Nano-osciladores por transferencia de Spin, un modelo que va más allá de la aproximación macro-spin (Universidad de Chile, 2016)El objetivo general de este trabajo es estudiar la dinámica de la magnetización, tanto en el régimen lineal como no lineal, de la capa ferromagnética libre de una estructura nanopilar, cuando se inyecta una corriente ...
-
(Taylor and Francis Ltd., 2020)We study a nanocomposite consisting of a ferroelectric liquid crystal and a magnetic nanoparticle in order to explore the possibility of using it as a magnetic resonant imaging contrast agent which will measure a field of ...
-
(Universidad de Chile, 2020)Enfermedades asociadas a la degeneración del tejido cartilaginoso representan un elevado costo en la calidad de vida de quienes la padecen, produciendo dolor y discapacidad motora, además de un considerable gasto público. ...
-
(Elsevier, 2016)Carbon nanostructures were prepared by RF magnetron sputtering at deposition times from 30 to 120 min and temperatures on silicon substrates from 390 degrees C to 510 degrees C. Scanning and transmission electron microscopy ...
-
(Universidad de Chile, 2022)Las emisiones de Gases de Efecto Invernadero a nivel mundial son los responsables del calentamiento global. El uso de energías renovables pueden reducir el uso de los combustibles fósiles, encargados de la producción del ...

(SOC BIOLGIA CHILE, 2011)After the progress made during the genomics era, bioinformatics was tasked with supporting the fl ow of information generated by nanobiotechnology efforts. This challenge requires adapting classical bioinformatic and ...
-
(Elsevier, 2016)Two ethylene-1-butene thermoplastic elastomer copolymers were melt mixed with different nanometric fillers such as: multi-walled carbon nanotubes (CNT), thermally reduced graphite oxide (TrGO), and spherical metal ...
-
(Universidad de Chile, 2022)Space agencies, educational institutions, and private companies have adopted CubeSat nanosatellites to do scientific research, training, technology demonstration, and space-based industries in the New Space era. The next ...
-
(Walter de Gruyter GmbH, 2018)We report new results of a combined focused ion beam and high-resolution transmission electron microscopy (FIB/HRTEM) investigation of platinum-group elements (PGE)-rich base-metal sulfides. The Ni-Fe-Cu base-metal ...
-
(Wiley-VCH Verlag, 2019)In the present work, finite element simulations to investigate nanosecond pulsed laser ablation of stainless steel under low laser fluence conditions is performed. The laser has a wavelength of 1064 nm as well as a Gaussian ...
-
(HINDAWI PUBLISHING CORP, 2016)A theoretical wireless nanosensor network (WNSN) system that gives information about the food packaging condition is proposed. The protection effectiveness is estimated by measuring many factors, such as the existence of ...
-
(Elsevier B.V., 2019)In this work, precipitation and sol-gel mixed procedures were used to prepare a TiO2@Fe3O4 nanocomposite. The X-ray diffraction (XRD)and selected area electron diffraction (SAED)results unmistakably elucidated the tetragonal ...
-
(Elsevier, 2020)Colourful dyes are primarily used in the textiles, toys, food, inks, paper and plastics. These dyes are water soluble and contaminate the water. The dyes are not bio-degradable and sustain in the water for long time create ...
-
(Elsevier, 2017)We demonstrate that the anodization of copper in alkaline water/ethylene glycol media containing fluoride ions generates nanostructured copper oxide films. By modifying the anodization conditions (fluoride and OH– ...
-
(Universidad de Chile, 2021)La presente investigación se centra en analizar las políticas culturales de fomento de la lectura en Chile, formuladas y diseñadas por el Consejo Nacional de la Cultura y las Artes durante su existencia, entre los años ...
-
(EDP Sciences, 2021)Context. We initiated a deep-imaging survey of Scorpius-Centaurus A-F stars in 2015. These stars are predicted to host warm inner and cold outer belts of debris reminiscent of the architecture of emblematic systems such ...
