Participant A compass for the Van der Waals force Making the invisible visible: For the first time, researchers have constructed a compass for the Van der Waals force — one of the fundamental binding forces of matter. An elongated molecule serves as a compass needle, which rotates depending on the strength and direction of the Van der Waals forces. It keeps geckos on the wall, contributes to the density anomaly of the water and shapes almost all interactions between atoms and molecules: the Van der Waals force is almost omnipresent. Because unlike electromagnetic attraction, it also works between neutral, uncharged partners — a slight redistribution of electrons is enough. In addition, this force is very weak and only extends a few nanometers, but increases disproportionately with the size of the bound objects. Van der Waals force EssaysVan der Waals force Essays Video
Efficient optimization of van der Wa Efficient optimization of van der Waals parameters from bulk properties Due to the computational cost involved, when developing a force field for new compounds, one often avoids fitting van der Waals vdW terms, instead relying on a general force field based on the atom type. Here, we provide a novel approach to efficiently optimize vdW terms, based on both ab initio dimer energies and condensed phase properties. The approach avoids the Van der Waals force Essays challenges of searching the parameter space by using an extrapolation method to obtain a reliable difference quotient for the parameter derivatives based on the central difference. This method is applicable to polarizable and nonpolarizable force fields, although we focus on the parameterization of the AMBER force ver.

The scaling of the electrostatic potential ESP of the compounds is also studied. The algorithm is tested on 12 compounds, reducing the root mean squared error RMSE of the density from 0. This is done with only four iterations of molecular dynamic runs.
When developing a force field for a compound, aVn van der Waals vdW terms is often avoided because of the computational complexity involved. This article provides a novel approach for efficiently optimizing vdW terms, based on both ab initio dimer energies and condensed phase properties. The approach avoids the challenges link exhaustively searching the parameter space by using an extrapolation method to obtain derivatives.]
