Abstract

Fast dynamics (down to 10 ms) during exposure to changing relative humidity of single optically trapped K2CO3 particles were observed in the submicron to micron size range with time-resolved broadband light scattering and Raman spectroscopy. The study shows that complex multiple processes accompany efflorescence and deliquescence of unsupported aerosol particles. Efflorescence can occur in a single process in less than 10 ms (prompt) or proceed via multiple successive processes (multistep) that can last up to more than 10 seconds. The efflorescence relative humidity lies in the range of 9 to 25%. Raman spectra of the effloresced particles reveal that the final state of the particle is independent of the pathway. Deliquescence cycles start with an initial uptake of water followed by multiple complex processes which end at the deliquescence relative humidity (44–50%). The study reveals that complex multiple processes during phase transitions are not limited to deposited particles where heterogeneous processes may occur or large particles in the upper micrometer size range as previously observed.

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.
