Volume 66 begins with a focus on the development of reproducible and economical methodologies for the separation, identification and quantification of chemical species present in oils and greases. The authors discuss the major structure-function attributes of azoles as antifungal mainstays, with an intensive focus on resistant mechanisms and concurrent remedial measures. Following this, the total syntheses of biologically active natural products achieved over the past 25 years is described. The concluding study concerns methanol, a toxic substance with a neutral, colorless liquid and a mild odor.
