  • Publication number: 20190225491
    Abstract: A method of purifying a plurality of metal oxide particles produced from a synthesis process is disclosed. The method comprises the step of washing a plurality of metal oxide particles in a first solvent composition comprising of at least one aliphatic ether, and at least one flocculant. In one embodiment, the plurality of metal oxide particles are iron oxide particles produced from a thermal decomposition synthesis process between an iron-oleate complex and oleic acid in 1-octadecene, wherein the first solvent composition comprises a 1:1 (vol/vol) ratio of an aliphatic ether in the form of diethyl ether and a flocculant in the form of methanol. The washed iron oxide particles are further washed in a second solvent composition comprising a 1:1 (vol/vol) ratio of hexane and ethanol, and then finally dispersed in hexane.

  • Publication number: 20190155262
    Abstract: A digital manufacturing system includes a web portal to receive product configuration information. An enterprise resource planning subsystem generates a production order based on the product configuration information, and determines a manufacturing resource plan and production steps for manufacturing the product. A manufacturing execution subsystem generates an identifier for the manufacturing resource plan, and communicate the manufacturing resource plan and the production steps to a production control subsystem controlling machines performing the manufacturing of the product according to the manufacturing resource plan and the production steps. A production control subsystem stores the identifier in a near field communication chip attachable to the product during the manufacturing to provide real-time tracking of the manufacturing throughout the steps. An empirical analysis subsystem connects to different social media applications to determine sentiment of the manufactured product.

  • Patent number: 8527401
    Abstract: A computer system and method for processing a mortgage loan receives borrower, property, loan and underwriting data entered by a lender via a certifying company Internet web site. The system, which is operated by the certifying company, communicates with outside service provider systems to order and obtain products there from. The system is loaded with lender parameters for assessing loan risk. The system uses the entered data, outside service provider products and lender parameters to provide a loan assessment and a mortgage loan fulfillment product if the assessment is favorable. The mortgage loan fulfillment product includes a loan package, deed of trust, a promissory note, a title insurance policy and a loan fulfillment certification of the process compliance and data integrity.

  • Publication number: 20110186966
    Abstract: A gallium arsenide (GaAs) integrated circuit device is provided. The GaAs circuit device has a GaAs substrate with a copper contact layer for making electrical ground contact with a pad of a target device. Although copper is known to detrimentally affect GaAs devices, the copper contact layer is isolated from the GaAs substrate using a barrier layer. The barrier layer may be, for example, a layer of nickel vanadium (NiV). This nickel vanadium (NiV) barrier protects the gallium arsenide substrate from the diffusion effects of the copper contact layer. An organic solder preservative may coat the exposed copper to reduce oxidation effects. In some cases, a gold or copper seed layer may be deposited on the GaAs substrate prior to depositing the copper contact layer.

  • Publication number: 20070297106
    Abstract: A circuit and process is provided for protecting a device from the detrimental effects of electro-static discharge (ESD). The circuit includes an ESD breakdown device that is used to activate a current drawdown device. When a voltage exceeding the ESD breakdown device's breakdown voltage is applied, a signal is generated that causes the current drawdown device to pump current to ground. In this way, the effects of the ESD charge are substantially reduced. In one example, the ESD breakdown device is a reverse biased diode, and the current drawdown circuit includes a Darlington circuit. When an ESD surge causes the diode to breakdown, a signal is applied to the Darlington circuit, which pumps the ESD current safely to ground.

  • Publication number: 20030215655
    Abstract: Improved multi-layer coextruded blow-molded objects (such as fuel containers) having at least a barrier layer and a support layer are disclosed together with improved methods for preparing such objects. The barrier layer includes an amount of modified polyolefin having approximately the same density as the support layer, wherein the modified polyolefin is prepared by grafting an unsaturated carboxylic acid or a derivative thereof to the polyolefin, the modified polyolefin being added in an amount such that the gas-barrier layer sufficiently adheres to the adjacent layer and such that the gas barrier properties of the fabricated article are still adequate. The present invention also relates to modification of the rheology of base resins, such as PET (a preferred material for the barrier layer), so that they more closely match the rheology of high density polyethylene (a preferred material for the support layer).
