For decades, chemistry students have learned a simple truth: polar and nonpolar substances don’t mix. Water and oil stay ...

Chemists have made the all-cis isomer of 1,2,3,4,5,6-hexafluorocyclohexane, a crystalline ring molecule with all six fluorines pointing “up” and all six hydrogens pointing “down.” This compound is ...

This is the first installment of a three-part series about ethanol. The series focuses on physical and chemical characteristics, manufacturing processes and hazards, and firefighter response to ...

Cod liver oil and other fish oils are often used as dietary supplements because they contain nutrients such as omega-3 fatty acids, vitamin A, and vitamin D. It has been known for some time that these ...

The effect of long-chain polar compounds on the coefficient of kinetic friction under boundary conditions has been studied using the Boerlage four-ball friction apparatus in various modifications.

For the first time, scientists in Germany have successfully measured in the ozone layer the chlorine compound ClOOCl, which plays an important role in stratospheric ozone depletion. Doubts in the ...
