Full Description
These proceedings, comprising 66 peer-review papers, are divided into 10 chapters covering: fundamental aspects (of positron and positronium chemistry), membranes, molecular systems, confined systems, liquids, polymers, porous systems, non-metallic materials, nuclear materials, experimental techniques. This work owes a lot to the authors' commitment to positron and positronium chemistry and related subjects.
Volume is indexed by Thomson Reuters CPCI-S (WoS).
