(Phys.org)—Aromatic molecules are a staple of organic chemistry. Aromatics, like benzene, have a unique pi-electron character that makes the ring structure exceptionally stable. While aromatics are typically reserved for ...
DNA is synonymous with life, but where did it originate? One way to answer this question is to try to recreate the conditions that formed DNA's molecular precursors. These precursors are carbon ring structures with embedded ...
