The Hiyama reaction, which features organosilicon derived cross-coupling partners with aryl chlorides, remains relatively underdeveloped compared to other cross-coupling reactions. In this thesis, it is demonstrated that bench stable Palladium N-… more Full Text: PALLADIUM N-HETEROCYCLIC CARBENE COMPLEXES IN CROSS-COUPLING REACTIONS: LIGAND AND CATALYST DEVELOPMENT A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty …

Abstract: <p>In this work, a deep learning approach proposed by Valensise et al. [3] for extracting Raman resonant spectra from measured broadband CARS spectra was explored to see how effective it is at removing NRB from our experimentally measured "spectral-focusing"-based approach to CARS. A large dataset of realistic simulated CARS spectra was used to train a model capable of performing… more Full Text: Deep learning for removal of non-resonant background in CARS hyperspectroscopy A thesis submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Art and Science Trent …

However, a broader and more detailed understanding of the frequency-time characteristics of the laser pulses and signals involved, how they are… more Full Text: FREQUENCY-TIME AND POLARIZATION CONSIDERATIONS IN SPECTRAL-FOCUSING-BASED CARS MICROSCOPY A THESIS SUBMITTED TO THE COMMITTEE ON GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN THE FACULTY OF ARTS AND …

Abstract: <p>Activated Carbon (AC) is commonly produced by gasification, but there has been increasing interest in chemical activation due to its lower activation temperatures and higher yields. Phosphoric acid, in particular, succeeds in both these areas. Phosphoric acid activated carbon (PAC) can be environmentally sustainable, and economically favourable, when the phosphoric acid used in the… more Full Text: Phosphoric Acid Chemically Activated Waste Wood: Production, Modification and Selenite and Selenate Adsorption A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements For the Degree of Master of Science in the …

Abstract: <p>This thesis explores the use of 1-butene cross metathesized palm oil (PMTAG) as a feedstock for preparation of polyols which can be used to prepare rigid and flexible polyurethane foams. PMTAG is advantageous over its precursor feedstock, palm oil, for synthesizing polyols, especially for the preparation of rigid foams, because of the reduction of dangling chain effects associated with… more Full Text: Synthesis of Lipid Based Polyols from 1-butene Metathesized Palm Oil for Use in Polyurethane Foam Applications A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Doctor of Philosophy in the Faculty …

Abstract: <p>Structure-property relationships are increasingly valued for the identification of specifically engineered materials with properties optimized for targeted application(s). In this work, linear and branched diesters for use in lubricant formulations are prepared from lipid-based oleochemicals and their structure-property relationships reported. It is shown that the branched diesters… more Full Text: NOVEL ALIPHATIC LIPID-BASED DIESTERS FOR USE IN LUBRICANT FORMULATIONS: STRUCTURE PROPERTY INVESTIGATIONS A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy in the …
