On the far field optical properties of Ag-Au nanosphere pairs
(American Chemical Society, 2010-10)
In this work we study the far field optical properties of heterodimers composed of a silver and a gold nanosphere of the same size, by means of exact electrodynamics calculations based on the generalized multiparticle Mie ...
Surface plasmons induced in Al spherical nanoparticles by Auger effect
(Elsevier Science, 2016-02-15)
In this work we study the surface plasmon generation by electron-hole interaction in an aluminum spherical nano-particle due to the Auger electron-hole interaction by means of the Hamiltonian formalism.
Plasmon coupling in silver nanosphere pairs
(American Chemical Society, 2010-03)
In this work we study the optical properties of silver metal nanosphere pairs by means of rigorous electrodynamics calculations based on the generalized multiparticle Mie theory. By correlating the dipole longitudinal ...
Impact of the surface hydrophobicity/hydrophilicity ratio on the catalytic properties of Ni nanoparticles/MCM-41 system used in the hydrogenation of acetophenone
(Elsevier Science, 2021-07-11)
Three nickel catalysts were prepared supporting pre-synthetized monodisperse Ni nanoparticles of 16 nm. As support, nanospheres of MCM-41 were used. Two batches of these supports were superficially modified by silylation ...
Estabilidad de la enzima cu-zn superóxido dismutasa inmovilizada en nanosferas 100 para una formulación cosmética
(Universidad Técnica de Ambato - FCIAL, 2018)
Seed-mediated growth of jack-shaped gold nanoparticles from cyclodextrin-coated gold nanospheres
(Royal Society of Chemistry, 2013-08)
Branched gold nanoparticles were prepared by a seed-mediated approach using per-6-thio-6-deoxy-β-cyclodextrin capped gold nanospheres as seeds and a growth medium similar to those commonly employed to prepare gold nanorods, ...
Gold recycling at laboratory scale: from nanowaste to nanospheres
(Wiley VCH Verlag, 2019-11)
The market for products based on nanotechnology, and with it the use of nanomaterials and the generation of nanowaste, increases day by day. Among the vast variety of nanomaterials available, gold nanoparticles (AuNPs) are ...
Efecto de la temperatura y homogenización del Bromuro de Cetiltrimetilamonio (CTAB) en el proceso de síntesis de Nanoesferas de Au
En este trabajo se ha evaluado el efecto de la temperatura (65, 75, 85 y 95 °C) y el tipo de homogenización (agitación ultrasónica y agitación magnética) en la disolución del bromuro de cetiltrimetilamonio (CTAB), empleado ...
