This study aims to comprehensively characterize and optimize microwave-induced pure carbon dioxide plasma focusing on the enhancement of conversion and energy efficiency. Analysis of optical emission spectra and gas composition under varying flow rates, introduced microwave power, and operating pressures was performed, while specific calculations were applied to support the measurement including electron concentration, electron temperature, and plasma gas temperature. A characteristic curve of carbon dioxide plasma is introduced as a novel outcome, which helps to elucidate the positive impact of applying reduced pressure. 46.4% carbon dioxide conversion efficiency was demonstrated by applying 5 NL·h⁻¹ flow rate, 80 mbar, and with 14.5 MJ·mol⁻¹ molar energy input utilizing only neat carbon dioxide, and achieved with continuous operation, without using any catalyst, in a straight waveguide system. The results indicate that lowering the pressure enhances the specific power absorption of plasma from the electromagnetic field through electron collisions, which increases the carbon dioxide conversion instead of converting it into heat.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11705-025-2563-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145162875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The third-generation biomanufacturing concept leverages microbial cell factories to convert renewable energy sources, including solar and electrical energy, and inorganic materials, into high-value fuels and chemicals. Microbial CO₂ fixation, with its mild reaction conditions and ability to generate diverse products, is a compelling alternative to traditional chemical catalysis, which is generally characterized by high energy demands, pollution, and limited product diversity. <i>Clostridium</i> stands out among microorganisms for its natural ability to fix carbon via the Wood-Ljungdahl pathway, which enables CO₂, CO, and H₂ to be used for growth and product synthesis. Advances in genetic engineering tools for <i>Clostridium</i> have led to the biosynthesis of over 40 natural compounds, expanding its industrial potential. Furthermore, integrating <i>Clostridium</i> into photoelectrochemical systems has demonstrated the feasibility of coupling microbial fermentation with renewable energy inputs. This review comprehensively examines the Wood-Ljungdahl pathway, related metabolic pathways, and key enzymes, along with the latest progress in genetic modification tools. The potential of <i>Clostridium</i> as a biocatalyst for one-carbon gas conversion and its integration with clean energy technologies is highlighted, offering valuable perspectives for future research.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 10","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145145368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Along with numerical and analytical modeling, these variables are described by various two- and three-dimensional models, which have also developed for these parameters and variables. For engineering the selective layer, different categories of materials based on various morphologies, dimensions, or porosity were used as interlayers. Regarding the interlayers, there are relatively inconsistent reports in the literature and publications, primarily due to a lack of research and modeling. By modeling the influence of interlayers in thin film composite membranes, an innovative insight could be provided for optimizing other membrane processes. As a result, this research emphasizes the modeling and discussion of interlayers and their performance, particularly in the forward osmosis process, where scientific data and modeling are lacking. In addition to discussing the funnel and gutter effect carried out by the interlayers present in all membrane processes, modeling the impacts of the interlayer in the forward osmosis process will provide novel perspectives that could influence other processes.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AI techniques are being widely employed in the chemical industry and are constantly evolving to offer more effective solutions for tackling practical challenges. This review delves the transformation of the chemical industry from traditional digital simulations to advanced AI-based approaches, targeting high efficiency and low carbon emissions across the scale from molecules to factories. Particular emphasis is mainly placed on the research carried out within the research group of Weifeng Shen. At the molecular level, the intelligent capture of molecular characteristics and the precise determination of structure-property relationships have reached a mature stage. Furthermore, multifunction-driven reverse molecular design for solvents, reaction reagents, and other substances has been accomplished through AI-based high-throughput screening and generative models. To improve the safety, environmental friendliness, and carbon reduction performance of chemical separation processes, a series of innovative reinforcement strategies have been put forward, with a primary focus on the systematic optimization of solvent design. On the process scale of actual production, it frequently occurs that the constructed mechanism model fails to align with the actual system behavior, thereby restricting the industrial application of the model. To solve this issue, mechanism-data hybrid-driven frameworks have been successfully developed, leveraging AI-enhanced prediction, diagnosis, optimization, and control for complex separation systems in practice. Finally, as a bridge connecting big data intelligent technology and actual industrial processes, dynamic digital twin modeling is discussed for its potential to boost efficiency and sustainability in the chemical industry.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 7","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145168823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is currently no term to describe the use of artificial intelligence for regenerative engineering. Therefore, we hereby present a new term, “Regenerative Engineering AI”, which cohesively describes the interweaving of artificial intelligence into the framework of regenerative engineering rather than using it merely as a tool. As the first to define the term, regenerative engineering AI is the interdisciplinary integration of artificial intelligence and machine learning within the fundamental core of regenerative engineering to advance its principles and goals. It represents the subsequent synergetic relationship between the two that allow for multiplex solutions toward human limb regeneration in a manner different from individual fields and artificial intelligence alone.

However, high-dimensional industrial data often exhibit complex structures, making the traditional 2D visualization methods ineffective at distinguishing different fault types. Thus, a visual process monitoring method that combines supervised uniform manifold approximation and projection with a label assignment strategy is proposed herein. First, the proposed supervised projection method enhances the visualization step by incorporating label information to guide the nonlinear dimensionality reduction process, improving the degrees of class separation and intraclass compactness. Then, to address the lack of label information for online samples, a label assignment strategy is designed. This strategy integrates kernel Fisher discriminant analysis and Bayesian inference, assigning different label types to online samples based on their confidence levels. Finally, upon integrating the label assignment strategy with the proposed supervised projection method, the assigned labels enhance the separability of online projections and enable the visualization of unknown data to some extent. The proposed method is validated on the Tennessee Eastman process and a real continuous catalytic reforming process, demonstrating superior visual fault monitoring and diagnosis performance to that of the state-of-the-art methods, especially in real industrial applications.\u0000</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":571,"journal":{"name":"Frontiers of Chemical Science and Engineering","volume":"19 7","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144131491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
