Modeling re-absorption of fluorescence from the leaf to the canopy level
(Elsevier Science Inc, 2017-11-07)
Chlorophyll fluorescence is widely used as an indicator of photosynthesis and physiological state of plants. Remote acquisition of fluorescence allows the diagnosis of large field extensions, even from satellite measurements. ...
Re-absorption and scattering of chlorophyll fluorescence in canopies: A revised approach
(Elsevier Science Inc., 2020-09)
The measurement of chlorophyll fluorescence in remote way represents a tool that is becoming increasingly important in relation to the diagnosis of plant health and carbon budget on the planet. However, the detection of ...
On the origins of the absorption spectroscopy of pterin and Re(CO)3(pterin)(H2O) aqueous solutions. A combined theoretical and experimental study
(Elsevier, 2014-04)
The origins of the absorption spectroscopy of pterin and Re(CO)3(pterin)(H2O) complex as a function of pH is studied using the hybrid functional B3LYP and PBE0 in combination with 6-311++G(d,p) and LanL2TZ(f) basis sets. ...
Re-evaluation of the steady-state self-quenching constant of quinine bisulphate from fluorescence measurements in transmission geometry
(IOP Publishing Ltd, 2017-09)
In the present work we show that a recent methodology developed by us to acquire emission spectra and fluorescence quantum yields of highly absorbing samples in transmission configuration, constitutes a very simple and ...
Dual Emission of a Novel (P,N) Re-I Complex: A Computational and Experimental Study on [P,N-{(C6H5)(2)(C5H4N)P}Re(CO)(3)Br]
(American Chemical Society, 2015)
The spectroscopic, electrochemical, and photophysical properties of the new complex [P,N-{(C6H5)(2)(C5H4N)-P}Re(CO)(3)Br] are reported. The UV-vis spectrum in dichloromethane shows an absorption maximum centered at 315 rim ...
Spectral redistribution of waveguided emission in BEH-PPV films
(Taylor & Francis Ltd, 2002-01-01)
We report on spectral redistribution of the photoluminescence (PL) emission from the edge of thin-film planar waveguides of the conjugated polymer BEH-PPV [Poly(2,5-bis(2'-ethyl-hexyl)-1,4-phenylenevinylene] induced by ...

We're Chained: an analysis of systemic risk in finance
(2015-08-14)
This dissertation presents two papers on how to deal with simple systemic risk measures to assess portfolio risk characteristics. The first paper deals with the Granger-causation of systemic risk indicators based in ...
