THE DENSITY PROFILES OF A LENNARD -JONES FLUID CONFINED TO A SLIT
The structure of fluids confined by planar walls is studied using density functional theory. The density functional used is a generalized form of the hypernetted chain (HNC) functional which contains a term third order in the density. This term is chosen to ensure that the modified density functional gives the correct bulk pressure. The proposed density functional applied to a Lennard-Jones...
متن کاملApplying Density Functional Theory to Study NLO Properties of Benzyne-Based Chromophores
Density Functional Theory (DFT) calculations were employed to investigate the structural characteristics, electronic properties, and nonlinear optical properties of Benzyne-Based Chromophores at B3LYP/6-31G(d,p) level. The effects on the hyperpolarizabilities of various donor and acceptor substituent (H, F, Cl, Br, Me, NH2, OH, NH3+, COOH, CHO, CN, NO,NO2 ) were studied. The results reveale...
متن کاملYoung’s Modulus and Poisson’s Ratio of Monolayer Graphyne
Despite its numerous potential applications, two-dimensional monolayer graphyne, a novel form of carbon allotropes with sp and sp2 carbon atoms, has received little attention so far, perhaps as a result of its unknown properties. Especially, determination of the exact values of its elastic properties can pave the way for future studies on this nanostructure. Hence, this article descr...
متن کاملDensity and Polarization Profiles of Dipolar Hard Ellipsoids Confined between Hard Walls: A Density Functional Theory Approach
The density and polarization profiles of the dipolar hard ellipsoids confined between hard walls are studied using the density functional theory (DFT). The Hyper-Netted Chain (HNC) approximation is used to write excess grand potential of the system with respect to the bulk value. The number density is expanded up to zero and first order in polarization to find the results. For the zero order in...
متن کاملDensity Functional Theory Studies of Defects in the (5,5) Silicon Nanotube
We have performed density functional theory (DFT) calculations to investigate the properties of defect in arepresentative armchair model of silicon nanotubes (SiNTs). To this aim, the structures of pristine and defective(5,5) SiNTs have been optimized and the properties such as bond lengths, total energies, binding energies,.formation energies, gap energies, and dipole moments have been evaluat...
