Introducing a mathematical workflow for scaling‐up the cyclic solvent injection process: Experimental studies and dimensional analysis utilizing Buckingham pi theorem

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Cyclic solvent injection (CSI) is an effective enhanced oil recovery (EOR) technique with several economic and environmental benefits. However, the successful implementation of CSI at commercial scales requires reliable scaling criteria. In this study, CSI has been formulated comprehensively by integrating material balance, mass transfer, and ...

Exploring the Photophysical Processes of an Al3+ Sensor Based on Schiff Base

open access: yesChemPhysChem, EarlyView.
Multiple excited‐state intramolecular proton transfer (ESIPT) processes and twisted intramolecular charge transfer (TICT) states are observed on the S1 state potential energy surface of an Al3+ sensor. The ESIPT process induces an ultrafast CC rotation process and leads to a non‐emissive TICT state.

Donor–Acceptor Interactions of C60F18 with Polycyclic Aromatic Hydrocarbons: Size Effects in Bulk Crystallization and Surface Constraints

open access: yesChemPlusChem, EarlyView.
Donor–acceptor (D/A) interactions between spheroidal C60F18 and three planar polycyclic aromatic hydrocarbons (PAHs)—coronene (CORO), perylene , and pyrene—show a strong dependence on PAH size. X‐Ray diffraction reveals increasing layered stacking (either D/A/D/A or D/A/A/D/A/A).

Intensification of Ethylene Carbonate Synthesis via Microwave‐Induced Phase‐Change Cycles

open access: yesChemSusChem, EarlyView.
Microwave‐assisted heating under ambient pressure reflux conditions is applied to intensify the transesterification of ethylene glycol with dimethyl carbonate. The proposed method enhances energy efficiency and product yield compared to conventional heating, enabling lower catalyst loading, reduced process time, and significantly decreased energy ...
