Highly performing mesoporous nanocomposite films with embedded exfoliated graphene and gold nanoparticles display a significant enhancement of G-SERS properties.
Graphene–silica films with high optical transparency have been obtained by adding a dispersion of exfoliated graphene into silica sol.
Nanocomposite thin films formed by mesoporous titania layers loaded with ceria nanoparticles have been obtained combining bottom-up self-assembly synthesis of a matrix top-down hard X-ray lithography nanocrystalline cerium oxide. At first the mesopores impregnated precursor solution and then exposed to X-rays, which triggered formation crystalline oxides within pores inducing in situ growth average size 4 nm. It has observed that type coordinating agent plays primary role nanoparticles....
To fully exploit the potential of self-assembly in a single step, we have designed an integrated process to obtain mesoporous graphene nanocomposite films. The synthesis allows incorporating sheets with small number defects into highly ordered and transparent titania careful design porous matrix at mesoscale ensures highest diffusivity These exhibit enhanced photocatalytic efficiency, while high order mesoporosity is not affected by insertion well-preserved after controlled thermal...
The present work is aimed at developing a titania-based mesoporous film with catalytic properties toward organophosphate pesticides by combining two different approaches: the molecular imprinting and self-assembly supramolecular template. mesoporosity of material has been obtained using tri-block copolymer (Pluronic F127) as micellar template while imprinted cavities have templated complex between La3+ bis-4-nitro-phenyl-phosphate. removal allowed opening, in one step, both mesopores...
The controlled release of nanoparticles from a hybrid organic-inorganic surface allows for developing several applications based on slow delivery oxygen scavengers into specific environments. We have successfully grafted ceria film and tested their in buffer solution; the tests shown that particles are continuously delivered within time scale hours. has been synthesized using 3-glycidoxypropyltrimethoxysilane as precursor alkoxide; synthesis performed highly basic conditions to control...
Graphene sheets increase the Raman signal through a chemical enhancement mechanism that gives rise to graphene-mediated enhanced scattering (GERS). The low factor and surface available for analysis are, however, limitation on application of GERS. We have, therefore, developed new GERS platform, which is based mesoporous ordered films made titania anatase containing dispersed exfoliated graphene. analytical has revealed combination graphene produces significant in response using Rhodamine 6G...
In this paper we examine the chemical composition results obtained on a collection of 18 dinosaur fossil bones from Spain studied using portable x-ray fluorescence spectrometer together with reverse Monte Carlo numerical technique data analysis. This approach is applied to hypothesis arbitrarily rough surfaces in order account for influence surface state specimens content evaluation. It confirmed that elements essential understanding changes brought about by diagenetic and taphonomic...
Among the myriad microfabrication approaches, Deep X-ray Lithography (DXRL) takes advantage of high penetration depth hard X-rays. For first time, this feature has been exploited for precise control surface chemical functionalities on a thick porous ceramic material. As proof concept, alumina membranes with controlled thickness (50 µ m) have chosen to test potential DXRL. The Al 2 O 3 were decorated fluoro- and amino-silanes. These functionalized exposed X-rays in synchrotron facility, which...
