Nanoelectronic differential amplifiers and related circuits implemented on a segment of a graphene nanoribbon

Номер: US20120001689A1

Автор: Lester F. Ludwig

Принадлежит: Pike Group LLC

A multiple transistor differential amplifier is implemented on a segment of a single graphene nanoribbon. Differential amplifier field effect transistors are formed on the graphene nanoribbon from a first group of electrical conductors in contact with the graphene nanoribbon and a second group of electrical conductors insulated from, but exerting electric fields on, the graphene nanoribbon thereby forming the gates of the field effect transistors. A transistor in one portion of the graphene nanoribbon and a transistor in another portion of the graphene nanoribbon are responsive to respective incoming electrical signals. A current source, also formed on the graphene nanoribbon, is connected with the differential amplifier, and the current source and the differential amplifier operating together generate an outgoing signal responsive to the incoming electrical signal. In an example application, the resulting circuit can be used to interface with electrical signals of nanoscale sensors and actuators,

Принадлежит: UNITED ARAB EMIRATES UNIVERSITY

We disclose a process to produce carbon nanotubes from microalgae. Microalgae is been utilized for biodiesel production. The algal membrane resulted from oil extraction of microalgae is used here to produce carbon nanotubes. The process utilized for the conversion is composed of two steps, in the first step the algal membrane is converted to carbon black through a pyrolysis process in inert atmosphere, in the second step the resulted carbon black is converted to carbon nanotubes by mixing the carbon black with a fluid with known self ignition condition and subjecting the mix to said self ignition condition.

Принадлежит: Ostendo Technologies Inc

Extremely high efficiency solar cells are described. Novel alternating bias schemes enhance the photovoltaic power extraction capability above the cell band-gap by enabling the extraction of hot carriers. In conventional solar cells, this alternating bias scheme has the potential of more than doubling their yielded net efficiency. In solar cells incorporating quantum wells (QWs) or quantum dots (QDs), the alternating bias scheme has the potential of extending such solar cell power extraction coverage, possibly across the entire solar spectrum, thus enabling unprecedented solar power extraction efficiency. Within such cells, a novel alternating bias scheme extends the cell energy conversion capability above the cell material band-gap while the quantum confinement structures are used to extend the cell energy conversion capability below the cell band-gap. Light confinement cavities are incorporated into the cell structure to allow the absorption of the cell internal photo emission, thus further enhancing the cell efficiency.

Immunologically modified carbon nanotubes for cancer treatment

Номер: US20120220921A1

Автор: Wei R. Chen

Принадлежит: University of Central Oklahoma

A method for constructing a compound of immunologically modified nanotubes and method for using the compound to deliver immunoadjuvants to tumor cells and to produce targeted, synergistic photophysical and immunological reactions for cancer treatment. To prepare the immunologically modified nanotubes, carbon nanotubes are dissolved in a solution of glycated chitosan, an immunostimulant, hence using glycated chitosan as a surfactant for rendering the aqueous solution of nanotubes stable. The compound can be used for treatment of cancer. The method includes steps of intratumorally administering immunologically modified nanotubes and administering laser irradiation of the target tumor. The nanotube serves as a carrier to deliver immunoadjuvants to the tumor cells and serves as a light-absorbing agent in a cell body of a tumor in a host. Upon laser irradiation of target tumor cells, immunologically modified nanotubes inside the tumor cells can produce spatially and temporally synchronized photothermal and immunological reactions for cancer treatment.

Принадлежит: The Arizona Board of Regents on Behalf of the University of Arizona

In an exemplary method, a nano-architectured carbon structure is fabricated by forming a unit (e.g., a film) of a liquid carbon-containing starting material and at least one dopant. A surface of the unit is nano-molded using a durable mold that is pre-formed with a pattern of nano-concavities corresponding to a desired pattern of nano-features to be formed by the mold on the surface of the unit. After nano-molding the surface of the unit, the first unit is stabilized to render the unit and its formed nano-structures capable of surviving downstream steps. The mold is removed from the first surface to form a nano-molded surface of a carbonization precursor. The precursor is carbonized in an inert-gas atmosphere at a suitable high temperature to form a corresponding nano-architectured carbon structure. A principal use of the nano-architectured carbon structure is a carbon electrode used in, e.g., Li-ion batteries, supercapacitors, and battery-supercapacitor hybrid devices. 1.

The nucleic acid sink molecule sequesters a putative second nucleic acid catalyst, wherein the second nucleic acid catalyst differs from the first nucleic acid catalyst molecule by at least one nucleotide. In some aspects, the first nucleic acid catalyst may include a biomarker of interest or a nucleic acid aptamer which binds an amino acid-based biomarker of interest.
