This Month in NASA History

This year, as NASA celebrates its 50th anniversary, we’ll be highlighting technology innovations and important moments in NASA history, leading to our special 50th Anniversary Issue in October. This Month in NASA History: On June 18, 1983, Sally Ride became the first American woman in space aboard the Space Shuttle Challenger. Learn more about these events at .

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.

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.

Using Piezoelectric Devices To Transmit Power Through Walls

It would not be necessary to make holes in walls for wires. A method denoted wireless acoustic- electric feedthrough (WAEF) has been conceived for transmitting power and/or data signals through walls or other solid objects made of a variety of elastic materials that could be electrically conductive or nonconductive. WAEF would make it unnecessary to use wires, optical fibers, tubes, or other discrete wall-penetrating signal-transmitting components, thereby eliminating the potential for structural weakening or leakage at such penetrations. Avoidance of such penetrations could be essential in some applications in which maintenance of pressure, vacuum, or chemical or biological isolation is required.
