Flame-Resistant Fastening Between Two Fabrics

A flame-resistant fastening between two fabrics is sought, and must be simple to operate. The connection should resist frequent flexing, and must have a breaking strength of 120 kilogram-force. If folded cross-wise, it must withstand 40 kilogram- force, and may need to stand up to direct flame for 50 seconds or more. The resulting connection between the fabrics must be aesthetically pleasing. When subjected to flame, the connection cannot emit any toxic fumes.

New Coating Chemistries with Excellent Outdoor Durability

A multinational advanced materials company is seeking wet coating technologies that show excellent weathering and durability. The coatings need to be applied to glass substrates. The coating needs to have excellent outdoor durability in excess of 10 years, have a hardness of at least 2H, and be optically transparent (<1.0% haze might be acceptable). As well as the coatings being suitable for application in a solution, they also need to be able to be used as a binder or cross-linking component of coatings.

Technologies to Enhance Moisture, Vapor Transmission

A company is looking for environmentally inert methods to change the moisture management properties of conventional apparel textiles. The moisture management effect changes the way in which water vapor, moisture, and other liquids move through textiles, and can be activated via pH, temperature, or rising moisture levels. The solution would be applied in the presence of a surfactant. The effect does not have to be durable because the solution permits reapplication.

Connection of Two Rubber-Impregnated Cloth Surfaces

A way is sought to allow consumers to connect and disconnect two rubber-impregnated cloth surfaces in a consistent manner that is easy to assemble and disassemble. The cloth surfaces are in close proximity; the length of the connection will be about two meters. The connection must exhibit longterm durability and be able to withstand in-use forces. The joining method should have similar ease-of-assembly as a zipper and be silent.

Quantifying Breast-Feeding Volume

A method is sought to provide a real-time quantitative measure of the volume of milk consumed as a baby breast-feeds. The solution must be safe, environmentally sound, non-invasive, retail for under $50, and should not interfere with mother- newborn bonding. It should be compatible with home use and relatively small in size, and should show results in a specific standard or some calibrated multi-point scale.

Environmentally Friendly Solvents

A specialty chemical company is seeking innovative green, renewable raw materials, products, and processes for replacement of existing non-environmentally friendly solvents while not compromising the performance or significantly increasing the costs. The solutions should be biodegradable, low/non- VOC, low toxicity, and economically competitive. Sources for renewable raw material solutions may include glycerol, sugars, furfural, succinic acid, and bioethanol.

Remote Cloud-Height and Visibility Sensing

A small, low-power automatic sensor technology is needed to determine the cloud coverage, cloud ceiling height between 3,000 to 20,000 feet, and visibility up to at least five miles. These measurements must be provided in day and night conditions. The devices need to be small for easy placement at remote sites (not necessarily near cities or airports) and must operate autonomously.
