  • Patent number: 8227171
    Abstract: A photosensitive monolayer is self-assembled on an oxide surface. The chemical compound of the photosensitive monolayer has three components. A first end group provides covalent bonds with the oxide surface for self assembly on the oxide surface. A photosensitive group that dissociates upon exposure to ultraviolet radiation is linked to the first end group. A second end group linked to the photosensitive group provides hydrophobicity. Upon exposure to the ultraviolet radiation, the dissociated photosensitive group is cleaved and forms a hydrophilic derivative in the exposed region, rendering the exposed region hydrophilic. Carbon nanotubes or nanocrystals applied in an aqueous dispersion are selectively attracted to the hydrophilic exposed region to from electrostatic bonding with the hydrophilic surface of the cleaved photosensitive group.

  • Patent number: 7901977
    Abstract: Electronic assemblies, especially one containing volatile memory, used a flexible membrane with conducting lines which acts as an intrusion sensor against chemical and mechanical attacks. The lines are fabricated from inherently conducting polymers which are solution processed and directly patterned. The material was applied to a flexible polymer film by spin coating and patterned by application of a resist, followed by exposure/development of the resist and transferring the image into the polyaniline by reactive ion etching techniques. The conducting lines have high conductivity, tranparency properties which made them difficult to detect and possess excellent adhesion to the substrate film, as well as to the potting material which enclosed the structure. They also offered lightweight advantages over conventionally filled materials. These materials can also be used in conjunction with conventional conductor materials to further enhance protection against intrusion by sophisticated mechanical means.

  • Patent number: 7053401
    Abstract: Soluble, photosensitive precursors of pentacene are synthesized by a one-step Diels-Alder reaction of pentacene with N-sulfinylamides. These precursors may include a photopolymerizable group, which renders the pentacene precursor as a negative tone resist. The pentacene precursor may also include an acid-sensitive protecting group, which in the presence of a photoacid generator and upon exposure to UV light, is removed and the product becomes base soluble. Patterned pentacene thin films may be obtained by exposure to UV light through a mask and/or heating, and used as an active channel material for an organic field effect transistor.

  • Patent number: 4681698
    Abstract: An electrochemical cell having an anode, a cathode and an aqueous alkaline electrolyte solution. The anode is an intimate gelled mixture of a powdered metal, an aqueous electrolyte solution and an agent capable of gelling the mixture. The agent is a material capable of absorbing water and having a carbohydrate backbone which has a water soluble side chain grafted thereon. A preferred agent is a water insoluble salt of an aqueous alkali saponified gelatinized starch having a water soluble side chain grafted thereon. The gelling of the intimate mixture of the powdered metal anode and electrolyte solution with the agent is a method of improving the discharge characteristics of the cell.
