Numerous materials have been proposed as alternatives to polyamide for RO in recent decades. However, in spite of numerous publications on these new materials, it is remarkable to see how <em>none</em> has even come close to succeeding in replacing conventional RO membrane materials in a commercial setting. This is largely because many of these new materials are incompatible with existing membrane manufacturing approaches such as interfacial polymerization. We must be able to process new materials into thin, defect-free films on conventional supports. This is a significant hurdle for new material adoption in membranes today.

These properties allow them to interact with the contaminants at the molecular level, making them suitable for MNP detection.

Additionally, plastic debris serves as a source of allochthonous carbon to marine ecosystems — a factor that has only drawn scientific attention recently. Herein, we synthesize recent evidence about this new form of plastic carbon in the ocean by addressing it as three components: particulate organic carbon of plastic (<em>pPOC</em>), dissolved organic carbon leaching from plastic (<em>pDOC</em>), and biogenic organic carbon of plastic-attached biofilm (<em>pBOC</em>). Current estimates of <em>pPOC</em> and <em>pDOC</em> account for only a modest fraction of natural carbon pool in the ocean, but their portions are expected to increase. <em>pDOC</em> is highly heterogenous, varying by polymer types, and has been shown to influence seawater biogeochemistry as well as the structure and function of microbial communities. Furthermore, biofilm biomass colonizing on plastic debris can utilize the <em>pP</em>OC and <em>pDOC</em> as carbon sources. Current evidences proved the incorporation of plastic carbon into microbial biomass, which consequently affects the carbon and nitrogen cycling. Given these emerging insights, we further suggest specific research questions aimed at stimulating research on the nature, dynamics, and role of plastic carbon in the ocean.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101101"},"PeriodicalIF":8.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The convergence of major innovations from the computer science field has the potential to revolutionize the engineering and control of complex industrial systems. Digital twinning and process simulation have been a staple of computers in process engineering for decades now. However, the advent of advanced sensor systems and big data integration, combined with generative AI and agentified AI (classic and quantum) systems, allows for much more granular and autonomous process control and real-time optimization of complex systems. Advanced process modeling, Agentic AI, and generative AI models have emerged as powerful tools to address the challenges of complex nonlinear systems. We propose here an integrated systems feedback and control architecture (SIC: Sense, Infer, Control) that leverages complementary process knowledge for enhanced real-time monitoring and decision-making, fully integrated into control system functions and the accompanying sensors. In this paper, we explore this integration of generative models in agentic AI ensembles into industrial processes through the lens of four recent industrial case studies: (1) the real-time optimization of motorsports strategy, (2) the development of indirect (soft) sensors for sustainable large-scale manufacturing operations, (3) the creation of sensor data-driven personalized health and cosmetic chemical formulations, and (4) the design of biomanufacturing systems using quantum and classic Agentic AI. These examples demonstrate how agentic and generative models, combined with full-scale process simulation and digital twinning, effectively augment process control, enabling advanced solutions for process optimization, quality improvement, and sustainable operations. The proposed SIC systems architecture serves to enhance process control automation by capturing complex nonlinear patterns and leveraging easily measurable variables. Generative models bridge gaps in process understanding, sensor technologies, control, and monitoring, offering actionable insights for efficient and informed decision-making across diverse industrial applications.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101150"},"PeriodicalIF":8.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
