The title compound, [Zn3(C2H5)2(C6H5O3)4]·2C7H8, crystallizes with one complex mol-ecule solvated by two mol-ecules of toluene in the asymmetric unit. The Zn(II) ions are coordinated by two terminal ethyl (Et) groups and four maltolate ligands, which act as μ3- and μ2-bridges. The metal atoms are arranged in an incomp…

In quasi-one-dimensional organic crystals, the relaxation time as a function of carrier energy can exhibit, under certain conditions, a rather high and sharp maximum. It is shown that this maximum and its position on the energy scale influence the electrical conductivity and electronic thermal conductivity in differen…
A new ligand N , N -bis-(2-benzimidazolylmethyl)L-methionine has been synthesized and well characterized by different analytical techniques. The ligand has a very strong affinity for silver(I) and is used for the selective extraction of silver ions from aqueous solution into 1-butanol. The effect of concentration of A…
This paper outlines the design, modeling and testing of a new class of tool intended for the treatment of crack-arrest holes to improve fatigue life. By integrating a stack of high-power piezoelectric elements in a compression caliper, this Piezoelectric Impact Compressive Kinetic (PICK) tool can be used to clamp very…
Abstract In this work, we present the synthesis of cationic surfactants based on 1‐aminoisoindole. The physico‐chemical properties were studied by conductometry, tensiometry, dynamic light scattering and transmission electron microscopy in water and in formamide. The reactivity of these novel surfactants has been stud…
An electrically conductive polyaniline (PANi) membrane has been coated on the end of an optical fiber to form a fiber optoelectrode for simultaneously monitoring electrical and optical responses of the polymer membrane exposed to gas samples. Two electrodes were glued on the side of the optical fiber for measuring the…
In this Comment, we point out that the Euler-Lagrange equations, which are referred to as the general equilibrium equations by Zhao et al. [Phys. Rev. E 74, 032801 (2006)] are incorrect along with the equations which are derived from them. The correct equations are provided in this Comment. We produce new numerical re…
O cultivo das plantas de cobertura pode proporcionar melhorias e reestruturacao de atributos quimicos e fisicos do solo, reduzir a resistencia do solo a penetracao e aumentar a permeabilidade do solo a agua reduzindo, assim, a erosao hidrica, razao pela qual se objetivou com este trabalho, avaliar o potencial de espec…
Experimental band gap energies of 208 semiconducting single-wall carbon nanotubes (n, m) from 0.4 nm to 3 nm are analyzed by dividing them in mod (n-m, 3) =1 and 2 types. Eects of nanotube curvature and chirality (n, m) on their band gap energies are closely investigated. An exponential empirical relation of band gap…
In industry, membrane separation of gas mixtures is of considerable significance. For example, the composite poly (4-methyl-2-pentyne) (PMP) and silica nanoparticle is used to separate C 4 H 10 ( n -butane) from mixtures of C 4 H 10 and CH 4, H 2, etc. Silica has different crystalline forms. The transport properties o…

By the use of the reduced Rayleigh equation for the amplitude of a surface plasmon polariton on a one-dimensional randomly rough metal surface that is in contact with vacuum, we calculate the dispersion and damping of the surface electromagnetic wave to the lowest nonzero order in the rms height of the surface. It is…
Abstract Two heterospin complexes [Cu(NIT3Py)(cda)H2O]·H2O (1) and [Cu(NIT2Py)(cda)H2O]·H2O·CH3OH (2) with CuII ions and pyridyl‐substituted nitronyl nitroxide radicals (NITxPy = 2‐(x′‐pyridyl)‐4,4,5,5‐tetramethyl‐imidazoline‐1‐oxyl‐3‐oxide, x = 3, 2; H2cda = 4‐hydroxy‐pyridine‐2,6‐dicarboxylic acid) were synthesized…
In the present study, we propose a method to fabricate large-area graphene-based thin films using rapid low temperature reduction of graphene-oxide. Large area (~17.5 sq.cm.) graphene oxide (GO) thin films are fabricated by vacuum filtration of GO solution synthesized by the modified Hummers' method. The graphene-oxid…
Abstract The production of hydrocarbons with minimum drawdown pressure requires removal of the filter cake formed during overbalanced drilling. In such an operation, the delayed-breaker system used consists of an acid precursor that reacts slowly with water in the carrier brine and releases a strong organic acid, whic…
The confinement of liquid crystals in a small space induces interesting phenomena that deviate from the bulk properties. We report on the electro-optical properties of ferroelectric liquid crystals (FLCs) confined in transparent photonic crystal fibers (PCFs). A PCF has a large number of cylindrical air holes of micro…
Ferromagnetic Mn3Ge2 thin films were successfully grown on GaAs(001) and GaSb(001) substrates using molecular beam epitaxy. The results of our work revealed that the substrate facilitates to modify magnetic and electrical properties of Mn3Ge2 films due to tensile/compressive strain effect between films and substrates.…
The direct transformation of nanoclusters into nanorings has recently been observed during the annealing of Au clusters on an indium-tin-oxide layer [F. Ruffino et al., Appl. Phys. Lett. 98, 023101 (2011)]. The energetic origins of this process are investigated in the context of an analytical model for general heteroe…
