Novel method for determination of zinc traces in beverages and water samples by solid surface fluorescence using a conventional quartz cuvette
(Elsevier, 2015-01)
A new method for zinc pre-concentration/separation and determination by molecular fluorescence is proposed. The metal was complexed with o-phenanthroline and eosin at pH 7.5 in Tris; a piece of filter paper was used as a ...
Morphology of collagen fibers and elastic system fibers in actinic cheilitis
(2010-10-01)
Background: Actinic cheilitis (AC) is a premalignant condition intimately related to exposure of the lips to sun rays. Aim: The objective of this study was to evaluate the elastic and collagen fibers in the lamina propria ...
Homogenous implant in rat tibias of matrix preserved in 98% glycerin: histomorphologic study.
(2000-12-01)
As a chemical medium for preservation of tissues, glycerin has shown good results because it maintains the cellular integrity despite the tissue dehydration it causes. Taking advantage of the osteoinducing properties of ...

Comparison of the Kinetics of Electron Transfer in the Diffusion Limit for the Singlet and Triplet Quenching of Eosin Y by Quinones
(Wiley, 2013-06)
Electron transfer (ET) rate constants were determined by means of lifetime measurements for the fluorescence quenching and by laser flash photolysis for the triplet quenching of the dye eosin Y by benzoquinones in acetonitrile. ...
