要旨

Supercooled sulfuric acid solution droplets are a major constituent of the stratospheric background aerosol. We report the rate of homogeneous freezing and the crystallization dynamics of single levitated sulfuric acid solution droplets with 0 to 57.6 wt.% H2SO4. The energy of formation of the critical nucleus and the self-diffusion activation energy are deduced from the experiments as a function of temperature and concentration. The results are compared to both theoretical and experimental work of other groups.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
