Impedance spectra of free standing polyaniline membranes were recorded in the symmetric and the asymmetric cell configuration. The polyaniline membranes were made by solution-casting of chemically polymerised polyaniline. The impedance spectra are di

Impedance spectra of electropolymerized polyaniline films were analysed by the theory of the impedance of macrohomogeneous porous electrodes. Specific ohmic and charge transfer resistivities were calculated, and their potential and pH dependence is d

Composites of polymer binders and conductive particles (e.g., graphite powder) are an interesting alternative bipolar plate material, since they are less expensive than pure graphite and less corrosion-sensitive than metals. By appropriate choice of

The conduct of Life Science experiments aboard the Shuttle Spacelab presents unaccustomed challenges to scientists. Not only is one confronted with the challenge of conducting an experiment in the unique microgravity environment of a orbiting spacecr

The KC-135 Reduced Gravity Facility at the Johnson Space Center is a useful support facility for conducting brief zero gravity life science experiments, as well as for validating hardware designs and experimental protocols for more extensive shuttle-

Although the gauge transformations of gravity involve four arbitrary functions, its «reasonable»operator transformations are distinguished by a single parameter. A one-dimensional set of «reasonable» gauges, connected by those transformations, ca

In close analogy to electrodynamics, we extend the well-known relations of Ward and Takahashi to gravity, which we describe by Gupta's formulation of Einstein's theory.
