Turbidity and dissolved organic matter as significant predictors of spatio-temporal dynamics of phosphorus in a large river-floodplain system
(John Wiley & Sons Ltd, 2018-09)
Phosphorus (P) inputs are increasing in river‐floodplain systems, but the factors whichinfluence the dynamics of this nutrient are not clear. To assess P dynamics in this kindof river, the main channel of the Middle Paraná ...
Structural control of photoluminescence of four poly(urethane-urea-co-1,3,5-triazine)s: Synthesis and characterization
(2007-06-01)
A series of segmented poly(urethane-urea)s containing 1,3,5 triazine in the hard block and hexamethylene spacers in the soft block was prepared. The hard to soft segment ratio was varied systematically, to afford a series ...

Electronic Delocalization, Vibrational Dynamics, and Energy Transfer in Organic Chromophores
(American Chemical Society, 2017-06)
The efficiency of materials developed for solar energy and technological applications depends on the interplay between molecular architecture and light-induced electronic energy redistribution. The spatial localization of ...
Raman spectroscopy of a sulfur dioxide visual sensor: The origin of the two colors in the solid sample
(ELSEVIER SCIENCE BV, 2009)
The vibrational spectroscopic characterization of a sulfur dioxide visual sensor was carried out using a Raman microscope system. It was observed the formation of two distinct complexes, that were characterized by the ...
A new highly selective chromogenic and fluorogenic chemosensor for copper (II)
(Bentham Science Publishers, 2017-12)
A new fluorogenic and chromogenic probe (L) for the selective, sensitive and naked-eye detection of Cu2+ is reported. Complexation constant, complex stoichiometry and quantum chemical (DFT) calculation for Cu2+ complex has ...
