Self-consistent Mean Field theory in weakly ionized media [PDF]
We present a self-consistent mean field theory of the dynamo in 3D and turbulent diffusion in 2D in weakly ionized gas. We find that in 3D, the backreaction does not alter the beta effect while it suppresses the alpha effect when the strength of a mean ...

Analysis and theory of gas transport in microporous sol-gel derived ceramic membranes [PDF]
Sol-gel modification of mesoporous alumina membranes is a very successful technique to improve gas separation performance. Due to the formed microporous top layer, the membranes show activated transport and molecular sieve-like separation factors.
