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.

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.

The present disclosure relates to a dosimeter for measuring exposure to heat over time in combination with peak temperature indicators and reversible temperature indicators. The preferred temperature indicator tag is credit card sized and comprises four time-temperature dosimeters. Each dosimeter has a wick in contact with a separate reservoir containing a mix of a colored dye, a wax and an amorphous polymer to indicate a distinct temperature range when the mix melts. The wicks are preferably made of porous paper with a pore size around 8 microns to allow for proper capillary action along its length. An adhesive, except where each wick contacts its respective reservoir and at a vent, preferably seals each wick. The tag preferably has a plurality of peak temperature indicators where each indicator has a blend of a dye, a wax and a polymer for a temperature indication range. The tag also preferably has a plurality of reversible temperature sensors.

The Department of Energy (DOE) desires technologies that will extend the nations energy reserves with efficient, less costly, environmentally responsible electric energy and reduce our dependence on foreign oil. Integrated into the nations power grid system, Solid Oxide fuel cells (SOFCs) have the potential to achieve this goal with high reliability. SOFC energy is generated by combining fuel and oxidant (air) gases across an oxygen-ion-conducting ceramic. Interconnects must seal chambers from each other, but these seals can experience leakage. InnoSense LLC (ISL) will solve a leakage failure mode between the existing compliant glass layer and the metal interconnects. During the proposed project, ISL will develop mass production deposition technologies using appropriate metallorganic/organometallic sol-gel coatings to produce an SOFC Steel Seal (SOFSeal) a dense, adherent, thin (~1-2 m), 8 mol% yttrium stabilized zirconia (YSZ) coating for ferritic steels, with operating temperatures of 650850 C. These coatings will serve as bonding surfaces for compliant glasses used in SOFC interconnect seals. Commercial Applications and Other Benefits: ISLs SOFC Steel Seals will advance SOFCs with long lifetime reliability and the ability to be integrated into the nations power grid system. The SOFC target market includes replacement of peak demand fossil fuel burning electrical generation plants, which are responsible for an estimated 85% of the pollution output by the fossil fuel electrical generation industry. Markets include the co-generation market, backup power for buildings, hospitals, law enforcement facilities, homes, small remote facilities, auxiliary power units (APUs) for trucks, recreational vehicles, ships, and many aircraft.
