Determination of the superficial citral content on microparticles: An application of NIR spectroscopy coupled with chemometric tools
(Elsevier Ltd, 2019)
This work evaluates near-infrared (NIR) spectroscopy coupled with chemometric tools for determining the superficial content of citral (SCCt) on microparticles. To perform this evaluation, using spray drying, citral was ...
Electrochemical Tuning of Localized Surface Plasmon Resonance in Copper Chalcogenide Nanocrystals
(American Chemical Society, 2017-07-24)
In this work, we developed a method to study in situ the optical properties of Cu2-xSe and CuS nanocrystals upon electrochemical reduction and oxidation. Both these materials possess a strong localized surface plasmon ...

Flours are products obtained from edible parts of one or more species of cereals, legumes, fruits, seeds, tubers and rhizomes by milling and / or other technological processes considered safe for food production. Wheat ...
Desenvolvimento de novos fluoróforos emissores no infravermelho baseados em sistemas híbridos moleculares doador-aceptor (D-A)
(Universidade Federal de Minas GeraisUFMG, 2019-05-10)
The present Doctoral Thesis reports the synthesis, characterization and investigation of the photoluminescent properties of some new tailored design highly conjugated donor-acceptor (D-A) molecular hybrids for the development ...
Assessing soil water repellency of a sandy field with visible near infrared spectroscopy
(Scopus, 2015)
Soil water repellency (WR) is a widespread phenomenon caused by aggregated organic matter (OM) and layers of hydrophobic organic
substances coating the surface of soil particles. These substances have a very low surface ...
Abordagens sintéticas visando a preparação de bacterioclorinas de alta conjugação
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2016-02-12)
Bacteriochlorins are porphyrin derivatives containing two reduced
peripheral double bonds (FIGURE 1). These compounds present, as their main
properties, intense absorption bands close to the Near Infrared (NIR, 750-900
nm) ...
Caracterização de Filmes a-C:H:Cl e a-C:H:Si:Cl produzidos por deposição à vapor químico assistido por plasma (PECVD) e deposição e implantação iônica por imersão em plasma (PIIID)
(Universidade Estadual Paulista (Unesp), 2015-12-21)
Este trabalho tem por finalidade a deposição de filmes finos de carbono amorfo hidrogenado (a-C:H) e de filmes finos de carbono amorfo hidrogenado com silício (a-C:H:Si). Analisar a incorporação gradativa de cloro nos ...
Er3+-doped niobium alkali germanate glasses and glass-ceramics: NIR and visible luminescence properties
(Elsevier B.V., 2019-10-01)
Niobium alkali germanate glasses doped with Er3+ up to 4.0 mol% were synthesized by the melt-quenching technique. Glass-ceramics were obtained by controlled heat treatment of the pristine glass. Thermal and optical properties ...
