Descriptor-Based Pre-Training Improves Reaction Property Prediction

ChemRxiv (preprint) | 2026 AI/MLCheminformatics

Introduces CheMeleon-Rxn, a pre-trained foundation model for reaction property prediction. Pre-training a reaction graph neural network on ~2 million reactions via descriptor regression, then fine-tuning on small labeled datasets, gives best-or-tied-best performance on seven of eight low-data benchmarks spanning activation energies, enthalpies, yields, and rate coefficients.

Binding Modes and Water-Mediation of Polyelectrolyte Adsorption to a Neutral CaCO₃ Surface

Langmuir | 2025 SimulationChemistry

Atomistic simulation of how a common water-treatment polymer adsorbs onto calcite surfaces. Identifies two distinct binding geometries, one through direct contact and one bridged by water molecules, and maps how each depends on chain length and calcium concentration.

Adsorption Isotherm and Mechanism of Ca²⁺ Binding to Polyelectrolyte

Langmuir | 2024 SimulationChemistry

Computes calcium binding curves for poly(acrylic acid) using enhanced-sampling molecular dynamics. Identifies the dominant binding geometries and their free-energy barriers, explaining how charged polymers capture calcium in water treatment.

Swimming in Potential Flow

JFM Rapids | 2022 PhysicsSimulationFluid Dynamics

A deformable body self-propels in potential flow by changing shape in ways that alter its added mass. The high-Reynolds-number propulsion mechanism is structurally identical to swimming at low Reynolds number, with added mass replacing the viscous resistance tensor.

Geometry and Dynamics of Lipid Membranes: The Scriven-Love Number

Physical Review E | 2020 PhysicsTheory

Continuum theory of lipid membrane dynamics across planar, spherical, and cylindrical geometries. Introduces the Scriven-Love number, a dimensionless ratio of in-plane viscous stress to elastic bending force. This ratio is non-negligible across a broad range of biological membrane processes.
