Detection of Organic Vapors Using Tamm Mode Based Devices Built from Mesoporous Oxide Thin Films
(Wiley VCH Verlag, 2019-10)
In this work, Tamm mode based devices were synthesized using mesoporous thin films as building blocks. Several systems were designed and built, based on silicon and titanium mesoporous oxides obtained through amphiphilic ...
Bimetallic ag-au nanoparticles inside mesoporous titania thin films: Synthesis by photoreduction and galvanic replacement, and catalytic activity
(Wiley VCH Verlag, 2020-02)
In this work, the synthesis and catalytic activity of bimetallic Ag–Au nanoparticles (NPs) supported in TiO2 mesoporous thin films (MTFs) are presented. The composite materials were obtained through a two-step procedure, ...
Selective SERS Sensing Modulated by Functionalized Mesoporous Films
(American Chemical Society, 2015-11)
A hybrid material comprising metal nanoparticles embedded in functionalized mesoporous thin films was constructed, and its use as a selective SERS-based sensor was demonstrated. The presence of specific functional groups ...
Silver Nanoparticle-Mesoporous Oxide Nanocomposite Thin Films: A Platform for Spatially Homogeneous SERS-Active Substrates with Enhanced Stability
(American Chemical Society, 2014-03)
We introduce a nanoparticle-mesoporous oxide thin film composite (NP-MOTF) as low-cost and straightforward sensing platforms for surface-enhanced Raman Spectroscopy (SERS). Titania, zirconia, and silica mesoporous matrices ...
Mesoporous Thin Films for Acoustic Devices in the Gigahertz Range
(American Chemical Society, 2020-06)
The coherent manipulation of acoustic waves on the nanoscale usually requires multilayers with thicknesses and interface roughness defined down to the atomic monolayer. This results in expensive devices with predetermined ...
Sol–gel synthesis of mesoporous CaCu3Ti4O12 thin films and their gas sensing response
(Elsevier, 2010-04-01)
A new sol–gel synthesis procedure of stable calcium copper titanate (CaCu3Ti4O12—CCTO) precursor sols for the fabrication of porous films was developed. The composition of the sol was selected in order to avoid the ...
Synthesis and applications of mesoporous nanocomposites containing metal nanoparticles
(Springer, 2014-04)
Metal nanoparticles (NP) and mesoporous (MP) oxides are complementary materials, since the size scale of pores in MP oxides matches that of NP and both systems have potential applications in similar fields. Besides, ...
Mesoporous titania coating: determination of its physicochemical properties and yeast behavior
(2019)
We have synthesized titania mesoporous films using titanium (IV) chloride as sol-gel precursor and surfactants from Pluronics® (Pluronic F-127, POE-POP-POE) and Brij ? series (B96 y B58, alquil-POE) that act like molds for ...
Mesoporous thin film structures as metal nanoparticle reactors for electronic circuits: Effects of matrix crystallinity and nanoparticle functionalization
(Academic Press Ltd - Elsevier Science Ltd, 2017-09)
There is an increasing interest in versatile nanoelectronic structures based on stable, accessible and spatially located arrays of metal nanoparticles. In this study, the influences of mesoporous titania thin film crystallinity ...
TiO2 mesoporous thin film architecture as a tool to control Au nanoparticles growth and sensing capabilities
(Royal Society of Chemistry, 2019-04)
In this paper, a systematic study regarding the effect of the mesoporous structure over Au nanoparticles (NPs) growth inside and through the pores of mesoporous TiO2 thin films (MTTFs) is presented, and the effect of such ...
