Estudios mecanísticos y cinéticos empleando micro-reactores espectroscópicos
(2016-03-17)
Interpretar adecuadamente las interacciones moleculares, los mecanismos de reacción y la cinética intrínseca es de fundamental importancia para realizar un diseño racional de nuevos catalizadores. En esta tesis doctoral ...
Micro-Raman spectroscopy and complementary techniques applied for the analysis of rock art paintings at the archaeological locality La Angostura, lower valley of Chubut River (Patagonia, Argentina)
(Springer Science and Business Media Deutschland GmbH, 2021-03-26)
In this paper, we characterized for the first time the painting materials in rock art panels of the Patagonian archaeological locality La Angostura using a methodological approach that combined micro-Raman spectroscopy, ...
Estudio de reacciones catalíticas en la interfase líquido/sólido por espectroscopía infrarroja operando
(Academia Nacional de Ciencias Exactas, Físicas y Naturales, 2015-12)
La espectroscopia infrarroja en modo de reflexión total atenuada (ATR-IR) es unaherramienta poderosa para investigar mecanismos de reacción en sistemaslíquido(reactivo)/sólido(catalizador). Normalmente, los catalizadores ...
Effect of ceramic shade on the degree of conversion of a dual-cure resin cement analyzed by FTIR
(2013-03-01)
Objectives: The aim of this research was to evaluate the degree of monomer conversion of different resin cement shades when photocured under different feldspathic ceramic shades. The photocuring time was also evaluated as ...

Microespectroscopia no infravermelho médio por transformada de Fourier no modo reflexão total atenuada e técnicas quimiométricas aplicadas à detecção de fraudes em documentos
(Universidade Federal de Minas GeraisUFMG, 2015-02-25)
Crossing lines, ink dating and chemical erasure are some of the major problems that confront analysis of questioned documents. Conventional magnification techniques do not provide conclusive results for samples of overlapping ...
Avaliação térmica e estrutural do bagaço de cana de açúcar pré-tratado com ozônio, ultrassom e micro-ondas para produção de etanol celulósico por hidrólise enzimática
(Universidade Estadual Paulista (Unesp), 2015-05-12)
In Brazil ethanol is produced mainly from sugar cane, fiber sugarcane bagasse is mainly composed of lignin, cellulose and hemicellulose, which can produce cellulosic ethanol from saccharification of cellulose present in ...
