Thermal design and transient analysis of nitrogen Brayton cycle coupled with sodium-cooled fast reactor

open access: yes, 2022
Sodium-cooled fast reactors (SFRs) are one of the most promising reactor types for near-term deployment among Generation IV nuclear systems. Although the steam Rankine cycle has been generally adopted as a power conversion system (PCS) of an SFR, the ...

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

open access: yesChirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

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.
