During the last few decades, one of the most prevalent issues associated with the performance of aerospace composite materials has revolved around low interlaminar mechanical properties. The innovations described in this work outline a number of new and improved techniques for...

Electron-ionized atom trapping technology is widely used in mass spectrometry and atomic clocks. The complexity of the trapping configuration operating in an ultra-high vacuum system is driven by demands for ultimate sensitivity, performance, and fundamental...

The speed of thin-film transistors (TFTs) relates directly to their gate length, which must be kept as short as possible to lower electron transport time between electrodes, and improve its high-frequency response characteristics. Since current density is...

This software reads MLS Level 1 products — the Earth Observing System (EOS) Microwave Limb Sounder (MLS) calibrated measurements of microwave radiance products and operational meteorological data — and produces a set of estimates of atmospheric temperature and composition. The software...

The metal layers at mesospheric altitudes are excellent tracers of neutral atmosphere dynamics, and have been used since the 1960s to study the chemistry and dynamics of the mesosphere. Ablation from meteors is believed to be the chief source of metals such as Na, Mg, K, Fe, and Ca in the middle...

Agents that could be used in chemical and biological warfare tend to disperse widely in the air when released. Quickly collecting a concentrated sample of these agents is critical to detecting them before they reach harmful dose levels in the air. Also, methods of detection such as by polymerase...

NASA's Langley Research Center has developed an optical method for detecting displacements and strains at ultra-high temperatures during thermo-mechanical testing. This innovation will provide displacement and strain measurements in...
