Highlights with ‘ReaxFF’

Oriented Attachment of TiO2 Nanocrystals

The growth of TiO2 nano-particles has been studied with reactive molecular dynamics (ReaxFF) by researchers from Penn State. While in vacuum the particles aggregate in the orientation of approach, in aqueous phase the nanocrystals have...

Water adsorption and dissociation on titania surfaces with ReaxFF

Researchers from Penn State studied the adsorption and dissociation of water on various anatase surfaces and rutile (110) at various coverages with a newly developed reactive force field. The reactive MD calculations agree with previous...

Char combustion modeled with ReaxFF

Modeling the detailed chemical reaction dynamics of a complex system at the atomistic level is computationally too demanding for quantum-chemical methods and impossible with traditional force fields based on equilibrium properties. In the ReaxFF force...
