Comprehensive Modeling of Acetone Clusters: QTAIM Analysis and QCE Study
Journal of Computational Chemistry, Volume 47, Issue 11, 30 April 2026.A multiscale DFT‐QTAIM‐QCE approach links acetone cluster interactions to liquid‐phase behavior. Macroscopic thermodynamic and IR properties emerge from a dynamic equilibrium of small clusters. ABSTRACT In molecular research, comprehending the microscopic source of the macroscopic characteristics of polar aprotic solvents continues to be a significant ...

International Journal for Numerical Methods in Engineering, Volume 127, Issue 7, 15 April 2026.ABSTRACT In time‐marching dynamical simulations, treatment of contact forces in deformable bodies represented by finite element meshes requires a compromise between simulation fidelity and computational costs. External forces directly evaluated at the mesh nodes offer better computational performance at the cost of modelling fidelity.
