Here, we show that there are many cases where the chemical bonding and van der Waals (vdW) interactions both play a key role in chemical reactions on surfaces. After briefly introducing some DFT methods and basic theory in chemical reactions, we first demonstrate that DFT can help to ...

It has long been surmised, as a theoretical curiosity, that conditions could arise under which the sign of the van der Waals interaction between two different uncharged bodies, surrounded by a liquid, might be negative, i.e. that such bodies would repel each other. This possibility is ...

Van der Waals forces are among the weakest, yet most decisive interactions governing condensation and aggregation processes and the phase behaviour of atomic and molecular matter. Understanding the resulting structural motifs and patterns has become increasingly important in studies of the nanoscale regime...
However, they found that in the case of van der Waals two-body interactions the binding energies at unitarity are approximately given solely in terms of the van der Waals length. It has not been reported how the relationship between EN+1/EN−1 and EN/EN−1 changes when moving away ...
II.A.1.d van der Waals energy The van der Waals term, EvdW, covers nonelectrostatic interactions between nonbonded atoms. The van der Waals energy is positive (repulsive) and very large at short distances, zero at large distances, but slightly negative (attractive) at moderate distances due...
