Modelling of optical absorption of silver NP's produced by UV radiation embedded in mesostructured silica films
(2013)
A detailed protocol is described to induce chronic stress in BALB/c mice, which affects the hypothalamic-pituitary-adrenal (HPA) axis. The protocol is based on a combination of two mild physical stressors: restraint stress ...
Polimerización en emulsión de estireno utilizando sio2: buscando una emulsión pickering
(Universidad de Costa Rica, 2021)
Photoluminescence of as-grown and thermal annealed SiOx/Si- nanocrystals heterolayers grown by reactive rf sputtering
(2012)
A macro-porous silica film served as mechanical support to immobilize TiO 2 nanoparticles, which were doped with erbium. The films and the nanoparticles were prepared by sol-gel route. The nanoparticles exhibited photocatalytic ...
New method to evaluate optical properties of core-shell nanostructures
(2012)
A new method is presented to calculate, for metallic core-dielectric shell nanostructures, the local refractive index, resonance condition, maximum spectral shift, plasma wavelength, and the sensitivity of the wavelength ...

We present an exploratory study that seeks to identify new routes for the treatment of transformer dielectric oils contaminated with polychlorinated biphenyls (PCBs), through the usage of direct reduction electrochemical ...
SiO2-Ag0 generation by sol-gel technique for antibacterial use
(2013)
Silver nanoparticles (AgNP's) have been immobilized onto silica spheres through the adsorption and subsequent reduction of Ag+ ions on the surface by trisodium citrate. The SiO2-Ag0 spheres were characterized by high ...
