Performance comparison of pressure swing adsorption and amine‐based absorption for synthesis gas purification

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 5012-5027, September 2026.
Comparison of PSA and amine‐based absorption for syngas purification shows that PSA offers lower energy intensity, global warming potential, and minimum selling price, making it a more sustainable option. However, absorption achieves higher syngas purity. A GREENSCOPE‐based multi‐criteria assessment guides optimal process selection.

Gradient‐Based Optimization Modeling of Total Entropy and Heat Transfer in Exothermic Blood Analog Gold Nanoparticle Suspension

Engineering Reports, Volume 8, Issue 9, September 2026.
This study develops a gradient‐based multi‐start Nelder–Mead optimization framework for Casson‐micropolar blood‐analog nanofluid flow with gold nanoparticles in a convectively heated, exothermic microchannel, motivated by photothermal drug delivery. Spectral collocation solves coupled momentum, microrotation, and energy equations, from which entropy ...
