The nucleophilic power of the N-oxide group is related to the biological activity of quinoxaline 1,4 di-N-oxides against T. cruzi.

In order to increase accessibility to catalytic sites, studies have been carried out in order to reduce the diameter of the particles of zeolites to the nanometer scale.

Optical microscope image through PBX (80 % HMX) cluster with PBLH.

This picture depicts the scheme which has been employed in this manuscript for solvothermal synthesis of Ni-BTC. The organic linker H₃BTC was dissolved in series of solvents and solvothermally reacted with NiNO₃.6H₂O(aqueous) for the production of Ni-BTC.

The nature of M^δ+···^δ+C-O^δ- interactions in metal carbonyls can be explained through the topological analysis of the electron charge density and its Laplacian function within the framework of the Quantum Theory of Atoms in Molecules (QTAIM).

Synergetic degradation of organic substrates by TiO₂-graphene oxide nanocomposites: electron shuttling and preliminary adsorption of target compounds.

An excessive increase in surface area was observed after Cu²⁺ insertion by wet impregnation from β-Al(OH)₃ support, which is explained by the redissolution and recrystallization of bayerite to γ-Al₂O₃ during the impregnation of Cu²⁺.

Determination of tin in natural samples collected in area under anthropogenic action through atomic fluorescence spectrometry.

Sulfonated poly(vinyl alcohol) (SPVA) membranes and in situ prepared TiO₂ nanoparticles incorporated SPVA membranes are prepared to use in direct methanol fuel cell. Very low methanol permeability is observed with the prepared membranes. Proton conductivity of the membranes is higher than Nafion and high thermal stability is achieved with increased TiO₂ nanoparticles concentration.

Three extraction methods were compared (SPME, SCF and SDE) for isolation of flavor compounds from roasted ground coffee of Vilcabamba (Ecuador). Identification and characterization of volatile compounds were achieved using gas GC-MS.

A strategy for the rapid identification of fungal metabolites.

Spectrophotometric methods associated to chemometric analysis as an attractive approaching to determination of chemical modifications during UHT milk heat treatment assisting in a quality control process.

Central words of social representations of environmental education of future teachers of chemistry.

General behavior of the Shannon entropy S_x and S_p depending on the distance of confinement (x_c). Highlight that the inflection of the curves is due to the influence of confinement, while the behavior of these for large x_c tends toward a free system.

Serial precipitation of Cd²⁺, Cu²⁺, Zn²⁺, Mn²⁺ and Pb²⁺ ions forming various colored sulfides in bubblers with chemically generated hydrogen sulfide stream.
