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.

Sustainable Processes for Green Polymer Production

Technologies leading to sustainable and green production of polymers are sought. Candidate technologies should fit recently developed definitions for green chemistries. Chemistries that produce safe chemicals, that use safer solvents and auxiliaries, and/or that produce chemicals designed for degradation are preferable. Byproducts of the process should either not be hazardous, or easy and economical to be rendered harmless for people and the environment.

Chemical Analysis without Reagents

A portfolio of technologies applies mid-infrared spectroscopy to the analysis of fluids. Any fluid can be analyzed, including blood, serum, and other biological fluids. Tests are non-destructive. The techniques require no reagents or other chemicals, and thus there are no chemicals to store or dispose of. The spectroscopic signatures obtained from the samples can be used to aid the diagnosis of disease, among other applications, because molecular signatures are unique. The technique has a high sensitivity to the conformation of the molecule: shape, folding, symmetry, and its state.

Selective Elimination of Nitrogen Oxides from Exhaust Gases

The Environment Purification Materials team of AIST’s Synergy Materials Research Center (Japan) has successfully developed and tested significantly improved electrochemical reactors for the selective elimination of nitrogen oxides (NOx) in a range of industrial exhaust gases containing oxygen. The inventors have engineered and refined the electrochemical cell anode, cathode, and solid oxide electrolyte to possess nano- and micro-structure control. This fundamental improvement enables very highly efficient operation at low levels of electrical power and current required for NOx decomposition in the presence of excess oxygen.

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).

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.

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.
