Molecular dynamics study of the threshold displacement energy in vanadium
نویسنده
چکیده
The threshold displacement energy ~TDE! is calculated for vanadium as a function of temperature and orientation by molecular dynamics simulations. The TDE varies from 13 to 51 eV, depending on orientation and is nearly temperature independent between 100 and 900 K. The lowest TDE is in the ^100& direction. We characterize the defects associated with the displacement simulations and found that they consist of vacancies and ^111&-split dumbbells.

Potassium Channels allow potassium flux and are essential for the generation of electric current acrossexcitable membranes. Potassium Channels are also the targets of various intracellular controlmechanisms; such that the suboptimal regulation of channel function might be related to pathologicalconditions. Realistic studies of ion current in biologic channels present a major challenge for compu...

There are questions concerning the functions of artemin, an abundant stress protein found in Artemiaduring embryo development. It has been reported that artemin binds RNA at high temperatures in vitro, suggesting an RNA protective role. In this study, we investigated the possibility of the presence of RNA-bindingsites and their structural properties in artemin, using docking energy ...
متن کاملThreshold displacement energy and damage function in graphite from molecular dynamics
The environment dependent interatomic potential (EDIP) including ZieglereBiersackeLittermark (ZBL) interactions for close encounters is applied to cascades starting from a host atom and from an interstitial atom. We find the room temperature displacement threshold to be 25 eV, increasing to 30 eV at 900 K. The latter correlates well with the measured threshold for vacancy production. Additional...
