(2003)It has been shown that innocent ligands always contribute with a similar electron density to a metal centre in a complex regardless of which other innocent ligands are bonded to the same centre, while non-innocent ligands ...
-
(Sociedad Chilena de Quimica, 2017)The development of new biomaterials has gained increasing attention in the last decade. One of the most important aspects in the development of these new materials is to understand the chemical cues presents in the native ...
-
(1991)Infrared data for N-benzylideneanilines mono- and disubstituted predict, in agreement with CNDO molecular orbital calculations, that the internal energy transfer is induced mainly by a donor group in para position of the ...
-
(Universidad de Chile, 2011)
-
(Royal Society of Chemistry, 2020)Because of their photothermal properties, gold nanoparticles (AuNPs) have gained attention regarding their use in drug delivery and therapeutic applications. In this sense, it is interesting to consider their interactions ...
-
(2017)Los colorantes naturales, extraídos de hojas y raíces de plantas como el extracto de Henna, han sido utilizados desde la antigüedad para otorgar color a todo tipo de indumentarias textiles. El desarrollo de colorantes ...
-
(Elsevier, 2000)Recent literature results on inorganic models related to metalloenzymes which transport electrons or activate small molecules are discussed in this review. The molecular systems are essentially restricted to macrocyclic ...
-
(2007)Polycyclic Aromatic Hydrocarbons (PAHs) were detected at trace concentrations. In order to accomplish that, new SERS substrates were developed based on silver nanoparticles, both in suspension and immobilized in glass. ...
-
(MDPI AG, 2018)Photoluminescent mechanisms in erbium-doped barium titanate nanoparticle systems were studied. Er3+ ions were introduced into the BaTiO3 lattice by the sol-gel method. The resulting Er3+ concentration was between 0% and ...
-
(Universisdad de Chile, 2011)Este trabajo de tesis esta enfocado al estudio vibracional mediante espectroscopia amplificada por superficie metálica (SERS) de la secuencia MRKDV modelo de péptido amino terminal de hemocianinas de moluscos. La hemocianina ...
-
(Springer, 2017)We report the first absolute dating for rock paintings by Andean hunter-gatherer groups. Analysis by Raman spectrometry of remains of black paintings from the center-north of Chile (30° lat. S) allows for the identification ...
-
(Taylor and Francis Inc., 2016)© 2016, Copyright © Taylor & Francis Group, LLC. The natural dyes lawsone and plumbagin (1,4-naphthoquinones) were studied by using fluorescence, Raman, infrared (IR), surface-enhanced Raman scattering (SERS), and ...
-
(2009)Hemocyanin, the oxygen transporter metallo-glycoprotein from mollusks, shows strong relationship between its notable structural features and intrinsic immunomodulatory effects. Here we investigated the individual contribution ...
-
(2007)The interaction between adsorbates of different nature and plasmonic nanoparticles is reviewed here on the basis of the work done in our laboratory in the past few years. The paper is structured for analyzing the interaction ...
-
(1986)By means of an iterative consistency method it has been determined a complete potential field for the urea molecule. The force constants set which interpretates well the vibrational spectra of urea and its deutero derivatives ...
-
(2012)The role of the titanium dioxide (rutile and anatase) with and without room light on the thermal synthesis of the glycine-l-glutamine (Gly-Gln) polymer is described. The efficiency in percentage of polymerization with room ...
-
(1998)The infrared spectra of naphthalocyanine (H2Nc) and its copper(II) complex (CuNc) were registered in the region 4000-450 cm-1. These compounds were deposited onto a smooth copper surface and their specular infrared spectra ...
-
(Marcel Dekker. Inc., 1987-04-11)Thymine dimers were obtained under ultraviolet irradiation. The major product is a trans-anti dimer linked by a cyclobutane ring. The infrared assignments and the mechanism of formation of this dimer are discussed in ...
-
(Elsevier, 1996)FT-IR spectra of the title compounds and derivatives were measured in the range 4000-120 cm-1. A complete experimental spectral assignment has been performed. A simplified normal coordinate treatment orientates some ...
-
(Universisdad de Chile, 2015)Este trabajo de tesis se centra en estudiar la interacción entre bioanalitos de diferentes complejidad molecular con nanoparticulas de plata coloidal (AgNps) obtenidas por reduccion del ion Ag+ mediante clorhidrato de ...
