At low frequency (ca. 〈10.sup.-2 Hz), capacitors made up of this so-called tube super-dielectric material were found to have extreme dielectric constants, greater than 1 billion. The same capacitors also registered unprecedented energy densities, nearly 400 J/cm.sup.3, better than that observed (〈250 J/cm.sup.3) for the same type of anodized titania filled with an aqueous solution of NaNO.sub.3, and about an order of magnitude better than commercial supercapacitors. Sufficient data were collected to propose a correlation relating dielectric thickness and salt concentration to overall energy density.

    Description: The broadband electromagnetic pulse (EMP) transient measurement preemphasis filter ( Filter ) was developed to improve the signal-to-noise ratio in the high-frequency portion of single-pass EMP transient response measurements. Improvements of 12 dB and more have been observed at frequencies above 80 MHz with no loss of dynamic range in frequency components below that point.

    Description: NASA's Planetary Geosciences Programs (the Planetary Geology and Geophysics and the Planetary Material and Geochemistry Programs) provide support and an organizational framework for scientific research on solid bodies of the solar system. These research and analysis programs support scientific research aimed at increasing our understanding of the physical, chemical, and dynamic nature of the solid bodies of the solar system: the Moon, the terrestrial planets, the satellites of the outer planets, the rings, the asteroids, and the comets. This research is conducted using a variety of methods: laboratory experiments, theoretical approaches, data analysis, and Earth analog techniques. Through research supported by these programs, we are expanding our understanding of the origin and evolution of the solar system. This document is intended to provide an overview of the more significant scientific findings and discoveries made this year by scientists supported by the Planetary Geosciences Program. To a large degree, these results and discoveries are the measure of success of the programs.
