TL;DR: The antibacterial properties of silver modified montmorillonites from Pellegrini Lake, Argentina were tested in growth inhibition of Escherichia coli bacteria as discussed by the authors, and the results showed that the antibacterial activity is generated by the Ag + present in the clay, as confirmed by X-ray photoelectronic spectroscopy (XPS); however the overall antibacterial performance is affected by the availability of the ionic silver to be in contact with the bacteria.

TL;DR: In this article, the average crystallite size of the various phases, lattice cell parameters, phase concentrations, and titanium cationic defects in the crystalline structures of different samples were quantitatively determined.

TL;DR: KYNA, in addition to be a well-known antagonist acting on nicotinic and NMDA receptors, can be considered as a potential endogenous antioxidant.

TL;DR: In this article, high specific surface areas (77-244m 2 /g) were obtained for Titania-zirconia mixed oxides with various ZrO 2 content in TiO 2 (10, 50 and 90 ¼ ) by the sol-gel method.

TL;DR: In this paper, the synthesis conditions of supported metal catalysts using sol-gel method are reviewed, and potential applications of these materials are presented with emphasis on: thermally resistant materials, catalysts with low deactivation rates, high surface area materials and catalytic membrane reactors.
