摘要:
A method for the solid-phase synthesis of combinatorial libraries on a one-dimensional support, such as a thread, is provided. The method involves the cyclic permutation of structural features along the thread, in such a way that different structural features are repeated at a characteristic fixed frequencies along the thread. The thread is processed so as to generate a signal proportional to the activity of the compounds in the library, and the thread is then assayed by being drawn through an appropriate detector. The resulting time-domain signal is processed by Fourier transformation. Spikes in the frequency domain of the processed signal indicate the frequency at which structural features that contribute to the activity were created on the thread.

Methods, systems, apparatus and machine readable media are disclosed to sequence nucleic acid. An example method includes subjecting a sequence of target nucleotide bases captured on a microtransponder to a plurality of sequencing reactions to build a sequence of labeled nucleotide bases that are complementary to and bound to the sequence of target nucleotide bases. The example method also includes identifying each labeled nucleotide base of the sequence of labeled nucleotide bases and each respective complementary target nucleotide base of the sequence of target nucleotide bases to which the labeled nucleotide base is bound after each sequencing reaction. In addition, each labeled nucleotide base of the sequence of labeled nucleotide bases and each respective complementary target nucleotide base of the sequence of target nucleotide bases to which the labeled nucleotide base is bound is associated with a microtransponder identification number.
摘要:
Nickel based catalyst structures are described herein that include a plurality of metal oxides formed as crystalline phases within the catalyst structures. Each metal oxide of a catalyst structure includes nickel and/or aluminum, where one or more metal oxides includes a nickel aluminum oxide, and the one or more nickel aluminum oxides is greater than 50% by weight of the crystalline phases within the catalyst structure. The catalyst structures further have specific surface areas of at least 13 m 2 /g. Mixed nickel aluminates such as the spinel phase, NiAl 2 O 4 , and NiAl 10 O 16 are shown to have a high stability in reforming reactions. The catalyst structures are resistant to high concentrations of sulfur and are effective in reforming operations for converting methane and other light hydrocarbons to hydrogen and one or more other components. For example, the catalyst structures are effective in coal and biomass gasification systems for the forming and cleanup of synthetic gas.

摘要:
A test device comprises first and second indicia portions. The first indicia portion is configured to indicate the presence or absence of at least one medical condition based on identification of at least one biological entity in the biological sample. The second indicia portion is configured to display all or part of a composite code when the first indicia portion provides an indication of the presence of the medical condition, the code being substantially unique to the test device. The test device includes a printed circuit board and a portion of the composite code corresponds to a serial number of the printed circuit board.
