Semiconductor device and method for manufacturing the same

A metallic oxide semiconductor device with high performance and small variations. It is a field effect transistor using a metallic oxide film for the channel, which includes a channel region and a source region and comprises a drain region with a lower oxygen content than the channel region in the metallic oxide, in which the channel region exhibits semiconductor characteristics and the oxygen content decreases with depth below the surface.

Gas Turbine Installation with Flue Gas Recirculation

A method and installation are disclosed which can, for example, provide for reliable, low-Nox-emission operation of a gas turbine installation with hydrogen-rich fuel gas. An exemplary gas turbine installation includes an arrangement for flue gas recirculation into a compressor inlet and for fuel gas dilution. Oxygen content in combustion air can be reduced by recirculation of recooled flue gas, and the fuel gas can be diluted with compressed flue gas. The oxygen reduction in the combustion air can lead to minimum residual oxygen in the flue gas which can be used for fuel gas dilution. As a result of the flue gas recirculation, water content in the combustion air can be increased by feedback of the water which results as a combustion product. The oxygen reduction, increased water content, and fuel dilution can reduce the flame velocity of hydrogen-rich fuel gases and enable a robust, reliable and low-emission combustion.

Systems, methods, and catalysts for producing a crude product

Contact of a crude feed with one or more catalysts produces a total product that includes a crude product. The crude feed may include Micro-Carbon Residue (MCR), oxygen, sulfur, or mixtures thereof. The crude product is a liquid mixture at 25° C. and 0.101 MPa. The crude product may have a MCR residue and / or oxygen content of at most 90% of the MCR residue content and / or oxygen content of the crude feed. In some instances, the crude product may have a sulfur content of about 30% to about 70% of the sulfur content of the crude feed. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

Process for producing dispersible Nano Graphene Platelets from oxidized graphite

The present invention provides a process for producing nano graphene platelets (NGPs) that are dispersible and conducting. The process comprises: (a) preparing a graphite intercalation compound (GIC) or graphite oxide (GO) from a laminar graphite material; (b) exposing the GIC or GO to a first temperature for a first period of time to obtain exfoliated graphite; and (c) exposing the exfoliated graphite to a second temperature in a protective atmosphere for a second period of time to obtain the desired dispersible nano graphene platelet with an oxygen content no greater than 25% by weight, preferably below 20% by weight, further preferably between 5% and 20% by weight. Conductive NGPs can find applications in transparent electrodes for solar cells or flat panel displays, additives for battery and supercapacitor electrodes, conductive nanocomposite for electromagnetic wave interference (EMI) shielding and static charge dissipation, etc.

Hypoxic fire prevention and fire suppression systems with breathable fire extinguishing compositions for human occupied environments

Fire prevention and suppression systems and breathable fire-extinguishing compositions are provided for rooms, houses and buildings, transportation tunnels and vehicles, underground and underwater facilities, marine vessels, submarines, passenger and military aircraft, space stations and vehicles, military installations and vehicles, and all other human occupied objects and facilities. The system provides a breathable hypoxic fire-preventative atmosphere at standard atmospheric or local ambient pressure. The system employs an oxygen-extraction apparatus supplying oxygen-depleted air inside a human-occupied area or storing it in a high-pressure container for use in case of fire. A breathable fire-extinguishing composition is introduced for constant fire-preventive environments, being mostly a mixture of nitrogen and oxygen and having oxygen content ranging from 12% to 17%. A fire-suppression system is provided employing a fire-extinguishing composition with oxygen concentration under 16%, so when released it creates a breathable fire-suppressive atmosphere having oxygen concentration of approximately 16% (or lower if needed) with possible addition of carbon dioxide. A technology for automatically maintaining a breathable fire-preventive composition on board a human-occupied hermetic object is provided by introducing inert ballast that automatically maintains oxygen content under the Hypoxic Threshold. An aircraft fire prevention and suppression systems are provided utilizing hypoxic fire extinguishing compositions for producing breathable atmosphere onboard having fire-retarding properties.
