Abstract: Methods of fabricating uniform nanotubes are described in which nanotubes we re synthesized as sheaths over nanowire templates, such as using a chemical vap or deposition process. For example, single-crystalline zinc oxide (ZnO) nanowir es are utilized as templates over which gallium nitride (GaN) is epitaxially grown. The ZnO templates are then removed, such as by thermal reduction and evaporation. The completed single-crystalline GaN nanotubes preferably have inner diameters ranging from 30 nm to 200 nm, and wall thicknesses between 5 and 50 nm. Transmission electron microscopy studies show that the resultant nanotubes are single-crystalline with a wurtzite structure, and are oriented along the <001> direction. The present invention exemplifies single- crystalline nanotubes of materials with a non-layered crystal structure. Similar "epitaxial-casting" approaches could be used to produce arrays and single-crystalline nanotubes of other solid materials and semiconductors. Furthermore, the fabrication of multi-sheath nanotubes are described as well as nanotubes having multiple longitudinal segments.

Abstract: A catalytic hydrocracking process for the production of ultra low sulfur diesel wherein a hydrocarbonaceous feedstock is hydrocracked at elevated temperature and pressure to obtain conversion to diesel boiling range hydrocarbons. The resulting hydrocracking zone effluent is hydrogen stripped in a stripping zone maintained at essentially the same pressure as the hydrocracking zone to produce a first gaseous hydrocarbonaceous stream and a first liquid hydrocarbonaceous stream. The first gaseous hydrocarbonaceous stream containing diesel boiling range hydrocarbons is introduced into a desulfurization zone and subsequently partially condensed to produce a hydrogen-rich gaseous stream and a second liquid hydrocarbonaceous stream containing diesel boiling range hydrocarbons. The first liquid stream is separated to produce a third liquid hydrocarbonaceous stream containing diesel boiling range hydrocarbons which is also introduced into the desulfurization zone. An ultra low sulfur diesel product stream is recovered.

Title: Hepatitis c virus ns2/3 assay
Inventor: THIBEAULT DIANE
IPC: C07K16/10
Filed: 2006-03-16
Abstract: The present invention provides a novel assay for the detection of the NS2/3 cleavage products NS2 or NS3 in the presence of uncleaved NS2/3. In the present invention, following self-cleavage of NS2/3 to generate NS2 and NS3 cleavage products, the sample is incubated with a ligand specific for the recognition of NS2 or NS3 cleavage product in the presence of uncleaved NS2/3. There is provided a method for detecting a NS2/3 autocleavage product in a sample containing NS2/3 protease, the assay comprising: a) subjecting the sample to suitable conditions under which at least a portion of the NS2/3 protease is self-cleaved to yield cleaved NS2 and NS3 products;  b) incubating the NS2 and NS3 products with a ligand that can preferentially bind to one of either NS2 or NS3 product over NS2/3 under conditions suitable to afford binding of the ligand to NS2 or NS3; and c) detecting NS2- or NS3-bound ligand produced in step b), whereby the amount of bound ligand detected correlates with the NS2/3 autocleavage activity. The present method is also useful as an assay to screen candidate NS2/3 inhibitor compounds as potential treatment for HCV infection.  A  further aspect of the present invention concerns ligands selectively recognizing one of the NS2 cleavage product or the NS3 cleavage product with minimal cross-reactivity with the uncleaved NS2/3 and the other cleaved product. Specifically, the present invention provides antibodies that selectively recognize one of cleaved NS2 product or cleaved NS3 product with minimal cross-reactivity with the uncleaved NS2/3 and the other cleaved product.
