Measurement of Oxygen with Sub-PPM

A company is searching for an innovative technology for the measurement of oxygen with sub-ppm resolution. They are seeking a continuous method of measurement or those with cycle times measured in seconds, the ability to measure within a flammable gas such as hydrogen, and a non-consumable device with a long lifetime (greater than 5 years). Oxygen shock should not damage the sensor or require special treatment to recover it. Respond to this TechNeed at: Email: nasatech@yet2.com Phone: 781-972-0600

High-Efficiency, Flexible, High-Stability Solar Cells

Nanotechnology-based hybrid nanocrystal inorganic thinfilm photovoltaics combine the best features of solar cells constructed from bulk thin-film silicon and from polymer solar cells. The colloidal nanocrystal (NC) cell technology offered here allows the production of air-stable solar cells processed using solution phase methods. The technology simplifies fabrication under ambient conditions, thus expanding the range of flexible or conformal substrates that can be used.

Environmentally Friendly Non-Stick Perfluoroalkyls

The C6 perfluoroalkyl formulation overcomes the environmental issues inherent in other perfluoroalkyl tails, and imparts non-stick properties and resistance to oil, grease, solvents, or water that are similar to C8 fluoroalkyl tails. Chemicals containing perfluoroalkyl tails are used for stain, water, oil, and grease resistance, and for their surfactant and non-stick properties. In a commercially available formulation used on a cellulose substrate, it resists oil and water penetration under either aggressive (hot polar fats) or non-aggressive conditions (ambient temperatures, non-polar oils), and is approved for paper treatment where the paper may be in contact with food.

NASA’s Science Mission Directorate’s Sensor, Detectors, and Instrument Technology Needs

The Science Mission Directorate (SMD) engages the Nation’s science community, sponsors scientific research, and develops and deploys satellites and probes in collaboration with NASA’s partners around the world to answer fundamental questions requiring the view from and into space. The National Research Council is an advisor to SMD and conducts decadal surveys to define science priorities in its discipline areas for the next decade. SMD seeks to understand the origins, evolution, and destiny of the universe and to understand the nature of the phenomena that shape it. SMD also seeks to understand:

Substance with High Affinity for Large Antigen Molecules

A company seeks a process of making high-affinity antibodies (or other substances) that can bind rapidly to antigens of large molecular sizes, such as proteins. Achieving high-affinity binding is important for expanding detection limits and achieving diagnostics in short amounts of time. This need is for a highly sensitive, high-affinity antibody or process of designing and making a substance that works as well as antibodies in having a high affinity to a given analyte, and a high speed of binding.

Self-Contained Therapeutic Thermal Wrap

A company seeks technology leading to a flexible, adhesive thermal patch or wrap for sore muscles that provides lasting warmth for 8 to 12 hours or more. The technology should not involve a chemical active in contact with the skin. The heating effect should be able to be activated anywhere, without the use of plugs or wires. It should provide perceivable relief from discomfort within about one minute, and fit comfortably over wrists or knees without being overly obtrusive.

Paracellular Drug Delivery Through Baker’s Yeast Microcapsules

Yeast has the ability to reversibly open up the junctions between cells to aid drug delivery. By micro-encapsulating active ingredients inside the yeast cells, this technology enhances paracellular movement of active ingredients in mucus-rich areas such as buccal, oral, nasal, vaginal, anal, and others. Application could be by means of powder, tablet, capsule, chewable tablet, chewing gum, melting film strip, spray, cream, or gel. Yeast offers an alternative to chitosan as a permeation enhancer and mucoadhesive mechanism.
