This new book presents original research results on the leading edge of chemistry research. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. Topics discussed include a systematic ab-initio study of electronic and vibrational properties of beryllium-vi polymorphs and their corresponding ground state and excited states using maximally-localized wannier functions; advances in spectroscopic investigations of riboflavin in aqueous solutions and milk; preservative and antitoxigenic activities of phenolic compounds; viscoelastic properties and structure of abs polymers; the study of anticoagulant properties of leucine and combined activities of its complexes with high -- molecular -- weight heparin; dyes in water; organometallic nanostructures; and experimental measurement and thermodynamic modelling.
