Zn Substitution in Na4Fe3(PO4)2(P2O7) Cathodes: Limits of Redox‐Inactive Doping Revealed by XAS and RIXS

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
This study demonstrates that dopant selection critically influences phase purity and electrochemical performance in Na4Fe3(PO4)2(P2O7) (NFPP) cathodes. While Zn2+ does not enhance conductivity, inappropriate doping increases impurity formation during synthesis.

Technoeconomic and sustainability analysis of batch and continuous crystallization for pharmaceutical manufacturing

open access: yesAIChE Journal, Volume 72, Issue 7, July 2026.
Abstract In pharmaceutical industries, continuous manufacturing methods have already been well established to improve productivity and process intensification. However, to better understand the trade‐offs of continuous crystallizers over the existing batch production systems, a robust technoeconomic cost and sustainability analysis is necessary to ...

Annular flow enhanced two-phase evaporative heat exchanger for space-based systems [PDF]

open access: yes, 1991
The development of multi-kilowatt space-based systems requires the transport of waste heat loads over long distances in micro-gravity conditions. In this context two-phase heat transport systems are attractive enabling a high rate of heat transport ...

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3692-3713, July 2026.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3775-3795, July 2026.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...
