Scope:
In nonequilibrium plasma reaction fields, energy can be selectively injected into specific degrees of freedom, enabling material circulation processes that are difficult to achieve with conventional technologies. At the same time, the coexistence of numerous non‑independent distributions (meta‑distributions) makes first‑principles control extremely challenging.
This symposium focuses on material circulation uniquely enabled by plasma processes and the associated measurement and evaluation of underlying distributions. By surveying environmental impacts and implementation potential, and together with perspectives on which distributions should be understood and controlled at what precision, we will discuss the potential of plasma‑based material circulation for building a sustainable society.
