NN-Dx: Chemically adaptive dispersion physics for density-functional theory

The paper introduces NN-Dx, a chemically adaptive dispersion correction that integrates equivariant machine learning into a D4-inspired analytical framework to dynamically adjust atomic properties and interaction terms, thereby significantly reducing errors across various density functionals while preserving physical asymptotic behavior and enabling stable molecular dynamics.

How precise control of entanglement network formation can produce lighter-weight polyethylene with higher tenacity

This study demonstrates that precisely controlling the deformation of the physical entanglement network in polyethylene, rather than simply maximizing draw ratios, enables the production of lighter-weight materials with higher tenacity by promoting uniform rubber-like deformation over unstable necking.
