Synchronous fluorescence spectrometry: Conformational investigation or inner filter effect?
(Elsevier Science, 2013-01)
Synchronous fluorescence spectrometry has become a common tool to investigate conformational changes in proteins due to the presence of other molecules (quenchers). The same pattern is always followed, leaving aside the ...
Screening analysis of biodiesel feedstock using UV-vis, NIR and synchronous fluorescence spectrometries and the successive projections algorithm
(Elsevier Science, 2012-08)
This paper investigates the use of UV-vis, near infrared (NIR) and synchronous fluorescence (SF) spectrometries coupled with multivariate classification methods to discriminate biodiesel samples with respect to the base ...
Determination of salicylate in blood serum by flow injection with immobilized salicylate hydroxylase
(Aoac InternationalGaithersburgEUA, 2001)
On line kinetic analysis of permeation profiles for UV filter loaded microemulsions using an automatic system with spectroscopic detection and a chemometric approach
(Royal Society of Chemistry, 2021-04-26)
The analysis of the permeation kinetics of new UV filter formulations is of great importance since the kinetic parameters are related to the effectiveness of the product over time. The dynamics of this process can be ...
Two-dimensional linear discriminant analysis for classification of three-way chemical data
(Elsevier Science, 2016-09-28)
The two-dimensional linear discriminant analysis (2D-LDA) algorithm was originally proposed in the context of face image processing for the extraction of features with maximal discriminant power. However, despite its ...
Evaluación del potencial de detección y determinación mediante fluorescencia de excitación–emisión de metabolitos de hidrocarburos aromáticos asociados a la industria del petróleo
(Bogotá - Ingeniería - Maestría en Ingeniería - Ingeniería AmbientalUniversidad Nacional de Colombia - Sede Bogotá, 2020-07-12)
Globally, industrial discharges with a high xenobiotic load are discharged to water sources. For example, in the Colombian Orinoco region, at the wellhead ~ 16 barrels of water are produced for each barrel of oil. Even ...
Determinação de hidrocarbonetos policíclicos aromáticos utilizando calibração multivariada
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2017-01-31)
A method was developed to determine low molecular weight polycyclic aromatic hydrocarbons (naphthalene, anthracene, fluorantene, phenanthrene and acenaphthene) in aqueous leachates from soils and sediments using a salting-out ...
Aplicaciones de técnicas espectroscópicas para el análisis de suelos
(Universidad Militar Nueva Granada, 2016)
Generación de Quimiosensores del Nanocomposito Celulosa Bacteriana/Puntos Cuánticos como Indicador de Contaminación por Metales Pesados en Muestras Acuosas
(Universidad Santo TomásPregrado Química AmbientalFacultad de Química Ambiental, 2021-03-15)
In the last decade, contamination by heavy metals in aqueous media has become a global problem that has increased with the confluence of natural sources and, mainly, anthropogenic activities (industrial activities, mining ...
