Phosphonate mesoporous hybrid thin films: Synthesis of organophosphosilane by thiol-ene click chemistry and applications in formation and stabilization of silver nanoparticles
(Elsevier Science, 2020-03)
The synthesis of hybrid inorganic organic mesoporous films with pores displaying phosphonic acid functions and their use as template for Ag nanoparticles are presented here. The Photochemical radical thiol – ene addition ...
Kinetics and Mechanism of Gas-Phase Thermolysis Using Headspace-Gas Chromatographic Analysis
(Oxford University Press, 2001-02)
Headspace gas chromatography is employed in order to study the thermal decomposition reaction of gaseous di-tert-butyl peroxide (DTBP) in the 130°C to 160°C temperature range and in the presence of n-hexane as the internal ...
Synthetic organometallic radical chemistry in water
(Bentham Science Publishers, 2009-04)
Several organic radical transformations in aqueous media using organometallic chemistry are presented. Group XIV-elements, such as Si and Ge, and Sn-centered radicals make use of novel methodologies in water which employ ...
Dimensional stability, fire performance and decay resistance in wood impregnated with Alkylalkoxysilanes
(World Scientific, 2013-11)
The wood, very heterogeneous and complex material, changes its volume by water absorption or desorption causing swelling or shrinkage and also it can be degraded both by action of microorganisms and fire; the above-mentioned ...
Very efficient and broad-in-scope palladium-catalyzed Hiyama cross-coupling: The role of water and copper(I) salts
(Royal Society of Chemistry, 2015-03)
A very high-yielding Pd-catalyzed cross-coupling between aryl halides and aryl(trialkoxy)silanes is achieved in the presence of Cu(i) and a measured amount of water. This novel methodology is useful for the generation of ...
Fullerene-silicon polymerization evidence
(Open Access Text, 2017-12)
We report experimental results for C<sub>60</sub>-Si deposition by simultaneous thermal vaporization of fullerene source and chemical vapor deposition from silane source. The samples were characterized by Scanning Electron ...
Luminescence properties and ROS generation of magnetic porous silicon nanoparticles
(Elsevier Science, 2020-05)
Magnetite‒Porous Silicon 100−150 nm size nanoparticles (MPSi) were obtained combining luminescent and magnetic properties from silicon and magnetite, respectively. MPSi hybrids were characterized by high-resolution ...
Carboxylic multi-walled carbon nanotubes as immobilized stationary phase in capillary electrochromatography
(Wiley VCH Verlag, 2008-12)
Carboxylic multi-walled carbon nanotubes (c-MWNT) have been immobilized into a fused-silica capillary for capillary electrochromatography. The c-MWNT were successfully incorporated after the silanization and coupling with ...
Biorecognition and detection of antigens from Mycobacterium tuberculosis using a sandwich ELISA associated with magnetic nanoparticles
(Elsevier, 2022)
Tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB), is one of the 10 leading causes of death worldwide, especially in low-income areas. A rapid, low-cost diagnostic assay for TB with high sensitivity and specificity ...
Influence of Chemically Treated Palygorskite Over the Rheological Behavior of Polypropylene Nanocomposites
