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 catalysis for nitrous oxide abatement; bioelectrocatalysis with P450 cytochromes; application of nitrous oxide for chemical vapour deposition of thin films used in integrated circuit technology; bromination of organic substrates with special reference to green chemistry; synthesis of binaphthyl based monophosphorus ligands; surface modification of sulfide minerals in bioflotation with hydrophobic and hydrophilic bacteria; application of chronopotentiometry in the over-limiting current density range of ion exchange membranes to determine the diffusion coefficients of electrolytes; ensembles of molecular clusters in water HCl solutions; molecular clusters in H2SO4 and its water solutions; water polymorphism influences on the dissolution enthalpy of NaCl mechanisms; and the PES of formaldehyde through vibrational excitations.
