Chemical Approach to Spraying All Sides of a Complex Shape

A company seeks technology to spray waterborne substances — both suspensions and solutions — on all sides of an object, even the under sides, regardless of the attitude of the object or the direction from which the spray impinges. Nearuniform coating on all surfaces of the object is required. The technology should not affect the sprayed product negatively, and must work with current spraying equipment and liquid carriers.

Small, Mechanical Valve for Use With Propellant Gas

A valve technology is sought that can be used with a propellant- gas-based device aimed at the consumer goods industry. The valve will be used with a canister of propellant gas, in a handheld consumer device, and needs to be small, lightweight, and low-cost. The size should be in the millimeter to centimeter range, weigh less than 5 grams, require no priming, be air-actuated, allow a flow rate between 25 mL/sec and 90 mL/sec, and be manufactured from materials that meet European Union or FDA requirements.

Technologies to Protect Crop Plants From Pesticide Damage

A company seeks technologies or “safeners” that minimize the negative impact of pesticides on crops, such as physiological or cosmetic damage. The safener must have utility on a broad combination of crops, result in no inhibition effect or other performance consequences on the active ingredient, and have a minimum two-year shelf life under varying temperatures. Possible treatments include seed coating, pharma or cosmetic ingredients, or co-formulation with an existing product.

NASA Engineering Polymer Development Needs

There is increasing interest in lightweight and ultra-lightweight structural concepts and materials within NASA’s exploration mission and as part of efforts to develop “green” aeronautics options. Polymers and polymeric composites are important elements in design and construction of the nation’s future aircraft and spacecraft. Langley Research Center (LaRC) in particular has very active programs in development of advanced engineering polymers for use as structural components, as films or coatings, or for high-temperature or acoustic insulation.

Hydrogen Reclamation and Reutilization

John C. Stennis Space Center (SSC) provides rocket engine propulsion testing for NASA’s space programs. Since the development of the space shuttle, every Space Shuttle Main Engine (SSME) has undergone acceptance testing at SSC before going to Kennedy Space Center (KSC) for integration into the space shuttle. The SSME is a large cryogenic rocket engine that uses Liquid Hydrogen (LH2) as the fuel. As NASA moves to the new ARES V launch system, the main engines on the new vehicle, as well as the upper stage engine, are currently baselined to be cryogenic rocket engines that will also use LH2. The main rocket engines for the ARES V will be larger than the SSME, while the upper-stage engine will be approximately half that size. As a result, significant quantities of hydrogen will be required during the development, testing, and operation of these rocket engines.

Fast-Acting, Broad-Spectrum Disinfectant

A broad-spectrum pathogen disinfectant is sought that can kill Clostridium difficile (spore phase) in less than five minutes of contact time; preferably within a minute or less. A formulation that requires longer than a minute is also of interest if it can be formulated to provide ongoing protection. Ideally, the proposed solution will be “green”; that is, environmentally responsible in its formulation, manufacture, and effect on the environment after use. Metals such as copper, zinc, or silver ions cannot be part of the formulation. Respond to this TechNeed at: www.techbriefs.com/tn/200909d.html Email: nasatech@yet2.com Phone: 781-972-0600

Technology to Deposit Spray on the Underside of Crop Plants

A company seeks a technology to enable sprayable fungicides and a new additive that is compatible with current insecticides and fungicides. The technology must treat both sides of the leaves uniformly. Moreover, since spraying equipment represents a major time and cost investment from growers, the growers’ existing spraying practices must not be changed with new equipment or retrofits. The technology should not cause negative impact on the treatment product itself, or cause crop injury.
