Environmentally Friendly Non-Stick Perfluoroalkyls

The C6 perfluoroalkyl formulation overcomes the environmental issues inherent in other perfluoroalkyl tails, and imparts non-stick properties and resistance to oil, grease, solvents, or water that are similar to C8 fluoroalkyl tails. Chemicals containing perfluoroalkyl tails are used for stain, water, oil, and grease resistance, and for their surfactant and non-stick properties. In a commercially available formulation used on a cellulose substrate, it resists oil and water penetration under either aggressive (hot polar fats) or non-aggressive conditions (ambient temperatures, non-polar oils), and is approved for paper treatment where the paper may be in contact with food.

High-Efficiency, Flexible, High-Stability Solar Cells

Nanotechnology-based hybrid nanocrystal inorganic thinfilm photovoltaics combine the best features of solar cells constructed from bulk thin-film silicon and from polymer solar cells. The colloidal nanocrystal (NC) cell technology offered here allows the production of air-stable solar cells processed using solution phase methods. The technology simplifies fabrication under ambient conditions, thus expanding the range of flexible or conformal substrates that can be used.

Self-Contained Therapeutic Thermal Wrap

A company seeks technology leading to a flexible, adhesive thermal patch or wrap for sore muscles that provides lasting warmth for 8 to 12 hours or more. The technology should not involve a chemical active in contact with the skin. The heating effect should be able to be activated anywhere, without the use of plugs or wires. It should provide perceivable relief from discomfort within about one minute, and fit comfortably over wrists or knees without being overly obtrusive.

Substance with High Affinity for Large Antigen Molecules

A company seeks a process of making high-affinity antibodies (or other substances) that can bind rapidly to antigens of large molecular sizes, such as proteins. Achieving high-affinity binding is important for expanding detection limits and achieving diagnostics in short amounts of time. This need is for a highly sensitive, high-affinity antibody or process of designing and making a substance that works as well as antibodies in having a high affinity to a given analyte, and a high speed of binding.

High-Performance CIGS Solar Cell Saves Resources

AIST has developed a thin-film technology that can reduce the consumption of raw selenium below one-tenth of the conventional standard when manufacturing non-silicon-based copper-indium- gallium- selenide (CIGS) thin-film solar cells. The technology uses radio-frequency- cracked selenium radicals instead of conventional vaporized selenium, enhancing the conversion efficiency of a solar cell, and results in cells of reproducible quality from run to run. Additionally, the technology uses a black metal electrode and a light-absorbing layer containing zinc oxide. This brings about a great advancement for mass production of high-performance CIGS modules.

Paracellular Drug Delivery Through Baker’s Yeast Microcapsules

Yeast has the ability to reversibly open up the junctions between cells to aid drug delivery. By micro-encapsulating active ingredients inside the yeast cells, this technology enhances paracellular movement of active ingredients in mucus-rich areas such as buccal, oral, nasal, vaginal, anal, and others. Application could be by means of powder, tablet, capsule, chewable tablet, chewing gum, melting film strip, spray, cream, or gel. Yeast offers an alternative to chitosan as a permeation enhancer and mucoadhesive mechanism.
