A novel method of fabricating carbon nanotube (CNT) reinforced polymer matrix composites is proposed. It includes growing super-aligned carbon nanotube arrays on a flat substrate, using NCSU proprietary shear pressing method to compress the grown arrays into a layer of densely packed, highly aligned CNTs inclined at an angle of several degrees to the substrate, separating the produced CNT sheet fr ...

This NASA Phase I STTR effort will establish the feasibility of developing a compact broadband near to mid-IR programmable optical comb for use in laser based remote sensing and communications. The comb generator will use a waveguide-based optical parametric gain block technology that can have ultra wideband (>250nm) operation with very high gain (>25dB) in a very compact footprint. This approach ...

AdvR, Inc. proposes the development of an efficient process for fabricating ridge waveguides in magnesium-doped lithium niobate (MgO:LN). The effort will include, but will not be limited to, fabricating ridge waveguides in periodically poled MgO:LN for highly efficient, single-pass, quasi phase-matched frequency conversion. Ridge waveguides in MgO:LN will significantly improve the performance (p ...

Abstract There is a valid scientific data paradigm where no loss of data can be tolerated. However, transmission of raw data requires unacceptable bandwidth and storage resources such that the net data received is uncomfortably low. Lossless data compression can be used to preserve all data with no information loss and also help meet bandwidth and storage constraints. The current Universal Sou ...

A great deal of research has been done on thin film Carbon Nanotube Transistors. Single Walled Carbon Nanotubes (SWNTs) have exceptional electrical properties, High speed circuits require high carrier mobility, and individual SWNTs have a carrier mobility of up to 120,000 cm2/Vs and can be doped n and p-type. Enriched semiconducting SWNTs (s-SWNTs), narrowed down to individual chiralities provid ...

DESCRIPTION (provided by applicant): Freezing of Gait (FOG) effects the majority of the approximately one million individuals who have Parkinson's disease nationwide and causes a cessation of movement that patients describe as feeling as if their feet are glued to the ground . FOG most often occurs in the mature stages of Parkinson's disease and results in a loss of balance and severe falls. Thes ...

DESCRIPTION (provided by applicant): The NF-?B family of transcription factors plays a central role in the regulation of lymphocyte proliferation, differentiation and survival. Aberrant constitutive activation of NF-?B has been identified in many different aggressive lymphoid malignancies in humans and contributes to lymphomagenesis and chemotherapeutic resistance by driving the expression of NF-? ...

DESCRIPTION (provided by applicant): In patients with chronic kidney disease (CKD), phosphate retention may contribute to progression of renal failure and is a major factor in the development of secondary hyperparathyroidism and vascular calcification. Progression of injury is causally associated with risk of mortality that is estimated 10 to 30 times higher for CKD patients undergoing dialysis th ...

DESCRIPTION (provided by applicant): This STTR project proposes to develop a novel optical scalpel for ultra-precise ophthalmic laser surgery. Segmentation and removal of epiretinal membranes during vitreoretinal surgery is currently performed mechanically with both blunt and sharp dissection, which causes collateral damage to healthy retinal tissue. Conventional fiber-based surgical laser micropr ...

DESCRIPTION (provided by applicant): Ischemia-reperfusion injury (IRI) occurs in organs when circulation is interrupted, causing ischemia, and then ischemic tissue is reperfused. This leads to a series of biologic consequences, resulting in edema and inflammation. IRI is a significant problem in organ transplantation, because IRI is the major cause of primary graft failure and organ dysfunction af ...
