(2010)Dimethoate, diazinon, parathion methyl, pirimiphos methyl, malathion, fenthion, chlorpyriphos, methidathion and azinphos methyl were determined in 71 olive oil samples produced in Chile from different varieties of olives ...
-
(2000)Experiments and three-dimensional numerical simulations are presented to elucidate the dynamics of granular material in a cylindrical dish driven by a horizontal, periodic motion. The following phenomena are obtained both ...
-
(2014)Inorganic fillers such as CaCO3 and clays are widely used as fillers to improve the mechanical and physical properties of polypropylene (PP). With the aim of improving simultaneously the stiffness and yield stress of PP, ...

(2003)Surface tension measurements have been made in aqueous solutions of anionic hemiesters of an alternating copolymer of maleic acid and styrene, MAS-n with n=0-12, in the presence of dodecyltrimethylammonium bromide, DTAB. ...
-
(2014)The molecular structure of the exo-3,6-dimethyl-3,6-epoxi-1,2,3,6-tetrahydrophthalimide (1), determined by X-ray diffraction analysis, as well as, its complete spectroscopic characterization and the synthesis and complete ...
-
(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 ...
-
(Elsevier, 2018-05)The antioxidant capacity of hydroxylated coumarins and hydroxybenzoic acids has been widely described. However, there is little information on the antioxidant activity when both systems are functionalized. In this work, ...
-
(Wiley-VCH Verlag, 2018)© 2018 Deutsche Pharmazeutische Gesellschaft With the purpose of expanding the structural variety of chemical compounds available as pharmacological tools for the treatment of Alzheimer's disease, we synthesized and evaluated ...

Synthesis and Biological Screening of Novel Indolalkyl Arenes Targeting the Serotonine Transporter (Wiley, 2014)A series of functionalized indolylalkylarenes 3–16(a and b) were synthesized and their affinities for the serotonin transporter were investigated in vitro. Compounds 3–12(a and b) were obtained by nucleophilic substitution ...
-
(Taylor & Francis, 2016)The synthesis and phase characterisation of two homologous series of monomers of acrylic azo-compounds has been presented. The characterisation comprises polarising optical microscopy (POM), differential scanning calorimetry ...
-
(Hüthig & Wepf Verlag, 1998)The synthesis of a novel kind of form-retaining liquid crystalline crosslinked metallopolymer is reported. Copper(II) is complexed by Schiff's base units as part of a mesogenic side chain polymer. This leads to remarkable ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2002-12)A new Rhenium (I) and Ruthenium(II) bimetallic polipyridilcarbonil complex and the corresponding monometallic precursor complexes were prepared. The compounds were characterized physically and spectroscopically (Elemental ...
-
(JOHN WILEY & SONS, 2008-08)Novel ruthenium (II) complexes were prepared containing 2-phenyl-1,8-naphthyridine derivatives. The coordination modes of these ligands were modified by addition of coordinating solvents such as water into the ethanolic ...
-
(Taylor & Francis Ltd., 1997)The syntheses and structural properties of four liquid crystalline monomers are presented. They are prepared by two different reaction pathways. Transition temperatures and phase characterization were done by DSC, ...
-
(TAYLOR & FRANCIS LTD, 1993)We present the synthesis and a description of the physical properties of several organic dyes containing stilbene as well as azomethine groups. The preparations of all compounds started from a common precursor, ...
