Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

Cultured cell-based biosensors offer insight into the physiological action of the agent of interest, which is an advantage over other types of sensors. The development of cell-based biosensors that are field-portable would increase their utility in toxicology and environmental monitoring. One of the most significant issues hampering the development of field portable cell-based biosensors is the ...

DESCRIPTION (provided by applicant): Surgical excision of hard and soft tissues of the head and neck or high impact trauma can lead to lead to major tissue deficits. Reconstruction of the lower jaw typically involves bone, gingiva, and teeth. Current mandibular distraction devices are used in combination with reconstruction plates, but while the reconstruction plates take the contour of the jaw, t ...

Echo Technical and the Ellington Lab at the University of Texas at Austin previously developed a demonstration biosensor capable of using aptamer-based receptors (Biological Reconfigurable Interface Electronics For Classification and Analysis of Selected Elements, or BRIEFCASE). They proposed in Phase I to adapt a recently developed technology, proximity ligation assays, to a field-deployable dev ...

This 18 months STTR Phase II proposal is based on work completed under the STTR Phase I grant entitled “Multispectral Nanoantenna Infrared Sensors” (Contract No. N00178-04-C-3110). In this Phase II project, we propose the development of multispectral MWIR and LWIR nanoantennas and their integration with an ultra-high speed Cellular Visual Microprocessor operating at 10,000 frames per second. U ...

This STTR Phase II proposal is based on work completed under the STTR Phase I grant entitled "Focal Plane array processors with adaptive visual range and millimeter wave sensors" (Contract No. N00014-04-M-0212). In this Phase II project, we propose the development of two lines of ultra-high speed focal plane sensor and processor arrays equipped with (i) adaptive image sensors sensitive in the visu ...

As expected, the STTR Phase I investigation confirmed that the Digital Virtual Human (DVH) and Robonaut technologies can be merged, and that haptic and autostereoscopic technologies can be integrated in the robotic control systems, effectively and productively. This feasibility study verified and validated interactions of Robonaut with the DVH in operator response to and performance with haptic d ...

DESCRIPTION (provided by applicant): Neuro-inflammation is thought to be an important factor in age-dependent loss of neuron associated with Alzheimer's disease. We seek STTR funding to develop a unique transgenic rat that serves as a model for chronic neuro-inflammation and age-dependent loss of neurons. Presently, no other animal model offers specific patterns of neuro-inflammation, presence of ...

Nanomodified Carbon/Carbon Composites (NCCC) for intermediate temperature structures will be developed by combining selective nanoparticles in cyanate ester via optimum processing, followed by curing, carbonization and densification. These NCCC materials will exhibit improved thermo-oxidative stability beyond 700oF limit, involve lower cost NCCC materials, and replace titanium for structural comp ...

Ultra-high performance multi-function RF electronics are required by the United States Department of Defense to enable next generation radar and sensor networks in response to an increasingly diverse array of threats to our military and our homeland. An elegant potential solution is that of gallium nitride (GaN) RF electronics, which has shown great promise on currently available yet foreign subs ...
