Dirubidium hexaaquacobalt(II) tetrakis(hydrogen phthalate) tetrahydrate and coordination modes of the hydrogen phthalate anion
(Int Union Crystallography, Chester, 2013)
The title compound, Rb-2[Co(H2O)(6)](C8H5O4)(4)center dot 4H(2)O, consists of nearly regular octahedral [Co(H2O)(6)](2+) cations with the Co-II cations on the inversion centre (special position 2a), Rb+ cations, hydrogen ...
Carboxylic acids and polyethylene glycol assisted synthesis of nanocrystalline nickel ferrites
(Elsevier Sci Ltd, Oxford, 2013)
Different synthesis methods for the preparation of nanocrystalline nickel ferrites are reported: the thermal decomposition of precursors, made of: (i) metal-nitrate salts with carboxylic acids (citric, malonic and tartaric), ...
Thermodynamic and Spectroscopic Study of the Ternary System Dimethyladipate plus Tetrahydrofuran+1-Butanol at T = (288.15 to 323.15) K
(Amer Chemical Soc, Washington, 2013)
Experimental densities rho, refractive indices and viscosity eta data of the ternary dimethyladipate + tetrahydrofuran + 1-butanol and the binary tetrahydrofuran + 1-butanol systems have been determined, while viscosities ...
A Study of Applicability of Nonlinear Frequency Response Method for Investigation of Gas Adsorption Based on Numerical Experiments
(Amer Chemical Soc, Washington, 2013)
A study of the applicability of the Nonlinear Frequency Response (NFR) approach for investigation of equilibrium and kinetics of gas adsorption, based on numerical simulations, is presented. Pressure responses of a batch ...
Particle velocities in quasi two-dimensional water fluidized beds of spherical particles
(Elsevier, Amsterdam, 2013)
Particle velocities have been measured in two-dimensional water fluidized beds of mono-sized spherical glass particles d(p) = 1.94, 2.98, 4.00 and 6.00 mm in diameter. For each particle size, a separate column was constructed ...
Flexible Transistors Exploiting P3HT on Paper Substrate and Graphene Oxide Film as Gate Dielectric: Proof of Concept
(Amer Scientific Publishers, Valencia, 2013)
In this paper we report: the use of graphene oxide in aqueous solution as a gate dielectric material, its application to a MOS transistor based on organic semiconductor and the use of paper as substrate material.
Positron lifetimes in pores of some low-silica zeolites: influence of water content, crystal size and structural type
(Springer, Dordrecht, 2013)
Positron annihilation lifetime spectroscopy has been used for observation of the free voids in low silica zeolites, of LTA and FAU structure and different crystal size, before and after their heating at different temperatures ...
Experimental measurement and modelling of viscosity of the binary systems pyridine or nicotine with polyethylene glycols at T = (288.15-333.15) K. New UNIFAC-VISCO and ASOG-VISCO interaction parameters
(Elsevier Science Bv, Amsterdam, 2013)
Viscosities of four binary mixtures: pyridine + PEG200, pyridine + PEG400, nicotine + PEG200 and nicotine + PEG400 have been measured in temperature range 288.15-333.15 K with temperature step of 5 K and at the atmospheric ...
Adsorption of chromium (VI) from aqueous solutions onto amine-functionalized natural and acid-activated sepiolites
(Elsevier Science Bv, Amsterdam, 2013)
Chromium(VI) adsorption onto amine-functionalized sepiolites from aqueous solution at 298 K was investigated. Natural and add-activated sepiolites were functionalized by covalent grafting [3-(2-aminoethylamino)propyl] ...
Coexistence of several sillenite-like phases in pseudo-binary and pseudo-ternary systems based on Bi2O3
(Elsevier, Amsterdam, 2013)
A series of polycrystalline samples containing sillenite-like (doped gamma-Bi2O3) phases were prepared by high-temperature reactions from alpha-Bi2O3 powder and different oxides in six pseudo-binary Bi2O3-MxOy (M = Mn, Ti, ...
