H-Bonding Enables Molecular Dancing
Hydrogen bonding plays a key role in the diffusion of organic molecules across solid surfaces in a dancelike performance, according to a study published in Science (2010, 328, 882). Previous surface studies based on area-averaging techniques have established that hydrogen adsorbed on solids influences diffusion of other adsorbates. But atomic-scale details of such diffusion processes, which can control chemical reactivity and self-assembly on surfaces, have remained largely unknown. With a combination of scanning tunneling microscopy . . .
