摘要:
Nanoparticle compositions include a plurality of spherical-shaped nanoparticles and a plurality of coral-shaped metal nanoparticles, each coral-shaped metal nanoparticle having a non-uniform cross section and a globular structure formed by multiple, non-linear strands joined together without right angles. The nanoparticle compositions can be one-part or multi-part compositions. Nanoparticle compositions can have a mass ratio of spherical-shaped to coral-shaped nanoparticles of about 5:1-20:1, about 7.5:1-15:1, about 9:1-11:1, or about 10:1 and/or a number ratio of spherical-shaped to coral-shaped nanoparticles of about 50:1-200:1, about 75:1-150:1, about 90:1-110:1 or about 100:1. The nanoparticle compositions can be used for various purposes, including as an antimicrobial (e.g., anti-viral, anti-bacteria, or anti-fungal composition), fuel additive, or treating fabrics.

An optical-microwave-quantum transducer can include a first nanophotonic slab and a second nanophotonic slab. Each of the first and second nanophotonic slabs can include an optical region and a superconducting region. The first nanophotonic slab can include a pair of torsional beams anchored to a substrate to allow relative rotation between the first and second nanophotonic slabs about an axis of rotation. The optical-microwave-quantum transducer can include a gap between the optical region of the first and second nanophotonic slabs that forms an optical cavity in response to an optical signal, wherein the optical cavity can induce mechanical oscillation of the first nanophotonic slab about the axis of rotation. The mechanical oscillation can induce electrical modulation on a superconducting cavity coupled to the superconducting regions of the first and second nanophotonic slabs.

Claimed methods reduce leakage currents in transparent conductive films comprising conductive nanostructures without substantially impairing the films' optical properties or physical integrity. Imposition of electrical stimuli to separate conductive regions leads to reduced conductivity of the intervening lesser conductive regions.

A method of creating a semiconductor device is disclosed. An end of a carbon nanotube is unzipped to provide a substantially flat surface. A contact of the semiconductor device is formed. The substantially flat surface of the carbon nanotube is coupled to the contact to create the semiconductor device. An energy gap in the unzipped end of the carbon nanotube may be less than an energy gap in a region of the carbon nanotube outside of the unzipped end region.

摘要:
A multi-walled titanium-based nanotube array containing metal or non-metal dopants is formed, in which the dopants are in the form of ions, compounds, clusters and particles located on at least one of a surface, inter-wall space and core of the nanotube. The structure can include multiple dopants, in the form of metal or non- metal ions, compounds, clusters or particles. The dopants can be located on one or more of on the surface of the nanotube, the inter-wall space (interlayer) of the nanotube and the core of the nanotube. The nanotubes may be formed by providing a titanium precursor, converting the titanium precursor into titanium-based layered materials to form titanium-based nanosheets, and transforming the titanium-based nanosheets to multi-walled titanium-based nanotubes.

Semiconductor devices having modulated nanowire counts and methods to form such devices are described. For example, a semiconductor structure includes a first semiconductor device having a plurality of nanowires disposed above a substrate and stacked in a first vertical plane with a first uppermost nanowire. A second semiconductor device has one or more nanowires disposed above the substrate and stacked in a second vertical plane with a second uppermost nanowire. The second semiconductor device includes one or more fewer nanowires than the first semiconductor device. The first and second uppermost nanowires are disposed in a same plane orthogonal to the first and second vertical planes.

The present disclosure provides an article having (a) a substrate having a first nanostructured surface that is antireflective when exposed to air and an opposing second surface; and (b) a conductor micropattern disposed on the first surface of the substrate, the conductor micropattern formed by a plurality of traces defining a plurality of open area cells. The micropattern has an open area fraction greater than 80% and a uniform distribution of trace orientation.

Each of the traces has a width from 0.5 to 10 micrometer. The articles are useful in devices such as displays, in particular, touch screen displays useful for mobile hand held devices, tablets and computers. They also find use in antennas and for EMI shields
摘要:
An electrochromic device (ECD) includes an electrochromic cell and, optionally, one or more additional electrochromic cells where all cells are parallel, and where at least one of the electrodes of one of the cells comprises a single-walled carbon nanotube (SWNT) film. The electrochromic cells allow the control of transmittance of two or more di fferent portions of the electromagnetic spectrum through the ECD. One cell can control the transmittance of visible radiation while the other cell can control the transmittance of IR radiation. The ECD can be employed as a "smart window" to control the heat and light transmission through the window. The ECD can be in the form of a laminate that can be added to an existing window.
