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.

Delivery System for Controlled Release of Actives

A technology is sought that will enable delivery of active cleaning compositions triggered at a specific time/place by a large range of conditions. The solution must be environmentally safe, must function at a pH range between seven and 11 and temperatures between 5 and 80°C, be compatible for use with chemicals in liquid or solid form, and be suitable for use in a mass-market consumer product. It must not inhibit homogenous mixing of the active material into solutions or onto substrates after dispensing.

Natural Preservatives for Beverages

Organic antimicrobial chemistries are needed to act as natural preservatives for a variety of beverages. They must be safe, stable, colorless, odorless, and tasteless at the concentration necessary to act as a preservative, and be effective at low concentrations (below 1%). They must extend the overall lifetime of the beverage and the nature of the beverage must not change.

Thin-Film Solar Cell Technologies

Thin-film technologies are sought for dye-sensitized solar cells that are flexible and printable on a plastic substrate; amorphous silicon/microcrystalline silicon tandem solar cells and textured TCO glass; and copper-indium- gallium-selenide solar cells that are flexible and printable on a plastic or stainless steel substrate. Also needed is a quasi-solid-state electrolyte (for outdoor reliability and stability) and a sintering technology to deposit TiO2 paste on flexible substrates at temperatures under 150°C.
