The authors’ of this latest volume discuss recent advances in chemistry research. Chapter One provides recent advances and developments in gliadin-based drug delivery systems. Chapter Two discusses advances achieved in the development of catalytic processes for the production of ss-citronellol derivatives as alkyl esters, aldehydes, carbamates, and carbonates. Chapter Three focuses on the developments and applications of a new type of polymer-supported organosilica layered-hybrid membranes. Chapter Four investigates the long-range order in natural oils and fats. Chapter Five reviews the possible link between the main classes content of monoterpenes and sesquiterpenes and finds a direct link between them and their antioxidant activity. Chapter Six reports on the chemical compositions and biological activities of essential oils hydrodistilled from three plants from Nigeria. Chapter Seven reviews fluorescence and phosphorescence spectra of xanthone in the vapor phase. Chapter Eight examiners mass transfer characteristics of an external loop airlift reactor. Chapter Nine studies applications of isolation and structure elucidation of secondary metabolites in a natural product chemistry laboratory.
