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.

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.

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.

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.

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.

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.

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.

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.

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.

Board Design Test Vehicle

The Board Design Test Vehicle is a method for objective evaluation and qualification of supplier capabilities for the fabrication of multilayer printed circuit boards. It is used to analyze and assess technical capability and reliability of products that are provided by a supplier, and provides a mechanism for supplier improvement with validation. The design incorporates features that allow for analysis of variables data to determine actual process capabilities statistically and accurately, with a minimal amount of effort. Data can be plotted with distributions to determine process capability, revealing whether the data is “filtered” or cherry-picked, and can help evaluate the repeatability and consistency of processes. The ability to validate design rules is provided and matches supplier capabilities to actual designs.
