This causes the membrane to be composed of monolayers with polar groups at each end.
The effect of this is to place the polar group in between two non-polar chains.
When the ink molecules contain certain polar groups the transfer of these impurities is increased.
This means that these ions can hold onto two polar groups.
They are functionalized with polar groups, allowing their use in aqueous solutions.
In terms of stereoselectivity, polar groups act like large, bulky groups.
Even though two groups may have approximately the same A values the polar group will act as though it were much bulkier.
This is due to the donor character of the polar group.
The composition of the final polar group would be decided by Scott during the journey.
For example, the polar groups in most polymers easily bond to water.
