  • Patent number: 7682650
    Abstract: An improved process for the creation or formation of nanocrystalline layers on substrates' surfaces is provided. The process involves “prescuffing” the surface of a substrate such as a metal by allowing friction to occur on the surface by a load-bearing entity making rubbing contact and moving along and on the substrate's surface. The “prescuffing” action is terminated when the coefficient of friction between the surface and the noise is rising significantly. Often, the significant rise in the coefficient of friction is signaled by a change in pitch of the scuffing action sound emanating from the buffeted surface. The “prescuffing” gives rise to a harder and smoother surface which withstands better any inadequate lubrication that may take place when the “prescuffed” surface is contacted by other surfaces.

  • Publication number: 20090263912
    Abstract: A microfluidic optical sensor utilizes at least one subwavelength nanowire or nanoribbon waveguide coupled to a fluidic structure having at least one nanofluidic channel through which one or more molecular species are conveyed. In response to optical pumping (e.g., a laser source) the waveguide optically interrogates nearby molecular species retained within said fluidic structure to detect chemical species in response to optical characterization of small (on the order of sub-picoliter) volumes of solution. Characterization is performed in response to evanescent wave sensing. In one aspect, optical characterization is selected from the group of optical characterizations consisting of absorbance, fluorescence and surface enhanced Raman spectroscopy (SERS).

  • Publication number: 20090263724
    Abstract: The invention relates to a nanostructured material. The material is a nanostructured carbonaceous material composed of agglomerates of small needles of Li1+?V3O8 and of ?-LixV2O5 (0.1 ???0.25 and 0.03 ?×?0.667) surrounded by a noncontinuous layer of spherical carbon particles. It is obtained by a process consisting in preparing a carbonaceous precursor gel by bringing carbon, ?-V2O5 and a Li precursor into contact in amounts such that the ratio of the [V2O5]/[Li] concentrations is between 1.15 and 1.5 and that the (carbon)/(carbon+V2O5+Li precursor) ratio by weight is from 10 to 15 and in subjecting the gel to a heat treatment comprising a 1st stage at 80° C.-150° C. for 3-12 h and a 2nd stage between 300° C. and 350° C. for 10 min to 1 hour, under an nitrogen or argon atmosphere.

  • Publication number: 20090233156
    Abstract: A cell-array battery is disclosed having end-of-life cells that can be activated at the end of a battery's life to, illustratively, neutralize the toxic chemicals inside the battery. In one embodiment, neutralization of the electrolyte in the battery is achieved through immobilization of the electrolyte at the end of the life of the battery by, for example, a vitrification process. Using electrowetting techniques, the electrolyte is made to contact a neutralizing substance between the nanostructures in one or more end-of-life cells, thus causing a reaction that results in the electrolyte becoming immobilized by, for example, a polymer substance. In a second illustrative embodiment, when the electrolyte contacts the substance between the nanostructures in one or more end-of-life cells, the chemical composition of the electrolyte is changed into a less toxic chemical compound, thus neutralizing the electrolyte.

  • Publication number: 20090225310
    Abstract: A surface-enhanced Raman spectroscopy (SERS) substrate formed from a plurality of monolayers of polyhedral silver nanocrystals, wherein at least one of the monolayers has polyvinypyrrolidone (PVP) on its surface, and thereby configured for sensing arsenic is described. Highly active SERS substrates are formed by assembling high density monolayers of differently shaped silver nanocrystals onto a solid support. SERS detection is performed directly on this substrate by placing a droplet of the analyte solution onto the nanocrystal monolayer. Adsorbed polymer, polyvinypyrrolidone (PVP), on the surface of the nanoparticles facilitates the binding of both arsenate and arsenite near the silver surface, allowing for highly accurate and sensitive detection capabilities.

  • Patent number: 7585584
    Abstract: Carbon nanotubes for use in a fuel cell, a method for fabricating the same, and a fuel cell using the carbon nanotubes for its electrode are provided. The internal and external walls of the carbon nanotubes are doped with nano-sized metallic catalyst particles uniformly to a degree of 0.3-5 mg/cm2. The carbon nanotubes are grown over a carbon substrate using chemical vapor deposition or plasma enhanced chemical vapor deposition. Since the carbon nanotubes have a large specific surface area, and metallic catalyst particles are uniformly distributed over the internal and external walls thereof, the reaction efficiency in an electrode becomes maximal when the carbon nanotubes are used for the electrode of a fuel cell. The carbon nanotubes fabricated using the method can be applied to form a large electrode. The carbon nanotubes grown over the carbon substrate can be readily applied to an electrode of a fuel cell, providing economical advantages and simplifying the overall electrode manufacturing process.

  • Publication number: 20090206054
    Abstract: The present invention provides patterned features of dimensions of less than 50 nm on a substrate. According to various embodiments, the features may be “Manhattan” style structures, have high aspect ratios, and/or have atomically smooth surfaces. The patterned features are made from polymer brushes grafted to a substrate. In some embodiments, the dimensions of the features may be determined by adjusting the grafting density and/or the molecular weight of the brushes. Once the brushes are patterned, the features can be shaped and reshaped with thermal or solvent treatments to achieve the desired profiles. The chemical nature of the polymer brush is thus independent of the patterning process, which allows for optimization of the polymer brush used for specific applications. Applications include masks for pattern transfer techniques such as reactive ion etching.
