Light propagation in turbid media: A generalization of the solution given by the diffusion approximation, based on the moments of multiple scattering
(Pergamon-Elsevier Science Ltd, 2010-11)
In this work we propose a generalization of the solution for light propagation in turbid media given by the diffusion approximation (DA), based on the calculus of the photon coordinates momenta. The main results of the ...
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 ...
Assessment of multifractal analysis in dynamic laser speckle signals using a spatial light modulator
(Optical Society of America, 2019-02)
We assess and discuss several technical aspects of the multifractal statistical analysis applied to time series of dynamic speckle intensity signals. Due to the complexity of this goal, we implemented an optical setup that ...
Depth Analysis of Chemical Environments using Resonant Raman Spectroscopy in Total Reflection Geometry
(Brazilian Association for Synchrotron Light Technology, 2010-06)
Total Reflection of X-rays is a largely proved spectroscopic technique that allows the study of material surfaces. As the refractive index is less than unity, X-rays incident on a material are, theoretically, totally ...
Oil-In-Water Microemulsions for Thymol Solubilization
(Molecular Diversity Preservation International, 2019-12)
Essential oil compounds (EOCs) are molecules with well-known antimicrobial and antipest activity. However, such molecules possess limited solubility in water, making their handling difficult. This work aimed to enhance the ...
The effect of glycation on oil–water emulsion properties of β-lactoglobulin
(Elsevier Science, 2012-03)
The creaming, flocculation and coalescence processes of destabilization of emulsions prepared with glycated β-lactoglobulin was analyzed. The glycation process was carried out with glucose and lactose in different reaction ...
Information-weighted constrained regularization for particle size distribution recovery in multiangle dynamic light scattering
(Optical Society of America, 2018-01)
In particle size measurement with dynamic light scattering (DLS), it is difficult to get an accurate recovery of a bimodal particle size distribution (PSD) with a peak position ratio less than ~2:1, especially when large ...
Triplet quantum yields in light-scattering powder samples measured by laser-induced optoacoustic spectroscopy (LIOAS)
(Royal Society of Chemistry, 2012-06)
In recent years, different methods and techniques have been applied to study the primary photophysical processes occurring in dye-loaded light-scattering powdered samples. In spite of this, there are still no reliable ...
Entrainment of circadian rhythms to irregular light/dark cycles: A subterranean perspective
(Nature Publishing Group, 2016-10)
Synchronization of biological rhythms to the 24-hour day/night has long been studied with model organisms, under artificial light/dark cycles in the laboratory. The commonly used rectangular light/dark cycles, comprising ...
