Interfacial Regulation for Enhanced Gas/Oil Recovery and CO2 Geo-sequestration from Molecular Perspectives
DownloadFall 2021
The interfaces between two immiscible fluids or between fluid and solid are ubiquitous. The interfacial properties between aquifers and hydrocarbons have significant effects on the distribution and production of gas and oil, whereas understanding the fluid-solid interfacial phenomena is important...

Investigation of the Molecular Mechanism of the Environmental Stress Cracking of Polyethylene by Molecular Simulation
DownloadFall 2024
In this molecular dynamics (MD) simulation study, we investigated the impact of an environmental stress cracking (ESC) agent, nonyl ethoxylate (NE), on the packing and free volume coalescence in between polyethylene chains and the ESC agent, focusing on linear polyethylene (LPE) and branched...

Spring 2021
Asphaltenes are the heaviest and most polar group of molecules in crude oil. Colloidal behaviors of asphaltenes, including the aggregation and interfacial behaviors, have impacts on many petroleum production processes. For example, the aggregation of asphaltenes can lead to problems such as...
