Refractive index spectroscopy and Material Dispersion in fused silica glass.
Optics letters, 2020Co-Authors: Yago Arosa, Raúl De La FuenteAbstract:In this study, we aimed to measure Material Dispersion in fused silica using a low coherence interferometric method. The measurement was carried out quickly and efficiently in a wide spectral range using this method. The refractive index and group index of fused silica were determined by capturing a few interferograms. The Material Dispersion was modeled using a Sellmeier equation with three resonances. Three different fits were investigated; the most appropriate fit was the one that used both the measured refractive and group indexes to model the Dispersion. Second-order Dispersion was also quantified, and zero-Dispersion wavelength was determined.

An experimental and computational study on the Material Dispersion of 1-alkyl-3-methylimidazolium tetrafluoroborate ionic liquids
Physical chemistry chemical physics : PCCP, 2020Co-Authors: Carlos Fernández, Yago Arosa, Bilal S. Algnamat, Elena López Lago, Raúl De La FuenteAbstract:The Material Dispersion of the [Ckmim][BF4] (k = 2, 3, 4, 6, 7, 8, 10) family of ionic liquids is measured at several temperatures over a broad spectral range from 300 nm to 1550 nm. The experimental curves are fitted to a modified three-resonance Sellmeier model to understand the effects of temperature and alkyl chain length on the Dispersion behaviour. From the parameters of the fitting, we analyze the influence that the different constituents of these ionic liquids have on the Dispersion behaviour. In addition, a semi-empirical approach combining simulated electronic polarizabilities and experimental densities for predicting the Material Dispersion is successfully tested by using a direct comparison with the experimental results. The limitations of this method are analyzed in terms of the molecular structure of the ionic liquids. The results of this work aim to increase our knowledge about how the molecular structure of an ionic liquid influences its Material Dispersion. Understanding this influence is fundamental to producing ionic liquids with tailored optical properties.

Consequence Modelling for Estimating the Toxic Material Dispersion Using ALOHA: Case Studies at Two Different Chemical Plants
Proceedings, 2018Co-Authors: Azizan Ramli, Norfaridah Abdul Ghani, Norhaniza Abdul Hamid, Mohd Shaiful Zaidi Mat DesaAbstract:Industrial disaster does not only result in enormous calamities and huge property damages but also deteriorate the environment especially when it involved hazardous Materials. The occurrence of major accident at major hazard installation (MHI) is unpredictable. Therefore, both structural and non-structural measures should come in the forefront before it claims human life and tremendously destroy the assets and environment. Thus, the main objectives of this study is to simulate the consequence modelling due to toxic Materials Dispersion (sulfuric acid) and subsequently suggest the evacuation mapping. The Areal Location Hazardous Atmosphere (ALOHA Version 5.4.7) was used to determine the threat zone and estimates the radius of toxic Material Dispersion from the source point. Two petrochemical plants were selected in this study and both are located at different petrochemical industrial estates in East Coast Region of Peninsular Malaysia. Based on the findings, it can be concluded that the radius of toxic Material affects the adjacent facilities and other chemical plants in proximity. The threat zones with the radius of 0.72 miles (red), 2.6 miles (orange) and 6.0 miles (yellow) respectively were determined for the first case study. As for the latter, the threat zones are greater than 6 miles for all zones. Based on both estimations, the evacuation mappings were proposed by sketching the map from Google satellite in the MARPLOT application.
