The title mononuclear Ni(II) complex, [Ni(C(11)H(11)N(2)O(5))(2)(C(2)H(8)N(2))(2)], is built up by inversion symmetry associated with the central Ni atom. The ethyl-enediamine ligands are non-planar. The r.m.s. deviation from the mean plane of the five-membered Ni-ethyl-amine chelate ring plane is 0.1945 Å. In the cry…
The hydrogenases are metalloenzymes that act to catalytically interconvert dihydrogen with protons and electrons. Although there are three classes of hydrogenases that are known, the focus of this research will be on the first hydrogenase to be evolved, the [NiFe]-hydrogenase, which contains a heterobimetallic NiFe ac…

Transport properties of exfoliated graphene samples on SiO2 are examined from four-probe electrical measurements combined with electrical and thermal modeling. Data are analyzed with practical models including gated carriers, thermal generation, ???puddle??? charge, and Joule heating. Graphene mobility is characterize…
The title one-dimensional coordination network, {[Gd(2)(NO(3))(6)(C(10)H(8)N(2)O(2))(3)]·2CH(2)Cl(2)}(n), is isostructural with the previously reported Tb and Tl coordination networks and to its Eu analog. The Gd(III) cation is coordinated in a distorted tricapped trigonal-prismatic fashion by nine O atoms from three…
In this work, a liquid crystalline octopolar molecule 1,3,5-tris(ethynylphenyl)benzene-(1) was successfully embedded as dopant chromophore within a SiO2 based sonogel network in order to prepare stable solid state hybrid materials with intense second harmonic generation (SHG). This recently synthesized octopolar compo…
Let G be a simple graph of order n and let S be any subset of the vertex set V(G). We denote by G S, T the graph obtained from G by adding two new non-adjacent vertices x, y, so that x is adjacent exactly to the vertices from S, and y is adjacent exactly to the vertices from T, where T=V(G)∖S. We here determine the co…

$TiO_2$ thin films were synthesized on carbon fibers using chemical vapor deposition. We show that these films can exhibit extraordinarily high absorption capacities of toluene vapor. Such an absorption phenomenon of toluene at room temperature was not found for other $TiO_2$ samples. Upon toluene absorption change in…
This paper describes the preparation and study of thermally stimulated discharge conductivity (TSDC) study of cellulose triacetate (CTA) - multiwalled carbon nanotubes (MWNTs) film thermoelectrets. TSDC has been carried out in the temperature range 308 - 503 K and at four different polarizing fields. The conductivity…
The origin and methodology of deriving effective model hierarchies are presented with applications to solidification of crystalline solids. In particular, it is discussed how the form of the equations of motion and the effective parameters on larger scales can be obtained from the more microscopic models. It will be s…
Theoretical studies have been performed to study the binding characteristics of the alkali metal iodides, M-I (M = Li, Na, K), to poly(ethylene oxide) (PEO, I), poly(ethylene amine) (PEA, II) and poly(ethylene N-methylamine) (PEMA, III) via the B3LYP method. In this study, two types of complexes, singly-coordinated sy…
The vast majority of propellant ignition data has been collected and studied for heat fluxes in the typical, intentional ignition range. However, when a propellant contained within a rocket motor case is exposed to low fluxes in hazardous situations, such as close proximity to a fire, unwanted ignition can also occur.…
Human body type classifications are very crucial issue, play an even important role for physiology, medical treatment, sports talent and garment production and logistics. The extraction of knowledge from large database has been successfully applied in a number of advanced fields by data mining. However, little researc…

We study a tunable-focus lens with convex and flat electrodes in a homogeneous liquid crystal (LC) cell. In a voltage-on state, a centro-symmetric gradient refractive index is generated within the LC layer, which causes the focusing behavior for the extraordinary wave. There have been experimental studies of the syste…
Abstract Dizinc(II) complexes of two acyclic Schiff‐base ligands L1– and L2– were synthesized by Schiff base condensation of 2‐[3‐(2‐formylphenoxy)‐2‐hydroxypropoxy]benzaldehyde (PL) with 1,2‐diaminopropane and 1,2‐diaminoethane, respectively, in the presence of zinc(II) salts. The isolation of a selection of 2:1 (met…
Molecular theory of Brownian motion of a single heavy particle in a fluid had received a considerable attention in earlier years.[1][2][3][4][5][6][7] After molecular dynamics (MD) simulation technique was utilized, this subject has been widely studied by a variety of MD simulation methods.[8][9][10][11][12][13][14][1…
Palygorskite is a dominant clay mineral in most soils and sediments in central Iran. Few studies investigated the formation of palygorskite under the influence of groundwater in central Iran. This study aims to identify the effects of groundwater on the formation of palygorskite and associated clay minerals. Four soil…
