The present invention relates to hydrophilic anti-fog coatings. In particular, the coatings use two types of nanoscale particles, colloidal silica and porous organosilicate micelles, in a polyurethane matrix. The invention is an anti-fog coating for optically clear substrates (polycarbonate, polyurethane, nylon, polyester and other clear plastics) without the need for a primer and glass or oxide substrates with an additional primer layer, comprising monosized colloidal silica nanoparticles and porous organosilicate micelles in a polyurethane matrix. The silica is preferably 1-5% by weight and the micelles are loaded at 0.1 to 10% volume percentage by volume. The polyurethane prepolymer is dissolved at 10-40% by weight in a mixture of tertiary amyl alcohol and diacetone alcohol to customize for dip, flow or spray coating processes.

The Department of Energy (DOE) seeks useful methods of generating intense beams of reaccelerated rare isotopes for the next-generation Facility for Rare Isotope Beams (FRIB), currently under construction at Michigan State University. Stopping high-energy, heavy-ion reaction products in fast-release solid catchers is an important method to be developed for realizing intense beams of short-lived isotopes of elemental or molecular species. Short-lived isotopes are expected to play a key role in unraveling the mysteries of nuclear physics, nuclear astrophysics, and fundamental interactions at low energies. General statement of how the problem is being addressed: This project will develop refractory, porous oxide monoliths as catchers, which retain open porosity after extended heating at high temperatures. The goal is to ensure that the oxide catcher retains open paths between grains for effusion of atoms or molecules from the catcher to the ion source in order to harvest unused rare isotope beams. Noble gases and reactive molecular species are targeted in these measurements. Simulations will be used as a predictive tool for the transient species of interest. What was done in Phase II: Phase II successfully established production methods to yttria-stabilized zirconia and hafnia disks (1–2 mm). The disks retained open, interconnected porosity (~50%) on the meso- to macro-scale upon heating to 1500 °C for up to 7-days and remained mechanically robust to handling. A very sensitive residual gas analyzer commissioned off-line showed excellent detection of 13CO molecules released from oxide nanopowder doped with 13C isotopic powder and on-line release of implanted 4He. What is planned for the Phase IIB project: More rigorous screening of candidate oxide catchers is planned in Phase IIB, to ensure sintering-free operation in isotope production conditions. On-line release studies will be conducted with light stable beams (4He, 13C) to downselect candidates for in-flight fragmentation reactions with 7Li and 18O to release 6He, and convert-and-release 16CO, both radioactive beams. Another goal is to adapt the porous oxide catcher technology for improved targetry in radioisotope production. Commercial applications and other benefits: Market need for these hot catcher materials exists in beam line facilities and FRIB for rare isotope production. Other potential markets include generation/delivery of radioisotopes to diagnostic and cancer therapy centers.

The micro-porous Polytetrafluoroethylene (PTFE) and glass separators currently used in lithium oxyhalide batteries (LOHBs) have limitations in performance, lifetime, safety, and costs. A new separator technology is needed to improve performance, provide more energy-efficient battery geometries, decrease manufacturing complexity, and lower cost by increasing operational lifetime. LOHB reserve cells must utilize materials that: (a) provide electrical isolation between electrodes, (b) maximize volumetric efficiency for electrolyte capacity, (c) optimize efficient electrolyte flow and distribution when the battery is activated, and (d) are suitable for a production environment. The targeted materials chemistry will be capable of integration into other battery systems for military, aerospace and commercial applications. In Phase I, InnoSense (ISL) will demonstrate proof-of-principle of flexible ceramic separators capable of operating in extreme corrosive environments. We will demonstrate MDA-relevant separator performance. We will work closely with industrial partners to ensure smooth integration with LOHBs. In Phase II, ISL will develop and rigorously-test separator prototype establishing scale-up pathways. ISL will have separators tested in oxyhalide batteries for battery performance by our industrial partner. Phase III efforts, in collaboration with our partners, will include further engineering of the separator integrated with LOHB, field level tests and evaluation leading to hardware qualification.

The Department of Energy (DOE) seeks useful methods of generating intense beams of reaccelerated rare isotopes for the next-generation Facility for Rare Isotope Beams (FRIB), currently under construction at Michigan State University. Stopping high-energy, heavy-ion reaction products in fast-release solid catchers is an important method to be developed for realizing intense beams of short-lived isotopes of elemental or molecular species. Short-lived isotopes are expected to play a key role in unraveling the mysteries of nuclear physics, nuclear astrophysics, and fundamental interactions at low energies. This project will develop refractory tungsten powders as catchers, which retain open porosity after extended heating at high temperatures. The goal is to ensure that the tungsten catcher retains open paths between grains for effusion of atoms or molecules from the catcher to the ion source in order to harvest unused rare isotope beams. Alkalis, noble gases and reactive molecular species are targeted in these measurements. Simulations will be used as a predictive tool for the transient species of interest. Phase I demonstrated the feasibility of grain growth suppression in candidate W powders. Offline, ultrahigh vacuum heating of candidate powders showed very low outgassing rates compatible with on-line characterization. Modeling refractory carbides and sulfides to optimize the selective release of specific elements as molecular sidebands was successfully completed. A very sensitive residual gas analyzer commissioned off-line showed excellent sensitivity to detect 13CO molecules released from alumina nanopowder doped with 13C isotopic powder. More rigorous screening of candidate W catchers is planned in Phase II, to ensure sintering-free operation in isotope production conditions. On-line release studies will be conducted with light beams (4He, 7Li, 13C and 18O) followed by heavier beams (136Xe and 120Sn). Predictive simulations of release characteristics will be validated through on-line release profiles. Commercial applications and other benefits: The immediate market need for these hot catcher materials is the DOE and installations like FRIB that have powerful and unique techniques for rare isotope production. Potential other markets include porous metals, metal foams in thermal management applications and medical applications such as diagnostics and cancer therapy.

General statement of how this problem is being addressed: During the proposed project, the company will develop polyurethane-silicone matrix foams with various additives be delivered to Fermilab for evaluation in Phase I, for the NuMI project. The foam composition and structure will be optimized for radiation resistance NoRaLFoam™ to withstand >1 MegaGray for 1-3 months and prevent release of friable or spalled materials from large bulky radioactive objects during the shipping and short term storage needed to transport to deposition at a sequestration site. What is to be done in Phase I: Polyurethane-silicone matrix foams will be formulated with additives to produce a composition and structure to block beta and gamma radiation, as well as have sufficient strength to hold spalling and other relatively small particles from escaping dueling transport and storage. Testing of the raw materials will be done to characterize microstructure, and foam properties. At least four (4) samples will be delivered to Fermilab for their evaluation by the end of Phase I. Commercial applications and other benefits: Radiation resistant foam can prevent release of radioactive material from mechanical spalling and abrasion of bulking items when shifting in containers during transport. This material can assist in reducing the cost and increase the safety of handling radioactive materials during ransport. Lower cost and more efficient radioactive material sequestration during transport will reduce the need for radioactive hazardous materials cleanup in the event of unwanted nuclear materials release. This material can be used for both civilian and military shipment of radioactive bulky items not only within the United States but worldwide, as well.

In-orbit or deep space-based plant growth systems are of interest to NASA as part of fundamental space research and for ensuring supply of fresh produce to the crew. These systems are part of enabling technologies for sustainable and long-term human spaceflight. Ethylene gas is a natural plant metabolite and phytohormone. In enclosed spaceship settings, ethylene build-up can be deleterious to plants. Thus, there is a need to monitor ethylene in real-time, sensitively, reversibly and effectively. Currently, state of the art technology is limited with portability and detection sensitivity issues. To close this technology gap, InnoSense LLC (ISL) will develop a solid state electrochemical sensor (Polymer Nanowire based ethylene Monitor (PNet-Mon)). To expedite this development, PNet-Mon will build on electronic hardware platform engineered by ISL previously. The innovation on this project will only be on ethylene sensing. This effort directly addresses a need expressed in NASA Technical Roadmap (TA 6).

Future manned spacecraft venturing into deep space will require sophisticated thermal control systems to protect against extreme environments ranging from direct illumination by solar radiation to complete darkness. To manage these extremes, heat exchangers composed of phase change materials, which can expand and contract without causing structural damage, will be essential. NASA is seeking non-toxic heat transfer fluids with transition temperatures between 8 and 12 (deg)C with heat of fusion >200 kJ/kg. Specifically, the fluids must have suitable thermal conductivity, high heat capacity, and low viscosity to enable flow with negligible volume expansion. Changes are also needed to reduce the existing heat transfer unit size and weight. InnoSense LLC (ISL) plans to develop new modified ionic liquid-based phase change materials heat exchangers. ISL, in collaboration the University of Nevada, will synthesize salt additives to modulate the operating temperatures, and the thermal and flow properties of the ionic liquid based eutectic phase change material with negligible volume change during phase change. In Phase I, ISL will formulate and test heat transfer formulations in a laboratory environment to demonstrate feasibility. During Phase II, ISL will scale-up synthesis and test fluid performance in a larger experimental apparatus and a wide range of working environments.
