Abstract:
A new installation PERMEX for the investigation of ion-driven permeation through metals was designed and built. A metal membrane under investigation separates two high-vacuum chambers. In the implantation chamber, the membrane surface is irradiated with a monoenergetic deuterium ion beam with an incident energy in the interval of 100-3000 eV/D. The ion flux at the surface is in a range of 10(13)-2 x 10(14) D/cm2 s, the membrane temperature can be varied in the interval of 290-1050 K. The permeating deuterium flux from the outlet membrane surface to the volume of the second chamber (registration chamber) is measured by a quadrupole mass-analyzer. The outlet surface of the membrane can be cleaned by an argon ion beam. To approve the correct work of the setup a number of experiments were performed with Ni membranes. First results of experiments with tungsten membranes are presented.

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct microscopic...
