Surface Active Agents

Surface Active Agents

Surfactants, named for their behavior at interfaces, positively adsorb at the interfaces of two phases, reducing interfacial tension. Their versatility as emulsifiers, detergents, and foaming agents stems from this ability. Surfactants, often termed amphiphiles, share the property of amphipathy, with molecules having both hydrophilic and hydrophobic portions. The hydrophilic part is called the head, and the hydrophobic part, including an elongated alkyl substituent, forms the tail.Surfactants...

Surface Tension of Fluid

Surface Tension of Fluid

Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension.
Surface tension varies with...

Area of Science:

Chemical Engineering
Materials Science
Artificial Intelligence

Background:

Predicting surfactant physical properties for enhanced oil recovery (EOR) is challenging.
Conventional machine learning and graph neural networks struggle with coupled molecular and environmental interactions.

Purpose of the Study:

To develop a novel Gated Message-passing Graph Neural Network with an Attention Mechanism (Gated-MPNN-AT).
To accurately predict interfacial tension (IFT) in surfactant-oil-water systems by integrating molecular structure and environmental features.

Main Methods:

Proposed a Gated-MPNN-AT model with a dual gated mechanism for message passing.
Employed a Cross-Attention mechanism for in-depth interaction between molecular topology and environmental parameters.
Designed a hybrid robust loss function for handling diverse IFT data distributions.

Main Results:

The Gated-MPNN-AT model demonstrated superior prediction accuracy compared to Random Forest, XGBoost, GCN, and GAT.
Ablation studies showed the gated mechanism improved R-squared by 4.8% and Cross-Attention reduced MAE by 21.3%.
The model exhibits good generalization and robustness against abnormal IFT data.

Conclusions:

The Gated-MPNN-AT model effectively predicts interfacial tension for enhanced oil recovery applications.
The proposed model overcomes limitations of existing methods by integrating molecular and environmental data.
This approach offers a promising tool for optimizing surfactant performance in EOR.
