With 5 million Americans compromised by the ravages of this disabling disease, CHF is the leading cause of Medicare hospital admissions. The economic burden exceeds 40… more
Abstract:This Small Business Innovation Research Phase I project proposes high specific strength composite sandwich panels using a new form of manufacturing, tailored for Amorphous Metal Honeycomb (AMH) cores. Previously it was impossible to form these alloys as honeycombs since they do not behave like… more
Abstract:ABSTRACT: This proposal proposes to develop an agile methodology to identify bad actor parts to proactively address part performance. The methodology with algorithms and models will be developed by merging ideas from different areas of Science and Engineering. Some of the algorithms and models to… more
Abstract:We propose to demonstrate the feasibility of using time domain terahertz measurements to locate, identify and image defects and material variations within advanced composite materials used in missile radomes. We will investigate the time and frequency domain transmission properties of radome… more
Abstract:The current practice of training canines for explosives detection utilizing actual explosives requires qualified personnel that are trained to handle
explosive materials making the training both manpower-intensive and costly. The expense is further exacerbated by the need to handle and dispose… more
Abstract:Due to their vast diversity and as-yet uncultivated status, detecting, characterizing and quantifying microorganisms in natural settings are of grand challenge, and understanding the mechanistic linkages between microbial diversity and ecosystem functioning and their feedback responses to human… more
Abstract:The interactions among different microbial populations in a community play critical roles in determining ecosystem functioning but very little is known about the network interactions in a microbial community due to the lack of appropriate experimental data and computational analytic tools.… more
Abstract:This Small Business Innovation Research (SBIR) Phase II project will design, build, test, and validate a fully operational prototype disk drive incorporating a commutational ramp load actuator (CRLA). The CRLA is a unique and transformative actuator for disk drives that provides significant… more
Abstract:DESCRIPTION (provided by applicant): Age-related macular degeneration (AMD) is a sight-threatening disease which represents the leading cause of blindness and visual impairment in elderly individuals in developed countries. Recently, laser and photodynamic therapies with limited clinical benefit… more
Abstract:DESCRIPTION (provided by applicant): This Small Business Innovation project aims to develop an innovative eye drop formulation for the treatment of glaucoma and ocular hypertension. Charlesson has acquired from Danube Pharmaceuticals MSH-1001, a new smallmolecule compound (previously known as… more
Abstract:DESCRIPTION (provided by applicant): The objective of this proposal is to finalize development of CLT-005, a novel small molecule inhibitor of Stat3, through the performance of studies required for the submission of an investigative new drug application with the US Food and Drug Administration… more
Abstract:DESCRIPTION (provided by applicant): Most patients with solid tumors die of tumor recurrence at the same site or metastasis of the tumor to distal sites. An intermediate step in both recurrence and metastasis is a stage called tumor dormancy, where the cancer cells are suppressed by a normal… more
Abstract:DESCRIPTION (provided by applicant): The primary objective of this proposal is to develop and commercialize a safe and more effective therapy for the treatment of Crohn's Disease, an inflammatory bowel disease. Crohn's Disease is a chronic inflammatory disorder of the gastrointestinal… more
Abstract:Active defects negatively impact the performance of IRFPAs by increasing noise at various levels up to, and including, catastrophic degradation. Evidence indicates that"killer defects"are related to the interaction of open core screw dislocations with impurities that remain after… more
Abstract:For HgCdTe infrared focal plane arrays fabricated on Si substrates, a model has recently been proposed to account for the disparity between the density of failed pixels and the density of dislocations that are present in the HgCdTe junction region. The model distinguishes between active and inactive… more
Abstract:Silicon wafers oriented on (112) are the preferred substrates for deposition of mercury cadmium telluride layers by molecular beam epitaxy. Surface defects introduced during polishing of the wafers degrade the quality of the epitaxy and the performance of infrared detectors fabricated within these… more
Abstract:The proposed research and development activities will determine the scientific, technical, and commercial feasibility of the use of solvent-free liquid
polymer-grafted surface wipes as novel materials that more efficiently removes low volatility chemical agent contamination from porous and… more
Abstract:DESCRIPTION (provided by applicant): Progressive disseminated histoplasmosis is a common and life-threatening fungal infection among patients with HIV/AIDS in the United States and Latin America. Incidence rates in HIV/AIDS can be gt20%, with mortality rates gt30% in resource-limited countries… more
Abstract:This project optimizes haptic system design parameters and more thoroughly evaluates the impact of a vibratory haptic system for prosthetics. Objectives include: (1) building a hardware and software test bed for non-invasive voluntary control of a prosthetic hand with vibratory haptic feedback, (2)… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
