"Cognitive Radio - An Adaptive Waveform with spectral Sharing Capability"
Chakravarthy (WSU Student-AFRL employee), Dr. A. Shaw (WSU Professor), J. Stephens
(AFRL), M. Temple (AFIT)
In the present system under which the FCC operates, different frequency bands are assigned to different services (radio, TV, phones, etc.). The phenomenal growth of radio communication services and other radio applications observed in recent years has increased spectral congestion. Spectral congestion occurs when multiple services transmit simultaneously using frequencies that are close together, which can result in poor performance. Even though the spectrum is fully allocated, only 5 to 10 percent is used at any given period. Cognitive Radio (CR) is a smart radio which has the knowledge of the environment and wisely utilizes the un-used spectrum minimizing spectral congestion. This invention presents an adaptive waveform applicable to CR technologies.
"Novel Thermally stable materials for structural, electronic and coating applications, especially aerospace and consumer products"
Dr. T. Dang (AFRL), M. Dalton (WSU student-SOCHE/AFRL), Dr. N. Venkatasubramanian (UDRI), Dr. J. Johnson (AFRL), Dr. W. Feld (WSU Professor)
Aerospace and consumer products increasingly require thermally stable polymeric materials for structural, electronics and coating applications. A series of thermally stable polymers containing trans-1,4-cyclohexane, 1,3-adamantane and 4,9-diamantane structural units as well as the triphenylphosphine oxide subunit have been synthesized. The polymers can be processed into tough, free standing films from organic solvents and exhibit high glass-transition-temperatures in the range of 192°-239° and thermooxidative stabilities (5% weight loss in air) in the range of 445°-490°. Preliminary results from a UV-visible spectroscopic study of dilute solutions of the polymers in chloroform showed absorption maxima in the 263-274 nm region and transparency to spectral radiation in the 300-800 nm range, indicating that these polymers could have potential applications for space thermal control coatings.
"Frequency-dependent circuit RFID with 3-D positioning"
Dr. B. Rigling
Passive radio frequency identification tags can be constructed using a simple
antenna and a circuit with a unique frequency-dependent response, in place
of an RF-powered integrated circuit with control logic. The unique frequency-dependence
of the circuit, which may simply be a feature of the antenna, conveys the
tags identification. Multiple frequency-dependent circuit RFID tags can
be simultaneously identified and located in 3-D space through use of antenna
arrays and sampling at multiple frequencies in order to provide spatial
"Novel Extrusion of Continuous Nanofibers in an Ultra-Viscous Medium"
Fibrous materials are utilized in every major industry in our society. As
such, advances in fiber fabrication techniques can represent significant
benefits across the technological spectrum. Due to the broad importance of
these materials, numerous efforts are being dedicated to the development
of nanofiber manufacturing processes. Nanofibrous polymer and ceramic materials
have been shown to possess a uniquelyadvantageous combination of ultra-high
surface area and structural integrity, making them attractive for many applications
such asfiltration, sensors, wound dressing, and tissue engineering. In addition,
nanofibers can produce enhanced strength, toughness, andvibrational damping
when used as a reinforcing element in composite materials, due to their ability
to achieve an unparalleled homogeneous dispersion while maintaining physical
separation between individual fibers. The most attractive and useful form
nanofiber material would be a continuous nanofilament. The availability of
such nanomaterial would have broad impacts in numerous fiber applications,
and could be processed into highly aligned yarn and cable, or utililized
in a woven textile material or continuous nanofiber-reinforced composite.
Despite significant research effort, there is no known method to produce
truly continuous, spoolable nanofiber. We have developed a highly novel wet-spinning
technique can allow the production of arbitrarily long lengths of nanofiber
in a controlled manner. Our approach involves injection of low viscosity
precursor material into an extremely viscous fluid flow, which is entirely
counter-intuitive to conventional fiber-spinning wisdom. This process operates
at low Reynolds numbers, and a fluid velocity mismatch between the injected
precursor and viscous media causes a diameter reduction effect that can be
as high as several orders of magnitude. The highly viscous medium stabilizes
the low viscosity precursor, maintaining fiber geometry while solidification
occurs. This process is entirely reproducible and predictable, due to the
laminar nature of the fluid flow. As such, it should allow the fabrication
of continuous fibers with true nanoscale cross sections, which could be collected
and spooled in order to allow further processing. The intellectual merit
of this proposal resides in the novelty of our fabrication process. It represents
a major advance in fiber wet-spinning technology, which is generally considered
to be physically incapable of generating stable liquid jets at submicron
length scales. It also presents a major advantage over the well known technique
of electrospinning, which is fundamentally stochastic in nature and cannot
produce a spoolable monofilament. The successful development of this technique
would represent a breakthrough in the area of manufacturing processes at
the nanoscale, and would significantly advance the state-of-the-art.
"Surface Nano-Coatings for Complex Solids"
Dr. Sharmila M. Mukhopadhyay
This R&D effort is to produce nano-meter thin functional coatings on complex solid structures such as, but not limited to, composite core materials, fibers, foam, fabric, consumer products, and bio-engineering devices. Two types of film have been fabricated, analyzed and tested to date: (1) chemically active films that can enhance the bonding between the surface and a matrix material, and (2) inert films that can make the surface moisture and degradation resistant. Some of these films may serve as precursors to growth of subsequent phases such as nanotubes and/or functionally gradient coatings, and the processes are being optimized.

absolute specificity, compact size and the potential for very low cost
detection with multiple fields of use.

"Diagnosis of water quality problems"
Dr. Allen Burton
The determination of whether water quality impairment exist and, if so, what their cause is can be problematic. Traditional methods used by the EPA are prone to error and misdiagnosis due to sampling and laboratory manipulation artifacts. The in situ test assay approach is rapidly growing in popularity because it allows for easier decision making with less uncertainty. It has been used successfully around the world and at many Superfund sites in the U.S. Aquatic organisms are exposed in simple chambers in streams, lakes and coastal areas to determine toxicity, bioaccumulation, and diagnosis of what is causing impairment.
"Water-Based Disease Intervention: Commercial Applications of Harmful
Dr. Carmichael's lab has developed three avenues of commercial use for his
work in blue-green algae. The lab analyzes water samples from all over
the world to determine if there are toxins in the water and how toxic those
waters might be. We grow toxins from isolated algae strains for use as
standards in scientific research by organizations such as the EPA and WHO.
Finally, we are beginning to produce test kits for use by utilities and
recreational personnel in monitoring harmful algae in their water systems.
