Electric controlling of surface metal-insulator transition in the doped BaTiO3 film

AIP Advances, 2017
Based on first-principles calculations, the BaTiO3(BTO) film with local La-doping is studied. For a selected concentration and position of doping, the surface metal-insulator transition occurs under the applied electric field, and the domain appears near

A new integrated numerical wave tank in OpenFOAM for hydrodynamic modelling of offshore renewables

Applied Ocean Research
This paper presents a new integrated hydrodynamic modelling framework for wave–structure interaction problems. It is developed by coupling a finite-volume-based fully nonlinear potential flow (FNPF) solver with the native OpenFOAM incompressible ...

Expander Graphs and their Applications

, 2006
A major consideration we had in writing this survey was to make it accessible to mathematicians as well as to computer scientists, since expander graphs, the protagonists of our story, come up in numerous and often surprising contexts in both fields. But,

The electronic structures and optical properties of B, C or N doped BaTiO3

AIP Advances, 2018
The electronic structures and optical properties of Boron, Carbon or Nitrogen doped BaTiO3 are calculated by the first-principles calculations. The doped atoms decrease the band gap of BaTiO3 significantly, which could increase the host material ability ...

Finite Difference Simulation on Biomagnetic Fluid Flow and Heat Transfer with Gold Nanoparticles towards a Shrinking Sheet in the Presence of a Magnetic Dipole

Computer Sciences & Mathematics Forum, 2023
In this paper, we study the laminar, incompressible, and steady flow of a biomagnetic fluid, such as blood, containing gold nanoparticles through a shrinking sheet in the presence of a magnetic dipole. This model is consistent with both the principles of
