Application of Raman and infrared microscopy coupled with chemometrics for the forensic examination of automotive clear coats and paint smears
(2022-07)Modern automotive paints typically use thinner undercoat and color coat layers protected by a thicker clear coat layer. All too often, a clear coat is the only layer of automotive paint left at the crime scene. Current ... -
Authentication of edible oils using Fourier transform infrared spectroscopy and pattern recognition methods
(2022-07)A potential method to determine whether two edible oils can be differentiated by infrared spectroscopy is proposed. IR spectra of the pure edible oils and mixtures of these edible oils in known amounts are compared using ... -
Genetic algorithms for feature selection and classification of complex chromatographic and spectroscopic data
(2012-12)A basic methodology for analyzing large multivariate chemical data sets based on feature selection is proposed. Each chromatogram or spectrum is represented as a point in a high dimensional measurement space. A genetic ... -
Infrared microscopy and liquid chromatography applied to problems in forensics and bioanalytical chemistry
(2019-07)The main objectives of the research described in this dissertation are: (1) development of a methodology to prepare thin sections of automotive paint samples that involve exposing the edge of the sample using a microtome ...
