Density functional calculations for liquid metal surfaces

Surfaces of complex intermetallic compounds: insights from density functional calculations.

CONSPECTUS: Complex intermetallic compounds are a class of ordered alloys consisting of quasicrystals and other ordered compounds with large unit cells; many of them are approximant phases to quasicrystals. Quasicrystals are the limiting case where the unit cell becomes infinitely large; approximants are series of periodic structures converging to the quasicrystal. While the unique properties o...

Density Functional Theory Calculations of Functionalized Carbon Nanotubes with Metformin as Vehicles for Drug Delivery

Drug delivery by nanomaterials is an active emergent research area and CNTs draws considerable potential application owing to its unique quasi one-dimensional structure and electronic properties. Single walled carbon nanotubes and carbon fullerenes can be used in drug delivery due to their mechanical and chemical stability. The past few years, increasing attention by several reputed groups has ...

A standard grid for density functional calculations

An efficient and reasonably accurate grid, designated SG-1, is proposed for use in density functional calculations. Defined for all atoms from H to Ar, SC&I is recommended as a standard grid, analogous to the various standard basis sets which are used in contemporary quantum chemistry. In calculations on systems of moderate size, the differences between SCI and very large grids are of the order...

Relativistic density functional calculations for Pt2.

First full-relativistic density functional calculations with the extension of the spin-polarization functional for the relativistic density functional theory in their collinear and noncollinear form are presented here for the molecular system Pt2. The agreement with experiment is very good.
