Love triumphs over hate to make exotic new compound: Compound could be useful in batteries, semiconductors, memory devices - A graduate student had a hunch for creating an exotic new chemical compound, and his idea that the force of love is stronger than hate proved correct. He and his colleagues are the first to permanently interlock two identical tetracationic rings that normally are repelled by each other. Many experts had said it couldn't be done. The new compound has attractive electronic characteristics and can be made quickly and inexpensively.(10.1126/science.1228429)
