• #### Fast resolution change in neutral helium atom microscopy ﻿

(Peer reviewed; Journal article, 2018)
In neutral helium atom microscopy, a beam of atoms is scanned across a surface. Though still in its infancy, neutral helium microscopy has seen a rapid development over the last few years. The inertness and low energy of ...
• #### Features concerning capillary pressure and the effect on two-phase and three-phase flow ﻿

(Conference object, 2008-04-30)
The effect of capillary pressure related to immiscible WAG (Water Alternate Gas) is studied by use of a numerical simulator. The capillary pressure is found to have a significant effect on the pressure gradient and the ...
