  • Patent number: 11511345
    Abstract: This invention relates to the nano metal material preparation technology field, especially to the preparation method of one kind, of nano-rings. This invention uses polyvinyl pyrrolidone of different molecular weights as surface-protecting agent and dissolves silver nitrate in the low molecular weight polyvinyl pyrrolidone ethylene glycol solvent under frozen conditions. Frozen conditions can slow down or inhibit silver ions from being reduced to zero-valent silver, to generate silver nanoparticles coated and complexed with both low and high molecular weight polyvinyl pyrrolidone. Polyvinyl pyrrolidone of different molecular weight shows different selective absorption of silver, and different stability makes it affect the speed of growth of silver atoms along different crystal faces to different extent, which is better for silver nano-ring production, with higher yield.

  • Patent number: 11515418
    Abstract: A tunneling transistor is implemented in silicon, using a FinFET device architecture. The tunneling FinFET has a non-planar, vertical, structure that extends out from the surface of a doped drain formed in a silicon substrate. The vertical structure includes a lightly doped fin defined by a subtractive etch process, and a heavily-doped source formed on top of the fin by epitaxial growth. The drain and channel have similar polarity, which is opposite that of the source. A gate abuts the channel region, capacitively controlling current flow through the channel from opposite sides. Source, drain, and gate terminals are all electrically accessible via front side contacts formed after completion of the device. Fabrication of the tunneling FinFET is compatible with conventional CMOS manufacturing processes, including replacement metal gate and self-aligned contact processes. Low-power operation allows the tunneling FinFET to provide a high current density compared with conventional planar devices.

  • Patent number: 9522388
    Abstract: A nanoparticle comprises a nano-active material and a nano-support. In some embodiments, the nano-active material is platinum and the nano-support is alumina. Pinning and affixing the nano-active material to the nano-support is achieved by using a high temperature condensation technology. In some embodiments, the high temperature condensation technology is plasma. Typically, a quantity of platinum and a quantity of alumina are loaded into a plasma gun. When the nano-active material bonds with the nano-support, an interface between the nano-active material and the nano-support forms. The interface is a platinum alumina metallic compound, which dramatically changes an ability for the nano-active material to move around on the surface of the nano-support, providing a better bond than that of a wet catalyst. Alternatively, a quantity of carbon is also loaded into the plasma gun.

    Abstract: Process and apparatus for functionalizing and/or separating graphene particles and other nanomaterials in which graphene and other nanoparticles are placed in a pile on one of two opposing conductive surfaces that are charged with a high D.C. voltage so that material of a certain character is attracted to the other conducting surface. This process takes place in an enclosed chamber that has been flooded with a designated gas at ambient pressure, with the material attracted to the second conducting surface passing through the designated gas. The high energy field creates a condition such that the material remaining on the first conductive surface takes on atoms of the designated gas and material the going to the second surface is further exposed to and characterized by the designated gas.

  • Publication number: 20140269830
    Abstract: Systems and methods related to the determination of one or more mechanical characteristics of a structural element are generally described. In some embodiments, a mechanical characteristic (e.g., a crack, a deformation, an inclusion, etc.) can be determined based at least in part upon the determination of a temperature generated, for example, by passing a current through a network of structures within the structural element. For example, in some embodiments, the structural element can comprise a network of electrically conductive nanostructures and, in some cases, a primary structural material that is not substantially electrically conductive. An electrical current can be passed through the network of electrically conductive nanostructures (e.g., by passing current through an electrical circuit comprising the network of electrically conductive nanostructures). This may result in resistive heating (also known as Joule-effect heating) of the nanostructure network.

  • Patent number: 8835215
    Abstract: A simple method is developed in the present invention for fabricating periodic ripple microstructures on the surface of an ITO film by using single-beam femtosecond laser pulses. The periodic ripple microstructures composed of self-organized nanodots can be directly fabricated through the irradiation of the femtosecond laser, without scanning. The ripple spacing of ˜800 nm, ˜400 nm and ˜200 nm observed in the periodic ripple microstructures can be attributed to the interference between the incident light and the scattering light of the femtosecond laser from the surface of the ITO film. In the present invention, the self-organized dots are formed by the constructive interference formed in the surface of the ITO film, where includes higher energy to break the In—O and Sn—O bonds and then form the In—In bonds. Therefore, the dots have higher surface current greater than other disconstructive regions of the ITO film.

  • Patent number: 8809492
    Abstract: Systems and methods are provided for filtering a fluid containing nanoparticles. The systems and methods generally include introducing a stream of the nanoparticle-containing fluid into a holding vessel, and extracting at least a part of a nanoparticle-containing fluid accumulated in the holding vessel. The extracted nanoparticle-containing fluid is passed through a filtration module to separate a nanoparticle-containing retentate from a permeate, and the retentate is returned to the vessel. The filtration cycle can be repeated until a desired concentration of the nanoparticles is achieved in the holding vessel. In many embodiments, the generation of the nanoparticle-containing fluid and its filtration are performed concurrently.

  • Patent number: 8771933
    Abstract: This invention provides methods utilizing a microfluidic device that can quickly and accurately discern differences in deformability between individual cells and sets of cells and continuously fractionate populations of cells based on their deformability. This information may be important in disease diagnosis and treatment efficacy monitoring. For example such a device may be able to determine the stage of malarial infection by using red blood cell deformability. Additionally, methods of the invention may be used as a tool to screen drugs that can make cells more flexible in diseases such as sickle cell anemia that causes sickle cell crises. The relatively low manufacturing and operation costs of methods of the invention enable this device to be used in resource-limited settings to diagnose and monitor disease.
