Positronium Chemistry in Nano-scale Polymeric, Membrane, and Biological Systems

摘要

Positron and Positronium chemistry has been pursued and advanced by many scientists and engineers in both fundamental understanding of Positronium atom and its applications to chemical and polymeric systems during the last decade [1]. This presentation will focus on our recently collaborative investigations of positron annihilation in nano-scale polymers and composites, polymeric membranes, drug delivery polymers, and cancerous systems [2-5]. Promising advancements in Positronium chemistry using intense tunable slow positron beams will be presented. Future aspects of positron annihilation in the disciplines of chemistry, nanotechnology, chemical engineering, materials science, energy research, molecules with positrons, biological and medical sciences will be discussed.
