  • Patent number: 7836752
    Abstract: A nanoscale antiferromagnetic gas sensing apparatus and methods of measuring gas using the apparatus are described. The use of the magnetic properties of an antiferromagnetic material as gas sensing parameters explores the concept of magnetic gas sensing. According to a preferred embodiment, a nanoscale magnetic hydrogen sensor apparatus is developed based on varying of the saturation magnetization and remanence of nanoscale antiferromagnetic hematite with hydrogen flow. For example, the saturation magnetization and remanence of nanoscale hematite has been shown to increase one to two orders of magnitude in the presence of flowing hydrogen gas at concentrations in the 1-10% range and at 575 K, indicating that a magnetic hydrogen sensor using hematite material may be practical and useful for detecting hydrogen in various environments such as those wherein production, storage, transportation, and/or vehicle use of hydrogen is being conducted.

  • Publication number: 20100103495
    Abstract: A high-speed optical modulator based on Surface Plasmon-Polariton (SPP) at the hetero-junction of a metal-insulator-semiconductor (MIS) tunneling diode and including a phase-matching optical element, such as a prism or gold-lattice structure, is described. An investigation using the coupled mode theory shows that the applied bias across the hetero-junction changes the optical reflectance of an optically coupled MIS tunneling diode, such as a prism-coupled MIS tunneling diode or a gold lattice-coupled MIS tunneling diode, while the modulation efficiency achievable of the device depends on the thickness of the metal film used to construct the tunneling diode.

  • Publication number: 20090136580
    Abstract: Here we disclose the response of normal human cells to ZnO nanoparticles under different signaling environments and compare it to the response of cancerous cells. ZnO nanoparticles exhibit a strong preferential ability to kill cancerous T cells (˜28-35X) compared to normal cells. Interestingly, the activation state of the cell contributes toward nanoparticle toxicity as resting T cells display a relative resistance while cells stimulated through the T cell receptor and CD28 costimulatory pathway show greater toxicity in direct relation to the level of activation. The novel findings of cell selective toxicity towards potential disease causing cells indicate a potential utility of ZnO nanoparticle in the treatment of cancer and/or autoimmunity.

  • Publication number: 20080143195
    Abstract: A magnetomechanical transducer, and apparatus and methods using said magnetomechanical transducer, extract electrical power from any motion, including random motion, cyclic, and vibrational motion. The motion is transferred to linear motion through a mechanical connecting device to the magnetomechanical coupler, which comprises a magnetoplastic and/or magnetoelastic material that transduces the linear motion into a change of magnetic field, via twin boundary deformation. A bias magnetic field assures a net change of magnetization during said deformation. A further transducer, e.g. a coil or a Hall element, couples the magnetic field change to an electrical output. A restoring field or device, for example the bias magnetic field or a device that produces strain in a reverse direction, resets the magnetomechanical transducer to its initial state. The magnetomechanical transducer may be provided in microgenerators that capture kinetic energy and convert it to electrical power.

  • Publication number: 20080121859
    Abstract: Non-volatile memory devices with two stacked layers of chalcogenide materials comprising the active memory device have been investigated for their potential as phase change memories. The devices tested included GeTe/SnTe, Ge2Se3/SnTe, and Ge2Se3/SnSe stacks. All devices exhibited resistance switching behavior. The polarity of the applied voltage with respect to the SnTe or SnSe layer was critical to the memory switching properties, due to the electric field induced movement of either Sn or Te into the Ge-chalcogenide layer. One embodiment of the invention is a device comprising a stack of chalcogenide-containing layers which exhibit phase change switching only after a reverse polarity voltage potential is applied across the stack causing ion movement into an adjacent layer and thus “activating” the device to act as a phase change random access memory device or a reconfigurable electronics device when the applied voltage potential is returned to the normal polarity.

  • Patent number: 6692627
    Abstract: The present invention is an apparatus and a process for separation and resolution of particles suspended in, or molecules dissolved in, a sample mixture or solution using electrical field flow fractionation (EFFF). Fractionation of individual components in the mixture/solution is obtained by the interaction of particles/molecules with an electric field applied perpendicular to the flow direction, and externally to the fractionation channel. The plate electrodes are electrically isolated from the sample and carrier within a thin, non-permeable, insulating coating on the inside surfaces electrodes. This coating forms a barrier between the solution phase and the electric circuit used to generate the working electric field. The flow channel is formed by sandwiching a shaped insulating gasket between the two parallel plate electrodes. The side walls of the channel are defined then by the inside walls of the shaped, insulating gasket.
