Styrylpyrylium Dyes as Solvent-Sensitive Molecules Displaying Dual Fluorescence
(Wiley, 2017-08-31)
A series of new molecules showing solvent-sensitive UV/Vis spectroscopic properties have been synthesized and characterized. The new compounds share a common 6-styryl-2,4-disubstituted pyrylium architecture, which allows ...
The interaction of amino acids with macrocyclic pH probes of pseudopeptidic nature
(Royal Society of Chemistry, 2017)
The fluorescence quenching, by a series of amino acids, of pseudopeptidic compounds acting as probes for cellular acidity has been investigated. It has been found that amino acids containing electron-rich aromatic side ...
Karrooite green pigments doped with Co and Zn: Synthesis, color properties and stability in ceramic glazes
(Elsevier, 2017-08-15)
The solid-state synthesis and stabilization of Co doped (Mg1−xCoxTi2O5), Zn doped (Mg1−xZnxTi2O5) and Co- and Zn-codoped karrooite solid solutions (Mg0.8−xZn0.2CoxTi2O5 and (Mg0.5Zn0.5)1−xCoxTi2O5) were investigated. In ...
Antiplasmodials soulattrolide derivatives from Calophyllum brasiliense and its mechanism of activity
(Elsevier, 2019-03)
Parasitic diseases such as malaria, leishmaniasis, trypanosomia-sis, and schistosomiasis are just one of the main causes of diseaseand death in the world today (WHO, 2016). In 2016, 91 countriesreported a total of 216 ...
Improving photocatalytic oxygenation mediated by polymer supported photosensitizers using semiconductor quantum dots as ‘light antennas’
(Royal Society of Chemistry, 2017)
Quantum dots (QDs) adsorbed on the surface of polymeric photocatalysts improved the photochemical generation of singlet oxygen due to the efficient energy transfer process from the semiconductor nanoparticles to the bound ...
Combustion synthesis, structural and magnetic characterization of Ce1-xPrxO2 system
(Springer, 2017-07)
The current work describes the synthesis of Ce1−xPrxO2 (x = 0.0, 0.2, 0.4, 0.6, 0.8) and Pr6O11 systems by the combustion method, using citric acid as chelating agent. The obtained solids after combustion and calcination ...
Morphology Diversity of L‐Phenylalanine‐Based Short Peptide Supramolecular Aggregates and Hydrogels
(Wiley, 2018-08)
Supramolecular aggregates and hydrogels of diverse morphologies can be obtained by replacing the widely studied aromatic N‐capping of phenylalanine derivatives by long alkyl chains. Simple changes in chain length and number ...
Synthesis and biological evaluation of cyclic derivatives of combretastatin A-4 containing group 14 elements
(Royal Society of Chemistry, 2018)
Several tricyclic compounds inspired by the structure of combretastatin A-4 and bearing group 14 elements have been synthesized by homocoupling lithiated aryl fragments followed by ring-closing metathesis. These tricyclic ...

En el presente trabajo se describe una experiencia educativa con alumnos de tercer curso de Educación Secundaria Obligatoria, centrada en los contenidos de “La formulación química inorgánica”. Desde una pregunta o desde ...
A Chalcone-Based Highly Selective and Sensitive Chromofluorogenic Probe for Trivalent Metal Cations
(Wiley, 2017)
A new chalcone-based probe for the chromofluorogenic sensing of trivalent (Al3+, Fe3+, Cr3+, Ga3+, In3+ and As3+) over mono- and divalent cations and anions is reported. In the presence of trivalent metal cations, the probe ...
