Maintain Food Crispiness from Freezer Storage to Microwave Preparation

Methods are sought to replicate the texture of crunchy food in a convenience food stored in a freezer and prepared in a microwave oven. All ingredient-based solutions must be GRAS (generally recognized as safe) for human consumption. Cost must be within 1 to 2 cents per pound for the final product, and cooking time, once out of the box, must be complete in 4 to 6 minutes. Storage time for the packaged food should be 18 months in a home freezer.

Freshness Indicator for Consumer Packaging

A technology is sought that indicates that a product packed into a rigid metal container has not been tampered with and/or degraded over time. The solution must incorporate a method of communicating this information to the packager, retailer, or consumer. After packaging, and depending on the product, the container may be subjected to a thermal treatment, to a maximum of 130°C for an hour for some canned foods, or a 90°C pasteurization treatment for some beverages.

High-Birefringence Optical Material

A high-birefringence optical material suitable for implementation in optical systems is sought. This material has several qualities of interest beyond high birefringence: high hardness, making it amenable to standard polishing and manufacturing processes; low CTE (coefficient of thermal expansion); low CTRI (coefficient of thermal refractive index); low absorption at 1.55 micrometers; and reasonable bulk density. A material is sought that can be processed and handled using standard techniques.

Orthobiologics to Treat Spine-Related Diseases

This organization seeks new orthobiologic technologies that stimulate bone growth, provide a growth scaffolding, and promote bone healing through osteoinduction (bone formation is actively induced) and osteoconduction (where a scaffold facilitates bone repair passively) in spinal fusion repairs. They are also seeking FDA-approved elastic materials with strength and stiffness close to cortical bone.

Frizzy Hair Control

Materials and compounded products are sought that, when deposited on hair from a leave-on or rinse-off conditioner, will control frizzy hair and leave a positive feel to the hair. Any solution must be non-toxic and safe for use by children. It should neither produce environmental difficulties in its use or manufacture, nor affect the stability of the formulated product to which it is added. Additionally, it should not interfere with other benefits delivered. Possible materials include associative or cross-linked polymers, silicones, and non-polar oils.

Eliminate Color Fading in Washable Cotton Garments

Cotton garments, especially dark-colored garments, lose their initial color through repeated washings and exposure to sunlight. Needed is a new technology or technology system that will give cotton garments improved color fastness, but which does not depend just on using a more expensive dye with higher fastness. Such a treatment could take place during one of the several stages in the manufacture of cotton garments.
