CJCE’s latest virtual issue is now live: Exploring Themes: Top-Viewed Articles from Across Chemical Engineering. This virtual issue features top-viewed articles published in 2024–2025 from each of its thematic areas

Within this virtual issue, you will find articles exploring a variety of topics from across the chemical engineering field. For example, in an open access review article by Pradeep Sambyal, Parisa Najmi, Devansh Sharma, Ehsan Khoshbakhti, Hadi Hosseini, Abbas S. Milani, and Mohammad Arjmand titled “Plastic recycling: Challenges and opportunities”, the authors provide “an in-depth exploration of current strategies for recycling plastic waste, focusing on mechanical, chemical, and energy recovery methods.” The article “situates these strategies within the context of modern practices by examining ongoing research methodologies and specific case studies related to various types of plastic waste” and discusses “the global crisis of plastic waste, along with various pre-treatment methods”. The authors note that the review “aims to provide a thorough overview and practical guidance on the recycling of plastic waste, offering essential insights for further development in this area.”

In “Artificial intelligence and machine learning at various stages and scales of process systems engineering”, authors Karthik Srinivasan, Anjana Puliyanda, Devavrat Thosar, Abhijit Bhakte, Kuldeep Singh, Prince Addo, Rajagopalan Srinivasan, and Vinay Prasad “review the utility and application of artificial intelligence (AI) and machine learning (ML) at various process scales in this work, from molecules and reactions to materials to processes, plants, and supply chains” and “highlight whether the application is at the design or operational stage of the process” with a focus on “the distinct representational frameworks employed at the various scales and the physics (equivariance, additivity, injectivity, connectivity, hierarchy, and heterogeneity) they capture.”

In a review article titled “Microfluidic devices, materials, and recent progress for petroleum applications: A review” by Stefanía Betancur, Lina Quevedo, and Carol M. Olmos, the authors “provide a comprehensive overview of microfluidic devices, their materials, and their applications in the petroleum industry.” In addition, “Throughout the paper, the advantages and disadvantages of implementing microfluidic devices and utilizing specific materials are thoroughly discussed. This analysis provides valuable insights into the challenges and potential limitations associated with this technology.”
