The assembled nanorods are suitable for use as nanoscale interconnects in CMOS-based devices and sensors. Metallic nanoparticles or carbon nanotubes are assembled into lithographically patterned vias by applying an external electric field. Since the dimensions of nanorods are controlled by the dimensions of vias, the nanorod dimensions can be scaled down to the low nanometer range. The aqueous assembly process is environmentally friendly and can be used to make nanorods using different types of metallic particles as well as semiconducting and metallic nanaotubes.

  • Publication number: 20120299124
    Abstract: A method for forming a gate structure includes the following steps. A substrate is provided. A silicon oxide layer is formed on the substrate. A decoupled plasma-nitridation process is applied to the silicon oxide layer so as to form a silicon oxynitride layer. A first polysilicon layer is formed on the silicon oxynitride layer. A thermal process is applied to the silicon oxynitride layer having the first polysilicon layer. After the thermal process, a second polysilicon layer is formed on the first polysilicon layer. The first polysilicon layer can protect the gate dielectric layer during the thermal process. The nitrogen atoms inside the gate dielectric layer do not lose out of the gate dielectric layer. Thus, the out-gassing phenomenon can be avoided, and a dielectric constant of the gate dielectric layer can not be changed, thereby increasing the reliability of the gate structure.

  • Publication number: 20120298924
    Abstract: A process for manufacturing a thermoelectric material having a plurality of grains and grain boundaries. The process includes determining a material composition to be investigated for the thermoelectric material and then determining a range of values of grain size and/or grain boundary barrier height obtainable for the material composition using current state of the art manufacturing techniques. Thereafter, a range of figure of merit values for the material composition is determined as a function of the range of values of grain size and/or grain boundary barrier height. And finally, a thermoelectric material having the determined material composition and an average grain size and grain boundary barrier height corresponding to the maximum range of figure of merit values is manufactured.

  • Publication number: 20120292184
    Abstract: A method of microbial identification is disclosed. The method includes the steps of assembling dielectrophoretic particles modified with specific DNA probes on a surface thereof in a continuous fluid at a predetermined location in a microchannel to form a particle assembly by a negative dielectrophoretic force and a hydrodynamic force provided by the continuous fluid, narrowing gaps between the dielectrophoretic particles of the particle assembly to enhance the electric field in the gaps between the dielectrophoretic particles, injecting a fluid containing target DNAs of a target microbe into the microchannel at a predetermined flow rate to move the target DNAs toward the particle assembly and generating a positive dielectrophoretic force by the enhanced electric field to attract the target DNAs toward the dielectrophoretic particles of the particle assembly for hybridization with the DNA probes. The present invention also discloses a method of manipulation of nanoscale biomolecules.

    Abstract: Gel nanoparticles for encapsulating and delivering a pharmaceutical compound to a patient. The nanoparticles are formed from N-trimethyl chitosan and polysialic acid, preferably in the presence of sodium tripolyphosphate. A ratio of polysialic acid to N-trimethyl chitosan of about 0.5 to 1 produces nanoparticles having diameter of about 100 nm (plus or minus 25 nm) and a zero potential above 30 milivolts that can stability contain a pharmaceutical compound, such as methotrexate, for delivery to a patient.
