated, the annual mean atmospheric concentration of methane (CH4) ranged from 1889 to 2017 ppb (2020 annual mean across India), which is critical and demands an alternative, sustainable solution. Thus, the regenerative rice system stands out as a viable option to address these environmental challenges and can contribute to sustainable agricultural development while also reducing energy demands. This method employs direct seeding in non-puddled fields. It creates an aerobic soil environment, promoting strong rice roots and a median water reduction of 52.5% (IQR: 45–60%; n = 16 studies), thriving on 600–700 mm. Similarly, based on field experiments, an average decrease in energy consumption of 24.5% (IQR: 6.4–42.5%; n = 9 studies) and a 56% reduction in methane emissions (IQR: 34–78%; n = 9 studies) were observed. Regenerative rice contributes to Sustainable Development Goals 2 (Zero Hunger), 12 (Responsible Production and Consumption), 13 (Climate Action), and 15 (Life on Land), while reducing environmental impact compared to a puddled rice system. To evaluate its potential for scaling, this review examines existing research on regenerative rice production systems and proposes directions for future research, extension, and policy advocacy.
水稻种植面积约为1.65亿公顷,分布在100多个国家,是30亿人的主食。亚洲占全球大米产量的90%左右,而大米占印度粮食产量的40%左右。传统的水稻种植严重依赖水资源(1000到2000毫米),消耗大量的劳动力和能源,并排放大量的甲烷气体。据估计,大气中甲烷(CH4)的年平均浓度在1889至2017 ppb(印度2020年的年平均浓度)之间,这是至关重要的,需要一种替代的、可持续的解决方案。因此,再生水稻系统作为解决这些环境挑战的可行选择脱颖而出,可以促进可持续农业发展,同时还可以减少能源需求。这种方法是在无水坑的田地里直接播种。它创造了一个好氧土壤环境,促进了水稻根系的强壮,平均减水量为52.5% (IQR: 45-60%; n = 16项研究),在600-700毫米的土壤上茁壮成长。同样,基于现场试验,能源消耗平均下降24.5% (IQR: 6.4-42.5%, n = 9项研究),甲烷排放量减少56% (IQR: 34-78%, n = 9项研究)。再生水稻有助于实现可持续发展目标2(零饥饿)、12(负责任的生产和消费)、13(气候行动)和15(陆地上的生命),同时与水坑水稻系统相比,还能减少对环境的影响。为了评估其规模化的潜力,本文回顾了现有的关于水稻再生生产系统的研究,并提出了未来研究、推广和政策倡导的方向。

Enhancing flexibility in integrated gasification combined cycle systems: the role of syngas storage technologies and operational strategies 提高综合气化联合循环系统的灵活性:合成气储存技术和操作策略的作用
IF 7.9 Q1 ENGINEERING, MULTIDISCIPLINARY Pub Date : 2026-01-17 DOI: 10.1016/j.rineng.2026.109164

Integrated gasification combined cycle (IGCC) systems have a significant role in advancing the transition toward cleaner energy production by enabling the efficient and environmentally responsible use of coal and other carbon-based feedstocks. IGCC systems not only reduce emissions and improve thermal efficiency but also offer integration potential with emerging low-carbon technologies. Integrated gasification combined cycle with syngas storage (IGCC-SS) offers greater operational flexibility, particularly during maintenance periods or sudden power outages, and enhances the ability of the plant to respond to variable energy demands. This review focuses on analyzing syngas storage technologies and their operational considerations to enhance the flexibility, reliability, and scalability of IGCC systems. The feasibility of syngas storage is highly influenced by the physicochemical properties of syngas, which depend on the gasification operating conditions and the type of feedstock. These factors affect syngas composition, energy density, and flammability limits, all of which are critical for safe and effective storage. The integration of syngas storage in IGCC systems provides enhanced operational flexibility, enabling the system to adapt to a broader range of duty cycles and variable energy demands. However, it also has trade-offs, including reduced overall efficiency and increased energy production costs. Therefore, the process design configuration and operational variables must be carefully developed to achieve the optimal balance between performance, reliability, and economic viability. Future research may focus on optimizing syngas storage parameters and the syngas distribution ratio to minimize efficiency losses and enhance the adaptability of IGCC-SS systems to dynamic power grid requirements.
综合气化联合循环(IGCC)系统通过实现煤炭和其他碳基原料的高效和环保使用,在推进向清洁能源生产过渡方面发挥着重要作用。IGCC系统不仅可以减少排放,提高热效率,而且还具有与新兴低碳技术集成的潜力。集成气化联合循环与合成气储存(IGCC-SS)提供了更大的操作灵活性,特别是在维护期间或突然停电期间,并增强了工厂应对可变能源需求的能力。本文重点分析了合成气存储技术及其操作考虑,以提高IGCC系统的灵活性、可靠性和可扩展性。合成气的物理化学性质对合成气储存的可行性有很大的影响,这取决于气化操作条件和原料类型。这些因素影响合成气的组成、能量密度和可燃性限制,所有这些都是安全有效储存的关键。在IGCC系统中集成合成气存储提供了增强的操作灵活性,使系统能够适应更大范围的占空比和可变的能源需求。然而,它也有权衡,包括降低整体效率和增加能源生产成本。因此,必须仔细开发工艺设计配置和操作变量,以实现性能、可靠性和经济可行性之间的最佳平衡。未来的研究将重点放在优化合成气存储参数和合成气分配比上,以最大限度地降低效率损失,增强IGCC-SS系统对动态电网需求的适应性。

IGCC systems not only reduce emissions and improve thermal efficiency but also offer integration potential with emerging low-carbon technologies. Integrated gasification combined cycle with syngas storage (IGCC-SS) offers greater operational flexibility, particularly during maintenance periods or sudden power outages, and enhances the ability of the plant to respond to variable energy demands. This review focuses on analyzing syngas storage technologies and their operational considerations to enhance the flexibility, reliability, and scalability of IGCC systems. The feasibility of syngas storage is highly influenced by the physicochemical properties of syngas, which depend on the gasification operating conditions and the type of feedstock. These factors affect syngas composition, energy density, and flammability limits, all of which are critical for safe and effective storage. The integration of syngas storage in IGCC systems provides enhanced operational flexibility, enabling the system to adapt to a broader range of duty cycles and variable energy demands. However, it also has trade-offs, including reduced overall efficiency and increased energy production costs. Therefore, the process design configuration and operational variables must be carefully developed to achieve the optimal balance between performance, reliability, and economic viability. Future research may focus on optimizing syngas storage parameters and the syngas distribution ratio to minimize efficiency losses and enhance the adaptability of IGCC-SS systems to dynamic power grid requirements.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"29 ","pages":"Article 109164"},"PeriodicalIF":7.9,"publicationDate":"2026-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146022618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agricultural waste is a major global concern, with the potential to be a value-added material given its composition. Due to the high lignocellulosic content in various types of agro-waste, there has been a drastic increase in demand for bioethanol production. In this review, the investigators comprehensively emphasized the role of various pretreatment techniques in increasing bioethanol production from lignocellulosic biomass (LCB), particularly rice straw (RS). Here, investigators reviewed lignin removal, hemicellulose solubilization, sugar release, and ethanol generation reported in previously published experimental studies. A comparative study of all the available pretreatment approaches for the rice straw was emphasized. Further, the most effective and sustainable pretreatment strategies were identified, and their implications were focused on for scalable bioethanol production. The integrated pretreatment strategies were found to be more effective, sustainable, and scalable for the production of second-generation bioethanol. These methods closely align with the United Nations Sustainable Development Goals (SDGs), particularly SDGs 7, 12, and 13, which promote the generation of renewable biofuels from agricultural residues.
农业废弃物是全球关注的一个主要问题,鉴于其成分,有可能成为一种增值材料。由于各种类型的农业废弃物中木质纤维素含量高,对生物乙醇生产的需求急剧增加。在这篇综述中,研究人员全面强调了各种预处理技术在提高木质纤维素生物质(LCB),特别是稻草(RS)生物乙醇产量中的作用。在这里,研究人员回顾了木质素去除、半纤维素增溶、糖释放和乙醇生成在先前发表的实验研究报告。对现有的稻秆预处理方法进行了比较研究。此外,确定了最有效和可持续的预处理策略,并将重点放在可扩展的生物乙醇生产上。综合预处理策略对第二代生物乙醇的生产更为有效、可持续和可扩展。这些方法与联合国可持续发展目标(sdg)密切相关,特别是可持续发展目标7、12和13,这些目标促进了从农业残留物中生产可再生生物燃料。

The increasing lethality of ballistic threats and the increasing demand for lightweight and portable protection have revealed the critical limitations of conventional armor materials, such as high material density, poor flexibility, and limited multi-hit capability. In response, nanotechnology has emerged as a promising pathway for enhancing ballistic performance without sacrificing mobility. This review critically assesses the recent progress in ballistic protection systems enhanced by nanomaterials, focusing on carbon nanotubes, graphene, boron nitride nanotubes, and nano-enabled shear-thickening fluids (STFs). The analysis reveals that ballistic performance improvements are primarily governed by nanoscale mechanisms such as crack deflection and bridging, enhanced interfacial load transfer, and strain-rate-dependent stiffening. Despite these demonstrated advantages, the review identifies major barriers to practical implementation, including inconsistent nanoparticle dispersion, limited scalability of fabrication techniques, uncertain long-term durability, and environmental and health concerns. Based on these findings, a research roadmap is proposed emphasizing hybrid material architectures, scalable manufacturing strategies, multiscale computational modeling, and sustainable material design. The review concludes that overcoming these challenges is essential for translating nanotechnology-enabled armor systems from laboratory concepts into reliable, field-ready ballistic protection.
随着弹道威胁杀伤力的增加和对轻量化、便携式防护需求的增加,传统装甲材料的密度大、柔韧性差、多命中能力有限等严重局限性暴露出来。因此,纳米技术已经成为在不牺牲机动性的情况下提高弹道性能的有希望的途径。这篇综述批判性地评估了纳米材料增强弹道防护系统的最新进展,重点是碳纳米管、石墨烯、氮化硼纳米管和纳米剪切增稠流体(stf)。分析表明,弹道性能的改善主要是由纳米级机制控制的,如裂纹挠曲和桥接,增强的界面载荷传递,以及应变率相关的硬化。尽管具有这些优势,但该综述指出了实际实施的主要障碍,包括纳米颗粒分散不一致、制造技术的可扩展性有限、长期耐久性不确定以及环境和健康问题。在此基础上,提出了以混合材料架构、可扩展制造策略、多尺度计算建模和可持续材料设计为重点的研究路线图。该综述得出结论,克服这些挑战对于将纳米技术支持的装甲系统从实验室概念转化为可靠的、可用于战场的弹道防护至关重要。

Flood susceptibility mapping is a vital tool for risk assessment and disaster mitigation. This study presents a Geographic Information System (GIS)–based approach that integrates two fuzzy Multi-Criteria Decision-Making (MCDM) methods, fuzzy Analytical Hierarchy Process (FAHP) and fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS), to delineate flood-prone zones in the Kr. Keureuto catchment, north Aceh. The key innovation is applying a generalized-mean ranking method to define context-sensitive ideal and negative‐ideal solutions, replacing the usual fixed fuzzy positive and negative ideal solutions (FPIS/FNIS), to produce more robust weights and rankings under data uncertainty. Eleven hydrological, topographic, and land surface factors were analyzed, including rainfall, flow accumulation, elevation, slope, drainage density, proximity to rivers, topographic wetness index, land use/land cover, vegetation index, curvature, and soil type. Rainfall (weight: 0.223), flow accumulation (0.140), proximity to rivers (0.115), TWI (0.112), and drainage density (0.094) were the most influential factors. The resulting flood-susceptibility map shows that about 38 % of the basin, mainly downstream, is at high to very high risk, while the remaining 62 % is at moderate to low risk. Validation with observed flood records produced an area-under-the-curve- receiver operating characteristic (AUC-ROC) value of 0.921, demonstrating excellent predictive performance. By clearly linking spatial analysis with a more flexible decision framework, this research provides a practical decision-support tool for planners, disaster-management agencies, and local authorities to identify priority zones for structural and non-structural mitigation, guide land-use planning, and strengthen early-warning and evacuation strategies.
洪水易感性绘图是风险评估和减灾的重要工具。本研究提出了一种基于地理信息系统(GIS)的方法,该方法集成了两种模糊多标准决策(MCDM)方法,即模糊层次分析法(FAHP)和模糊理想解决方案相似偏好排序法(FTOPSIS),以划定亚齐北部Kr. Keureuto流域的洪水易发区。关键的创新是应用广义平均排序方法来定义上下文敏感的理想和负理想解,取代通常的固定模糊正理想解和负理想解(FPIS/FNIS),从而在数据不确定性下产生更稳健的权重和排名。分析了11个水文、地形和地表因子,包括降雨量、流量积累、高程、坡度、排水密度、靠近河流、地形湿度指数、土地利用/土地覆盖、植被指数、曲率和土壤类型。降雨量(权重:0.223)、流量累积(0.140)、靠近河流(0.115)、TWI(0.112)和排水密度(0.094)是最主要的影响因素。由此得出的洪水易感性图显示,约38%的流域(主要是下游)处于高至极高风险,而其余62%处于中至低风险。经实测洪水记录验证,曲线下面积接收者工作特征(AUC-ROC)值为0.921,具有较好的预测效果。通过将空间分析与更灵活的决策框架清晰地联系起来,本研究为规划者、灾害管理机构和地方当局提供了一个实用的决策支持工具,以确定结构性和非结构性减灾的优先区域,指导土地利用规划,并加强预警和疏散策略。

The escalating generation of electronic waste (e-waste) has rendered conventional disposal methods such as landfilling and incineration increasingly inadequate due to their associated environmental hazards, energy demands, economic inefficiencies, and poor material recovery rates. These traditional practices fall short in addressing the dual imperatives of resource efficiency and sustainable development. As an alternative, pyrolysis has emerged as a promising strategy for managing electronic plastic waste, offering notable advantages in terms of resource recovery and environmental protection. This review provides a comprehensive examination of five advanced pyrolysis techniques: vacuum pyrolysis, catalytic pyrolysis, co-pyrolysis, microwave-assisted pyrolysis, and plasma pyrolysis. It delves into their underlying reaction mechanisms, current development trends, and the technical challenges faced in practical applications. By analyzing experimental results and real-world implementations, the strengths and limitations of each method are critically assessed. While pyrolysis presents a viable route for the valorization of electronic polymers, its commercial deployment is hindered by challenges such as material degradation, catalyst performance, and energy optimization. To bridge the gap between research and industrial application, future efforts must prioritize the development of robust catalytic systems, integration of hybrid technologies, intelligent process control, comprehensive life-cycle assessments, and pilot-scale validation. Advancing these fronts will be essential for transitioning pyrolysis from experimental setups to scalable, environmentally responsible industrial operations. Future opportunities include microwave-assisted thermal storage for energy efficiency, multi-stage catalytic systems for contaminant removal, and hybrid plasma–catalytic approaches to improve cracking. Integrating digital tools such as machine learning and digital twin modeling can enable real-time optimization, accelerate scale-up, and strengthen the role of pyrolysis in advancing circular economy goals.
随着电子垃圾的不断增加,填埋和焚烧等传统的处理方法因其相关的环境危害、能源需求、经济效率低下和材料回收率低而日益不足。这些传统做法在解决资源效率和可持续发展的双重迫切需要方面做得不够。作为一种替代方案,热解已成为一种有前途的管理电子塑料废物的策略,在资源回收和环境保护方面具有显着优势。本文综述了真空热解、催化热解、共热解、微波辅助热解和等离子体热解五种先进的热解技术。它深入研究了它们的潜在反应机制,当前的发展趋势,以及在实际应用中面临的技术挑战。通过分析实验结果和现实世界的实现,对每种方法的优点和局限性进行了批判性评估。虽然热解为电子聚合物的增值提供了一条可行的途径,但其商业应用受到材料降解、催化剂性能和能量优化等挑战的阻碍。为了弥合研究与工业应用之间的差距,未来的努力必须优先发展强大的催化系统、混合技术的集成、智能过程控制、全面的生命周期评估和中试规模验证。推进这些前沿技术对于将热解从实验装置转变为可扩展的、对环境负责的工业操作至关重要。未来的机会包括提高能源效率的微波辅助储热,去除污染物的多级催化系统,以及改善裂解的混合等离子体催化方法。整合机器学习和数字孪生模型等数字工具可以实现实时优化,加速规模扩大,并加强热解在推进循环经济目标方面的作用。
