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.

Microencapsulation Technology

Unique Technologies A flexible, platform microencapsulation technology can be applied to actives from water soluble to water insoluble materials at the 20–35% range; loading levels of up to >50% have been achieved for some actives. The microcapsules protect the actives from environmental conditions, and can be designed to release their core materials in a controlled manner over a designated period of time or by a trigger (temperature, etc.). The capsules can be designed to have multiple cores that can either be contained throughout the inner core of the capsule or seeded in the shell (or both). These “seeded” microcapsules could be used in abuse-resistant pharmaceutical formulations, and could also be applied in a tableting process. The technology increases the bioavailability of pharmaceuticals difficult to formulate and can solubilize them.

Secure-Document Markup Software

Northrop-Grumman The Portion Marking Verification Tool (PMVT) software automates the process of regulatory document marking. This tool assists users in meeting the mandated requirements for portion marking in sensitive or classified documents. By utilizing PMVT, portion marking can be up to 200–400% faster than traditional review processes. PMVT handles all U.S. classification levels; SCI/SAP control channels and dissemination controls; guides reviewers through the classification process; allows reviewers to verify the suggested portion marking and make changes; and searches for words and complex expressions. The building of rule sets is flexible, and rule sets can be created to reflect government classification requirements. Email and other text repositories can be automatically scanned. PMVT is a software-only product integrated with the Microsoft Office environment.
