Fluorescence turn-on and turn-off mechanisms of a dual-selective chemosensor of Bi3+ and pH changes: Insights from a theoretical perspective
(Elsevier Ltd, 2021-02)
The N-hydroxy 1,8-naphthalimide (LH) is an optical dual-selective chemosensor toward Bi3+ ions as well as pH changes. In specific, this senor is selective to Bi3+ ions, which turn-on the fluorescence upon their interaction; ...
The association of prepartum urine pH, plasma total calcium concentration at calving and postpartum diseases in Holstein dairy cattle
(Elsevier, 2021)
The use of anionic salts to prevent milk fever in dairy cattle has been an effective nutritional strategy; however, the degree of acidification that determines the most acceptable productive responses andwell-being of the ...

Gelatin based films capable of modifying its color against environmental pH changes
(Elsevier, 2016-12)
The aim of this work was to develop biodegradable protein-based films capable of sense pH changes. These protein films were prepared by casting from aqueous solutions of bovine gelatin, glycerol and three acid-base indicators: ...
