Theoretical and experimental investigation into the IR-VUV ion dip spectroscopy of amino acids and analogue systems
… of the aliphatic amino acids, conformer specific decomposition pathways are observed spectroscopically, and further elucidated both through the study of III amino acid analogue species and through high level multiconfigurational CASSCF calculations. It is shown that upon ionization, the localized …

Biochemical alteration of gravesoils between season and soil type
Decomposition chemistry refers to the biochemical degradation processes which occur in soft tissue as decomposition proceeds. This study aims to investigate the relationship between the release of decomposition fluids into contrasting soil environments and their potential correlation with the …

Materials far from equilibrium : shock-induced deformation and chemistry in RDX and experimental development
… elsewhere. RDX has many known crystal phases and decomposition mechanisms, but how shock waves induce decomposition remains poorly understood. With in-situ single-shot X-ray diffraction experiments, we were able to measure the dynamic phase diagram of RDX for the first time, observing a phase …

Initiated chemical vapor deposition of functional polyacrylic thin films
… species. The use of low temperatures limits the decomposition chemistry to the bond scission of initiator, while retaining functional groups of monomers, which has been confirmed in the infrared spectroscopy, nuclear magnetic resonance, and x-ray photoelectron spectroscopy of iCVD poly(glycidyl …

Intramolecular carbenoid insertion : reactions of [alpha] -diazoketones derived from benzothienyl, pyrolyl and indolyl alkanoic acids with rhodium (II) acetate
… studies have shown that the rhodium (II) acetate decomposition chemistry observed for a-diazoketones tethered to thienyl, furanyl, and benzofuranyl moieties is dependent not only on the nature of the heteroatom but also on the length of the aliphatic tether linking the diazoketone moiety with the …

The kinetics and solvent effects on the thermal decomposition of isopropyl peroxide and 1, 2-dioxane
… formation have been determined for the thermal decomposition of isopropyl peroxide at l30o-l50oC in toluene and methanol and at l400C in isopropyl alcohol and water. Product studies have been carried out at l400C in these solvents. The decomposition of isopropyl peroxide was shown to be …

The kinetics and induced decomposition on the thermal decomposition of hydroperoxides /
This project is focussed on the thermsLl decomposition of t-butyl hydroperoxide and sec-butyl hydroperoxide at 120°C to 160°C in three alcohol solvents. These are methanol, ethajiol and isopropyl alcohol. The aim of the project was to examine the process of induced decomposition. Thermal …

Characterization framework to develop ball-milled thermites as additives to polymer-bound explosives
… of Al can even interfere with the primary decomposition chemistry of explosives, leading to reduced detonation velocity and peak pressure. To address these limitations, arrested reactive milling (ARM) is of interest as a customizable synthesis method for producing composite microparticles …

A study of the thermal decomposition of allyl t-butyl peroxide and 3-hydroperoxy-1-propene (allyl hydroperoxide) in toluene /|nby Krishnankutty Nair V. G. -- 260 St. Catharines [Ont. : s. n.],
Kinetics and product studies of the decompositions of allyl-t-butyl peroxide and 3-hydroperoxy- l-propene (allyl hydroperoxide ) in tolune were investigated. Decompositions of allyl-t-butyl peroxide in toluene at 130-1600 followed first order kinetics with an activation energy of 32.8 K.cals/mol …
