DOI: 10.1016/j.apsusc.2017.11.080
Abstract: Abstract An unsolved problem in research of sputtering from metals induced by energetic large cluster ions is that molecular dynamics (MD) simulations often produce sputtering yields much higher than experimental results. Different from the previous… read more here.

DOI: 10.5194/acp-23-5279-2023
Abstract: Abstract. Atmospheric cluster ions are important constituents in the atmosphere, and their concentrations and compositions govern their role in atmospheric chemistry. However, there is currently limited quantitative research on atmospheric ion compositions, sources, and sinks,… read more here.
