Specific alloys, in particular Ni-based alloys, that can be biaxially textured, with a well-developed, single component texture are disclosed. These alloys have a significantly reduced Curie point, which is very desirable from the point of view of superconductivity applications. The biaxially textured alloy substrates also possess greatly enhanced mechanical properties (yield strength, ultimate tensile strength) which are essential for most applications, in particular, superconductors. A method is disclosed for producing complex multicomponent alloys which have the ideal physical properties for specific applications, such as lattice parameter, degree of magnetism and mechanical strength, and which cannot be fabricated in textured form. In addition, a method for making ultra thin biaxially textured substrates with complex compositions is disclosed.

Various embodiments provide a method and apparatus for processing incoming packets in an efficient manner. A service ID bitmap indicating available services associated with the user is established. The available services are grouped into service set. Common service set having common set of rules is determined. A user associated with common service set and incoming traffic is identified. The incoming traffic is processed according to the common set of rules indicated by the service ID bitmap. The efficient use of Ternary Content Addressable Memory (TCAM) results in faster search result, lower power consumption and chip footprint among others.

In one embodiment, a method includes receiving label data that indicates all interface labels that belong to each path ID of multiple path IDs associated with corresponding multiple paths between provider edge nodes in a Multi-Protocol Label Switching (MPLS) network. Each interface label is associated with a network interface on a node in the MPLS network. Based on the label data, an untested list that holds data that indicates all unique interface labels is generated. A tested interface selected from the untested list is scheduled for testing. After scheduling, the interface label of the tested interface is removed from the untested list. It is determined whether the untested list still includes data for at least one interface label. If not, then a test of the MPLS network is completed without testing every path end to end, thus conserving network resources.

A superconducting article includes a substrate having a biaxially textured surface. A biaxially textured buffer layer, which can be a cap layer, is supported by the substrate. The buffer layer includes a double perovskite of the formula A2B′B″O6, where A is rare earth or alkaline earth metal and B′ and B″ are different transition metal cations. A biaxially textured superconductor layer is deposited so as to be supported by the buffer layer. A method of making a superconducting article is also disclosed.

A crystalline article includes a single-crystal ceramic fiber, tape or ribbon. The fiber, tape or ribbon has at least one crystallographic facet along its length, which is generally at least one meter long. In the case of sapphire, the facets are R-plane, M-plane, C-plane or A-plane facets. Epitaxial articles, including superconducting articles, can be formed on the fiber, tape or ribbon.

The present disclosure provides for systems and methods for producing carbon nanotubes. More particularly, the present disclosure provides for improved systems and methods for producing single wall carbon nanotubes (SWNTs) by chemical vapor deposition (CVD) using a carbon source in the presence of a catalyst. In exemplary embodiments, the present disclosure provides for improved systems and methods for producing single wall carbon nanotubes (SWNTs) by chemical vapor deposition (CVD) using carbon monoxide (CO) disproportionation in the presence of a catalyst composition on a catalyst support material. In one embodiment, the present disclosure provides for systems and methods for producing single wall carbon nanotubes (SWNTs) by chemical vapor deposition (CVD) using carbon monoxide (CO) disproportionation with CO pressure from about 0.20 atm to about 1.0 atm in the presence of a cobalt/molybdenum catalyst composition on a magnesium oxide catalyst support.

Novel articles and methods to fabricate same with self-assembled nanodots and/or nanorods of a single or multicomponent material within another single or multicomponent material for use in electrical, electronic, magnetic, electromagnetic and electrooptical devices is disclosed. Self-assembled nanodots and/or nanorods are ordered arrays wherein ordering occurs due to strain minimization during growth of the materials. A simple method to accomplish this when depositing in-situ films is also disclosed. Device applications of resulting materials are in areas of superconductivity, photovoltaics, ferroelectrics, magnetoresistance, high density storage, solid state lighting, non-volatile memory, photoluminescence, thermoelectrics and in quantum dot lasers.
