Firefly, in collaboration with Rochester Institute of Technology, proposes an STTR program for the development of a space solar cell having record efficiency exceeding 40% (AM0) by the introduction of nanowires within the active region of the current limiting sub-cell. The introduction of these nanoscale features will enable realization of an intermediate band solar cell (IBSC), while simultaneous ...

Computational tools that accurately predict the performance of electric propulsion devices are highly desirable by NASA and the broader electric propulsion community. Large investments in running the long duration test programs (> 20 kHrs) at NASA GRC can be reduced with computer models and allow more focus on exploring the NEXT ion thruster design for future space missions. The current state of e ...

In resource limited settings, rapid and accurate diagnosis of infections is critical for managing potential exposures to highly virulent pathogens,whether occurring from an act of bioterrorism or a natural event. This is especially important for hard to detect intracellular bacterial andalphavirus infections, that overlap symptomatically and often treated empirically due to a lack of reliable and ...

With the capacity and performance of FPGAs suitable for space borne applications continuously increasing, the design of FPGAs is becoming increasingly complex involving trading off or simultaneous optimization of space, speed, and power. RNET and ANL are proposing to develop software infrastructure that facilitates automatic performance tuning of FPGAs in terms of speed, power, and size. We introd ...

This proposal is in response to the Defense Health Agency 2017 Phase I SBIR topic 17B-005.The approach is the use of a membrane oxygen pump using newly developed nano-thickness membranes with all the layers less than 1 micron total.Nanometer thickness membranes enable more oxygen output per surface area at temperatures of 300-600 C than current state-of-the -art 600-800 C membranes that are 50-300 ...

The liberation of particles induced by rocket plume flow from spacecraft landing on unprepared regolith of the Moon, Mars, and other destinations poses high mission risks for robotic and human exploration activities. This process occurs in a combination of "extreme environments" that combine low gravity, little or no atmosphere, with rocket exhaust gas flow that is supersonic and partially rarefie ...

Traumatic injuries account for 30% of all life years lost in the US and is the leading cause of death for people under 46 years of age. Uncontrolled bleeding or hemorrhage constitute 30-40% of trauma related deaths and are considered to be a major cause o

We propose the development of a user-friendly software tool for estimating the electric field distributions within spacecraft enclosures based on the Power Balance (PwB) method and enhanced by a database of experimentally determined Absorption Cross-Sections (ACS) of common equipment, components and cables.The software will be built around an already developed PwB solver that determines the statis ...

Advances in structured heterogeneity together with nanomaterials tailoring has made it possible to create thermoelectrics using high temperature, polymer composites. While such thermoelectrics do not have the capability to approach the efficiency of top performing ceramic modules such as BiTe, they do provide two unique aspects of use in energy scavenging: the ability to cover large areas easily, ...

The landing surface damage and liberation of debris particles caused by rocket plume impingement flow during spacecraft propulsive landing on unprepared surfaces of Moon, Mars, and other celestial bodies poses a high risk for robotic and human exploration activities. Simply determining whether the plume induced loads exceed the bedrock bearing capacity threshold is not sufficient. An integrated m ...
