Advances in Chemistry Research. Volume 71 (eBook)

This volume includes eight chapters describing recent advancements in chemistry research. Chapter One compares commercially available equipment with a novel aerosol detection and measurement method. Chapter Two is a review of preparation methods and biological activity of amino acid Schiff base compounds and their metal complexes. Chapter Three provides an insight into the antioxidant activity of eugenol, studied from its various sources and through different methods, as well as its applications in the food industry for the purpose of extending shelf life of various products. Chapter Four discusses the synthesis, luminescence and biological activities of imidazole and bicyclic imidazole derivatives. Chapter Five analyzes the current and emerging applications of various encapsulation techniques such as spray-drying, fluidized bed coating, spray-chilling, coacervation, extrusion, emulsification and freeze-drying for delivery of eugenol. Chapter Six investigates the mechanism, kinetics and thermochemistry of the gas phase reactions of methyl fluoroacetate. Chapter Seven examines in detail the health effects and sources of caffeine. Finally, Chapter Eight evaluates the cytotoxic, genotoxic, and oxidative effects of octodrine when consumed alone or with caffeine.
