  • Patent number: 9685619
    Abstract: 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.

  • Publication number: 20150303390
    Abstract: The present invention relates to a device having an electrically conductive surface and carrying a molecular assembly, preferably composed of two or more redox-active based molecular components arranged in a specific order or sequence, such that the sequence of the components and their thickness dictate the assembly properties and consequently the uses of the device. Such a device can be used in fabrication of a multistate memory, electrochromic window, smart window, electrochromic display, binary memory, solar cell, molecular diode, charge storage device, capacitor, or transistor.

  • Patent number: 8917539
    Abstract: 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.

  • Patent number: 8273576
    Abstract: The present invention relates to a molecular-based system for the optical detection, quantification and detoxification of hexavalent chromium (Cr6+) by reversible metal-substrate electron transfer. More particularly, the invention provides a Cr6+ sensor device comprising a divalent osmium (Os2+)-, iron (Fe2+)- or ruthenium (R2+)-based pyridyl complex capable of changing its oxidation state in response to a reduction of Cr6+ at the presence of H+, thereby causing a reversible and optically readable change in optical properties of said complex. The Os2+-, Fe2+- or R2+-based pyridyl complex used according to the invention can be used for selective detection and quantification of Cr6+, as well as for catalytic detoxification of Cr6+.
