A turn-on AIE dual-channel fluorescent probe for sensing Cr/ClO and application in cell imaging.

A Cr/ClO-enhanced fluorescent probe, DNS (5-(dimethylamino)-N'-(2-hydroxy-4,6-dimethoxybenzylidene)-naphthalene-1-sulfonyl hydrazide), with aggregation-induced emission (AIE) properties was synthesized using dansylhydrazide and 4,6-dimethoxysalicylaldehyde as starting materials. The probe rapidly and selectively detects Cr and ClO in a solvent system of HO/DMSO (2:8). Upon binding with Cr/ClO, the probe exhibits a significant fluorescence enhancement, with minimal interference from other ions.

Molecular dynamics simulation on the displacement behaviour of crude oil by CO/CH mixtures on a silica surface.

Produced gas re-injection is an effective and eco-friendly approach for enhancing oil recovery from shale oil reservoirs. However, the interactions between different gas phase components, and the oil phase and rocks are still unclear during the re-injection process. This study aims to investigate the potential of produced gas re-injection, particularly focusing on the effects of methane (CH) content in the produced gas on shale oil displacement.
