The vapor pressures and vaporization enthalpies of (−) α-bisabolol and (dl)-menthol, two GRAS chemicals (generally recognized as safe) are evaluated by correlation gas chromatography using a series of saturated primary alcohols as standards. Vapor

A simulation method based on cellular automata on a hexagonal lattice is applied to model the behavior of chiral molecules on a surface, such as those in a monolayer of amphiphiles each having a single chiral center. The simulation method includes mo

An experimental system for detecting infrared absorption using the photoacoustic (PA) effect is described. It is aimed for use at high-school level to illustrate the difference in infrared (IR) absorption among the gases contained in the atmosphere i

The phenomenon originally called polyhedral flame structure was first reported 100 years ago. Subsequent investigations showed that polyhedral structure was only one example of a more general phenomenon known now as cellular flame structure, and the

Entropy Demystified seems to be intended for teachers of chemistry (or physics) rather than their students. If you are among the many for whom the concept of entropy is a bit unfocused, then this little, easy-to-read-but-not-to-browse book may be jus

Students are usually oblivious to the fate of discarded materials, and particularly to how recyclables must be processed in order to re-enter the manufacturing stream. In this activity, middle or high school students separate commingled recyclable tr
