Computational studies of carbon decorated boron nitride nanocones
Density functional theory ,(DFT) calculations have been performed to investigate the properties ofcarbon decorated (C-decorated) models of boron nitride (BN) nanocones. To this aim, the apex andtip of nanocone have been substituted by the carbon atoms to represent the C-decorated models. Theresults indicated that dipole moments and energy gaps could reveal the effects of C-decorations onthe pro...
متن کاملNested boron nitride and carbon-boron nitride nanocones
In this letter we extend previously established results for nested carbon nanocones to both nested boron nitride and carbon-boron nitride nanocones. Based purely on mechanical principles and classical mathematical modelling techniques, we determine the energetically favourable structures for nested boron nitride and carbon-boron nitride nanocones. While only three apex angles for boron nitride ...
متن کاملElectron states in boron nitride nanocones
We apply first-principles calculations to study the electronic structure of boron nitride nanocones with disclinations of different angles θ = nπ/3. Nanocones with odd values of n present antiphase boundaries that cause a reduction of the work function of the nanocones, relative to the bulk BN value, by as much as 2 eV. In contrast, nanocones with even values of n do not have such defects and p...

متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
