Reflective Aerosol

This technology need is for an aerosol with properties that enable it to be easily launched using a pulsed jet fogger. It also must have reflectivity or other optical properties, and must be safe for human cutaneous and pulmonary contact. The aerosol should have optical properties that can be manipulated using laser light or other light sources to produce large-scale images and other visual effects. The aerosol would be used to create a large image that is visible from multiple vantage points by “painting” the aerosol from within or without in such a manner that a three-dimensional object is emulated.

Laser Drilling of Ceramic Composites to Form Smooth-Walled Holes

Attempts to mechanically drill high-temperature ceramic components can doom them to failure. Even laser drilling can compromise the surface oxidation layer that protects the composite part in high- temperature service.

Molecular Vaccine for Prophylaxis and Treatment of Listeriosis

Biomedical Center in Moscow has developed a peptide formulation that induces activation and proliferation of the cytotoxic lymphocyte’s (CTL) clones and enables them to recognize and selectively kill Listeria infected cells. As the lifetime of CTL clones is 3 to 7 years or more the formulation could be used for both prophylaxis and treatment. The developer is looking for support/collaboration to implement the following three stages: promoting the peptide preparation as a veterinarian vaccine; promoting the peptide preparation as human vaccine; and promoting the peptide preparation in Europe and other markets.

Rapid DC Magnetron Sputtering

DC magnetron sputtering provides a very durable and stable coating that has many high-energy laser (HEL) and industrial applications, especially in producing coatings for high-reflectivity (HR) mirrors and anti-reflection (AR) coated windows. However, the DC magnetron sputtering deposition process is extremely slow. This slow deposition results in long coating run times that translate into increased coating cost. An organization wants to reduce magnetron sputtering deposition times from 17 hours to 2 or 3 hours, while meeting current coating performance requirements. Coatings must meet MIL-C- 48497A environmental requirements.

Low VOC Binder/Resin System

Technology is required to reduce volatile organic compounds (VOCs) in binder/resins while maintaining or enhancing existing product properties. Potential solutions could include the addition of a compound or additive that reduces VOC demand, a new crosslinking system for polymers to enhance molecular network formation, or another technical solution that eliminates the existing issues with the low VOC resins currently available, such as poor appearance and high viscosity during drying (as typically encountered in a water borne approach), or slow drying and high application viscosity (as typically encountered in high-solids paints).

Diagnostic Pattern Recognition Using Mid-IR Spectroscopy

By applying mid-infrared spectroscopy to bodily fluids, this suite of technologies offers the potential for quick, accurate, and inexpensive diagnostic support for a variety of diseases in humans or animals. Every disease or condition results in quantitative imbalances in the “normally occurring” molecules of the body — raised glucose or cholesterol, for example. Pathogens like bacteria and viruses contribute their own molecular loads as well as destabilizing the body’s “homeostasis;” its usual stable and healthy condition. A spectrographic “snapshot” of sample fluids from blood serum, lymph, and saliva can be matched to the unique spectroscopic pattern of known conditions and diseases. Pattern recognition can then result in a quick diagnosis.

Precision Feedback-Controlled Laser Drilling for Fluid Flow Apertures

This technology provides a method of laserdrilling any component under the control of real-time feedback to provide for predictable, calibrated fluid flow through one or an array of holes formed in the component. The technique can improve flow control through a machined part by an order of magnitude or more over conventional open-loop laser drilling technologies, increasing the predicted lifetime of component parts. The method can be applied to any component or device that requires controlled flow of any fluid.
