Atropisomerism is a type of stereoisomerism that results from severely hindered rotation around a single bond. If the barrier to rotation is sufficiently high then the two atropisomers will be stable ...

Pharmaceutical process chemists use resolutions, or the separation of enantiomers from racemic mixtures, more than 60% of the time to generate chiral compounds. Among resolution methods, ...

Conservation scientists have developed a new technique to authenticate and determine the age of silk artifacts... The new method uses the natural deterioration of silk's amino acids to determine its ...
