Highlights with ‘materials science’

Visualization of local temperatures and other atomic properties with ADFmovie

Local temperature averaging in ReaxFF ReaxFF (development version r63428) can now calculate atomic temperatures and spatial averages thereof. Atomic temperatures are saved to the trajectories per default whilst the averaging is activated by the presence...

EU Nanotech mission Japan: 14-16 February

See ADF in Action at Nanotech 2018 in Tokyo’s Big Sight! Fedor joins the EU Nanotech/SME cluster mission at the International Nanotechnology Exhibition & Conference. Come and discuss your research challenges and find out how...

Tutorial: Battery Discharge Voltages with Grand Canonical Monte Carlo / ReaxFF

A brand new advanced ReaxFF tutorial is now available: Learn how you can combine grand canonical monte carlo simulations with ReaxFF and, with just a little bit of PLAMS, calculate discharge voltage profiles. The discussed systems and...

Korea workshop: Chemistry & Materials modeling (Daejeon, 9 February)

Bring your laptop to Daejeon to learn hands on how to tackle your chemistry & materials science problems with computational chemistry! After the workshop you will can explore the ADF Modeling Suite further for one...

Tutorial: Li-Ion diffusion coefficients with ReaxFF

We have set up an advanced tutorial in which we discuss how to calculate Li-Ion diffusion coefficients with ReaxFF in (dense) materials both directly from a trajectory and by means of extrapolation from high temperatures....

Benchmark: density functionals and settings for band gaps

Jetsabel Figueroa, MSc. student in the OptoElectronics group at the TU Delft, benchmarked band gap calculations with BAND. During her internship with SCM she made use of the python scripting tool PLAMS (see the script with...

Controlled doping of organic semiconductors

The process of electrical doping, or charge transfer in general terms, was used in the early stages of developing organic electronics when conducting polymers were first discovered. Since then it has been largely unexplored in stark contrast...

Hydrogen embrittlement of steels: a ReaxFF study

Hydrogen embrittlement substantially decreases the mechanical strength of metallic systems, such as carbon steels, often leading to catastrophic failures in these materials. This is a particular problem for materials exposed to hydrogen, in particular the...

Characterizing aqueous cysteine in bulk and at the surface

Reactive molecular dynamics simulations (ReaxFF) and X-ray photoelectron spectroscopy were used to investigate both the bulk and the surface distribution of cysteine species in aqueous solution. Experimentally, the protonation state of cysteine, which in water...

Cysteine nanodroplet on a titania surface

Molecular Dynamic simulations based on a reactive force field (ReaxFF) have been shown to be the most appropriate method to characterize the adsorption of droplets of cysteine molecules on TiO2 rutile (110) slabs producing results...
