  • Publication number: 20130148413
    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+.

  • Publication number: 20040005105
    Abstract: A new electro-optic (EO) phase modulator constructed from a combination of a low-loss passive polymer waveguide and a self-assembled chromophore superlattice (SAS) with an intrinsically polar microstructure. In contrast to typical polymer-based modulators, the present invention utilizes a siloxane SA methodology that enables the acentric alignment of constituent chromophores during film growth without the need for post-deposition electric field poling. The guiding layer is constructed of the SAS and the glassy polymer Cyclotene™. The use of SiO2, Cytop™ and Cyclotene™ glassy polymers, results in a straightforward device fabrication process that is compatible with the thermally and photochemically robust SAS. Thus, nanoscale control of the film architecture results in greatly simplified macroscopic device fabrication. The present invention provides a SAS-based electro-optic modulator demonstrating excellent electro-optic response properties and a &pgr; phase shift.
