AGENCY: National Institute of Standards and Technology, Commerce.

ACTION: Notice of Inventions Available for Licensing.

-----------------------------------------------------------------------

SUMMARY: The inventions listed below are owned in whole or part by the 
U.S. Government, as represented by the Secretary of Commerce. The U.S. 
Government's interest in these inventions is available for licensing in 
accordance with 35 U.S.C. 207 and 37 CFR Part 404 to achieve 
expeditious commercialization of results of federally funded research 
and development.

FOR FURTHER INFORMATION CONTACT: Technical and licensing information on 
these inventions may be obtained by writing to: National Institute of 
Standards and Technology, Office of Technology Partnerships, Attn: Mary 
Clague, Building 222, Room A240, Gaithersburg, MD 20899. Information is 
also available via telephone: 301-975-4188, fax 301-975-3482, or e-
mail: mary.clague@nist.gov. Any request for information should include 
the NIST Docket number and title for the invention as indicated below.

SUPPLEMENTARY INFORMATION: NIST may enter into a Cooperative Research 
and Development Agreement (``CRADA'') with the licensee to perform 
further research on the inventions for purposes of commercialization. 
The inventions available for licensing are:
    [Nist Docket Number: 07-016].
    Title: Far Ultraviolet Dosimeter for Slow Neutron Detection.
    Abstract: This invention is jointly owned by the Department of 
Commerce and University of Maryland. The invention consists of a method 
for detecting slow neutrons by monitoring Lyman alpha radiation 
produced by the n(\3\He,t)p nuclear reaction induced by neutrons 
incident on a gas cell containing \3\He or a mixture of \3\He and 
\4\He.

    [Nist Docket Number: 07-017].
    Title: Compact Atomic Magnetometer and Gyroscope Based on a 
Diverging Laser Beam.
    Abstract: This invention is jointly owned by the Department of 
Commerce, the Defense Advanced Research Projects Agency, the University 
of California, Protiro, Inc., and Honeywell. A design for an atomic 
magnetometer that simultaneously achieves high sensitivity, simple 
fabrication and small size is described. This design is based on a 
diverging (or converging) beam of light (in a single spatial optical 
mode) that passes through an alkali atom vapor cell and that contains a 
distribution of beam propagation vectors. The existence of more than 
one propagation direction permits longitudinal optical pumping of the 
atomic system and simultaneous detection of the transverse atomic 
polarization. The design could be implemented with a micromachined 
alkali vapor cell and light from a single semiconductor laser. A small 
modification to the cell contents and excitation geometry allows for 
use as a gyroscope.

    [Nist Docket Number: 07-021].
    Title: Simple Matrix Method for Stray-Light Correction in Imaging 
Instruments.
    Abstract: This method uses stray light correction matrix derived 
from point spread functions (PSF) of an instrument. The correction of 
stray light errors is simply a matrix multiplication to the measured 
raw image. The correction is fast and can be used for correction of 
stray light errors in any types of measured images.

    [Nist Docket Number: 07-022]
    Title: Covalently Immobilized Fluorinated Carboxylic Acid 
Stationary Phases for Liquid Chromatography.
    Abstract: This invention relates to stationary phases for liquid 
chromatography, and more particularly, to fluorinated stationary phases 
for improved separation of constituents in the mobile phase and methods 
of making.

    [Nist Docket Number: 07-025].
    Title: Doubling the Service Life of Concrete--Reducing Diffusion 
Rates via Modification of the Hydrodynamic Friction of the Pore 
Solution.
    Abstract: The invention consists of a unique method to reduce 
diffusion rates in concrete by increasing the hydrodynamic friction on 
ionic species in the concrete pore solution. This novel approach 
involves changing the properties of the pore solution, rather than the 
microstructure. Conventionally, diffusion rates for concrete structures 
have been reduced by densifying the cement paste matrix component of 
the concrete via a reduction in water-to-cement ratio and/or the 
addition of fine pozzolanic materials such as silica fume and/or fly 
ash. Still, in every case, the pathways for diffusion are through the 
interconnected pore solution that saturates the porosity at all scales. 
By appropriately increasing the hydrodynamic friction, the diffusion 
rates of all ionic species (sulfates, chlorides, alkalis) can be 
reduced. Theory indicates that these diffusion rates will be inversely 
proportional to the solution's hydrodynamic friction coeffcient, so 
that doubling the hydrodynamic friction will reduce the diffusion 
coeffcients by a factor of two, which in turn should lead to a doubling 
of the service life for many degradation modes (sulfate attack, 
corrosion, etc.).

    [Nist Docket Number: 07-027].
    Title: Harvesting of Processed Carbon Nanotubes.
    Abstract: This invention is jointly owned by the Department of 
Commerce and the University of Maryland. The invention provides a cost-
effective, multi-step, scalable process employing grit shearing to 
remove the amorphous carbon shell and external catalyst contaminant 
from carbon nanotubes, separate bundles of nanotubes, and shorten the 
tubes.
