Estimation of permeation probability in plasma driven permeation
Fusion Engineering and Design, 1998Abstract Hydrogen permeation experiments were carried out with different thickness of Ni membranes; 20, 50 and 200 μm, pre-conditioned for the same surface conditions. Hydrogen plasma was created by ECR heating and plasma driven permeation (PDP) through the Ni membrane of 523 K was investigated.

A REVIEW OF PERMEATION TUBES AND PERMEATORS
Separation and Purification Methods, 2000In this review, the basic principles underlying the design and application of permeation tubes and permeators are discussed. The fundamental theory is cast in terms of Fick's Laws and Henry's law. The various types of polymer materials and permeation tube devices are then discussed, with a view toward the final application of the devices.

Abstract A new fully automated gas permeation system was designed and constructed for the measurement of low permeation rates and permeate compositions. The advantage of the new design over similar systems is that it is practically leak-free and it allows for the measurement of permeation rates of 1 × 10 −8 cm 3 /s or lower with extreme accuracy ...

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1987
A permeation routing algorithm is proposed which decides the detailed routes on a new layout model. The permeation router attains a higher density by using the expanded routing region as well as the conventional one simultaneously. This routing algorithm consists of two phases.

, 1968 All micro-organisms possess a barrier which effectively preserves the integrity of the organism and limits the entrance and exit of solutes. It is now generally agreed that this barrier, which has been termed the ‘osmotic barrier’, resides in the lipid-protein cytoplasmic membrane.

Permeation and Permeation Barrier
2016Because of their small sizes in molecular and atomic forms, hydrogen isotopes easily dissolve in a solid material and permeate through it. The permeation through a container material is a critical issue against safe confinement of tritium. On the other hand, it is common to employ a permeation technique for the separation of hydrogen isotopes from ...
