Overview

Computational study demonstrates accurate property prediction and candidate screening in hydrocarbons, suggesting a scalable framework for aerospace fuel discovery.

Key Points

To assess whether a pretrained three-dimensional molecular representation learning framework can reliably predict physicochemical properties and accelerate the discovery of high-energy-density hydrocarbon fuels using minimal training data.
Fine-tuned the Uni-Mol 3D molecular representation model on 316,069 hydrocarbons from the GDB-13 database labeled with six physicochemical properties calculated via the group contribution method.
Assessed data efficiency by training on 1% of the dataset and extended evaluations across broader hydrocarbon subsets from GDB-17.
Conducted high-throughput computational screening on the candidate hydrocarbon space to identify top energetic molecules.
Uni-Mol achieved a flash-point mean absolute error of 1.67 K when trained on only 1% of the GDB-13 hydrocarbon training set.
The model attained coefficients of determination (R²) ranging from 0.9672 to 0.9998 across six physicochemical properties in GDB-17 hydrocarbons.
High-throughput screening successfully pinpointed seven polycyclic hydrocarbon candidates characterized by superior energy density and thermal stability.
