Detection of adulterations in fruit juices using machine learning methods over FT-IR spectroscopic data
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-03)
Article
Accés obertFruit juices are one of the most adulterated beverages, usually because of the addition of water, sugars, or less expensive fruit juices. This study presents a method based on Fourier transform infrared spectroscopy (FT-IR), ... -
Estudio de sensores poliméricos basados en mallas quirúrgicas termosensibles para detección por espectroscopía SERS
(Universitat Politècnica de Catalunya, 2022-05-18)
Treball Final de Grau
Accés obertAquest Treball de Fi de Grau tracta d'una investigació per desenvolupar un sensor basat en malles quirúrgiques de polipropilè isotàctic (iPP) que permet una detecció per espectroscòpia Raman amplificada per la superfície ... -
Influence of size reduction of fly ash particles by grinding on the chemical properties of geopolymers
(Multidisciplinary Digital Publishing Institute, 2018-03-02)
Article
Accés obertChemical properties of geopolymers were evaluated from the reduction of fly ash particle size by grinding. X-ray diffraction determined that at early curing ages new crystalline phases appear in the matrix of the geopolymer ... -
Simultaneous monitoring of curing shrinkage and degree of cure of thermosets by attenuated total reflection fourier transform infrared (ATR FT-IR) spectroscopy
(2013-12)
Article
Accés restringit per política de l'editorialWe present a novel methodology to simultaneously monitor of the degree of cure and curing shrinkage of thermosetting formulations. This methodology is based on the observation of changes in the infrared absorption of ...
