Porphyrin‐Geländer–Helical Conjugated Banister Type Porphyrin Dyads

Chemistry – A European Journal, EarlyView.
Porphyrin arrays go chiral–A porphyrin Geländer macrocycle represents the intriguing prototype architecture of helically chiral butadiyne‐linked porphyrin arrays. This study combines synthetic, spectroscopic, and computational methods to shed light on its structure, chiroptical properties, and tunability, highlighting its promise for advancing ...

Alkyl Bismuth Cations: Synthesis, Characterization, and Application as Z‐Type Ligands

Chemistry – A European Journal, EarlyView.
Rare examples of alkyl bismuth cations [BiR2(SbF6)] are presented, including cyclopropyl ligands and a bismacyclic structure. The bismuth‐centered Lewis acids act as Z‐type ligands toward the electron‐rich platinum atom in [Pt(PCy3)2], generating a set of metal‐only Lewis pairs. The structural and spectroscopic properties of these rare types of bismuth

Variable Temperature Studies of Two Calcium Uranates α‐Ca3UO6 and Ca2UO5

Chemistry – A European Journal, EarlyView.
The structures and thermal responses of the calcium uranates α‐Ca3UO6 and Ca2UO5 were investigated using in situ synchrotron x‐ray diffraction and neutron powder diffraction. Despite the very similar chemical compositions, the structural response of the two calcium uranates is shown to be complex and varied.

Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.

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

The Canadian Journal of Chemical Engineering, EarlyView.
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.
