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 determination of hydrate stability zones of sour gases using a two parameter model; the bio-protective effectiveness of trehalose against man-made electromagnetic fields; acetone tautomerism; nano-sized carbon-coated li4ti5o12 particles with enhanced high-rate performance for lithium-ion batteries; evaluation of the experimental data for gas solubility in liquid water in equilibrium with gas hydrates; computation of the second virial coefficient of chemical compounds using a corresponding states based method; computer aided molecular design by using property cluster and molecular matrix; multi residue method for determination of fifty-five pesticide residues in pomegranate samples by gas chromatography coupled with triple quadrupole tandem mass spectrometry using the quechers extraction method; and metrological key concepts applied to chemical and pharmaceutical testing laboratories.
