[ 1 ] - High Efficient Transparent TiO2 Nanotube Dye-Sensitized Solar Cells: Adhesion of TiO2 Nanotube Membrane to FTO by Two Different Methods
In order to fabricate transparent TiO2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from Ti substrate by a re-anodization method. The membranes are transferred on FTO glass by two different methods. At the first one, 100mM Ti-isopropoxide is used to make TiO2 nanoparticles for adhering TiO2 nanotube membranes to FTO and ...
[ 2 ] - Investigation on the ordering of titanium oxide nanotubes fabricated by anodization on different substrate surface morphologies
In this study, titanium oxide nanotubes anodized on threedifferent surface morphologies of titanium foils, were investigated. AFM imagesis used to show different surface roughness of these foils. Nanotubes wereanodized on titanium foils with 1) no polishing process (A sample), 2)electropolishing process (B sample) and 3) electropolishing process in ethanolicelectrolyte (C sample). To study the ...
[ 3 ] - Density 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...
[ 4 ] - Solvation Force of Ellipse-Shaped Molecules Moving in One Dimension and Confined between Two Parallel Planar Walls
The model fluids containing hard ellipses (HEs) and Gay-Berne (GB) particles where their center is moving in one dimension and confined between two parallel walls with different interactions are investigated using Monte Carlo simulation, NVT ensemble. The dependency of fluid pressure with respect to the wall distances is studied. The oscillatory behaviors are seen in this quantity against ...
[ 5 ] - First Principle Study of MC (M= Al, Ga, and In) at Equilibrium and under Negative Stress
The electronic and magnetic properties of the hypothetical compounds of MC (M=Al, Ga and In) are investigated by using first-principle calculations and pseudopotential plane wave self-consistent field method based on density functional theory. In order to find the most stable phase of MC (M=Al, Ga and In), we study them in zinc-blende (ZB), rocksalt (RS), wurtzite and NiAs crystal structures. W...
[ 6 ] - بررسی گذار فاز مایع - جامد با استفاده از نظریه تابعی چگالی وزنی اصلاح شده مایعات کلاسیک غیر یکنواخت با مولکولهای کروی سخت
In this article we first introduce the weighted density approximation (WDA) to study the classical inhomogeneous system such as inhomogeneous fluids. Then we introduce the modified weighted density approximation (MWDA) to calculate the structure and thermodynamical properties of the FCC hard sphere crystal. The MWDA is a self consistent method where the free energy is expressed as an unperturb...
[ 7 ] - بررسی ساختاری و ترمودینامیکی مایعات مولکولی مخلوط دوتایی مولکولهای بیضویگون با برهمکنش گی- برن
In this paper, a uniform classical fluid mixture comprising ellipsoidal molecules is studied. This mixture is composed of two types of ellipsoidal molecules interacting through the Gay-Berne potential with different sizes at temperature T. For this system, the Ornstein-Zernike equation using the Percus-Yevick closure relation is solved. Then the direct correlation function, pair correlation fu...
