New and more aggressive antibiotic resistant bacteria arise at an alarming rate represent ever-growing challenge to global health care systems. Consequently, the development of new antimicrobial agents is required overcome inefficiency conventional antibiotics bypass treatment limitations related these pathologies. In this study, we present a synthesis protocol, which was able entrap tetracycline into silica nanospheres. Bactericidal efficacy structures tested against that were susceptible...

The present study details the synthesis and characterization of a robust, monomeric Al–H aluminate supported by tridentate tris-phenolate ligand, isolated as [2][Li(THF)4] [2][N(nBu)4] salts, which were then exploited CO2 hydroboration catalysts. As initial reactivity studies, it was observed that nucleophilic anion in [2][C] (C = countercation [Li(THF)4]+ or [N(nBu)4]+) reacts fast with CO2, to afford corresponding Al-formate complexes [3][C], structurally characterized. Such anions...
Rh(0) nanoparticles (ca. 4 nm) dispersed in an ionic liquid (1-n-butyl-3-methylimidazolium tetrafluoroborate) were immobilized within a silica network, prepared by the sol–gel method. The effect of catalyst (acid or base) on encapsulated and content, morphology texture, alkene hydrogenation activity was investigated. content resulting xerogels 0.1 wt% Rh/SiO2) shown to be independent process. However, acidic conditions afforded higher contents with larger pore diameters, which turn might...
A series of silica xerogels that support Rhodamine B as a template were synthesized using distinct sol-gel routes, namely, acid-catalyzed base-catalyzed route, with (two steps) hydrolytic and FeCl3 -catalyzed nonhydrolytic route. The extraction methods (thermal, Soxhlet, water washing, ultrasound) also evaluated. resulting characterized through porosimetry nitrogen adsorption/desorption. samples further analyzed small-angle X-ray scattering, Fourier transform infrared spectroscopy, SEM....
