In the current study, synthesis and characterization of a new nano-structured zirconium(IV)-minoxidil complex (1), where minoxidil, (C9H15N5O; 6-(1-Piperidinyl)-2,4-pyrimidinediamine 3-oxide), have been investigated in two different solvents. The compound 1 has been synthesized by sonochemical method in the presence of methanol and monoethylene glycol (MEG) as solvents and characterized by scan...

In this study the interaction of cis-PtCl2(NH3)2 complex and graphene were investigated with MPW1PW91method in gas and solvent phases. The solvent effect was examined by the self-consistent reaction fieldtheory (SCRF) based on Polarizable Continuum Model (PCM). The selected solvents were chloroform,chlorobenzene, bromoethane, dimethyldisulfide, and dichloroethane. The solvent ...

In this research we report synthesis of new Barium- Cobalt precursor complex with 2,6- pyridine dicarboxylic acid (dipic).Thecomplex[Ba(H2O)6][Co(dipic)2[(1)has been characterized using spectral methods (FT-IR, UV–Vis),elemental analysis and Cyclic voltammetric (CV) method. Also in this study we report thermal decomposition of inorganic precursor complex of (1).Characterization of the binary ox...

the work  addressed in this paper is a comparative study between convergence of the  acceleration techniques, diagonal pad'{e} approximants and shanks transforms, on homotopy analysis method  and adomian decomposition method for solving  differential equations of integer and fractional orders.

in this paper, the multistage variational iteration method is implemented to solve a general form of the system of first-order differential equations. the convergence of the proposed method is given. to illustrate the proposed method, it is applied to a model for hiv infection of cd4+ t cells and the numerical results are compared with those of a recently proposed method.

in this paper, plate-like nio nanoparticles were prepared by one-pot solid-state thermal decomposition of nickel (ii) schiff base complex as new precursor. first, the nickel (ii) schiff base precursor was prepared by solid-state grinding using nickel (ii) nitrate hexahydrate, ni(no3)2∙6h2o, and the schiff base ligand n,n′-bis-(salicylidene) benzene-1,4-diamine) for 30 min without using any solv...

in this paper, we present a comparative study between the adomian decomposition method and two classical well-known runge-kutta and central difference methods for the solution of damped forced oscillator problem. we show that the adomian decomposition method for this problem gives more accurate approximations relative to other numerical methods and is easier to apply.

the sst decomposition method for solving system of linear equations make it possible to obtain the values of roots of the system with the specified accuracy as the limit of the sequence of some vectors. in this topic we are going to consider vectors as fuzzy vectors. we have considered a numerical example and tried to find out solution vector x in fuzzified form using method of sst decomposition.

Generalized intervals (intervals whose bounds are not constrained to be increasingly ordered) extend classical intervals providing better algebraic properties. In particular, the generalized interval arithmetic is a group for addition and for multiplication of zero free intervals. These properties allow one constructing a LU decomposition of a generalized interval matrix A: the two computed gen...
