The present invention discloses an alumina carrier for a silver catalyst, a process for preparing the alumina carrier, a silver catalyst made from the alumina carrier, and a use of the silver catalyst in the production of ethylene oxide by the oxidization of ethylene. The alumina carrier comprises alumina and promoters, as well as titanium silicate molecular sieve(s); and therefore, has an improved catalytic activity.

A method of producing reduced corrosion interconnect structures and structures thereby formed. A method of producing microelectronic interconnects having reduced corrosion begins with a damascene structure having a first dielectric and a first interconnect. A metal oxide layer is deposited selectively to metal or nonselective over the damascene structure and then thermally treated. The treatment converts the metal oxide over the first dielectric to a metal silicate while the metal oxide over the first interconnect remains as a self-aligned protective layer. When a subsequent dielectric stack is formed and patterned, the protective layer acts as an etch stop, oxidation barrier and ion bombardment protector. The protective layer is then removed from the patterned opening and a second interconnect formed. In a preferred embodiment the metal oxide is a manganese oxide and the metal silicate is a MnSiCOH, the interconnects are substantially copper and the dielectric contains ultra low-k.
摘要:
An apparatus comprising a data framer configured to frame an external protocol extension message for transmission, the external protocol extension message comprising a header that indicates an external protocol extension and at least one type-length-value (TLV) comprising a type field, a length field, and a value field, wherein a format of the TLV is specified by a specific organization, and wherein the value field comprises information related to protocol functions external to the network. Also included is an apparatus comprising at least one component configured to implement a method comprising compiling an external protocol extension message comprising a plurality of TLVs and a header that indicates an external protocol extension, and transmitting the external protocol message.
摘要:
A method and a system is disclosed for providing quality of service (QoS)-driven channel access within a basic service set (BSS) in a wireless local area network (WLAN). A contention control (CC) frame is sent from a point coordinator (PC) of the BSS during a contention-free period (CFP) of a superframe that includes the contention-free period (CFP) and a contention period (CP). The CC frame contains information relating to at least one of a priority limit for a next centralized contention interval (CCI), a length of the next CCI, a permission probability associated with the next CCI and information relating to a reservation request (RR) frame successfully received by the PC in a previous CCI. A non-colliding RR frame is then received at the PC in the CCI following the CC frame. The received RR frame is sent from a non-PC station in the BSS when at least one centralized contention opportunity (CCO) is available during the CCI after the CC frame. The RR frame indicates that the non-PC station sending the RR frame has at least one buffered data frame for transmission.
