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 ...

In today's foods industry, it is very important to know the level of unsaturation and the relative amounts of cis and trans isomer content in edible oils and fats This is imperative in terms of ...

Chemists have found that the all-cis isomer of hexafluorocyclohexane, a molecule that made headlines last year for being the most polar aliphatic compound known, is capable of binding both cations and ...

The transition state of a polymer isomerization has been stabilized under sonication-induced elongation, leading to the formation of the less stable cis-isomer. When studying chemical reactions, ...

In today’s food industry, knowing the degree of unsaturation and relative amounts of cis and trans isomerization in edible fats and oils is vital. This is necessary for both quality and process ...
