A cup of coffee isn\u2019t simply water and caffeine; it\u2019s a mixture of various chemical compounds, many of which contribute to its flavor, aroma and other characteristics. Removing caffeine while leaving the things that make coffee taste like coffee means distinguishing between molecules at an extraordinarily small scale.<\/p>\n<p>For UNSW Team Graphene master\u2019s research student Yihan Tian, the challenge had plenty of appeal.
