Each month, Chemical Engineering highlights several novel technologies from academia and industry in the Chementator section. From water treatment to artificial intelligence to carbon capture (and much more), the Chementator section truly covers the gamut of groundbreaking chemical engineering work. Please find below the ten most-read Chementator articles of 2025.
Please also look over the 2025 CE Year in Review for our technical feature to see the topics that most resonated with readers last year.
