摘要:
The invention provides a process for hydrocyanation, comprising: contacting 2-pentenenitrile with hydrogen cyanide at a temperature in the range of about 0° C. to about 150° C. in the presence of at least one Lewis acid promoter and a catalyst precursor composition, wherein the catalyst precursor composition comprises a zero-valent nickel and at least one bidentate phosphite ligand selected from a member of the group represented by Formula I and Formula II, in which all like reference characters have the same meaning, except as further explicitly limited: wherein R1 and R5 are independently selected from the group consisting of C1 to C5 hydrocarbyl; and R2, R3, R4, R6, R7 and R8 are independently selected from the group consisting of H and C1 to C4 hydrocarbyl.
摘要:

摘要:
An apparatus and system, may include a thermal interface material comprised of an array of carbon nanotubes and a buffer layer disposed between the thermal interface material and one of a die or a heat spreader. In some embodiments the carbon nanotubes may be formed above a buffer layer formed above a surface of the heat spreader.
摘要:
A method and system for providing address matching consistent with the invention includes comparing the address against a plurality of address records in a database, wherein the database comprises at least one of the following: a delivery point database (505) and an enhanced delivery point database (705). In addition, the method and system include providing output data indicating whether the address has been matched to at least one of the plurality of address records in the database.
摘要:
Systems and methods are provided for determining secondary address information. In one implementation, a method is provided that uses a data processing apparatus. According to the method, a code word is created for a business name and a building default extended delivery code. A data table is searched using the code word and secondary address information is revealed when a match is found between the code word and data stored in the data table.
摘要:
A method of dispensing aerosol spray products by removing aerosol spray valve, connecting an adapter down into the mounting cup assembly which becomes an adaptive platform for inserting at least one type valve actuator that is connected by flexible tubing to an external remote medium for dispensing liquid aerosol products at correct mixtures irregardless of angle of application of the remote medium because aerosol container can remain in an upright position while applying with the remote medium at any angle required, even upside down.
摘要:
Diamond and non-diamond composite film may be exposed to oxygen plasma to gasify the non-diamond forms of carbon, leaving porosity in the resulting structure. In some cases, highly desirable dielectric materials may be formed with high dielectric constants and good mechanical strength.
摘要:
Systems and methods for determining default address information for mail items having incorrect or incomplete delivery addresses, where the default address information may be used to generate barcodes, which may be applied to the mail items to facilitate automated sorting of the mail items to carrier routes.
