A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

The Helium blanketing effect on LaNi5-xAlx and ZrCo alloy is researched. Hydrogen absorption and desorption change due to gaseous helium has been investigated by the serial experiments under different conditions. Helium reduces hydrogen absorption and desorption rate, but it would not change the ultimate quantities of hydrogen absorption and desorption. The surface electron spectrum of LaNi5-xAlx was examined by a multi-functional spectrometer. The examination shows that inert gas would not affect the electron state of the alloy surface and also the decomposition and absorption course of hydrogen molecule on the alloy surface. The research shows that Helium blanketing course is divided into two stages of "bulk flow" and "diffusion flow". After reaching the blanketing pressure the microcosmic course is molecule migration controlled by diffusion.
