This 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 molecular cluster ensembles in biomatrices and the influence of ETIs; application of spectroscopic techniques in the quality control of pharmaceuticals; beer analyses in each step of the commercial production process; the properties of coagulation, flocculation, agglutination and hemagglutination; applications and uses of formic acid in liquid chromatography-mass spectrometry analysis; applications of the theory of joint probability distributions to chemical science engineering; nutritional variation in the process of brewing pilsner beer; the long-range order in MnSO4 water solutions; and the electrolytic dissociation of alkyl and aryl derivatives of malonic acid.
