Anti-Reflective Coating for Films

Able to withstand abrasion even with steel wool, these antireflective coating formulations for display applications offer high durability and reflectivity that ranges from 1.2% down to 0.5%. Reducing ambient light reflectance significantly improves image clarity on LCD and PDP displays and rearprojection televisions, especially in daylight or outdoor conditions. Lenses and other optical equipment may be additional applications. This DuPont technology is a single-pass roll-toroll (microgravure) coating process. Because of its refractive index and thickness, light reflected by the underlying substrate is out of phase with light reflected from the front surface. The two phases cancel each other out, dramatically reducing reflectance and improving image clarity. All the formulations offer exceptional adhesion to the substrate, a neutral color, and exceptional durability. The single applied coating spontaneously forms two layers to improve scratch resistance, adhesion, and improved optical benefits.

Page-Rendering Software for eBooks and Manufacturers

Rapidly evolving eBook technology promises to deliver books, catalogs, newspapers, or magazines anywhere electronically on compact, easy-to-carry readers. eBooks face challenges that physical books do not: file security during transmission, speed of transmission, and the risk of piracy. The ReadAllOver™ system is a proprietary dual solution of compressed file format and rendering software engineered for the next generation of eBooks. ReadAllOver is based on proprietary halftone algorithms, printing to the screen in much the same way as presently is done with ink and paper. The algorithms offer improved edge detail allowing the entire page, images, and typography to be processed at once. The result is a more print-like look and feel.

Large Aperture Inflatable/Deployable Antennas and Their Role in NASA’s Vision for Space Exploration and Earth Science

As NASA evolves its vision for space exploration and Earth science, greater demands are placed on advanced communications and sensing systems to allow for higher data-rate communications from the Moon, Mars, and beyond, as well as for more precise Earth and planetary remote sensing activities. Taking into consideration the cost of launching hardware into space (about $20K per kg), as well as the fairings’ volume limitations, there is need for novel antenna technology concepts to circumvent these limitations, without jeopardizing the desired capabilities. To address this scenario, NASA is investigating the development of large aperture, inflatable/deployable antenna (IDA) technologies as a viable option to fulfill the aforementioned requirements. Attainment of these requirements demands overcoming a series of critical challenges as discussed below.

Converting High-Molecular-Weight Polymer Emulsions Into Dry Form

A company that supplies chemicals, including inverse emulsions that consist of a very high- molecular-weight, water-soluble polymer dispersed in a continuous oil phase, is seeking technologies that can convert these emulsions to powdered form without losing any of the polymer properties. Known technologies include spray-drying and precipitation. Precipitation processes are based upon the water and oil being soluble in some polar solvents, while the high-molecular- weight polymer is insoluble in these solvents.

Anti-Itch Non-Steroidal

A company is seeking technology (synthetic actives, natural actives, delivery systems) to eliminate itch for a variety of indications for over-the-counter applications; specifically, actives and/or delivery systems that will relieve itching. The technology should eliminate itching for a significant period of time (i.e. several hours, minimum). Alternatively, immediate relief (within 60 seconds) would be of interest. Any formulation is acceptable, but oral delivery or physical barrier approaches will not be considered. Respond to this TechNeed at: Email: nasatech@yet2.com Phone: 781-972-0600

Password Protection System Requires No Special Hardware

The High-Security Password System takes the place of strong passwords on digital devices and online services, yet is easy to remember and quick to enter for most individuals. This system places images in a two- or three-dimensional matrix to generate the equivalent of a ten-digit number. The security of the system can be increased by cells in the matrix, also consisting of a number of cells.

Catalytic Filters for Outdoor Power Equipment

NoxFox™ Catalytic Filters reduce harmful emissions from engine exhaust with performance comparable to existing catalytic converters. High-surface-area ceramic nanofibers hold nanoparticles of platinum, palladium, rhodium, and other catalysts, so that NoxFox catalytic filters are comparatively lightweight and robust. Patented, catalyzed ceramic nanofibers (nCATfibers™) provide high surface area for maximal contact and minimal exhaust resistance. Engine makers can use NoxFox catalytic filters do the job not possible by engine tuning and deliver a highly “green” product. In addition, the product’s unique structure results in a 50% weight reduction over existing honeycomb catalytic converters.
