NASA desires new phase change systems to regulate heat transfer among components within a CubeSat small spacecraft. The temperature variation within the small spacecraft often leads to large temperature spikes that may be detrimental to onboard unit components. Temperatures can often range from -40 �C to +80 �C. InnoSense LLC (ISL) will develop an ionic liquid-based heat transfer fluid for use within the CubeSat. Our method will be to control the functional groups attached to an ionic liquid to tune the melting point and reduce electrical conductivity of the material. The proposed technology will be tailored for use with a variety of different components within the CubeSat. In Phase I, ISL proposes to synthesize a functionalized ionic liquid and test its thermal properties. The proposed material is expected to have high thermal conductivity, high heat storage density, and melting point with range of component operation. During Phase II and follow-on phases, the proposed technology will be refined, optimized, and scaled to larger size production. The proposed materials will also be tested in various environments. Packaging methods will be investigated and the final product will be integrated into working CubeSats with the assistance of a CubeSat design company.

ABSTRACT: InnoSense LLC (ISL), in this project, will demonstrate the feasibility of an ITO repair method that can be applied under ambient conditions. Upon reviewing the state-of-the-art techniques, ISL focused on developing a repairing matrix that promotes strong adhesion of ITO-compatible material system to repair irregular scratches and nicks that can occur during routine missions. Using electrohydrodynamic spray deposition, followed by thermal curing, ISL will make sure that the damages are filled seamlessly with matching optical and shielding capabilities. In Phase I, ISL will demonstrate feasibility by applying ITO alternatives to scratched ITO-coated polycarbonate coupons to restore their optical and electrical properties. In Phase II, ISL will improve the synthesis of the material matrix, produce and deliver 1 kg of material and demonstrate the scratch repair of ITO coatings (scratches representing different depths and widths) without scattering or loss of continuity, guided by testing to both MIL-STD-810E and MIL-C-48497 protocols. During the transition to Phase III, ISL will work with USAF and prime contractors to establish flight and other field testing requirements needed to certify the coatings. Testing will include extensive surface and volume resistivity, and EMI shielding and actual flight tests to determine product performance in field environments. BENEFIT: Military and commercial applications overlap for ITO repair. Applications include the dissipation of and shielding from incident energy for aircraft windows and canopies, display technologies, opto-electronic devices, cell phone displays, computer touch screens, and solar panels. All of the technologies require continuous transparent conductive coatings in order to function properly. Each industry has its own requirements and specifications for both the coating and repair.

eSpin Technologies will develop a new advanced liquid electrolyte separator for Li ion batteries which has the potential of having a significantly higher volumetric efficiency for electrolyte storage capacity and kinetics to distribute electrolyte flow within nanoporous channel efficiently. This new separator will be based on an advanced nanofiber construct with increased porosity and smaller pore size. The separator material will be a non-corroding and protective against toxicity of electrolyte. This advanced separator will also demonstrate excellent thermal stability over a range of temperature and strength to withstand battery manufacturing operation. The gain in volumetric efficiency results from high surface area nanofiber material and the large number of small pores within the structure which not only stores electrolyte but aids in improved electrolyte distribution with speed. Advanced separators lower weight and thinner construct will result in lower flow and electrical resistance, thereby allowing electrolyte to penetrate and provide increased ionic conductivity and higher rate capability.

The Department of Energy is seeking development of technologies to extract power from coal while expanding environmental protection and confronting global climate change. Protective Coatings are needed for Solid Oxide Fuel Cell SOFC) Balance-of-Plant BOP) component stainless steels used in cathode air management at 700 C to 900 C and humidified air evolve chromium Cr) vapor species that poison SOFC cathodes, degrading performance. Low-cost coatings for hot BOP components are desired to reduce/eliminate Cr species evolution. Evaluation will include performance Cr species evolution) under high-temperature, high humidity and production/processing cost at high volume. The company will develop low-cost stainless steel alloy coatings for cathode-side hot piping and/or heat exchangers. We will develop cost effective slurry/spray coatings for interior surfaces piping with joint welds, baffles, etc.) and irregular geometries, having Cr-volatility mitigation as effective as industrial pack cementation and vapor coatings. We will develop a BOP components sol-gel seal paint or ink based on YSZ and/or alumina. BOP sealant will be a paint or ink that can be applied by a low-cost dipping operation, and fired to produce a dense, adherent, thin ~1-2 m), 8 mol% YSZ coating paint or ink for ferritic stainless steels, from low cost alumina-forming austenitic alloy AFA) stainless steels to higher cost Allegheny Ludlum 441. These coatings will serve as barrier surfaces for BOP components. This BOP sealant will improve SOFCs by providing long lifetime reliability and the ability to be integrated into the nations power grid system. The sealant can be applied to heat exchangers, heat pumps, heat pipes, chemical reactors. The improved SOFCs will have application in several markets: 1) the co-generation market, 2) backup power for buildings, hospitals, law enforcement facilities, homes, and small remote facilities, and 3) auxiliary power units APUs) for trucks, recreational vehicles, ships, and aircraft.
