A logic circuit for performing a logic operation comprising a plurality of predetermined solid-state molecular chips, each molecular chip having multiple states obtained after application of a corresponding input. After applying predetermined inputs on the molecular chips, reading the states of the molecular chips produces a logical output according to the logic operation.

A solid-state, multi-valued, molecular random access memory (RAM) device, comprising an electrically, optically and/or magnetically addressable unit, a memory reader, and a memory writer. The addressable unit comprises a conductive substrate; one or more layers of electrochromic, magnetic, redox-active, and/or photochromic materials deposited on the conductive substrate; and a conductive top layer deposited on top the one or more layers. The memory writer applies a plurality of predetermined values of potential biases or optical signals or magnetic fields to the unit, wherein each predetermined value applied results in a uniquely distinguishable optical, magnetic and/or electrical state of the unit, thus corresponding to a unique logical value. The memory reader reads the optical, magnetic and/or electrical state of the unit.

Solid, multi-state molecular random access memory

The present invention relates to a molecular-based system for the optical detection, quantification and detoxification of hexavalent chromium (Cr) by reversible metal-substrate electron transfer. More particularly, the invention provides a Crsensor device comprising a divalent osmium (Os)-, iron (Fe)- or ruthenium (R)-based pyridyl complex capable of changing its oxidation state in response to a reduction of Crat the presence of H, thereby causing a reversible and optically readable change in optical properties of said complex. The Os-, Fe- or R-based pyridyl complex used according to the invention can be used for selective detection and quantification of Cr, as well as for catalytic detoxification of Cr.
