Leggere, scrivere, ricordare con le molecole

Energy- and signal-processing at a molecular level relies on cause/effect relationships between the input supplied and the kind of process obtained. Energy- and signal-processing at the molecular level have been classified according to the nature of the input (electronic, photonic, or chemical) and the nature of the obtained effect (electronic, photonic, or chemical process that follows). By coupling the three kinds of inputs with the three types of resulting processes, nine types of molecular-based processes (electronic, photonic, chemionic, electrophotonic, electrochemionic, photoelectronic, photochemionic, chemiophotonic, and chemioelectronic) can be identified. In this article, looking at molecular transformations in an unconventional way a flavor of some of the new features has been given that project the old science of chemistry towards novel achievements.
