Cine en dictadura: notas acerca de la representación de la pobreza en cinco películas chilenas
(Chile. Universidad Mayor, 2019)
El propósito de este artículo es analizar la representación cinematográfca de la pobreza en cinco películas chilenas realizadas durante la dictadura militar del general Augusto Pinochet. Específcamente refexionaremos acerca ...
Layer-by-Layer-Assembled AuNPs-Decorated First-Generation Poly(amidoamine) Dendrimer with Reduced Graphene Oxide Core as Highly Sensitive Biosensing Platform with Controllable 3D Nanoarchitecture for Rapid Voltammetric Analysis of Ultratrace DNA Hybridization
(AMER CHEMICAL SOC, 2018)
The structure and electrochemical properties of layer-by-layer-assembled gold nanoparticles (AuNPs)-decorated first-generation (G1) poly(amidoamine) dendrimer (PD) with reduced graphene oxide (rGO) core as a highly sensitive ...
Ion implantation in nanodiamonds: size effect and energy dependence
(NATURE PUBLISHING GROUP, 2018)
Nanoparticles are ubiquitous in nature and are increasingly important for technology. They are subject to bombardment by ionizing radiation in a diverse range of environments. In particular, nanodiamonds represent a variety ...
Catalytic effects of p-phenylene-bridged methylated binuclear ferrocenes on thermal decomposition of the main component of composite solid propellants
(ELSEVIER SCIENCE BV, 2018)
This contribution describes the catalytic activity of homobimetallic complexes derived from p-phenylene on the thermal decomposition of ammonium perchlorate (abbreviated as AP). The complexes, [CpFe-p-Ph-FeCp] (1), ...
Structural, electronic and catalytic properties of palladium nanoparticles supported on poly(ionic liquid)
(ELSEVIER SCIENCE BV, 2018)
The structural, electronic and support effect on palladium nanoparticles (Pd NPs) prepared by sputtering deposition and chemical reduction of a Pd(II) precursor in/on a poly(ionic liquid) (PIL) was investigated in the ...
Graphene Oxide Quantum Dots as the Support for the Synthesis of Gold Nanoparticles and Their Applications as New Catalysts for the Decomposition of Composite Solid Propellants
(AMER CHEMICAL SOC, 2018)
Graphene oxide quantum dot (GOQD) and reduced GOOD (rGOQD) were synthetized using a simple and straight methodology based on an oxidative treatment and sonication. GOQD and rGOQD were used as supporting agents for the in ...
Electrochemical in situ synthesis of polypyrrole nanowires
(ELSEVIER SCIENCE INC, 2019)
Modification with polypyrrole nanowires, PPy-nw, is accomplished directly upon the working electrode by electrochemical polymerization methods using mesoporous silica as a template. The silica template is prepared by a ...
Protein capped nanosilver free radical oxidation: role of biomolecule capping on nanoparticle colloidal stability and protein oxidation
(ROYAL SOC CHEMISTRY, 2018)
We studied the effect of human serum albumin protein capped spherical nanosilver on the nanoparticle stability upon peroxyl radical oxidation. The nanoparticle-protein composite is less prone to oxidation compared to the ...
Layer-by-layer assembled gold nanoparticles/lower-generation (Gn <= 3) polyamidoamine dendrimers-grafted reduced graphene oxide nanohybrids with 3D fractal architecture for fast, ultra-trace, and label-free electrochemical gene nanobiosensors
(ELSEVIER ADVANCED TECHNOLOGY, 2018)
Three layer-by-layer (LBL) assembled gold nanoparticles (AuNPs)/lower-generation (Gn <= 3) polyamidoamine dendrimer (PD) with reduced graphene oxide (rGO) as the core/mercaptopropinoic acid (MPA)/Au were successfully ...
Euterpe oleracea Mart. Inhibits virulence factors of Aspergillus fumigatus
(Chile. Universidad Mayor, 2019)
Aim: Euterpe oleracea Mart. (acai) presents organic compounds with different pharmacological properties. The aim was to evaluate the bioactivity of the acai extract on the virulence factors of two strains of Aspergillus ...
