Daniele Marchisio discusses the importance of chemical reaction rates with respect to physical transport rates with the help of the Damköhler numbers.

Translating chemical processes from laboratory to industrial scales is a critical aspect of chemical engineering. At the journal, we view scale-up as a complex path whose significance depends not only on the demonstrated scale, but also the underlying science.

Kristala Prather from the Massachusetts Institute of Technology talks to Nature Chemical Engineering about her path into metabolic engineering, the influence of her industrial experience and how the existing gap with academia is more an opportunity rather than a problem.

Identifying and estimating operative timescales can help win over a skeptical referee, as Tom Dursch recounts.

Modeling chemical processes and systems underpins progress in chemical engineering science; we encourage submissions in this domain.

Jennifer Curtis from the University of California Davis talks to Nature Chemical Engineering about her path into particle technology, work in computational simulations of multiphase particle flows and the importance of industrial collaborations in advancing the field.

Wastes can be leveraged for decarbonization, provided we know how to think about them, argues Corinne D. Scown.

Crystallization plays a pivotal role in the manufacturing of pharmaceuticals. This Comment briefly reflects on past achievements and emerging opportunities in industrial crystallization, particularly considering increasing molecular and system complexities.

Electrification endows modern separation processes with the capability to tackle a broader array of challenges using potentially sustainable energy resources.

An appreciation of characteristic timescales can save quite a lot of effort, as Ian Wilson explains.

Junwang Tang and Binhang Yan discuss the role of the Industrial Catalysis Center at Tsinghua University and their perspectives on modern industrial catalysis with Nature Chemical Engineering.

The existential threat posed by the climate crisis calls for urgent solutions to manage hard-to-abate and unavoidable CO₂ emissions. This Comment shows, by example, the key role that scientists can play in launching pioneering pilot projects, leveraging their research, systems understanding and networks, and thus educating the next generation of climate innovators.

Katarina Babić reflects on the need to account for variability in plastic waste feedstocks when designing plastic upcycling and recycling processes.
