Positronium interactions in liquids and porous substances

In this article, its interaction is focused on two media that are important from the perspective of bio-chemical and technological studies, namely Ps-electron acceptor bound state formation in liquids (specially hydrogen bonding solvents) and also on a variety of porous material which are applicable in chemical/biochemical separations and other applications in technology. The underlying physical phenomenology in each case is separately dealt with giving suitable examples.
