Generation of engineered core-shell antibiotic nanoparticles
(2019)
Well-defined nanocomposite structures have received significant attention due to their superior combinatorial properties. Rational tuning of the core and shell of the nanostructure(s) can offer potent antibacterial activity. ...
Synthesis and characterization of ZrO2@SiO2 core-shell nanostructure as nanocatalyst: Application for environmental remediation of rhodamine B dye aqueous solution
(2019-05-15)
ZrO2@SiO2 core-shell nanostructures were synthesized by a facile two-step hydrothermal plus Stöber chemical route. The structure, morphology and properties of the nanoparticles were characterized using X-ray powder diffraction ...

In this work the synthesis and characterization of the magnetic nanoparticles of magnetite (Fe3O4) from the methodology via co-precipitation and its subsequent functionalization by silica (SiO2), carried out via sol-gel ...
High spectral field enhancement and tunability in core-double shell metal-dielectric-metal spherical nanoparticles
(Royal Society of Chemistry, 2016-11)
In this work we have developed full Mie theory for spherical core-double shell NPs, considering the boundary conditions of the electric and magnetic fields at each interface, to study plasmon resonances, optical extinction ...
Intra-miniband absorption coefficient in GaAs/AlxGa1−xAs core/shell spherical quantum dot
(Elsevier, 2018-03)
In this work we reported the theoretical calculations of the absorption coefficient in a GaAs/AlxGa1−xAs core/shell spherical quantum dot as a function of the aluminium concentration x in the direct band-gap regime, and ...
Ethanol oxidation reactions using SnO(2)@Pt/C as an electrocatalyst
(ELSEVIER SCIENCE BV, 2010)
This paper presents a study on the ethanol oxidation reaction using SnO(2)@Pt/C core-shell structures as electrocatalysts. All the materials used, including Pt/C and PtSn/C E-tek, were 20% (w/w) metal on carbon. The formation ...
Influence of Pt-Sn System Nanostructure on the Electronic Conditions at a Pt Adsorption Surface Site
(Amer Chemical Soc, 2018-05-31)
This paper describes the synthesis and full characterization of Pt-Sn intermetallics with the same stoichiometry and similar particle size but distinct atomic arrangements (ordered intermetallic, ordinary alloy, and ...
