Electrificación del uso de calor residencial proyecciones en Chile y su rol en la gestión de demanda (Universidad de Chile, 2021)El uso de la leña residencial es una de las principales fuentes de contaminación atmosférica en la zona centro-sur de Chile, por ello el gobierno ha implementado una serie de políticas públicas para desincentivar su consumo. ...
-
(Universidad de Chile, 2008)El objetivo principal de este trabajo fue maximizar el porcentaje en peso de molibdeno en el cátodo desde una solución acuosa acidulada compuesta por trióxido de molibdeno, sulfato de cobalto y citrato. La razón de ...
-
(Universidad de Chile, 2011)El objetivo principal de este estudio fue comprobar el efecto de tener cobre (Cu) en solución al momento de electro-depositar renio (Re), luego se cambiaron distintos parámetros de trabajo (como la temperatura, agitación ...
-
(Universidad de ChileCyberDocs, 2010-01-15)El objetivo principal del presente trabajo de título es generar conocimiento que contribuya al desarrollo de nuevas tecnologías en la producción industrial de renio, enfocándose en la obtención del metal desde soluciones ...
-
(Elsevier Ltd, 2019)Dielectric elastomers have been regarded as truly artificial muscles for their electro-mechanical (EM) actuation performance. However, they require large driving voltages to present adequate actuation strains. The main ...
-
(BioMed Central, 2014)Background: Tissue injury has been employed to study diverse biological processes such as regeneration and inflammation. In addition to physical or surgical based methods for tissue injury, current protocols for ...
-
(MDPI, 2020)Applying electrical stimulation (ES) could affect different cellular mechanisms, thereby producing a bactericidal effect and an increase in human cell viability. Despite its relevance, this bioelectric effect has been ...
-
(MDPI AG, 2019)© 2019 by the authors.The flexibility in polymer properties has allowed the development of a broad range of materials with electroactivity, such as intrinsically conductive conjugated polymers, percolated conductive ...
-
(1997)Background: The adverse effects of cocaine use mainly occur in the heart and central nervous system. Aim: To study the effects of cocaine base paste consumption on the cardiovascular system. Subjects and methods: Thirty ...
-
(2011)Background: Ambient particulate matter (PM) derived from coal-fired power plants may have important cardiovascular effects, but existing toxicological studies are inadequate for understanding these effects. The Toxicological ...
-
(1960)The electrocadiograms of 13 patients with myocardial infarction and left bundle branch block are analyzed. The diagnosis of the infarction was based on autopsy (6 cases), on typical electrocardiographic changes in some ...
-
(Springer, 2016)We report that glassy carbon electrode (GCE) modified with multiwalled carbon nanotubes (MWCNTs) can encapsulate or entrap 3,5-dinitrobenzoic acid (35DNB) generating a 35DNB-MWCNTGC electrode. After electrochemical reduction ...
-
(Elsevier, 2015)Rhenium oxides are materials of interest for applications in the catalysis of reactions such as those occurring in fuel cells and photoelectrochemical cells. This research work was devoted to the production of rhenium oxide ...
-
(Wiley-VCH Verlag, 2018)We report the advantages of hybrid nanomaterials prepared with electrogenerated ferrites (MFe2O4; M: Co, Mn) and multi-walled carbon nanotubes (MWCNTs) or thermally reduced graphene oxide (TRGO) on the electro-reduction ...
-
(1994)We have investigated the electrocatalytic activity of vitamin B12 adsorbed on ordinary pyrolytic graphite (OPG) for the oxidation of cysteine and glutathione and for the reduction of cystine, using cyclic voltammetry and ...
-
(Elsevier, 2020)In this work, we have both synthesized and studied 4-phenylbutyl-3,5-dinitrobenzoate (3,5-DNBPh) as a potential precursor of an electrocatalytic mediator for the oxidation of NADH, with the di-nitro compound immobilized ...
-
(Sociedad Chilena de Química, 2018-03)A carbon paste electrode was modified with the ionic liquid 1-methyl-3-octyl imidazolium hexafluorophosphate and it was applied for study the electrocatalytic oxidation and voltammetric determination of the drug sulfamethazine. ...
