Is there any work going on binary mass diffusivity of helium-4 in various material?

08 August 2017 1 10K Report

I am in search of the helium escape rate from specific container/balloon material, i.e. Rubber Latex, maylar foil, metal container,etc. at Temperature ranging 240 - 320K

Alexander Sebedash

Please find in the attachment some papers about diffusion of helium. As I know helium practically do not penetrate metals.
