Protecting Anodized Aluminum in a Highly Alkaline Environment

A company seeks to protect the surface of an aluminum product when exposed to the harsh alkaline environment inside a dishwasher. The product currently has a hard-anodized surface to protect against abrasion. The company seeks to avoid an exterior coating that can be abraded away. Preferably, the surface would be made impervious by adding to the anodized coating, changing the material of the coating, or changing the chemistry by which it’s made.

Composite Materials — Partnership Opportunities

Organic matrix composite materials have the potential for a significant mass reduction compared to metallic materials for aircraft and spacecraft, and have been a NASA focus for many years. The major technology drivers for these applications include large-scale composites manufacturing, composite damage tolerance and detection, and primary structure durability. Successful composite technologies will demonstrate concepts with reduced weight and cost with no loss in performance when compared to technologies for metallic concepts.

Smart and Intelligent Sensors

Rocket engine testing is the primary mission for Stennis Space Center. Test stand facilities include the B-1/B-2 complex built for the Apollo Program, which is now used to test the RS-68 engine. A number of smaller test stands are available for testing components and lower thrust rocket engines. A-3 is a new test stand under construction that will have the capability to simulate high-altitude conditions. For each test article, the customer expects to receive highquality measurements to support their engine design, validation, and certification requirements. Making these measurements requires hundreds or thousands of sensors.

Low-Friction Surface for Ready-to-Use Catheter

A company seeks a low-friction surface for ready-to-use intermittent catheters for both men and women, with the goal of achieving insertion and retraction without causing any trauma or perception of trauma. The low-friction surface must operate during insertion, while the catheter is in place, and during removal. Balance between kink-resistance and flexibility is important, and the ability to insert the catheter without touching it would be ideal. It must offer 3-5 years of shelf life at ambient temperatures, and use biocompatible materlals.

One-Handed Ergonomic Approach to Pliers/Cutters

A company seeks a new generation of precise, ergonomic pliers that virtually eliminates the effort that causes hand fatigue. Ideally, it would require the exertion of zero force to cut through Romex, strapping, or staples. The tool must provide one-handed operation and conform to a variety of grips a worker may use. It is preferable that the device use mechanical advantage rather than power, although self-contained power assist is acceptable. A battery pack or compressed air connection will not work.

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.

Triclosan Replacement

A company seeks a replacement for triclosan, a popular anti-microbial agent used in household products. The replacement requires thermal stability to withstand manufacturing temperatures (such as polymer melt temperatures during molding), UV stability, and compatibility with anionic detergents. It should also be environmentally friendly, sustainable, broad-spectrum, and cause no color change or odor in the product to which it is applied.
