Counterion and composition effects on discotic nematic lyotropic liquid crystals - I. Size and order
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2007-12-01)
Counterion and composition effects on the size and interface dynamics of discotic nematic lyotropic liquid crystals made of tetradecyltrimethylammonium halide (TTAX)-decanol (DeOH)-water-NaX, with X = Cl- and Br-, were ...
Estudio de síntesis de sales de fosfonio derivadas del ácido gálico
(Universidad de Chile, 2012)
Se sintetizaron sales de fosfonio derivadas del ácido gálico con potencial actividad biológica, por medio de dos estrategias sintéticas. La primera ruta está compuesta de 3 pasos, donde la esterificación se realizó a través ...
Syntheses, properties, crystal and molecular structure of a novel neutral pentanuclear copper(I) iodide species. Copper(I) complexes with tetraethylthiuram monosulfide
(1998)
The reaction of copper(I) iodide with tetraethylthiuram monosulfide LEt afforded the novel copper(I) pentanuclear neutral complex [CU5LEt2I5]·EtOH·MeCN 1. Its crystal structure may be described as a very distorted octahedral ...
How Meaningful Is the Halogen Bonding in 1-Ethyl-3-methyl Imidazolium-Based Ionic Liquids for CO2 Capture?
(American Chemical Society, 2018)
© 2018 American Chemical Society. We report on several parameters that can be used to describe the 1-ethyl-3-methyl-4,5-(X2)imidazolium cations (where X = H, Br, and I) within the Canongia-Lopez and Padua Force Field (CL&P) ...
Protonated bis(quinuclidine) included in a novel "bichannel" (urea)-chloride host: a very large urea channel
(TAYLOR & FRANCIS LTD, 2004-03)
The synthesis, crystal structure and properties of a novel ternary inclusion compound formed by protonated bis(quinuclidine) inserted in a urea-chloride anionic host, urea(5)[quinuclidine(2)H]Cl-+(-) (1), are reported. In ...
Titanocene modulation of cytokine imbalance induced by Ehrlich ascites tumour progression
(Elsevier B.V., 2004-10-25)
In the present work, we have studied the effects of two titanocenes, biscyclopentadienyldichlorotitanium IV (DDCT) and its derivative, biscyclopentadienylditiocianatetitanium IV (BCDT), on the production of cytokines ...
The sulfoxidation reaction catalyzed by CoBr2 complexes, under the magnifying glass of green parameters
(Elsevier B.V., 2018-07)
Different cobalt (II) and nickel (II) species were used as catalysts in sulfoxidation reactions giving excellent yields and high chemoselectivity. Among the cobalt (II) species, both γ-cyclodextrin complexes synthesized ...
Is σ-hole an electronic exchange channel in YX⋯CO interactions?
(Elsevier Science, 2018)
A theoretical study of linear YX⋯CO complexes (in which YX are diatomic interhalogens or hydrogen halide) has
been performed to high-level quantum chemical calculations. Calculations show that at the equilibrium geometry,
the ...
Effect of Additives on the Cloud Point of the Octylphenol Ethoxylate (30EO) Nonionic Surfactant
(Brasil, 2013)
The effect of different additives on the cloud point (CP) of an octylphenol ethoxylate (OPEO30) aqueous solution was investigated. The CP of OPEO30 is higher
than 100 C due to its approximately 30 oxyethylene units per ...
Síntese e análise estrutural de clusters derivados de Hg(EPh)2 (E = Se, Te)
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2009-03-04)
This work presents a study related to the synthesis and structural analysis of clusters derivative from Hg(EPh)2 (E = Se, Te). Bis(phenylchalcogenide)mercury was used as starting material, which is considered a building ...
