A refractory, porous ceramic composite including crystalline mullite (3Al2O3+2SiO2 or 3Al6Si2O11) and a crystalline phase of LaPO4 is formed from a mullite-LaPO4 sol-gel by annealing the dried gel. During the annealing process, particle sintering and self-foaming occur in the glassy state, and pores are produced due at least in part to the release of entrapped gases that form during the pyrolysis of the gel. The resulting crystalline composite, or crystalline nanocomposite, has a high porosity and is dimensionally and chemically stable at high temperatures. The composite also has a high degree of structural (e.g., mechanical) stability, related at least in part to the fine texturing and mixing of the mullite and LaPO4 during preparation of the sol. The resulting ceramic composite shows little or no shrinkage or expansion between about 1000C and about 1200° C.

A product catalog includes information regarding products for sale online by various merchants, including product review information. An analysis module collects product reviews and determines whether each product review includes a product identifier, such as a Global Trade Item Number (“GTIN”). For product reviews having a product identifier, the module adds the product review to the product catalog and associates the product review with the product identifier. For product reviews lacking a product identifier, the module initiates an Internet search using information from the product review and analyzes search results to identify a product identifier for the product review. If the analysis module identifies a product identifier for the product review, the analysis module adds the product review to the product catalog and associates the product review with the identified product identifier. The analysis module may discard product reviews that are not associated with a product identifier.
摘要:
A stabilized, chemically reactive, metallic nano-material effective for degradation of chlorinated organic compounds in soils, sediments and groundwater. The nano-material is composed of a magnetic metal nanoparticle and a carbohydrate stabilizer bound to the nanoparticle. The preferred metal nanoparticle is iron and the preferred carbohydrate stabilizer is either a starch or a water soluble cellulose such as sodium carboxymethyl cellulose. The nanoparticle may be either mono-metallic, bi-metallic or multi-metallic in nature, but is preferably bi-metallic wherein it is coated with a secondary catalytic metal coating, preferably palladium. A method of making the metallic nano-material is further disclosed wherein a solution of the metal nanoparticle and carbohydrate stabilizer is prepared, and the nanoparticle is then reduced under inert conditions. A process for reductive dechlorination of chlorinated organic compounds is also disclosed wherein the reduced magnetic metal nanoparticle is prepared, and then contacted with a chlorinated organic compound to dechlorinate the compound. Preferably, the nano-material is injected into a site such as soil subsurface or groundwater contaminated with a chlorinated organic compound to provide in-situ dechlorination.

An electrical connector for mating with a plug includes an insulative housing, a number of contacts retained in the insulative housing, a metal shield and at least one metal spring fixed to the metal shield. The metal spring and the metal shield are made of different materials. The metal shield covers the insulative housing to define a receiving cavity formed by a plurality of peripheral walls. One of the peripheral walls defines a slot communicating with the receiving cavity. The metal spring is securely fixed to the peripheral walls and including an engaging arm extending into the receiving cavity through the slot.

A pneumatic card transport system is disclosed. The system is configured to use pressurized air to transport a card inserted to a conveying duct inside a card passageway assembly from a first end to a second end. Air nozzles are configured to release the pressurized airstreams at an angle relative to the conveying duct so that the card is essentially floating when traveling along the conveying duct. Hence, the card makes zero or minimum contact with the inner surface of the conveying duct. This will not only reduce the wear and tear of the card, but also reduces the traveling time inside the conveying duct.
