Porous pure and doped silicas with pore sizes at two length scales (meso/macroporous) have been prepared shaped both as powders monoliths through a one-pot surfactant assisted procedure by using simple template agent starting from atrane complexes inorganic precursors.
Nanoparticulated bimodal porous silicas (NBSs) with pore systems structured at two length scales (meso- and large-meso-/macropores) have been prepared through a one-pot surfactant-assisted procedure by using simple template agent starting from silicon atrane complexes as hydrolytic inorganic precursors. The final bulk materials are constructed an aggregation of pseudospherical mesoporous primary nanoparticles process, over the course which interparticle (textural) large system is generated....
We present here a new family of bimodal porous silicas with organically modified surfaces or frameworks constructed from mesoporous primary nanoparticles. These organosilicas, denoted HPNOs, have been synthesized through one-pot surfactant-assisted procedure by using simple commercial template agent in triethanolamine/water media.
Abstract Silica‐based nanoparticulated bimodal mesoporous materials with high Zr content (43 ≥ Si/Zr 4) have been synthesized by a one‐pot surfactant‐assisted procedure from hydroalcoholic medium using cationic surfactant (CTMABr = cetyltrimethylammonium bromide) as structure‐directing agent, and starting molecular atrane complexes of Si hydrolytic inorganic precursors. This preparative technique allows optimization the dispersion guest species in silica walls. The nature final surface area...
Nanosized Ti-UVM-7 materials with a hierarchical system of pores at two different length scales have been prepared through one-pot procedure by using simple template agent; the catalytic activity and selectivity resulting in bulky olefin epoxidation organic peroxides are highest reported to date.
Nanomaterials with very specific features (purity, colloidal stability, composition, size, shape, location…) are commonly requested by cutting-edge technologic applications, and hence a sustainable process for the mass-production of tunable/engineered nanomaterials would be desirable. Despite this, tuning nano-scale when scaling-up production nanoparticles/nanomaterials has been considered main technological barrier development nanotechnology. Aimed at overcoming these challenging frontier,...
Ordered mesoporous TiO2–NiTiO3 thin films, with nickel content x < 0.5, were prepared by dip-coating an acidic solution of hydrolysed transition metal chlorides in controlled humidity, followed a very careful annealing treatment. These latter treatments studied situ SAXS-WAXS experiments involving synchrotron radiation and TEM analysis. They revealed that the walls can be composed amorphous, single crystalline or multi nanoparticles depending on conditions applied during thermal
We report a new development of the so-called MSU route, first route to use nonionic surfactants and block-copolymers, for synthesis silica with bimodal porosity in micromesoporous range. Among different strategies that have been explored until now, "two-step" process led formation stable hybrid micelles before condensation. This mechanism provided large freedom adjustment reaction parameters consequently final material structure. here these are enough allow them be concentrated through...

UTILIZING ARTIFICIAL INTELLIGENCE AS A TOOL TO ENHANCE STUDENT PARTICIPATION IN THE CLASSROOM THROUGH EFFECTIVE EVALUATION OF RESEARCH WORKS' QUALITY
LEVERAGING ARTIFICIAL INTELLIGENCE AND PROBLEM-BASED LEARNING TO FOSTER CRITICAL ANALYSIS SCIENTIFIC COMMUNICATION IN GRADUATE STUDENTS
Many optical sensors exploit the interesting properties of porous materials, as they ensure a stronger interaction between light and analyte directly within structure. Most are mainly based on silicon anodized aluminum oxide, showing high sensitivities. However, top-down strategies usually employed to produce those materials might offer limited control over layer, which could affect homogeneity, reducing sensor reproducibility. In this work, we present bottom-up synthesis mesoporous TiO2...

Porous materials are currently the basis of many optical sensors because their ability to provide a higher interaction between light and analyte, directly within structure. In this study, mesoporous TiO2 layers were fabricated using bottom-up synthesis approach in order develop sensing structures. comparison with more typical top-down fabrication strategies where bulk constitutive material is etched obtain required porous medium, use potentially allows increasing interconnectivity pore...
