Analysis and theory of gas transport in microporous sol-gel derived ceramic membranes [PDF]
, 1995 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.

Hydrogen permeation through metals [PDF]
Vacuum, 1962 Abstract Hydrogen permeation rates have been measured for several metals of interest commonly used for vacuum envelopes. These include nickel, OFHC copper, Kovar, stainless steel, cold drawn steel, gas-free iron, Monel and Inconel. A continuous-flow technique was employed, a mass spectrometer tube serving as detector.
