Abstract:DESCRIPTION (provided by applicant): Ovarian cancer is a highly lethal gynecologic cancer with an estimated 21,860 new cases and approximately 13,850 deaths in the USA per year. A large majority of the patients, cancer reoccurs after initial treatment and manifest resistance to conventional and… more
Abstract:At NOVATIO Engineering, our solution to this problem is practical, novel, proven at a smaller scale and now demonstrated at the 3 kW size range: conversion of a commercial lightweight gasoline generator to operate with diesel fuel or JP-8 in spark ignition mode. Prior to this Phase I SBIR effort,… more
Abstract:Acumentrics is developing a new reformer system capable of significantly increasing efficiency while reducing components, component cost, and system complexity. This proposal applies that system to biofuel as well as other fuels as the technology is scaled up from small units in order to develop an… more
Abstract:Abstract Persistent injury to the liver can cause chronic inflammation and dysregulated deposition of extracellular matrix (ECM), leading to accumulation of fibrotic scar tissue and eventually cirrhosis. While fibrosis is a normal wound healing response, in excess, it can further injure tissue and… more
Abstract:Aerosol particles are known to affect the global climate through cloud formation. Globally, it is believed that ~50% of cloud condensation nuclei (CCN) originate from atmospheric new particle formation and growth. Sulfuric acid vapor plays a key role in new particle formation, although detailed… more
Abstract:Nitrous oxide, N2O, is one of the most important greenhouse and ozone-depleting gases in the atmosphere, with levels that are increasing in part because of soil emissions and agricultural practices. New, improved instruments are needed to quantify the sources and sinks of nitrous oxide and to… more
Abstract:We plan to propose an LED-assisted ignition technique for lean-burn internal combustion engines. It has been known for decades that lean fuel/air mixture is difficult to ignite than the stoichiometric mixture. The proposed technology is based on enhancing chemical reactivity of fuel-air mixtures by… more
Abstract:Methane is the second most important atmospheric greenhouse gas after CO2 yet its global sources and sinks are still inadequately characterized. Monitoring the isotopic composition of atmospheric methane is one of the most promising approaches to closing the methane budget. Detailed process… more
Abstract:Aerosol particles affect the radiative balance of the earth directly, by scattering and absorbing solar and terrestrial radiation, and indirectly, by acting as cloud condensation nuclei. It is now recognized that the atmospheric loading of aerosols can exert an influence on the … more
Abstract:There is a need for extremely lightweight low power instrumentation for real-time measurement of isotopic variants of carbon dioxide (CO2) in ambient air, suitable for use on un-manned aerial vehicles, to allow better quantification of sources and sinks of this major greenhouse gas in remote areas… more
Abstract:Greenhouse gas (GHG) emissions to the atmosphere are primary drivers of global climate change and hence there is a crucial need to quantify their sources and sinks. A general technique to constrain source and sink strengths is the analysis of the relative proportions of isotopic variants of GHG's. … more
Abstract:ABSTRACT: We and our team partner Emu Solutions, a University of Notre Dame spin-off, will implement and ultimately deliver ISiS_PFA (Image Stabilization in Silicon_PFA), an electronics hardware implementation of our recently-invented Polynomial Factor Analysis (PFA) jitter mitigation algorithm. … more
Abstract:NAVAIR PMAs are motivated by substantial maintenance cost savings to switch aircraft paints from matte to glossy. Yet NAVAIR must confidently weigh these major cost savings against possibly serious survivability penalties from sun glints. To definitively answer these survivability trades, we propose… 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.
