(2010)Protected areas are the most important tool for the conservation of biodiversity. However. many species are area-demanding and their populations seldom meet their space requirements in reserves. In this context, the ...
-
(Wiley-VCH Verlag, 2014)Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, is a major health problem worldwide. In this work, we report the development of palladium and platinum metal complexes with 5-nitrofuryl-containing ...
-
(Elsevier, 2016)Graphene materials often are obtained through thermal reduction of graphite oxide. This is due to the fact that other synthesis methods are more difficult and generally render lower yield. The structure and morphology of ...
-
(Hindawi Publishing, 2015)The effect of the nanoscale structure of bioceramics on their in vitro bioactivity and capacity to osteogenically differentiate stem cell is studied. Nanoparticles of hydroxyapatite (nHA), bioactive glass (nBG), nanoporous ...
-
(1989)The critical micelle concentration, cmc, the dissociation degree, α, and the transfer free energy of anions Δμt° from water to micelle for different cetyltrimethylammonium salts CTAS (S = benzenesulfonate, OBSP-; tosylates, ...
-
(Royal Society of Chemistry, 2018)The reaction of 2,4-dinitrobenzenesulfonyl chloride toward propylamine was kinetically evaluated in 19 organic solvents and 10 ionic liquids as reaction media. This study was compared with a previous study to experimentally ...
-
(SOC CHILENA QUIMICA, 2010-03-16)In this study, we compared four glassy carbon electrodes modified with adsorbed porphyrins of cobalt containing one, two, three, or four bis(methoxyphenyl) groups as substituents of the ligand. The aim of this work was ...
-
(AMER CHEMICAL SOC, 2006-04-10)Three structures of novel cluster carboxylates of molybdenum(II) (la-c) and copper(II) (2) with the OOC-CCHCo2(CO)(6) ligand are presented. The solvent topology plays an important role in the formation of the crystal lattice ...
-
(MDPI, 2021)The removal of necrotic and vital pulp substrates and microorganisms and their toxins from the root canal system (RCS) has been found to be the basis for a successful endodontic treatment. In this study, our aim was to ...
-
(John Wiley & Sons, 2013)Raman and surface enhanced Raman scattering (SERS) spectroscopies were used to study the pH effect (7 to 9) on the interaction of arginine (Arg) with colloidal Ag nanoparticles (AgNps). A new methodology was implemented ...
-
(2013)The effect of preparation method, either coimpregnation or sequential impregnation, and of calcination temperature (between 500 degrees C and 700 degrees C) of CuO-CeO2/SiO2 catalysts on the CuO-CeO2 interface and on their ...

(SOCIEDAD CHILENA DE QUIMICA, 2002-09)Kraft bleached cellulose from Pinus radiata was submitted to methylation reactions in heterogeneous media. After activation with 29% (w/w) NaOH solution, methylation reactions were carried out both with dimethyl sulfate ...
-
(Universidad de Chile, 2020-12)There are a lot of studies about the effect of behavioral elements on financial issues. On the theoretical front one of the most important contributions is Prospect Theory (Kahneman and Tversky, 1979), where the authors ...

(2009)Periodic density functional theory calculations on large supercells have been carried out to investigate the atomic and electronic structure of small gold particles (Au2, Au4, Au9, Au13, and Au14) supported on the (001) ...
-
(International Society for Horticultural Science, 2018)Mexico provides 95% of the export market blackberry (Rubus fruticosus) worldwide. The characteristic black color of this fruit is an important quality factor. During its postharvest management, it can reverse its color ...
-
(Royal Soc., 2015)We describe the collective behaviour of a system of many inelastic spherical particles inside a box which is being periodically vibrated. The box is shallow, with large horizontal dimensions, while the height is less than ...
-
(Elsevier, 2015)Active volcanoes fromHokkaido are distributed along the SW–NE trending volcanic front,where the subducting Pacific plate changes direction fromN–S toWSW–ESE. One exception is the Tokachi volcano,which is located ...
-
(Elsevier, 2015)Welfare of working horses is a matter of public concern, with scarce information on their possible physiological coping mechanisms. The aim of this study was to assess changes in possible physiological welfare indicators ...
