A company seeks carbon nanotubes for conductive applications that, polymerized in bulk, can offer better conductivity than carbon materials in use today, and which are lighter in weight than current non-carbon conductors. The nanotubes should have conductivity approaching that of copper in...

A company is seeking a system or method for qualitative analysis of microorganisms that can then classify them according to their taxonomy, thus identifying them. The company needs to formulate a new, single, robust assay that classifies a microorganism if known, and if unknown by the assay, flags...

This technology mates load-bearing composite tubes to the metal fittings that support them, thus allowing composites to be used in applications currently requiring steel risers. The composites are geometrically pre-stressed during construction and mated to their metal fittings in a...

Most insulating applications block additional heat transfer by adding more insulation. This thin, flexible, aerogel-based thermal insulation is available in thicknesses from 0.25 to 1 mm, and achieves a thermal conductivity in the range of 15-20 milliWatts/meter-Kelvin (about...

An improved locking nut comprises (1) an internally threaded shell, partly resembling a conventional nut, that can be engaged by a wrench or other tool, and (2) an internally and externally threaded insert that engages the threads of the shell and a bolt. Whereas some prior locking nuts are plated over...

Reusable holders have been devised for evaluating high-temperature, plasma-resistant re-entry materials, especially fabrics. Typical material samples tested support thermal-protection-system damage repair requiring evaluation prior to re-entry into...
